Expense Narrative [Text Block] rr_ExpenseNarrativeTextBlock
The following table describes the fees and expenses you may pay if you buy, hold, and sell shares of the Fund (“Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below.
Operating Expenses Caption [Text] rr_OperatingExpensesCaption Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. For the fiscal year ended October 31, 2023, the Fund’s portfolio turnover rate was 27% of the average value of its portfolio.

Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock The following example is intended to help retail investors compare the cost of investing in the Fund with the cost of investing in other funds. It illustrates the hypothetical expenses that such investors would incur over various periods if they were to invest $10,000 in the Fund for the time periods indicated and then redeem all of the Shares at the end of those periods. This example assumes that the Fund provides a return of 5% a year and that operating expenses remain the same.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund employs a “passive management” (or indexing) investment approach designed to track the total return performance, before fees and expenses, of the Index. The Index is based on a proprietary methodology developed by SL Advisors, LLC, the Fund’s Index Provider (the “Index Provider”) and the investment adviser to the Predecessor Fund (as defined below), which is not affiliated with the Fund, its distributor, or Pacer Advisors, Inc., the Fund’s investment adviser (the “Adviser”).
The Index
The Index uses a proprietary, rules-based methodology to measure the performance of a portfolio of U.S. and Canadian exchange-listed equity securities of companies that generate a majority of their cash flow from certain qualifying “midstream” energy infrastructure activities. The companies in the Index are expected to benefit from regulatory policies favoring and industry trends toward American energy independence (i.e., a reduced or eliminated need for the United States to import fuels, such as coal, crude oil, or natural gas).
Midstream energy infrastructure refers to the processing, storage, transportation, and distribution of crude oil, natural gas, refined products, and their related products, as well as the transmission or storage of renewable energy. The following activity segments are considered qualifying midstream energy infrastructure activities: gathering & processing, compression, fractionation, logistics, midstream services, pipeline transportation, storage and terminalling of oil, gas, natural gas liquids, and refined products, as well as operating liquid natural gas facilities. The following activity segments are not qualifying activities: refining, shipping, exploration, production, retail distribution, or oil services. The Index may include small-, mid-, and large-capitalization companies.
The Index includes securities across the following categories of midstream companies. Such categories and the “weight” (defined as the percentage of the total Index) assigned to each category at the time of each rebalance of the Index are as follows:
U.S. & Canadian Midstream Companies (80%)
U.S.- or Canadian-listed companies that (i) have their principal place of business in the United States or Canada, (ii) elect to be treated as a corporation for U.S. or Canadian federal income tax purposes, and (iii) generate a majority of their cash flow or revenue from midstream energy infrastructure related activities.
U.S. Midstream MLPs* (20%)
U.S.-listed Midstream MLPs that (i) have their principal place of business in the United States, (ii) elect to be treated as a partnership for U.S. federal income tax purposes, (iii) do not pay incentive distribution rights (“IDRs”), and (iv) are not affiliates of MLP GPs that are owned in the Index.
* If an MLP that would be included in the Index has a tracking stock that is a corporation or elects to be taxed as a corporation, then such tracking stock will be included in the Index in place of the MLP and will use the MLP’s adjusted market capitalization for calculating its weight.
MLPs are publicly traded partnerships that receive at least 90% of their income from certain qualifying sources, such as natural resource-based midstream energy infrastructure activities. The equity interests, or units, of an MLP trade on public securities exchanges exactly like the shares of a corporation, without entity level taxation. An MLP typically consists of a general partner and limited partners. The operations and management of the MLP are controlled by the general partner, and the general partner typically has an ownership stake in the MLP and may have certain preferential rights to income from the MLP, such as IDRs. IDRs provide their owner with a larger share of the aggregate cash distributions made by a company once such distributions increase to certain specified levels and are designed to provide the holder of the IDRs with a strong incentive to increase the MLP’s aggregate cash distributions. 
At the time of each quarterly rebalance of the Index, each company meeting the Index’s criteria for the above categories is included in the Index, provided that the company has a minimum market capitalization of $500 million.
The Index is rebalanced quarterly, effective on the last trading day of each calendar quarter. Within each of the above categories, Index constituents are weighted based on their free-float market capitalization (i.e., market capitalization based on the number of shares available to the public), subject to the following constraints as of the time of each rebalance. Each individual Index constituent is limited to a weight of 7.25%, and any excess weight is redistributed equally among the other companies in the same category first and then to the remaining companies as needed.
Additionally, the aggregate weight of companies with individual weights greater than 5% (“5% Companies”) may not exceed 45% as of the time of each rebalance. If the aggregate weight of the 5% Companies would exceed 45%, the excess weight will be redistributed proportionally to companies with a weight of less than 4.25%. If at the time of a rebalance a company’s weight would be between 4.25% and 5%, the company’s weight will be reduced to 4.25% and the excess redistributed to companies in the same category with a weight of less than 4.25%.
As of February 2, 2024, the Index included securities of 29 companies. The Index was developed by the Index Provider in 2017 in anticipation of the commencement of operations of the Predecessor Fund (as defined below).
The Fund’s Investment Strategy
The Fund attempts to invest all, or substantially all, of its assets in the component securities that make up the Index. The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better. The Fund will generally use a “replication” strategy to achieve its investment objective,
meaning it will invest in all of the component securities of the Index in the same approximate proportion as in the Index. The Fund is non-diversified and therefore may invest a larger percentage of its assets in the securities of a single company than diversified funds. 
To the extent the Index concentrates (i.e., holds more than 25% of its total assets) in the securities of a particular industry or group of related industries, the Fund will concentrate its investments to approximately the same extent as the Index. The Index, and consequently the Fund, is expected to generally be concentrated in midstream energy infrastructure companies.

Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock
The Fund is the successor to the investment performance of the American Energy Independence ETF, a series of ETF Series Solutions (the “Predecessor Fund”), as a result of the reorganization of the Predecessor Fund into the Fund at the close of business on December 13, 2019. Accordingly, any performance information for periods prior to December 16, 2019 is that of the Predecessor Fund. The Predecessor Fund was managed by SL Advisors, LLC and sub-advised by Penserra Capital Management LLC and had the same investment objective, strategies, and policies as the Fund since the Predecessor Fund’s inception in December 2017.
The following performance information indicates some of the risks of investing in the Fund. The bar chart shows the Fund’s performance (or the Predecessor Fund’s performance, as applicable) for each full calendar year since inception. The table illustrates how the Fund’s (or the Predecessor Fund’s, as applicable) average annual returns for the one-year, five-year, and since inception periods compare with those of a broad measure of market performance and the Index. The Fund’s past performance, before and after taxes, does not necessarily indicate how it will perform in the future. Updated performance information is also available on the Fund’s website at www.PacerETFs.com.

Pacer American Energy Independence ETF | Concentration In The Energy Infrastructure Industry Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Concentration in the Energy Infrastructure Industry Risk. The Fund’s investments will be concentrated in an industry or group of industries to the extent the Index is so concentrated, and the Index is expected to be concentrated in midstream energy infrastructure companies. When the Fund focuses its investments in the energy infrastructure industry, financial, economic, business, and other developments affecting issuers in that industry, market, or economic sector will have a greater effect on the Fund than if it had not done so.Companies in the energy infrastructure industry are subject to many risks that can negatively impact the revenues and viability of companies in this industry, including, but not limited to, risks associated with companies owning and/or operating pipelines, gathering and processing assets, power infrastructure, propane assets, as well as capital markets, terrorism, natural disasters, climate change, operating, regulatory, environmental, supply and demand, and price volatility risks. The volatility of energy commodity prices can significantly affect energy companies due to the impact of prices on the volume of commodities developed, produced, gathered, and processed. Historically, energy commodity prices have been cyclical and exhibited significant volatility, which may adversely impact the value, operations, cash flows, and financial performance of energy companies. The volatility of energy commodity prices can also indirectly affect certain entities that operate in the midstream segment of the energy industry due to the impact of prices on the volume of commodities transported, processed, stored, or distributed.
Pacer American Energy Independence ETF | Currency Exchange Rate Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Currency Exchange Rate Risk. The Fund invests a significant percentage of its assets in investments denominated in Canadian dollars or in securities that provide exposure to such currency. Changes in currency exchange rates and the relative value of the Canadian dollar to the U.S. dollar will affect the value of the Fund’s investment and the value of your Shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.
Pacer American Energy Independence ETF | Equity Market Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors or companies in which the Fund invests. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.

Risk [Text Block] rr_RiskTextBlock ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks:
◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
◦Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.
◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Certain securities held by the Fund may trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, and the Fund may experience premiums and discounts greater than those of ETFs that hold securities that are traded only in the United States.
◦Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as NYSE Arca, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

Risk [Text Block] rr_RiskTextBlock Foreign Securities Risk. Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to political or economic instability. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments.

Risk [Text Block] rr_RiskTextBlock Geographic Concentration Risk. To the extent the Fund invests a significant portion of its assets in the securities of companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region. The Index’s, and therefore the Fund’s, heavy equity exposure to Canada subjects the Fund to a higher degree of country risk than that of more geographically diversified international funds. ◦Canada-Specific Risk. The Canadian economy is reliant on the sale of natural resources and commodities, which can pose risks such as the fluctuation of prices and the variability of demand for exportation of such products. Changes in spending on Canadian products by the economies of other countries or changes in any of these economies may cause a significant impact on the Canadian economy.

Risk [Text Block] rr_RiskTextBlock Index Provider Risk. There is no assurance that the Index Provider or any agents that act on its behalf, will compile the Index accurately, or that the Index will be determined, maintained, constructed, rebalanced, calculated or disseminated accurately. The Fund relies upon the Index Provider and its agents to compile, determine, maintain, construct, rebalance, calculate (or arrange for an agent to calculate), and disseminate the Index accurately. Any losses or costs associated with errors made by the Index Provider or its agents generally will be borne by the Fund and its shareholders. Because the Index includes international securities, the Index Provider may have limited information or may be more prone to mistakes based on the data available and such mistakes may have a greater impact on the Fund’s performance, which may increase the risks to the Fund.
Pacer American Energy Independence ETF | MLP Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock MLP Risk. MLP investment returns are enhanced during periods of declining or low interest rates and tend to be negatively influenced when interest rates are rising. In addition, most MLPs are fairly leveraged and typically
carry a portion of a “floating” rate debt. As such, a significant upward swing in interest rates would also drive interest expense higher. Furthermore, most MLPs grow by acquisitions partly financed by debt, and higher interest rates could make it more difficult to make acquisitions. MLP investments also entail many of the general tax risks of investing in a partnership. Limited partners in an MLP typically have limited control and limited or no rights to vote on matters affecting the partnership. Additionally, there is always the risk that an MLP will fail to qualify for favorable tax treatment.
Pacer American Energy Independence ETF | Risk Nondiversified Status [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Non-Diversification Risk. Although the Fund intends to invest in a variety of securities and instruments, the Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.
Pacer American Energy Independence ETF | Passive Investment Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Passive Investment Risk. The Fund is not actively managed and the Adviser would not sell a security due to current or projected underperformance of a security, industry or sector, unless that security is removed from the Index or the selling of shares of that security is otherwise required upon a reconstitution of the Index in accordance with the Index methodology. The Fund invests in securities included in the Index, regardless of their investment merits. The Fund does not take defensive positions under any market conditions, including conditions that are adverse to the performance of the Fund.
Pacer American Energy Independence ETF | Sector Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors.
◦Energy Sector Risk. The Fund may invest in companies in the energy sector, and therefore the performance of the fund could be negatively impacted by events affecting this sector. The profitability of companies in the energy sector is related to worldwide energy prices, exploration, and production spending. Such companies also are subject to risks of changes in exchange rates, government regulation, world events, depletion of resources and economic conditions, as well as market, economic and political risks of the countries where energy companies are located or do business. Oil and gas exploration and production can be significantly affected by natural disasters. Oil exploration and production companies may be adversely affected by changes in exchange rates, interest rates, government regulation, world events, and economic conditions. Oil exploration and production companies may be at risk for environmental damage claims.
The energy sector is comprised of energy, energy industrial, energy infrastructure and energy logistics companies, and will therefore be susceptible to adverse economic, environmental, business, regulatory or other occurrences affecting that sector. The energy sector has historically experienced substantial price volatility. At times, the performance of these investments may lag the performance of other sectors or the market as a whole. Master Limited Partnerships (MLPs) and other companies operating in the energy sector are subject to specific risks, including, among others, fluctuations in commodity prices; reduced consumer demand for commodities such as oil, natural gas or petroleum products; reduced availability of natural gas or other commodities for transporting, processing, storing or delivering; slowdowns in new construction; extreme weather or other natural disasters; and threats of attack by terrorists on energy assets. Additionally, energy sector companies are subject to substantial government regulation and changes in the regulatory environment for energy companies may adversely impact their profitability. MLPs may incur environmental costs and liabilities due to the nature of their businesses and the substances they handle. Changes in existing laws, regulations or enforcement policies governing the energy sector could significantly increase the compliance costs of MLPs. Certain MLPs could, from time to time, be held responsible for implementing remediation measures, the cost of which may not be recoverable from insurance. Over time, depletion of natural gas reserves and other energy reserves may also affect the profitability of energy companies.

Risk [Text Block] rr_RiskTextBlock Small and Mid-Sized Company Stock Risk. The Fund may invest in equity securities of small- or mid-sized (based on market capitalization) companies. Small to mid-sized company securities have historically been subject to greater investment risk than large company securities. The prices of small- to mid-sized company securities tend to be more volatile and less liquid than large company securities.
Pacer American Energy Independence ETF | Tax Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Tax Risk. The Fund intends to qualify for treatment as a “regulated investment company” (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”), by meeting certain source-of-income, asset diversification and annual distribution requirements. In particular, the Fund generally may not acquire a security if, as a result of the acquisition, more than 50% of the value of the Fund’s assets would be invested in (a) issuers in which the Fund has, in each case, invested more than 5% of the Fund’s assets or (b) issuers more than 10% of whose outstanding voting securities are owned by the Fund. Additionally, to qualify for treatment as a RIC the Fund may not invest more than 25% of its total assets in the securities of entities treated as qualified publicly traded partnerships (“QPTPs”) for U.S. federal income tax purposes, including certain MLPs. While the weighting of the Index is not inconsistent with these rules, given the concentration of the Index in a relatively small number of securities, it may not always be possible for the Fund to fully implement a replication strategy or a representative sampling strategy while satisfying these diversification requirements.
If the Fund were to fail to qualify as a RIC, the Fund would be subject to tax on its taxable income at corporate rates, and distributions from earnings and profits would generally be taxable to Fund shareholders as ordinary income. The Fund is also subject to the risk that MLPs in which the Fund invest will be classified as corporations rather than as partnerships for federal income tax purposes, which may reduce the Fund’s return and negatively affect the Fund’s net asset value. There is a risk of changes in tax laws or regulations, or interpretations thereof, which could adversely affect the Fund or the MLPs in which the Fund invests.
◦MLP Tax Risk. Depreciation or other cost recovery deductions passed through to the Fund from investments in MLPs in a given year will generally reduce the Fund’s taxable income, but those deductions may be recaptured in the Fund’s income in one or more subsequent years. When recognized and distributed, recapture income will generally be taxable to shareholders at the time of the distribution at ordinary income tax rates, even though those shareholders might not have held Shares at the time the deductions were taken by the Fund, and even though those shareholders will not have corresponding economic gain on their Shares at the time of the recapture. To distribute recapture income or to fund redemption requests, the Fund may need to liquidate investments. MLPs taxed as partnerships have historically made cash distributions to limited partners that exceed the amount of taxable income allocable to limited partners or members, due to a variety of factors, including significant non-cash deductions such as depreciation and depletion. These excess cash distributions would not be treated as income to the Fund but rather would be treated as a return of capital to the extent of the Fund’s basis in the MLP. As a consequence, the Fund may make distributions that exceed its earnings and profits, which would be recharacterized as a return of capital to shareholders. A return of capital distribution will generally not be taxable but will reduce each shareholder’s cost basis in Shares and result in a higher capital gain or lower capital loss when the Shares are sold. After a shareholder’s basis in Shares has been reduced to zero, distributions in excess of earnings and profits in respect of those Shares will be treated as gain from the sale of the Shares.

Depreciation or other cost recovery deductions passed through to the Fund from investments in MLPs in a given year will generally reduce the Fund’s taxable income, but those deductions may be recaptured in the Fund’s income in one or more subsequent years. When recognized and distributed, recapture income will generally be taxable to shareholders at the time of the distribution at ordinary income tax rates, even though those shareholders might not have held Shares at the time the deductions were taken by the Fund, and even though those shareholders will not have corresponding economic gain on their Shares at the time of the recapture.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. For the fiscal year ended October 31, 2023, the Fund’s portfolio turnover rate was 40% of the average value of its portfolio.

The Fund employs a “passive management” (or indexing) investment approach designed to track the total return performance, before fees and expenses, of the Index.
BlueStar Global Online Gambling, Video Gaming, and eSports Index
The Index is a rules-based index that consists of globally-listed stocks and depositary receipts of digital entertainment companies, as described below. Companies eligible to be added to the Index are those that derive at least 50% of their revenues from the following activities: online gambling platforms or software related to online gambling; video game development and software related to the development of video games or hardware such as computer processors and graphics cards used in video gaming systems, controllers, headsets, and gaming consoles; and streaming services or video games and/or hardware for use in eSports events or that are involved in eSports events such as league operators, teams, distributors and platforms, (collectively, “Digital Entertainment”) as determined by MV Index Solutions (the “Index Provider”).
To be added to the Index, an Index component must derive at least 50% of its revenue from Digital Entertainment; and must have a market capitalization greater than or equal to US$150 million; a three-month average-daily-value-traded of at least US$1 million at the current reconstitution and also at the previous two quarters; and average monthly volume of at least 250,000 shares over the last six months at the current reconstitution and also at the previous two quarters. Current components are eligible to remain in the Index if they derive at least 25% of their revenue from Digital Entertainment; and they meet the following reduced thresholds: a market capitalization exceeding US$75 million; a three-month average-daily-trading value of at least US$600,000 at the current reconstitution or at one of the previous two quarters; and at least 200,000 shares traded per month over the last six months at the current reconstitution or at one of the previous two quarters. The above criteria are referred to as the Index’s “Investibility Requirements.” The Index may include companies of any market capitalization that meets the Investibility Requirements, but has significant exposure to large- and mid-capitalization companies.
Index components are divided into two tiers: The first tier consists of companies that develop or operate online gambling or betting platforms or related software (“Online Gambling Companies”). The second tier consists of companies that (i) develop and/or publish video games, facilitate the streaming or distribution of video games, or produce hardware used in video games (e.g., computer processors and graphics cards used in video gaming systems, controllers, headsets, and gaming consoles); (ii) develop or operate streaming services, video games, or hardware for use in eSports events; or (iii) are involved in eSports events, such as league operators, teams, distributors, and platforms (collectively, “eSports Companies”). eSports are a form of competition using video games, often taking the form of organized, multiplayer video game competitions, and eSports companies include augmented and virtual reality video games.
At the time of each quarterly rebalance and reconstitution of the Index, companies meeting the Investibility Requirements are added to the Index based on their free-float market capitalization (from largest to smallest) until the aggregate free-float market capitalization of companies in the Index from the applicable tier is at least 90% of the free-float market capitalization of all companies from such tier that meet the Investibility Requirements. For example, if the aggregate free-float market capitalization of all eSports Companies meeting the Investibility Requirements was US$1.5 trillion, the largest eSports Companies meeting the Investibility Requirements would be included in the Index until their aggregate free-float market capitalization was at least US$1.35 trillion. The next largest company from each tier will continue to be added to the Index until at least 25 companies from each tier are included.
At the time of each quarterly review of the Index, each tier is assigned a weight of 50%. Within each tier, companies in the Index are initially weighted by their float-adjusted market capitalization, subject to a maximum weight of 8% for any individual security (3% for companies in the semiconductor industry) and adjustments downward based on certain liquidity criteria. Excess weight resulting from any such adjustments is redistributed among the remaining constituents in the applicable tier equally. The aggregate weight of constituents with a weight of 5% or greater is capped at 50%. In addition, the aggregate weight of companies earning less than 50% of their revenues from Digital Entertainment is capped at 20%.
The Index is rebalanced and reconstituted quarterly after the close of business on the third Friday of March, June, September, and December based on the data of the Wednesday prior to the second Friday of such reconstitution month.
As of February 2, 2024, the Index was composed of 47 constituents, 29 of which were listed on a non-U.S. exchange. The Index was established in 2022 and is owned and maintained by the Index Provider.
The Fund’s Investment Strategy
The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better. The Fund will generally use a “replication” strategy to achieve its investment objective, meaning it will invest in all of the component securities of the Index.
Under normal circumstances, at least 80% of the Fund’s net assets (plus any borrowings for investment purposes) will be invested in companies that derive at least 50% of their revenues from Digital Entertainment, as defined above.
As of February 2, 2024, the Index had significant exposure to the consumer discretionary and communication services sectors and significant exposure to European companies. To the extent the Index concentrates (i.e., holds more than 25%
of its total assets) in the securities of a particular industry or group of related industries, the Fund will seek to concentrate its investments to approximately the same extent as the Index. The Index, and consequently the Fund, is expected to be concentrated in Digital Entertainment companies. The Fund is non-diversified and therefore may invest a larger percentage of its assets in the securities of a single issuer or small number of issuers than diversified funds.

Risk [Text Block] rr_RiskTextBlock Concentration in Digital Entertainment Companies Risk. Companies in the business of betting or online gambling include those directly engaged in casino operations, racetrack operations, sports and horse race betting operations, and online betting operations. Online Gambling Companies face intense competition and are highly regulated. These companies face regulatory challenges and heightened competition as more states begin to allow betting and online gambling activities.
eSports Companies are subject to intense global competition and may be smaller companies with limited product lines, markets, financial resources, or personnel. Such companies may be heavily dependent on patent and intellectual property rights and may be prone to operational and information security risks resulting from cyber-attacks and/or technological malfunctions. eSports Companies may have products that face rapid obsolescence and may be dependent on one or a small number of products or product franchises for a significant portion of their revenue and profits. They may also be subject to shifting consumer preferences, including preferences with respect to gaming console platforms and other forms of entertainment, and changes in consumer discretionary spending, all of which may change rapidly and cannot necessarily be predicted. eSports Companies are also subject to increasing regulatory constraints, particularly with respect to cybersecurity and privacy, and may be subject to sophisticated intellectual property infringement schemes and piracy efforts.

The Fund may invest a significant percentage of its assets in investments denominated in a foreign currency or in securities that provide exposure to such currency. Changes in currency exchange rates and the relative value of such currency to the U.S. dollar will affect the value of the Fund’s investment and the value of your Shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.

Risk [Text Block] rr_RiskTextBlock Depositary Receipt Risk. Depositary Receipts involve risks similar to those associated with investments in foreign securities, such as changes in political or economic conditions of other countries and changes in the exchange rates of foreign currencies. Depositary Receipts listed on U.S. exchanges are issued by banks or trust companies and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares (“Underlying Shares”). When the Fund invests in Depositary Receipts as a substitute for an investment directly in the Underlying Shares, the Fund is exposed to the risk that the Depositary Receipts may not provide a return that corresponds precisely with that of the Underlying Shares.

Risk [Text Block] rr_RiskTextBlock Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors or companies in which the Fund invests. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.
Pacer BlueStar Digital Entertainment ETF | ETF Risks Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks:
◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of
market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
◦Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.
◦Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.
◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Because certain securities held by the Fund trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, the Fund is likely to experience premiums and discounts greater than those of domestic ETFs.
◦Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as The Nasdaq Stock Market LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

Pacer BlueStar Digital Entertainment ETF | Foreign Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Foreign Securities Risk. Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to political or economic instability. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments. Companies in many foreign markets are not subject to the same degree of regulatory requirements, accounting standards or auditor oversight as companies in the U.S., and as a result, information about the securities in which the Fund invests may be less reliable or complete. Foreign markets often have less reliable securities valuations and greater risk associated with the custody of securities than the U.S. There may be significant obstacles to obtaining information necessary for investigations into or litigation against companies and shareholders may have limited legal remedies.
Pacer BlueStar Digital Entertainment ETF | Geographic Concentration Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Geographic Concentration Risk. To the extent the Fund invests a significant portion of its assets in the securities of companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region. The Index’s, and therefore the Fund’s, heavy equity exposure to China and Europe subjects the Fund to a higher degree of country risk than that of more geographically diversified international funds.
◦Risks of Investing in China. Investments in Chinese issuers subject the Fund to risks specific to China. China may be subject to considerable degrees of economic, political and social instability. China is a developing market and demonstrates significantly higher volatility from time to time in comparison to developed markets. Over the past 25 years, the Chinese government has undertaken reform of economic and market practices and is expanding the sphere of private ownership of property in China. However, Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability. Internal social unrest or confrontations with other neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency convertibility, interest rate fluctuations and higher rates of inflation. Export growth continues to be a major driver of China’s rapid economic growth. Reduction in spending on Chinese products and services, institution of tariffs or other trade barriers, or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the Chinese economy. China is also vulnerable economically to the impact of a public health crisis, which could depress consumer demand, reduce economic output, and potentially lead to market closures, travel restrictions, and quarantines, all of which would negatively impact China’s economy and could affect the economies of its trading partners.
◦Risks Related to Investing in Europe. The economies and markets of European countries are often closely connected and interdependent, and events in one country in Europe can have an adverse impact on other European countries. The Fund makes investments in securities of issuers that are domiciled in, or have significant operations in, member countries of the European Union (“EU”) that are subject to economic and monetary controls that can adversely affect the Fund’s investments. The European financial markets have experienced volatility and adverse trends in recent years and these events have adversely affected the exchange rate of the euro and may continue to significantly affect other European countries. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners, including some or all of the European countries in which the Fund invests.
The UK formally exited from the EU on January 31, 2020 (known as “Brexit”), and effective December 31, 2020, the UK ended a transition period during which it continued to abide by the EU’s rules and the UK’s trade relationships with the EU were generally unchanged. Following this transition period, the impact on the UK and European economies and the broader global economy could be significant, resulting in negative impacts, such as increased volatility and illiquidity, and potentially lower economic growth of markets in the UK, Europe and globally, which may adversely affect the value of the Fund’s investments.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Risks of Investing in China. Investments in Chinese issuers subject the Fund to risks specific to China. China may be subject to considerable degrees of economic, political and social instability. China is a developing market and demonstrates significantly higher volatility from time to time in comparison to developed markets. Over the past 25 years, the Chinese government has undertaken reform of economic and market practices and is expanding the sphere of private ownership of property in China. However, Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability. Internal social unrest or confrontations with other neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency convertibility, interest rate fluctuations and higher rates of inflation. Export growth continues to be a major driver of China’s rapid economic growth. Reduction in spending on Chinese products and services, institution of tariffs or other trade barriers, or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the Chinese economy. China is also vulnerable economically to the impact of a public health crisis, which could depress consumer demand, reduce economic output, and potentially lead to market closures, travel restrictions, and quarantines, all of which would negatively impact China’s economy and could affect the economies of its trading partners.

Risk [Text Block] rr_RiskTextBlock Index Provider Risk. There is no assurance that the Index Provider or any agents that act on its behalf, will compile the Index accurately, or that the Index will be determined, maintained, constructed, rebalanced, calculated or disseminated accurately. The Fund relies upon the Index Provider and its agents to compile, determine, maintain, construct, rebalance, calculate (or arrange for an agent to calculate), and disseminate the Index accurately. Any losses or costs associated with errors made by the Index Provider or its agents generally will be borne by the Fund and its shareholders. Because the Index includes international securities, the Index Provider may have limited information or may be more prone to mistakes based on the data available and such mistakes may have a greater impact on the Fund’s performance, which may increase the risks to the Fund.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Non-Diversification Risk. Although the Fund intends to invest in a variety of securities and instruments, the Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.

Communications services companies are subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new adverse regulatory requirements may adversely affect the business of the such companies. Companies in the communications services sector can also be significantly affected by intense competition, including competition with alternative technologies such as wireless communications (including with 5G and other technologies), product compatibility, consumer preferences, rapid product obsolescence, and research and development of new products. Technological innovations may make the products and services of such companies obsolete.
◦Consumer Discretionary Sector Risk. The Fund may invest in companies in the consumer discretionary sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns.

The Fund employs a “passive management” (or indexing) investment approach designed to track the total return performance, before fees and expenses, of the Index.
BlueStar Robotics and 3D Printing Index
The Index is a rules-based index that consists of globally-listed stocks and depositary receipts of companies that, at the time of being added to the Index, derive at least 50% of their revenues (25% for current Index components) from robots or manufacturing automation equipment (“robotics”); computer aided design (“CAD”) software; or 3D printing centers, 3D printing hardware, 3D printing simulation software, 3D scanning and measurement software, and 3D printing materials (collectively, “Robotics and 3D Printing Companies”), as determined by MV Index Solutions (the “Index Provider”).
To be added to the Index, an Index component must have a market capitalization greater than or equal to US$500 million; a three-month average-daily-value-traded of at least US$1 million at the current reconstitution and also at the previous two quarters; and average monthly volume of at least 250,000 shares over the last six months at the current reconstitution and also at the previous two quarters. Current components will remain eligible for selection to the Index if they meet the following, reduced thresholds: a market capitalization exceeding US$250 million; a three-month average-daily-value-traded of at least US$500,000 in at least two of the latest three quarters (including the current reconstitution); and a three-month average-daily-trading value of at least US$750,000 at the current reconstitution or at one of the previous two quarters. The above criteria are referred to as the Index’s “Investibility Requirements.” The Index may include companies
of any market capitalization that meets the Investibility Requirements, but has significant exposure to large- and mid-capitalization companies.
At the time of each semi-annual reconstitution of the Index, the Index components are initially weighted by their float-adjusted market capitalization within three tiers:
Tier 1 Robotics and Manufacturing Automation Equipment (50% weight): includes companies that derive at least 50% of their revenues (25% for current components) from the development of industrial or agricultural robots and production systems, automated inventory management, voice/image/text recognition solutions for the industrial market, and medical robots or robotic instruments (“Robotics Companies”). “Robotics” involves the design, construction, and operation of machines that perform tasks that would otherwise be done by humans.
Tier 2 3D Printing (25% weight): includes companies that derive at least 50% of their revenues (25% for current components) from the following business lines: 3D printing hardware, 3D printing simulation software, 3D printing centers, 3D scanning and measurement software (e.g., software used for creating 3D models, augmented reality, motion capture, robotic mapping, and 3D printing), and 3D printing materials.
Tier 3 Computer Aided Design Software (25% weight): includes companies that derive at least 50% of their revenues (25% for current components) from: development of CAD software to aid in the creation, modification, analysis, or optimization of a design. CAD software has many uses, including applications in the automotive, shipbuilding, and aerospace industries. CAD software is also used in industrial and architectural design, medical device design, and digital content creation (e.g., computer animation for special effects).
At the time of each semi-annual rebalance and reconstitution of the Index, Robotics and 3D Printing Companies meeting the Investibility Requirements are added to the Index based on their free-float market capitalization (from largest to smallest) until the aggregate free-float market capitalization of companies in the Index from the applicable tier is at least 98% of the free-float market capitalization of all companies from such tier that meet the Investibility Requirements. For example, if the aggregate free-float market capitalization of all Robotics Companies meeting the Investibility Requirements was US$1 trillion, the largest Robotics Companies meeting the Investibility Requirements would be included in the Index until their aggregate free-float market capitalization was at least US$980 billion. The next largest company from each tier will continue to be added to the Index until at least 25 Robotics Companies, ten 3D Printing companies, and ten CAD Software companies are included.
Index components are subject to a maximum weight of 8% for any individual security and adjustments downward based on certain liquidity criteria. An additional rule is applied to ensure that the aggregate weight of constituents with a weight of 5% or greater does not exceed 50%.
The Index is rebalanced and reconstituted semi-annually after the close of business on the third Thursday of June and December based on the data of the first Thursday of such reconstitution month.
As of February 2, 2024, the Index was composed of 55 constituents, 28 of which were listed on a non-U.S. exchange. The Index was established in 2022 and is owned and maintained by the Index Provider.
The Fund’s Investment Strategy
The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better. The Fund will generally use a “replication” strategy to achieve its investment objective, meaning it will invest in all of the component securities of the Index.
As of February 2, 2024, the Index had significant exposure to the industrials and information technology sectors and had significant exposure to Japanese and European companies. To the extent the Index concentrates (i.e., holds more than 25% of its total assets) in the securities of a particular industry or group of related industries, the Fund will seek to concentrate its investments to approximately the same extent as the Index. The Index, and consequently the Fund, is expected to be concentrated in Robotics and 3D Printing Companies. The Fund is non-diversified and therefore may invest a larger percentage of its assets in the securities of a single issuer or small number of issuers than diversified funds.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Concentration in Robotics and 3D Printing Companies Risk. The Robotics and 3D Printing industry can be significantly affected by intense competition, aggressive pricing, technological innovations, and product obsolescence. Companies in the software industry are subject to significant competitive pressures, such as aggressive pricing, new market entrants, competition for market share, short product cycles due to an accelerated rate of technological developments and the potential for limited earnings and/or falling profit margins. These companies also face the risks that new services, equipment or technologies will not be accepted by consumers and businesses or will become rapidly obsolete. These factors can affect the profitability of these companies and, as a result, the value of their securities. Also, patent protection is integral to the success of many companies in this industry, and profitability can be affected materially by, among other things, the cost of obtaining (or failing to obtain) patent approvals, the cost of litigating patent infringement and the loss of patent protection for products (which significantly increases pricing pressures and can materially reduce profitability with respect to such products). In addition, many software companies have limited operating histories. Prices of these companies’ securities historically have been more volatile than other securities, especially over the short term.

Risk [Text Block] rr_RiskTextBlock Currency Exchange Rate Risk. The Fund may invest a significant percentage of its assets in investments denominated in a foreign currency or in securities that provide exposure to such currency. Changes in currency exchange rates and the relative value of such currency to the U.S. dollar will affect the value of the Fund’s investment and the value of your Shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.

Risk [Text Block] rr_RiskTextBlock Depositary Receipt Risk. Depositary Receipts involve risks similar to those associated with investments in foreign securities, such as changes in political or economic conditions of other countries and changes in the exchange rates of foreign currencies. Depositary Receipts listed on U.S. exchanges are issued by banks or trust companies and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares (“Underlying Shares”). When the Fund invests in Depositary Receipts as a substitute for an investment directly in the Underlying Shares, the Fund is exposed to the risk that the Depositary Receipts may not provide a return that corresponds precisely with that of the Underlying Shares.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors or companies in which the Fund invests. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.

Risk [Text Block] rr_RiskTextBlock ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks:
◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
◦Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.
◦Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.
◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Because certain securities held by the Fund trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, the Fund is likely to experience premiums and discounts greater than those of domestic ETFs.
◦Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as The Nasdaq Stock Market LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

Risk [Text Block] rr_RiskTextBlock Foreign Securities Risk. Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to political or economic instability. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments. Companies in many foreign markets are not subject to the same degree of regulatory requirements, accounting standards or auditor oversight as companies in the U.S., and as a result, information about the securities in which the Fund invests may be less reliable or complete. Foreign markets often have less reliable securities valuations and greater risk associated with the custody of securities than the U.S. There may be significant obstacles to obtaining information necessary for investigations into or litigation against companies and shareholders may have limited legal remedies.
Pacer BlueStar Engineering the Future ETF | Geographic Concentration Risk Member

Risk [Text Block] rr_RiskTextBlock Geographic Concentration Risk. To the extent the Fund invests a significant portion of its assets in the securities of companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region. The Index’s, and therefore the Fund’s, heavy equity exposure to Japan and Europe subjects the Fund to a higher degree of country risk than that of more geographically diversified international funds.
◦Risks Related to Investing in Europe. The economies and markets of European countries are often closely connected and interdependent, and events in one country in Europe can have an adverse impact on other European countries. The Fund makes investments in securities of issuers that are domiciled in, or have significant operations in, member countries of the European Union (“EU”) that are subject to economic and monetary controls that can adversely affect the Fund’s investments. The European financial markets have experienced volatility and adverse trends in recent years and these events have adversely affected the exchange rate of the euro and may continue to significantly affect other European countries. Decreasing imports or
exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners, including some or all of the European countries in which the Fund invests.
The UK formally exited from the EU on January 31, 2020 (known as “Brexit”), and effective December 31, 2020, the UK ended a transition period during which it continued to abide by the EU’s rules and the UK’s trade relationships with the EU were generally unchanged. Following this transition period, the impact on the UK and European economies and the broader global economy could be significant, resulting in negative impacts, such as increased volatility and illiquidity, and potentially lower economic growth of markets in the UK, Europe and globally, which may adversely affect the value of the Fund’s investments.
◦Risks Related to Investing in Japan. The Japanese economy may be subject to considerable degrees of economic, political and social instability, which could have a negative impact on Japanese securities. Since the year 2000, Japan’s economic growth rate has remained relatively low and it may remain low in the future. In addition, Japan is subject to the risk of natural disasters, such as earthquakes, volcanoes, typhoons and tsunamis. Additionally, decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rates, a recession in the United States or continued increases in foreclosure rates may have an adverse impact on the economy of Japan. Japan also has few natural resources, and any fluctuation or shortage in the commodity markets could have a negative impact on Japanese securities.

Although the Fund intends to invest in a variety of securities and instruments, the Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund employs a “passive management” (or indexing) investment approach designed to track the total return performance, before fees and expenses, of the Index. The Index is based on a proprietary methodology developed by Metaurus Advisors LLC (“Metaurus”), the Fund’s sub-adviser and the Fund’s index provider. All or a portion of the methodologies and algorithms used to calculate the Index are covered by one or more granted or pending U.S. patents owned by Metaurus.
The Index
The Index, as designed, has two components: (i) an S&P 500 Index component (the “S&P 500 Component”) and (ii) a dividend component (the “Dividend Component”) consisting of long positions in annual futures contracts that provide exposure to ordinary dividends paid on the common stocks of companies included in the S&P 500 (“S&P Dividend Futures”). The S&P 500 Index consists of approximately 500 leading U.S.-listed companies representing approximately 80% of the U.S. equity market capitalization. The Dividend Component is designed to give the Fund exposure to approximately 400% of the ordinary dividends the Fund would otherwise have expected to receive from its investment in the S&P 500 Component. The Dividend Component consists of annual futures contracts whose value represents the
market’s expectation of the amount of ordinary dividends to be paid by S&P 500 companies during the term of the futures contract. As of December 31, 2023, the S&P 500 Component comprised approximately 86% of the Index.
S&P Dividend Futures seek to allow investors in these instruments to obtain exposure to the actual dividend value that will be paid by the S&P 500 constituent companies over a period of time. The amount of such futures contracts will generally result in exposure to such dividends that is significantly greater than the amount of dividends that the Fund would normally receive from its direct investment in S&P 500 constituent companies (i.e., approximately 400% of such dividends that the Fund would normally have received). S&P Dividend Futures provide for the future sale by one party and purchase by another party of a specified dividend value of the S&P 500 at a specified future time and at a specified price. S&P Dividend Futures are standardized contracts traded on a recognized exchange. The Fund’s investment in S&P Dividend Futures will generally include the three most current annual S&P Dividend Futures contracts (e.g., in June 2021, the Fund would invest in the 2021, 2022, and 2023 contracts.
The Index is typically rebalanced each December, at the end of the trading day on which the current year’s S&P Dividend Futures expire. At each rebalancing date, the current year’s annual S&P Dividend Futures will be replaced by the then closest maturing contract in three years. On each Index rebalancing date, the composition of the Index is expected to change.
The Fund’s Investment Strategy
The Fund attempts to invest all, or substantially all, of its assets in the component securities that make up the Index. The Fund will generally use a “replication” strategy to achieve its investment objective, meaning it will seek to invest in all of the component securities of the Index in the same approximate proportion as in the Index. The Fund attempts to replicate the S&P 500 Component by investing in equity securities, long positions in futures contracts on the S&P 500, or exchange-traded funds that invest in common stocks that are included in the S&P 500. The Fund attempts to replicate the Dividend Component through long positions in exchange-traded S&P Dividend Futures.
To collateralize the Fund’s long positions in S&P Dividend Futures, the Fund typically holds U.S. Treasury securities with maturity dates similar to the expiration dates of the S&P Dividend Futures. The Fund may also collateralize the long positions with cash or cash equivalents. The Fund typically holds cash, cash equivalents, or U.S. Treasury securities in approximately the same amount as the notional value of the S&P Dividend Futures in order to offset any embedded leverage.
Under normal circumstances, at least 80% of the Fund’s net assets (plus any borrowings for investment purposes) will be invested in large cap equity securities that are principally traded in the United States and derivatives based on those securities. The Fund defines “equity securities” to mean common and preferred stocks, rights, warrants, depositary receipts, and ETFs. Additionally, the Fund defines “large cap” to mean a company included in the S&P 500.
The Fund is non-diversified and therefore may invest a larger percentage of its assets in the securities of a single issuer or small number of issuers than diversified funds.

Risk [Text Block] rr_RiskTextBlock Concentration Risk. If the Index concentrates in an industry or group of industries, the Fund’s investments may be concentrated accordingly. In such event, the value of the Fund’s shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries. In addition, at times, an industry or group of industries in which the Fund is concentrated may be out of favor and underperform other industries or groups of industries.
Pacer Metaurus US Large Cap Dividend Multiplier 400 ETF | Equity Market Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors or companies in which the Fund invests. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.
Pacer Metaurus US Large Cap Dividend Multiplier 400 ETF | Derivatives Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Derivatives Risk. Derivatives include instruments and contracts that are based on, and are valued in relation to, one or more underlying securities, financial benchmarks or indices, such as futures contracts. Derivatives typically have economic leverage inherent in their terms. Futures contracts can be highly volatile, illiquid, and difficult to value. Adverse changes in the value or level of the underlying asset or index, which the Fund may not directly own, can result in a loss to the Fund substantially greater than the amount invested in the derivative itself. The use of derivative instruments also exposes the Fund to additional risks and transaction costs. A risk of the Fund’s use of derivatives is that the fluctuations in their values may not correlate perfectly with the overall securities markets. A small position in futures contracts could have a potentially large impact on the Fund’s performance. Trading restrictions or limitations may be imposed by an exchange, and government regulations may restrict trading in futures contracts.

Risk [Text Block] rr_RiskTextBlock Dividends Risk. There can be no assurance that a dividend-paying company will continue to make regular dividend payments. The ability for a company to pay dividends is dependent on the economic climate and the companies’ current earnings and capital resources. Changes in economic conditions or a company’s earnings or financial resources could cause a company to reduce its dividend payments or suspend the payment of dividends altogether. The possibility that such companies could reduce or eliminate the payment of dividends in the future, especially if the companies are facing an economic downturn, could negatively affect the Fund’s performance.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks:
◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
◦Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.
◦Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.
◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant.
◦Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as NYSE Arca, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

Pacer Metaurus US Large Cap Dividend Multiplier 400 ETF | Futures Contract Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Futures Contract Risk. The primary risks associated with the use of futures contracts, which may adversely affect the Fund’s NAV and total return, are (a) the imperfect correlation between the change in market value of the instruments held by the Fund and the price of the futures contract; (b) possible lack of a liquid secondary market for a futures contract and the resulting inability to close a futures contract when desired; (c) the possibility that the counterparty will default in the performance of its obligations; and (d) if the Fund has insufficient cash, it may have to sell securities from its portfolio to meet daily variation margin requirements, and the Fund may have to sell securities at a time when it maybe disadvantageous to do so. The S&P Dividend Futures held by the Fund only reflect ordinary dividends paid on the common stocks included in the S&P 500. Any special dividends paid by a company will not be reflected in the settlement value of the S&P Dividend Futures. A special dividend is a non-recurring dividend distributed by a company that is separate from the regular cycle of dividends and may be larger than a company’s typical dividend payment, such as the spin-off of assets of the company being distributed to shareholders. The Fund may not perform as well if the actual future growth in dividends paid on common stocks is below the expected growth in dividends, as reflected in the market prices at which the Fund buys the S&P Dividend Futures.
Pacer Metaurus US Large Cap Dividend Multiplier 400 ETF | Government Obligations Risk Member

Risk [Text Block] rr_RiskTextBlock Government Obligations Risk. The Fund may invest in securities issued by the U.S. government. There can be no guarantee that the United States will be able to meet its payment obligations with respect to such securities. Additionally, market prices and yields of securities supported by the full faith and credit of the U.S. government may decline or be negative for short or long periods of time.

There is no assurance that Metaurus (the Fund’s index provider) or any agents that act on its behalf, will compile the Index accurately, or that the Index will be determined, maintained, constructed, rebalanced, calculated or disseminated accurately. The Fund relies upon Metaurus and its agents to compile, determine, maintain, construct, rebalance, calculate (or arrange for an agent to calculate), and disseminate the Index accurately. Any losses or costs associated with errors made by Metaurus or its agents generally will be borne by the Fund and its shareholders.
Pacer Metaurus US Large Cap Dividend Multiplier 400 ETF | Large-Capitalization Investing Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Large-Capitalization Investing Risk. The Fund may invest in the securities of large-capitalization companies. As a result, the Fund’s performance may be adversely affected if securities of large-capitalization companies underperform securities of smaller-capitalization companies or the market as a whole. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion.
Pacer Metaurus US Large Cap Dividend Multiplier 400 ETF | Limited Operating History Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Limited Operating History. The Fund is a recently organized management investment company with limited operating history. As a result, prospective investors have a limited track record on which to base their investment decision. An investment in the Fund may therefore involve greater uncertainty than an investment in a fund with a more established record of performance.
Pacer Metaurus US Large Cap Dividend Multiplier 400 ETF | Risk Nondiversified Status [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Non-Diversification Risk. Although the Fund intends to invest in a variety of securities and instruments, the Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.
Pacer Metaurus US Large Cap Dividend Multiplier 400 ETF | Other Investment Companies Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Other Investment Companies Risk. The Fund will incur higher and duplicative expenses when it invests in other investment companies such as ETFs. There is also the risk that the Fund may suffer losses due to the investment practices of the underlying funds. When the Fund invests in other investment companies, the Fund will be subject to substantially the same risks as those associated with the direct ownership of securities held by such investment companies. Investments in ETFs are also subject to the “ETF Risks” described above.
Pacer Metaurus US Large Cap Dividend Multiplier 400 ETF | Passive Investment Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Passive Investment Risk. The Fund is not actively managed and the Sub-Adviser would not sell a security due to current or projected underperformance of a security, industry or sector, unless that security is removed from the Index or the selling of shares of that security is otherwise required upon a reconstitution of the Index in accordance with the Index methodology. The Fund invests in securities included in the Index, regardless of their investment merits. The Fund does not take defensive positions under any market conditions, including conditions that are adverse to the performance of the Fund.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Tracking Error Risk. As with all index funds, the performance of the Fund and its Index may differ from each other for a variety of reasons. For example, the Fund incurs operating expenses and portfolio transaction costs not incurred by the Index. In addition, the Fund may not be fully invested in the securities of the Index at all times or may hold securities not included in the Index.

Risk [Text Block] rr_RiskTextBlock Trading Halt Risk. The Fund invests in futures contracts. The major exchanges on which these contracts are traded have established limits on how much the trading price of a futures contract may decline over various time periods within a day, and may halt trading in a contract that exceeds such limits. If a trading halt occurs, the Fund may temporarily be unable to purchase or sell certain securities.
