The Pacer Metaurus Nasdaq 100 Dividend Multiplier 600 ETF (the “Fund”) employs a “passive management” (or indexing) investment approach designed to track the total return performance, before fees and expenses, of the Metaurus Nasdaq Dividend Multiplier Total Return Index - Series 600 (the “Index”).

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. Because the Fund is newly organized, portfolio turnover information is not yet available.

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 Metaurus Advisors LLC (“Metaurus”), the Fund’s sub-adviser and the Fund’s index provider. Solactive AG serves as the calculation agent for the Index. Metaurus is not affiliated with Pacer Advisors, Inc., the Fund’s investment adviser. 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) a Nasdaq-100 component (the “Nasdaq-100 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 Nasdaq-100® Index (the “Nasdaq-100”). The Nasdaq-100 is designed to measure the performance of 100 of the largest non-financial companies by
modified market capitalization listed on the Nasdaq Global Select Market or the Nasdaq Global Market. The Nasdaq-100 generally includes securities issued by U.S. and non-U.S. issuers, including American Depositary Receipts (“ADRs”), common stocks, ordinary shares and tracking stocks; real estate investment trusts, special purpose acquisition companies and when-issued securities are not typically eligible for index inclusion. The Nasdaq-100 is reconstituted annually in December. The Dividend Component is designed to give the Fund exposure to approximately 600% of the ordinary dividends the Fund would otherwise have expected to receive from its investment in the Nasdaq-100 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 Nasdaq-100 companies during the term of the futures contract (“Nasdaq-100 Dividend Futures”). As of July 31, 2024, the Nasdaq-100 Component comprised approximately 88.7% of the Index.
Nasdaq-100 Dividend Futures seek to allow investors in these instruments to obtain exposure to the actual dividend value that will be paid by the Nasdaq-100 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 Nasdaq-100 constituent companies (i.e., approximately 600% of such dividends that the Fund would normally have received). Nasdaq-100 Dividend Futures provide for the future sale by one party and purchase by another party of a specified dividend value of the Nasdaq-100 at a specified future time and at a specified price. Nasdaq-100 Dividend Futures are standardized contracts traded on a recognized U.S. exchange. The Fund’s investment in Nasdaq-100 Dividend Futures will generally include the three most current annual Nasdaq-100 Dividend Futures contracts (e.g., in September 2024, the Fund would invest in the 2024, 2025, and 2026 contracts).
The Dividend Component will typically be comprised of the first three annual maturities of annual Nasdaq-100 Dividend Futures. The three annual Nasdaq-100 Dividend Futures that will comprise the Dividend Component at any time will typically have an equal-share representation within the Index. Specifically, the Dividend Component will be comprised of one contract of each maturity. The allocation (or weighting) within the Index between the Dividend Component and the Nasdaq-100 Component will be determined such that the Index’s total exposure to the ordinary dividends to be paid by the companies that comprise the Nasdaq-100 Index over the next three years will equal 600%.
Each December, upon the expiry of the current year’s annual Nasdaq-100 Dividend Futures contract, the Dividend Component within the Index will be reconstituted, and the then 3-year maturity annual contract will be incorporated to the Dividend Component. For example, in December of 2024, upon expiry, the 2024 annual Nasdaq-100 Dividend Futures contract will be removed from the Dividend Component and replaced with the 2027 annual Nasdaq-100 Dividend Futures contract. The Dividend Component will then be comprised of one contract each of the 2025, 2026, and 2027 maturities. Once the Dividend Component is reconstituted, the Index will be rebalanced and new weightings between the Dividend Component and the Nasdaq-100 Component will be established for the upcoming year. The new weightings will be determined such that, for the next year, the total exposure to the next three years of ordinary dividend to be paid by the companies in the Nasdaq-100 Index will be 600%.
The Index is rebalanced annually each December, at the end of the trading day on which the current year’s Nasdaq-100 Dividend Futures expire. At each rebalancing date, the Nasdaq-100 Component will be reconstituted to reflect the current Nasdaq-100 constituent companies and the current year’s annual Nasdaq-100 Dividend Futures will be replaced by the then closest maturing contract in three years. On the 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 Nasdaq-100 Component by investing in equity securities that are included in the Nasdaq-100, long positions in futures contracts on the Nasdaq-100, or exchange-traded funds (“ETFs”) that invest in the equity securities that are included in the Nasdaq-100. The Fund attempts to replicate the Dividend Component through long positions in exchange-traded Nasdaq-100 Dividend Futures.
To collateralize the Fund’s long positions in Nasdaq-100 Dividend Futures, the Fund may hold U.S. Treasury securities with maturity dates similar to the expiration dates of the Nasdaq-100 Dividend Futures. The Fund may also collateralize
the long positions with cash or cash equivalents. The Fund holds cash, cash equivalents, or U.S. Treasury securities in approximately the same amount as the notional value of the Nasdaq-100 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 a combination of large cap growth equity securities and dividend-paying large cap equity securities (i.e., the component securities of the Index, including economic equivalents), and derivatives based on those securities (i.e., the Nasdaq-100 Dividend Futures that are used to construct the Dividend Component). The Fund defines “equity securities” to mean common and preferred stocks, rights, warrants, depositary receipts and ETFs that invest in the equity securities of companies included in the Nasdaq-100 Index. For purposes of this 80% investment policy, (i) the Fund will consider the underlying holdings of any ETFs in which the Fund invests, (ii) the notional value of the futures contracts that make up the Dividend Component, and (iii) the Fund will have some large cap growth investments, some dividend paying large cap investments, and some investments in both of these categories.
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 Calculation Methodology Risk. The Index relies directly or indirectly on various sources of information to assess the criteria of issuers included in the Index, including information that may be based on assumptions and estimates. Neither the Fund, the Index Provider, or the Adviser can offer assurances that the Index’s calculation methodology or sources of information will provide an accurate assessment of included components or a correct valuation of securities, nor can they guarantee the availability or timeliness of the production of the Index.
Pacer Metaurus Nasdaq 100 Dividend Multiplier 600 ETF | Concentration Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
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 Nasdaq 100 Dividend Multiplier 600 ETF | Currency Exchange Rate Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Currency Exchange Rate Risk. The Fund’s assets may include investments denominated in non-U.S. currencies, such as the euro, or in securities or other assets that provide exposure to such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your Fund 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 Metaurus Nasdaq 100 Dividend Multiplier 600 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 Nasdaq 100 Dividend Multiplier 600 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.
Pacer Metaurus Nasdaq 100 Dividend Multiplier 600 ETF | Dividends Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
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. ETF shares can only be redeemed in creation units by APs. Individual shareholders may only purchase and sell ETF shares on a secondary market.
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. Shares of the Fund will be bought and sold in the secondary market at market prices.
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 Metaurus Nasdaq 100 Dividend Multiplier 600 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. Foreign securities held by the Fund may trade on markets that are closed when U.S. markets are open, which may lead to a difference in the value of the Fund and the underlying foreign securities.
Pacer Metaurus Nasdaq 100 Dividend Multiplier 600 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 underlying securities or index 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 settlement price of Nasdaq-100 Dividend Futures or similar futures held by the Fund only reflect unadjusted ordinary dividends declared and paid in the contract period on the individual companies included in the Index. Any special dividends, extraordinary dividends and return of capital payments paid by a company included in the Index will not be reflected in the settlement value of the Nasdaq-100 Dividend Futures or similar futures held by the Fund. 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 Nasdaq-100 Dividend Futures.
Pacer Metaurus Nasdaq 100 Dividend Multiplier 600 ETF | Government Obligations Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
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.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Index Provider Risk. 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 Nasdaq 100 Dividend Multiplier 600 ETF | International Operations Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock International Operations Risk. Investments in companies with significant business operations outside of the United States may involve certain risks that may not be present with investments in U.S. companies. For example, international operations may be subject to risk of loss due to foreign currency fluctuations; changes in foreign political and economic environments, regionally, nationally, and locally; challenges of complying with a wide variety of foreign laws, including corporate governance, operations, taxes, and litigation; differing lending practices; differences in cultures; changes in applicable laws and regulations in the United States that affect international operations; changes in applicable laws and regulations in foreign jurisdictions; difficulties in managing international operations; and obstacles to the repatriation of earnings and cash. These and other factors can make an investment in the Fund more volatile than other types of investments.
Pacer Metaurus Nasdaq 100 Dividend Multiplier 600 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 Nasdaq 100 Dividend Multiplier 600 ETF | New Fund Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock New Fund Risk. The Fund is new with no operating history. As a result, there can be no assurance that the Fund will grow to or maintain an economically viable size, in which case it may experience greater tracking error to its Index than it otherwise would at higher asset levels, or it could ultimately liquidate. The Fund’s distributor does not maintain a secondary market in Fund shares.
Pacer Metaurus Nasdaq 100 Dividend Multiplier 600 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 Nasdaq 100 Dividend Multiplier 600 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 Nasdaq 100 Dividend Multiplier 600 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.
Pacer Metaurus Nasdaq 100 Dividend Multiplier 600 ETF | Tracking Error Risk Member  
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.
Pacer Metaurus Nasdaq 100 Dividend Multiplier 600 ETF | Trading Halt Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
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.

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 and maintained by MSCI Index Metrics (the “Index Provider”).
MSCI World Ricardo Comparative Advantage Select GDP Tilted Index
The Index is a rules-based index that aims to represent the performance of the securities from a set of countries which have the highest active weight in each of the twenty-five GICS® Industry Groups as measured against the MSCI World Index (the “Parent Index”). GICS® Industry Groups comprise one of the four tiers of GICS®, a hierarchical industry classification system maintained by MSCI and S&P Dow Jones Indices. The Index incorporates a gross domestic product (“GDP”) tilt by reweighting the screened securities relative to their corresponding country’s GDP. Securities in the eligible universe of the constituent companies of the Parent Index are screened to identify the country with the highest active country weight in each GICS® Industry Group. Securities with a three-month average daily traded value greater than or equal to $5 million are eligible for inclusion in the Index. The securities that meet the screening criteria are grouped by country and each group is weighted by the product of their aggregated free-float adjusted market capitalization
and the corresponding country’s gross domestic product. Additionally, the constituent security weights are capped at 5% to mitigate concentration risk in the Index. In case it is not feasible to cap the security weights at 5%, the capping will be relaxed to 10% in steps of 1%.
The Index is reconstituted and rebalanced (i.e., companies are added or deleted and weights are reset based on Index rules) on a quarterly basis, coinciding with the February, May, August and November index reviews of the Parent Index.
As of July 31, 2024, the Index was composed of 1,429 constituents. The Index was established in 2024 and is owned and maintained by the Index Provider.
The Fund’s Investment Strategy
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.
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 have significant exposure to companies in the Industrials and Information Technology Sectors. In addition, the Index may have significant exposure to one or more countries at any given time. As of January 10, 2024, the Index had significant exposure to European 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 Currency Exchange Rate Risk. The Fund’s assets may include investments denominated in non-U.S. currencies, such as the euro, or in securities or other assets that provide exposure to such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your Fund 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 MSCI World Industry Advantage 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 MSCI World Industry Advantage ETF | European Investment Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock European Investment Risk. The Fund is more exposed to the economic and political risks of Europe and of the European countries in which it invests than funds whose investments are more geographically diversified. Adverse economic and political events in Europe may cause the Fund’s investments to decline in value. 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 (the “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 risks of investing in the United Kingdom (UK) have been heightened as a result of Brexit, the formal steps taken by the United Kingdom to exit the EU, which has resulted in increased volatility and triggered political, economic, and legal uncertainty. Although the UK has formally left the EU, uncertainty remains as to the long-term consequences of Brexit and issuers in the UK may experience lower growth as a result.
Pacer MSCI World Industry Advantage 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. ETF shares can only be redeemed in creation units by APs. Individual shareholders may only purchase and sell ETF shares on a secondary market.
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 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 Cboe BZX Exchange, 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. Foreign securities held by the Fund may trade on markets that are closed when U.S. markets are open, which may lead to a difference in the value of the Fund and the underlying foreign securities.
Pacer MSCI World Industry Advantage ETF | International Operations Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock International Operations Risk. Investments in companies with significant business operations outside of the United States may involve certain risks that may not be present with investments in U.S. companies. For example, international operations may be subject to risk of loss due to foreign currency fluctuations; changes in foreign political and economic environments, regionally, nationally, and locally; challenges of complying with a wide variety of foreign laws, including corporate governance, operations, taxes, and litigation; differing lending practices; differences in cultures; changes in applicable laws and regulations in the United States that affect international operations; changes in applicable laws and regulations in foreign jurisdictions; difficulties in managing international operations; and obstacles to the repatriation of earnings and cash. These and other factors can make an investment in the Fund more volatile than other types of investments.

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 MSCI World Industry Advantage ETF | New Fund Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock New Fund Risk. The Fund is new with no operating history. As a result, there can be no assurance that the Fund will grow to or maintain an economically viable size, in which case it may experience greater tracking error to its Index than it otherwise would at higher asset levels, or it could ultimately liquidate. The Fund’s distributor does not maintain a secondary market in Fund shares.
Pacer MSCI World Industry Advantage 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 MSCI World Industry Advantage 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.

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.
Industrials Sector Risk. The Fund may invest in companies in the industrials sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. The industrials sector may be affected by changes in the supply of and demand for products and services, product obsolescence, claims for environmental damage or product liability and general economic conditions, among other factors.
Information Technology Sector Risk. The Fund may invest in companies in the information technology sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. Market or economic factors impacting information technology companies and companies that rely heavily on technological advances could have a significant effect on the value of the Fund’s investments. The value of stocks of information technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Stocks of information technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Information
technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability.

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 and maintained by Index Design Group (the “Index Provider” or “IDG”), an affiliate of Pacer Advisors, Inc., the Fund’s investment adviser (the “Adviser”).
The Index
The Index uses a rules-based methodology that seeks to provide exposure to large-capitalization U.S. companies with above average free cash flow margins. Companies with above average free cash flow margins are commonly referred to as “cash cows.”
The initial Index universe is typically derived from the component companies of the Nasdaq-100 Index® (the “Nasdaq-100”). The initial universe of companies is typically screened based on their average projected free cash flows and earnings (if available) over each of the next two fiscal years. Companies for which information on their projected free cash flows or earnings is not available will typically remain in the Index universe. A company’s projected free cash flows and earnings are typically determined by the Index Provider. Companies with negative average projected free cash flows or earnings are typically removed from the Index universe. Additionally, companies in the financial or real estate sectors, real estate investment trusts, special purpose acquisition companies and when-issued securities are typically excluded from the Index universe.
Free Cash Flow (FCF): A company’s cash flow from operations minus capital expenditures.
Sales: The value of what a company sold to its customers during a given period; also known as revenue.
Free Cash Flow Margin: FCF / Sales
The remaining companies are typically ranked by their free cash flow margin (defined as a company's free cash flow divided by sales) for the trailing twelve month period. The equity securities of the 50 companies with the highest free cash flow margin are typically included in the Index. Companies included in the Index are typically weighted by their price momentum score and a company’s price momentum score is typically calculated on each of the reconstitution dates.
The weight of any individual company included in the Index is typically capped at 5%. Weight above the 5% limitation is typically redistributed among the other Index constituents in proportion to their weights. As of July 31, 2024, the companies included in the Index had a market capitalization of $28.1 billion to $3.3 trillion. As of July 31, 2024, the Index had significant exposure to the information technology sector. The Index is typically reconstituted and rebalanced quarterly as of the close of business on the third Friday of February, May, August and November based on data as of the first Friday of the applicable rebalance month
The Nasdaq-100 is designed to measure the performance of 100 of the largest non-financial companies by modified market capitalization listed on the Nasdaq Global Select Market or the Nasdaq Global Market. The Nasdaq-100 generally includes securities issued by U.S. and non-U.S. issuers, including american depositary receipts (“ADRs”), common stocks, ordinary shares and tracking stocks; real estate investment trusts are not eligible for index inclusion.
The Fund’s Investment Strategy
Under normal circumstances, the Fund will seek to invest at least 80% of the Fund’s total assets (exclusive of collateral held from securities lending) in growth securities (i.e., the component securities of 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.
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 have significant exposure to companies in the Information Technology Sector. 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 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. ETF shares can only be redeemed in creation units by APs. Individual shareholders may only purchase and sell ETF shares on a secondary market.
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 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.

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.

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 and maintained by Nasdaq, Inc (the “Index Provider”).
Nasdaq International Patent Leaders Index
The Index is a rules-based full market capitalization-weighted index that consists of companies from the Nasdaq Global Ex United States Large Mid Cap Index with the most valuable patent portfolios.
The Index universe consists of all issuers from the Nasdaq Global Ex United States Large Mid Cap Index. Issuers of all eligible securities are ranked by the patent values as determined by IPR Strategies. IPR Strategies is an independent data provider that seeks to determine the potential value of an issuer by quantifying such issuer’s intangible assets, such as its intellectual property and research and development activities, as represented by patents held by such issuer. To value a company’s patent portfolio, IPR Strategies utilizes a proprietary valuation model that takes into account patent data collected from multiple sources, including patent offices and corporate filings, as well as a variety of other economic data, including actual values from previously traded patents. The model determines a “patent value estimate,” which represents
the estimated dollar value of an issuer’s portfolio of patents. The 100 issuers with the largest patent values as determined by IPR Strategies are selected for inclusion in the Index.
The Index is reconstituted and rebalanced (i.e., companies are added or deleted and weights are reset based on Index rules) semi-annually in June and December.
As of July 18, 2024, the Index was composed of 100 constituents. The Index was established on June 24, 2024 and is owned and maintained by the Index Provider.
The Fund’s Investment Strategy
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.
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 have significant exposure to companies in the Information Technology sectors. In addition, the Index may have significant exposure to one or more countries at any given time. The Index, and consequently the Fund, is expected to have significant exposure to Japanese 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 New Fund Risk. The Fund is new with no operating history. As a result, there can be no assurance that the Fund will grow to or maintain an economically viable size, in which case it may experience greater tracking error to its Index than it otherwise would at higher asset levels, or it could ultimately liquidate. The Fund’s distributor does not maintain a secondary market in Fund shares.

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.
