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 the Fund’s shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the example above, affect the Fund’s performance. During the most recent fiscal year, the Fund’s annual portfolio turnover rate was 0% of the average value of its portfolio. This portfolio turnover rate is calculated without regard to cash instruments or derivatives transactions. If such transactions were included, the Fund’s portfolio turnover rate would be significantly higher.

Strategy [Heading]	rr_StrategyHeading	<span style="color:#000000;font-family:Arial Narrow;font-size:11pt;font-weight:bold;">Principal Investment Strategies</span>
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests in financial instruments that ProShare Advisors believes, in combination, should track the performance of the Index.The Index is designed to measure the performance of three separate contract schedules for West Texas Intermediate (“WTI”) Crude Oil futures. One-third of the index measures the performance of contracts that expire monthly. Each month, this portion of the Index rolls from the current futures contract into the following month’s contract. Another third of the Index measures the performance of futures contracts that expire annually in June. In March, this portion of the Index rolls from the current June futures contract into the following year’s June contract. The remaining third of the Index measures the performance of futures contracts that expire annually in December. In September, this portion of the Index rolls from the current December futures contract into the following year’s December contract. The Index is reset to equal weight in March and September. The Index is constructed and maintained by Bloomberg Index Services Limited. More information about the Index can be found using the Bloomberg ticker symbol “BCBCLI.”In order to maintain its exposure to WTI crude oil futures contracts, the Fund must sell its futures contracts as they near expiration and replace them with new futures contracts with a later expiration date. This is often referred to as “rolling” a futures contract. Futures contracts with a longer term to expiration may be priced higher than futures contracts with a short term to expiration, a relationship called “contango.” When rolling futures contracts that are in contango, the Fund will sell the expiring contract at a relatively lower price and buy a longer-dated contract at a relatively higher price.Conversely, futures contracts with a longer term to expiration may be priced lower than futures contracts with a short term to expiration, a relationship called “backwardation.” When rolling futures contracts that are in backwardation, the Fund will be selling the expiring contract at a relatively higher price and buying a longer-dated contract at a relatively lower price.The weighting (i.e., percentage) of each of the three contract schedules included in the Index fluctuate above or below one-third between the semi-annual reset dates due to changing futures prices and the impact of rolling the futures positions. As a result, the weighting of each contract in the Index will “drift” away from equal weighting. The Index reflects the cost of rolling the futures contracts included in the Index, without regard to income earned on cash positions.Under normal circumstances, the Fund will invest at least 80% of its total assets in components of the Index or in instruments with similar economic characteristics.The Fund will invest principally in the financial instruments listed below.●Derivatives — Financial instruments whose value is derived from the value of an underlying asset or assets, such as stocks, bonds, ETFs, exchange-traded commodity pools, interest rates or indexes. The Fund invests in derivatives in order to gain exposure to the Index. These derivatives principally include:○Futures Contracts — Standardized contracts that obligate the parties to buy or sell an asset at a predetermined price and date in the future.○Swap Agreements — Contracts entered into primarily with major global financial institutions for a specified period ranging from a day to more than one year. In a standard swap transaction, two parties agree to exchange or “swap” payments based on the change in value of an underlying asset or benchmark. For example, two parties may agree to exchange the return (or differentials in rates of returns) earned or realized on a particular investment or instrument.●Exchange-Traded Products (ETPs) — The Fund invests in ETPs or exchange-traded funds (“ETFs”) including registered investment companies and exchange-traded commodity pools. ETPs are types of securities that derive their value from a basket of securities such as stocks, bonds, commodities or indices, and trade intra-day on a national exchange. ETFs are typically open-end investment companies or unit investment trusts whose shares represent an interest in a portfolio of securities. Exchange traded commodity pools are investment vehicles who shares represent an interest in a portfolio of commodities or derivatives whose value is derived from commodities. The Fund may invest in ETPs that are sponsored by an affiliate of the Advisor.●Money Market Instruments — The Fund expects that any cash balances maintained in connection with its use of derivatives will typically be held in high quality, short-term money market instruments, for example:○U.S. Treasury Bills — U.S. government securities that have initial maturities of one year or less, and are supported by the full faith and credit of the U.S. government.○Repurchase Agreements — Contracts in which a seller of securities, usually U.S. government securities or other money market instruments, agrees to buy the securities back at a specified time and price.ProShare Advisors uses a mathematical approach to investing in which it determines the type, quantity and mix of investment positions that it believes, in combination, the Fund should hold to produce returns consistent with its investment objective. The Fund seeks to remain fully invested at all times in financial instruments that, in combination, provide exposure consistent with the investment objective, without regard to market conditions, trends or direction. The Fund may also invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining exposure consistent with the investment objective.The Fund expects to gain exposure by investing a portion of its assets in a wholly-owned subsidiary of the Fund organized under the laws of the Cayman Islands and advised by ProShare Advisors. Because the Fund intends to qualify for treatment as a regulated investment company (“RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended, the Fund intends to invest no more than 25% of the Fund’s total assets in the subsidiary at each quarter end of the Fund’s tax year. Exceeding this amount may have tax consequences, see the section entitled “Tax Risk” in the Fund’s Prospectus for more information. References to investments by the Fund should be read to mean investments by either the Fund or the subsidiary.Please see “Investment Objectives, Principal Investment Strategies and Related Risks” in the Fund’s Prospectus for additional details.●Concentration Risk — The Index and the Fund a significant portion of its value exposed to WTI Crude Oil futures. As a result, the Fund may be subject to greater market fluctuations than a fund that is more broadly invested across industries.

Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Non-Diversification Risk — The Fund has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty.

ProShares K-1 Free Crude Oil Strategy ETF | Investment Strategy Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Investment Strategy Risk — The Fund obtains investment exposure through the use of commodity futures and does not invest directly in physical commodities. The Fund does not invest in nor seek exposure to the current “spot” or cash price of physical crude oil. Crude oil futures contracts typically perform very differently from, and commonly underperform, the spot price of crude oil due to current (and futures expectations of) factors such as storage costs, supply and demand and geopolitical risks. Market conditions and expectations, position limits, collateral requirements, availability of counterparties and other factors may limit the Fund’s ability to achieve the desired exposure to WTI crude oil futures contracts. If the Fund is unable to achieve such exposure it may not be able to meet its investment objective and the Fund’s returns may be different or lower than expected. Additionally, collateral requirements may require the Fund to liquidate its positions, potentially incurring losses and expenses.
ProShares K-1 Free Crude Oil Strategy ETF | Market and Volatility Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Market and Volatility Risk — The value of commodity futures contracts typically is based in great part upon the price movements of a physical commodity and the market’s expectations for such moves in the future. The value of the Fund’s investments – and therefore the value of an investment in the Fund – could decline significantly and without warning, including to zero. Global events such as government interventions, treaties and trading, inter- or intrastate conflict, weather or other natural disasters, changes in supply or production, changes in activity of crude oil commodity producing companies, countries and/or organizations, and changes in speculators’ and/or investor’s demand can cause extreme levels of volatility. Furthermore, since commodities are generally denominated in USD, a strengthening U.S. dollar can also cause significant declines in commodity prices. An active trading market may not exist for certain commodities. Each of these factors and events could have a significant negative impact on the Fund.
ProShares K-1 Free Crude Oil Strategy ETF | Crude Oil Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Risks Specific to the Crude Oil Markets — Several factors may affect the price of crude oil and, in turn, the WTI crude oil futures contracts and other assets, if any, owned by the Fund. These factors include, but are not limited to, significant increases or decreases in the available supply or demand of crude oil, storage costs, technological factors related to new or improved extraction, refining and processing equipment and/or methods, a significant change in the attitude of speculators and investors towards crude oil, large purchases or sales of crude oil by governments or large institutions, other political factors such as new regulations or political discord in oil producing countries, as well as a significant increase or decrease in crude oil hedging activity by crude oil producers. Contemporaneous with the onset of the COVID-19 pandemic in the U.S., crude oil markets experienced shocks to the supply of and demand for crude oil. This led to an oversupply of crude oil, which impacted the price of crude oil and futures contracts on crude oil and caused historic volatility in the market for crude oil and crude oil futures contracts. In April 2020, these market conditions contributed to a period of “extraordinary contango” that resulted in a negative price in the May 2020 WTI crude oil futures contract. If all or a significant portion of the futures contracts held by the Fund at a future date were to reach a negative price, investors in the Fund could lose their entire investment.On February 24, 2022, Russia commenced a military attack on Ukraine. The outbreak of hostilities between the two countries could result in more widespread conflict and could have a severe adverse effect on the region and the markets for securities and commodities, including oil. In addition, sanctions imposed on Russia by the United States and other countries, and any sanctions imposed in the future could have a significant adverse impact on the Russian economy and related markets. The price and liquidity of the futures in which the Fund invests may fluctuate widely as a result of the conflict and related events. How long such conflict and related events will last and whether it will escalate further cannot be predicted. Impacts from the conflict and related events could have significant impact on the Fund’s performance, and the value of an investment in the Fund may decline significantly.
ProShares K-1 Free Crude Oil Strategy ETF | Cost of Futures Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Costs of Futures Investment Risk — When a futures contract is nearing expiration, the Fund will “roll” the futures contract, which means it will generally sell such a contract and use the proceeds to buy a futures contract with a later expiration date. When rolling futures contracts that are in contango, the Fund would sell a lower priced, expiring contract and purchase a higher priced, longer-dated contract. The price difference between the expiring contract and the longer-dated contract may be substantial. Contango in the futures markets may have a significant adverse impact on the performance of the Fund and may cause the WTI crude oil futures contracts to underperform spot oil. Both contango and backwardation may limit or prevent the Fund from achieving its investment objective. Extended periods of contango have occurred in the past and can in the future cause significant losses for the Fund. ProShare Advisors will utilize techniques to seek to (a) mitigate the negative impact of contango or, in certain cases, (b) benefit from the backwardation present in the WTI crude oil futures markets. However, there can be no guarantee that ProShare Advisors will be successful in doing so. There can be no assurance that the Fund’s performance will exceed the performance of a strategy that systematically invests in near month crude oil contracts.
ProShares K-1 Free Crude Oil Strategy ETF | Derivatives Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Derivatives Risk — Investing in derivatives may be considered aggressive and may expose the Fund to greater risks and may result in larger losses or smaller gains than investing directly in the reference asset(s) underlying those derivatives. These risks include counterparty risk, liquidity risk and increased correlation risk. When the Fund uses derivatives, there may be imperfect correlation between the value of the reference asset(s) underlying the derivative (e.g., the WTI crude oil futures market) and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives also may expose the Fund to losses in excess of those amounts initially invested. Any costs associated with using derivatives will also have the effect of lowering the Fund’s return.
ProShares K-1 Free Crude Oil Strategy ETF | Counterparty Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Counterparty Risk — The Fund may lose money if a counterparty does not meet its contractual obligations. While the futures contracts that the Fund will use will be centrally cleared through exchanges that have been designated as “contracts markets” by the Commodity Futures Trading Commission (“CFTC”), the Fund will still be subject to the risk that a counterparty is unable to meet its contractual obligations. For futures contracts these counterparties include both the exchange, which provides a performance guarantee, where the trade is executed, and the futures commission merchant, or brokerage firm, that is a member of the relevant contract market and holds margin on behalf of the Fund. If a counterparty becomes bankrupt or fails to perform its obligations, or if any collateral posted by the counterparty for the benefit of the Fund is insufficient or there are delays in the Fund’s ability to access such collateral, the value of an investment in the Fund may decline. In commodity broker insolvencies, customers have, in fact, been unable to recover from the broker’s estate the full amount of their “customer” funds. The Fund will be subject to credit risk with respect to the amount the Fund expects to receive from counterparties to derivatives and repurchase agreements entered into by the Fund. The Fund may engage in futures transactions with a limited number of counterparties, which may increase the Fund’s exposure to credit risk associated with any single counterparty.Extreme market volatility and economic turbulence in the first part of 2020 led to futures commission merchants increasing margin requirements for certain futures contracts, including nearer-dated WTI crude oil and other oil futures contracts. Some futures commission merchants may impose trading limitations, whether in the form of limits or prohibitions on trading oil futures contracts. If the Fund is subject to increased margin requirements or trading limitations, including exchange position limits, it may not be able to achieve its investment objective.Finally, with respect to the use of swap agreements, if the WTI crude oil futures market has a dramatic intraday move that causes a material decline in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to immediately close out the transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to achieve the desired exposure consistent with the Fund’s investment objective. This, in turn, may prevent the Fund from achieving its investment objective, even if the WTI crude oil futures market reverses all or a portion of its intraday move by the end of the day. As a result, the value of an investment in the Fund may change quickly and without warning.
ProShares K-1 Free Crude Oil Strategy ETF | ETP Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Risks Associated with ETPs — Investing in ETPs generally reflects the risks of owning the underlying instruments it is designed to track. When the Fund invests in ETPs it will indirectly bear its proportionate share of any fees and expenses payable directly by the other investment vehicle. These expenses may be in addition to similar expenses of the Fund that shareholders bear directly.
ProShares K-1 Free Crude Oil Strategy ETF | Subsidiary Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Subsidiary Investment Risk — Changes in the laws of the United States and/or the Cayman Islands, under which the Fund and the Subsidiary are organized, respectively, could result in the inability of the Fund to operate as intended and could negatively affect the Fund and its shareholders.

Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Index Performance Risk — The Index used by the Fund may underperform other asset classes and may underperform other similar indices. The Index is maintained by a third party provider unaffiliated with the Fund or ProShare Advisors. There can be no guarantee that the methodology underlying the Index or the daily calculation of the Index will be free from error.
ProShares K-1 Free Crude Oil Strategy ETF | Market Price Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Market Price Variance Risk — Investors buy and sell Fund shares in the secondary market at market prices. Market prices may be different from the NAV per share of the Fund (i.e., the secondary market price may trade at a price greater than NAV (a premium) or less than NAV (a discount)). The market price of the Fund’s shares will fluctuate in response to changes in the value of the Fund’s holdings, supply and demand for shares and other market factors.
