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 the Break-Even Rate of Inflation (“BEI”), or the difference in yield between a U.S. Treasury bond and a U.S. Treasury Inflation-Protected Securities (“TIPS”). The Index measures the performance of three positions: (1) a long position in the most recently issued 30-year TIPS; (2) a duration-matched short position in U.S. Treasury bonds; and (3) a cash equivalent security that represents the interest earned on the short position. The Index’s positions are reset each month. The Index is constructed and maintained by FTSE International Limited. More information about the Index can be found using the Bloomberg ticker symbol “CFIIRINF.”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.●U.S. Treasury Securities — The Fund has exposure to securities issued by the U.S. Treasury, in particular the following:○U.S. Treasury Inflation-Protected Securities — The Fund generally takes long positions (or obtains long exposure via derivatives, as further described below) in TIPS, which are inflation-protected public obligations of the U.S. Treasury. TIPS are income-generating instruments whose interest and principal payments are adjusted for inflation — a sustained increase in prices that erodes the purchasing power of money. The inflation adjustment, which is typically applied monthly to the principal of the bond, follows a designated inflation index, such as the consumer price index. A fixed coupon rate is applied to the inflation-adjusted principal so that as inflation rises, the values of both the principal and the interest payments increase. This can provide investors with a hedge against inflation, as it helps preserve the purchasing power of an investment. Because of this inflation adjustment feature, inflation-protected bonds typically have lower yields than conventional fixed-rate bonds.●Derivatives — Financial instruments whose value is derived from the value of an underlying asset or assets, such as stocks, bonds, ETFs, interest rates or indexes. The Fund invests in derivatives in order to gain exposure to the Index. These derivatives principally include:○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.○Futures Contracts — Standardized contracts that obligate the parties to buy or sell an asset at a predetermined price and date in the future.●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.Please see “Investment Objectives, Principal Investment Strategies and Related Risks” in the Fund’s Prospectus for additional details.

Risk [Text Block]	rr_RiskTextBlock	The Fund seeks to mitigate this risk by taking short positions in U.S. Treasury Securities; such short positions should increase in value in rising interest rate environments and should decrease in value in falling interest rate environments. The Fund does not attempt to mitigate credit risk or other factors which may have a greater influence on its investments than interest rate risk.

ProShares Inflation Expectations | Risk Nondiversified Status [Member]
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 Inflation Expectations | Breakeven Inflation Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Breakeven Inflation Investing Risk — The Index tracks the performance of (i) long positions in the most recently issued 30-year TIPS and (ii) duration-adjusted short positions in U.S. Treasury bonds of, in aggregate, approximate equivalent duration dollars to the TIPS. The Index seeks to achieve an overall duration dollar amount of zero. The difference in yield (or spread) between these bonds (Treasury yield minus TIPS yield) is commonly referred to as a BEI and is considered to be a measure of the market’s expectations for inflation over the relevant period. The level of the Index (and the Fund) will fluctuate based on changes in the value of the underlying bonds, which will likely not be the same on a percentage basis as changes in the BEI. The Index is not designed to measure or predict the realized rate of inflation, nor does it seek to replicate the returns of any price index or measure of actual consumer price levels. Changes in the BEI are based on the TIPS and U.S. Treasury markets, interest rate and inflation expectations, and fiscal and monetary policy.There is no guarantee that these factors will combine to produce any particular directional changes in the Index over time, or that the Fund will retain any appreciation in value over extended periods of time, or that the returns of the Index or the Fund will track or outpace the realized rate of inflation, or any price index or measure of actual consumer price levels. It is possible that the returns of the Index or the Fund will not correlate to (or may be the opposite of) the change in the realized rate of inflation, or any price index, or measure of actual consumer price levels. Furthermore, while the BEI provides exposure to inflation expectations, it may also be influenced by other factors, including premiums related to liquidity for certain bonds as well as premiums surrounding the uncertainty of future inflation. These other factors may impact the level of the Index or the value of the Fund in unexpected ways and may cancel out or even reverse the impact of changes in inflation expectations. As a result, an investment in the Fund may not serve as an effective hedge against inflation.
ProShares Inflation Expectations | Hedging Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Hedging Risk — The Index seeks to mitigate the potential negative impact of rising Treasury interest rates on the performance of TIPS. The short positions in U.S. Treasury Securities are not intended to mitigate inflation risk or other factors influencing the BEI, which may have a greater impact than rising or falling interest rates. There is no guarantee that the short positions will completely eliminate the interest rate risk of the TIPS positions. The hedge cannot fully account for changes in the shape of the Treasury interest rate (yield) curve. Because the duration hedge is reset on a monthly basis, interest rate risk can develop intra-month. When interest rates fall, an unhedged investment in the same TIPS will outperform the Fund. The performance of the Fund could be particularly poor if the BEI deteriorates at the same time Treasury interest rates fall. Furthermore, when interest rates remain unchanged, an investment in the Fund will underperform a long-only investment in the same TIPS due to the ongoing costs associated with short exposure to Treasury securities.
ProShares Inflation Expectations | Derivatives Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Derivatives Risk — Investing in derivatives to obtain exposure may be considered aggressive and may expose the Fund to greater risks including counterparty risk and correlation risk. The Fund may lose money if its derivatives do not perform as expected and may even lose money if they do perform as expected. Any costs associated with using derivatives will reduce the Fund’s return.
ProShares Inflation Expectations | 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. With respect to swap agreements, if the Index 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 its investment objective.
ProShares Inflation Expectations | Debt Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Debt Instrument Risk — Debt instruments are subject to adverse issuer, political, regulatory, market and economic developments, as well as developments that affect specific economic sectors, industries or segments of the market. Debt markets can be volatile and the value of instruments correlated with these markets may fluctuate dramatically from day to day.
ProShares Inflation Expectations | Inflation-Indexed Security Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Inflation-Indexed Security Risk — The value of an inflation-indexed security (such as TIPS) tends to decrease when real interest rates increase, and tend to increase when real interest rates decrease. Real interest rates are generally measured as a nominal interest rate less an inflation rate.
ProShares Inflation Expectations | US Treasury Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●U.S. Treasury Market Risk — The U.S. Treasury market can be volatile, and the value of instruments correlated with these markets may fluctuate dramatically from day to day. U.S. Treasury obligations may provide relatively lower returns than those of other securities. Similar to other debt instruments, U.S. Treasury obligations are subject to debt instrument risk and interest rate risk. In addition, changes to the financial condition or credit rating of the U.S. Government may cause the value of U.S. Treasury obligations to decline.
ProShares Inflation Expectations | Interest Rate Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Interest Rate Risk — Interest rate risk is the risk that debt instruments or related financial instruments may fluctuate in value due to changes in interest rates. A wide variety of factors can cause interest rates to fluctuate (e.g., central bank monetary policies, inflation rates, general economic conditions, etc.). Commonly, investments subject to interest rate risk will decrease in value when interest rates rise and increase in value when interest rates decline. A rising interest rate environment may cause the value of debt instruments to decrease and adversely impact the liquidity of debt instruments. Without taking into account other factors, the value of securities with longer maturities typically fluctuates more in response to interest rate changes than securities with shorter maturities. These factors may cause the value of an investment in the Fund to change.
ProShares Inflation Expectations | Prepayment Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Prepayment Risk — Many types of debt instruments are subject to prepayment risk, which is the risk that the issuer of the security will repay principal (in part or in whole) prior to the maturity date. Debt instruments allowing prepayment may offer less potential for gains during a period of declining interest rates, as the proceeds may be reinvested at lower interest rates.
ProShares Inflation Expectations | Money Market Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Money Market Instruments Risk — Adverse economic, political or market events affecting issuers of money market instruments, defaults by counterparties or changes in government regulations may have a negative impact on the performance of the Fund.
ProShares Inflation Expectations | Long-Short Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Long/Short Risk — The Fund seeks long exposure to certain financial instruments and short exposure to certain other financial instruments. There is no guarantee that the returns on the Fund’s long or short positions will produce positive returns and the Fund could lose money if either or both the Fund’s long and short positions produce negative returns. Seeking short exposure may be considered an investment aggressive technique. Any income, dividends, or payments by the assets underlying the Fund’s short positions will negatively impact the Fund.In addition, the Fund may gain enhanced long exposure to certain financial instruments (i.e., obtain investment exposure that exceeds the amount directly invested in those assets, a form of leverage) and, under such circumstances, will lose more money in market environments that are adverse to its long positions than funds that do not employ such leverage. The use of leverage increases the volatility of your returns. The cost of obtaining this leverage will lower your returns.
ProShares Inflation Expectations | Correlation Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Correlation Risk — A number of factors may affect the Fund’s ability to achieve a high degree of correlation with the Index. Fees, expenses, transaction costs, among other factors, will adversely impact the Fund’s ability to meet its investment objective. In addition, the Fund’s exposure may not be consistent with the Index. For example, the Fund may not have exposure to all of the securities in the Index, its weighting of securities may be different from that of the Index, and it may invest in instruments not included in the Index.
ProShares Inflation Expectations | Index Performance Risk [Member]
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 Inflation Expectations | 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.
ProShares Inflation Expectations | Early Close Late Close Trading Halt Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Early Close/Late Close/Trading Halt Risk — An exchange or market may close early, close late or issue trading halts on specific securities or financial instruments. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.
