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 produce daily returns consistent with the Daily Target.The Index is designed to measure the performance of the large and mid-cap segments of the Japanese market. The Index seeks to include 85% of the market capitalization in Japan and selects companies based on their market capitalization and liquidity. These companies are then weighted based on market capitalization. The Index’s composition and assigned weights are reevaluated semi-annually in May and November with a more limited reevaluation occurring in February and August. The Index is constructed and maintained by MSCI Inc. More information about the Index can be found using the Bloomberg ticker symbol “MXJP.”Under normal circumstances, the Fund will obtain leveraged exposure to 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.●Equity Securities — Common stock issued by public companies.●Exchange-Traded Funds — Registered investment companies that are traded on stock exchanges and hold assets such as stocks or bonds.●Derivatives — Financial instruments whose value is derived from the value of an underlying asset or rate, such as stocks, bonds, ETFs, interest rates or indexes. 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.●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.●Depositary Receipts — The Fund may invest in depositary receipts, which principally include:○American Depositary Receipts (ADRs), which represent the right to receive securities of foreign issuers deposited in a bank or trust company and are an alternative to purchasing the underlying securities in their national markets and currencies.○Global Depositary Receipts (GDRs), which are receipts for shares in a foreign-based corporation traded in capital markets around the world.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 daily returns consistent with the Daily Target. For these purposes a day is measured from the time of one net asset value (“NAV”) calculation to the next.The Fund seeks to remain fully invested at all times in financial instruments that, in combination, provide leveraged exposure consistent with the investment objective, without regard to market conditions, trends or direction. However, the Fund may 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 leveraged exposure consistent with the investment objective.The Fund seeks to rebalance its portfolio each day so that its exposure to the Index is consistent with the Daily Target. The Index’s movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should rise (assuming there were no Creation Unit redemptions). As a result, the Fund’s exposure will need to be increased. Conversely, if the Index has fallen on a given day, net assets of the Fund should fall (assuming there were no Creation Units issued). As a result, the Fund’s exposure will need to be decreased.Please see “Investment Objectives, Principal Investment Strategies and Related Risks” in the Fund’s Prospectus for additional details.

ProShares Ultra MSCI Japan | 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.

Risk [Text Block]	rr_RiskTextBlock	You could lose money by investing in the Fund.
ProShares Ultra MSCI Japan | Leverage Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Leverage Risk — The Fund uses leverage and will lose more money when the value of the Index falls than a similar fund that does not use leverage. The use of leverage increases the risk of a total loss of your investment. If the Index approaches a 50% loss at any point in the day, you could lose your entire investment. As a result, an investment in the Fund may not be suitable for all investors. The use of leverage increases the volatility of your returns. The cost of obtaining this leverage will lower your returns.
ProShares Ultra MSCI Japan | Holding Period Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Holding Period Risk — The performance of the Fund for periods longer than a single day will likely differ from the Daily Target. This difference may be significant. If you are considering holding fund shares for longer than a day, it’s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund’s returns as much as or more than the return of the Index.The following table illustrates the impact of Index volatility and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.In the table areas shaded darker represent those scenarios where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index rises.The table uses hypothetical annualized Index volatility and Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -40% return on a yearly basis if the annual Index return were -20%. However, as the table shows, with a one-year Index return of -20% and an annualized Index volatility of 50%, the Fund could be expected to return -50.2%.Estimated Fund ReturnsIndex PerformanceOne Year Volatility RateOneYearIndexTwo times(2x) theOne YearIndex10%25%50%75%100%-60%-120%-84.2%-85.0%-87.5%-90.9%-94.1%-50%-100%-75.2%-76.5%-80.5%-85.8%-90.8%-40%-80%-64.4%-66.2%-72.0%-79.5%-86.8%-30%-60%-51.5%-54.0%-61.8%-72.1%-82.0%-20%-40%-36.6%-39.9%-50.2%-63.5%-76.5%-10%-20%-19.8%-23.9%-36.9%-53.8%-70.2%0%0%-1.0%-6.1%-22.1%-43.0%-63.2%10%20%19.8%13.7%-5.8%-31.1%-55.5%20%40%42.6%35.3%12.1%-18.0%-47.0%30%60%67.3%58.8%31.6%-3.7%-37.8%40%80%94.0%84.1%52.6%11.7%-27.9%50%100%122.8%111.4%75.2%28.2%-17.2%60%120%153.5%140.5%99.4%45.9%-5.8%Assumes: (a) no dividends paid with respect to securities included in the Index; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain leveraged exposure) of zero percent. If these were included the Fund’s performance would be different from that shown.The Index’s annualized historical volatility rate for the five-year period ended May 31, 2024 was 17.76%. The Index’s highest May to May volatility rate during the five-year period was 19.57% (May 29, 2020). The Index’s annualized total return performance for the five-year period ended May 31, 2024 was 7.55%. Historical Index volatility and performance do not predict future Index volatility and performance.For more information, including additional graphs and charts demonstrating the effects of Index volatility and Index return on the long-term performance of the Fund, see “Understanding the Risks and Long-Term Performance of a Daily Objective Fund” in the Fund’s Prospectus.
ProShares Ultra MSCI Japan | 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 leveraged correlation with the Index. Fees, expenses, transaction costs, financing costs associated with the use of derivatives, among other factors, will adversely impact the Fund’s ability to meet its Daily Target. In addition, the Fund may not have leveraged 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. Moreover, if for any reason the Fund is unable to rebalance all or a portion of its investments, the Fund may have exposure to the Index that is significantly greater or less than the Daily Target. Any of these factors may prevent the Fund from achieving exposure consistent with the Daily Target. Also, the Fund will measure its correlation to the performance of one or more ETFs. It is important to note that correlation to these ETFs may vary from the correlation to the Index due to embedded costs and other factors.
ProShares Ultra MSCI Japan | Derivatives Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Derivatives Risk — Investing in derivatives to obtain leveraged 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. To the extent the Fund invests in swaps that use an ETF as the reference asset, the Fund will be subject to the risks of that ETF including the risk that the ETF may not meet its investment objective. In addition, the Fund may be subject to greater correlation risk since the performance of the ETF may not correlate to the performance of the Index. Any costs associated with using derivatives will reduce the Fund’s return.
ProShares Ultra MSCI Japan | 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 Ultra MSCI Japan | Japanese Investment Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Exposure to Japanese Investments Risk — Investments in Japan are subject to risks including, but not limited to (i) political, economic, or social instability in Japan; (ii) risks associated with Japan’s large government deficit; (iii) natural disasters particularly likely to occur in Japan; (iv) risks associated with an increasingly aging and declining population that is likely to strain Japan’s social welfare and pension systems; and (v) relatively high unemployment. Since the year 2000, Japan’s economic growth rate has remained relatively low. As an island nation, Japan has limited natural resources and land area, and the Japanese economy is heavily dependent on international trade and reliant on imports for its commodity needs. Fluctuations or shortages in the commodity markets may negatively impact the Japanese economy. Slowdowns in the U.S. and/or China and other Southeast Asian countries, including economic, political or social instability in such countries, could have a negative impact on Japan. Because of its trade dependence, the Japanese economy is particularly exposed to the risks of currency fluctuation, foreign trade policy and regional and global economic disruption, including the risk of increased tariffs, embargoes, and other trade limitations. Strained relationships between Japan and its neighboring countries, including China, South Korea and North Korea, based on historical grievances, territorial disputes, and defense concerns, may also inject uncertainty into Japanese markets. As a result, additional tariffs, other trade barriers, or boycotts may have an adverse impact on the Japanese economy.
ProShares Ultra MSCI Japan | Equity Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Equity and Market Risk — Equity markets are volatile, and the value of equity securities and other instruments correlated with equity markets may fluctuate dramatically from day to day. Equity markets are subject to corporate, political, regulatory, market and economic developments, as well as developments that impact specific economic sectors, industries or segments of the market.
ProShares Ultra MSCI Japan | ETF Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Risk of Investing in Exchange-Traded Funds (ETFs) – Investing in other investment companies, such as ETFs, subjects the Fund to those risks affecting the underlying ETFs, such as risks that the investment management strategy of the ETF may not produce its intended results (management risk) and the risk that the ETF could lose money over short periods due to short-term market movements and over longer periods during market downturns (market risk). In addition, investing in ETFs involves the risk that an ETF’s performance may not track the performance of the index or markets that the ETF is designed to track, which may result in losses to such ETF and, ultimately, the Fund. In addition, ETFs may trade at a price below their net asset value. Moreover, the Fund will incur its share of the expenses of the underlying ETF’s expenses.
ProShares Ultra MSCI Japan | Foreign Currency Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Exposure to Foreign Currency Risk — Investments linked to or denominated in foreign currencies are exposed to additional risk factors versus those investments denominated in U.S. dollars and linked to U.S. investments. The value of an investment linked to or denominated in a foreign currency could change significantly as foreign currencies strengthen or weaken relative to the U.S. dollar.
ProShares Ultra MSCI Japan | Foreign-EM Markets Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Exposure to Foreign Investments Risk — Exposure to securities of foreign issuers may provide the Fund with increased risk. Foreign investments may be more susceptible to political, social, economic and regional factors than may be the case with U.S. securities. In addition, markets for foreign investments are usually less liquid, more volatile and significantly smaller than markets for U.S. securities, which may affect, among other things, the Fund’s ability to purchase or sell foreign investments at appropriate times and prices. Because of differences in settlement times and/or foreign market holidays, transactions in a foreign market may take place one or more days after the necessary exposure to these investments is determined.

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 Ultra MSCI Japan | Concentration-Focus Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	●Industry Concentration Risk — The Index may have a significant portion of its value in issuers in an industry or group of industries. The Fund will allocate its investments to approximately the same extent as the Index. As a result, the Fund may be subject to greater market fluctuations than a fund that is more broadly invested across industries. As of May 31, 2024, the Index had a significant portion of its value in issuers in the consumer discretionary, industrials and information technology industry groups.

[1] “Acquired Fund Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies (such as exchange-traded funds). They are not direct costs paid by Fund shareholders and are not used to calculate the Fund’s net asset value (“NAV”). “Acquired Fund Fees and Expenses” are not directly borne by the Fund and are not reflected in the Fund’s Financial Statements in the annual report. Therefore, the amounts listed in “Total Annual Fund Operating Expenses” will differ from those presented in the Fund’s Financial Highlights in the Fund’s Prospectus.

[2] ProShare Advisors LLC (“ProShare Advisors”) has agreed to waive fees and to reimburse expenses (excluding Acquired Fund Fees and Expenses) to the extent Total Annual Fund Operating Expenses Before Fee Waivers and Expense Reimbursements, as a percentage of average daily net assets, exceed 0.95% through September 30, 2025. Amounts waived or reimbursed in a particular contractual period may be recouped by ProShare Advisors within five years subject to certain limitations.

[3] Reflects no deduction for fees, expenses or taxes. Returns are net returns that are adjusted to reflect the reduction of any withholding taxes and the reinvestment of dividends paid by companies in the Index.
