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 for Fund shareholders. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the example, affect the Fund’s performance. During the most recent fiscal year ended December 31, 2024, the Fund’s portfolio turnover rate was 37% of the average value of its portfolio.

Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock
This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
Strategy [Heading] rr_StrategyHeading Investments, Risks, and Performance Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund is a diversified fund that, under normal circumstances, invests at least 80% of its net assets in equity securities of growth companies domiciled, headquartered or whose primary business activities or principal trading markets are in developing countries. A developing country is a country included in the MSCI Emerging Markets (EM) Index and other countries determined by the Adviser to be developing countries based on classifications made by the International Monetary Fund or on country characteristics similar to those of the countries in the EM Index. The Fund may invest up to 20% of its net assets in developed countries and in frontier countries as defined by the MSCI Frontier Markets (FM) Index. The Fund’s investments will be in at least three different countries. The Fund may purchase securities of companies of any market capitalization. The Adviser seeks to invest in businesses it believes have significant opportunities for growth, sustainable competitive advantages, exceptional management, and an attractive valuation.
The Fund’s investments in developing countries generally are traded in currencies other than U.S. dollars, so the Adviser buys and sells foreign currencies to facilitate transactions in portfolio securities. The Adviser usually does not hedge against possible fluctuations in exchange rates, but exposure to a particular currency that the Adviser believes is overvalued may be hedged if the Fund has a substantial position in securities traded in that currency. The Fund may buy and sell currencies for cash at current exchange rates, or using an agreement to purchase or sell a specified currency at a specified future date or within a specified time period, at a price set at the time of the contract.
The investment policy of the Fund relating to the types of securities in which 80% of the Fund’s assets must be invested may be changed by the Fund’s Board of Trustees without shareholder approval upon at least 60 days’ notice.

Baron Emerging Markets Fund | Risk Lose Money [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Fund losses may be incurred due to declines in one or more markets in which Fund investments are made.
Baron Emerging Markets Fund | Non U S Securities [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Non-U.S. Securities. Investing in non-U.S. securities may involve additional risks to those inherent in investing in U.S. securities, including exchange rate fluctuations,
political or economic instability, the imposition of exchange controls, expropriation, limited disclosure and illiquid markets.
Baron Emerging Markets Fund | Developing Countries [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Developing Countries. The Fund invests in developing countries, which include countries in the MSCI Emerging Markets (EM) Index and other countries determined by the Adviser to be developing countries based on classifications made by the International Monetary Fund or on country characteristics similar to those of the countries in the EM Index. Investments in developing countries are subject to all of the risks of non-U.S. investing generally, and have additional heightened risks due to a lack of established legal, political, business and social frameworks to support securities markets, including: delays in settling portfolio securities transactions; currency and capital controls; greater sensitivity to interest rate changes; pervasiveness of corruption and crime; currency exchange rate volatility; and inflation, deflation or currency devaluation.
Baron Emerging Markets Fund | Currency [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Currency. This refers to a decline in the value of a foreign currency versus the U.S. dollar, which reduces the dollar value of securities denominated in that currency. The overall impact on the Fund’s holdings can be significant, unpredictable and long-lasting, depending on the currencies represented in the portfolio and how each one appreciates or depreciates in relation to the U.S. dollar and whether currency positions are hedged. Under normal conditions, the Fund does not engage in extensive foreign currency hedging programs. Further, because exchange rate movements are volatile, the Fund’s attempts at hedging could be unsuccessful, and it may not be possible to effectively hedge the currency risks of many developing countries.
Baron Emerging Markets Fund | Risks Associated with India [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Risks Associated with India. Investing in Indian securities may involve additional risks to those inherent in investing in U.S. securities, including exchange rate fluctuations, political or economic instability, the imposition of exchange controls, expropriation, limited disclosure and illiquid markets. Government actions, bureaucratic obstacles and inconsistent economic reform within the Indian government have had a significant effect on the Indian economy and could adversely affect market conditions, economic growth and the profitability of private enterprises in India. Global factors and foreign actions may inhibit the flow of foreign capital on which India is dependent to sustain its growth. Large portions of many Indian companies remain in the hands of their founders (including members of their families). Corporate governance standards of family-controlled companies may be weaker and less transparent, which increases the potential for loss and unequal treatment of investors. Religious, cultural and military disputes persist in India and between India and Pakistan (as well as sectarian groups within each country).
Baron Emerging Markets Fund | Risks Associated with China and Hong Kong [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Risks Associated with China and Hong Kong. The Chinese government exercises significant control over China’s economy through its industrial policies, monetary policy, management of currency exchange rates, and management of the payment of
foreign currency-denominated obligations. Changes in these policies could adversely impact affected industries or companies in China. China’s economy, particularly its export-oriented industries, may be adversely impacted by trade or political disputes with China’s major trading partners, including the U.S. The United States has imposed tariffs and other trade barriers on Chinese exports, has restricted sales of certain categories of goods to China, and has established barriers to investments in China. Trade disputes may adversely affect the economies of the United States and its trading partners, as well as companies directly or indirectly affected and financial markets generally. The United States government has prohibited U.S. persons from investing in Chinese companies designated as related to the Chinese military. These and possible future restrictions could limit the Fund’s opportunities for investment and require the sale of securities at a loss or make them illiquid. Moreover, the Chinese government is involved in a longstanding dispute with Taiwan that has included threats of invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt unification of Taiwan by force, or if other geopolitical conflicts develop or get worse, economies, markets and individual securities may be severely affected both regionally and globally, and the value of the Fund’s assets may go down. In addition, as its consumer class continues to grow, China’s domestically oriented industries may be especially sensitive to changes in government policy and investment cycles. If China were to exert its authority so as to alter the economic, political or legal structures or the existing social policy of Hong Kong, investor and business confidence in Hong Kong could be negatively affected and have an adverse effect on the Fund’s investments.
Baron Emerging Markets Fund | Risks Associated with Investing in Chinese Companies through Variable Interest Entities [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Risks Associated with Investing in Chinese Companies through Variable Interest Entities. The Fund may obtain exposure to companies based or operated in China by investing through legal structures known as variable interest entities (“VIEs”). Instead of directly owning the equity securities of a Chinese company, a VIE enters into service and other contracts with the Chinese company. Although the VIE has no equity ownership of the Chinese company, the contractual arrangements permit the VIE to consolidate the Chinese company into its financial statements. VIE investments are subject to the risk that any breach of these contractual arrangements will be subject to Chinese law and jurisdiction, that Chinese law may be interpreted or change in a way that affects the enforceability of the VIE’s arrangements, or that contracts between the Chinese company and the VIE may otherwise not be enforceable under Chinese law.
Baron Emerging Markets Fund | Risks of Emphasizing a Region Country Sector or Industry [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Risks of Emphasizing a Region, Country, Sector or Industry. If the Fund has invested a higher percentage of its total assets in a particular region, country, sector or industry, changes affecting that region, country, sector or industry may have a significant impact on the performance of the Fund’s overall portfolio.
Baron Emerging Markets Fund | Frontier Countries [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Frontier Countries. The Fund’s investments in frontier countries, which include countries in the MSCI Frontier Markets (FM) Index, are subject to all of the risks of non-U.S. investing generally and the risks of investing in developing countries, except that such risks are greater in frontier countries.
Baron Emerging Markets Fund | Growth Investing [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Growth Investing. Growth stocks can react differently to issuer, political, market and economic developments than the market as a whole and other types of stocks. Growth stocks tend to be more expensive relative to their earnings or assets compared to other types of stocks. As a result, because growth stocks tend to be sensitive to changes in their earnings and to increasing interest rates and inflation, they tend to be more volatile than other types of stocks. In response, from time to time, growth investing as an investment style may go out of favor with investors.
Baron Emerging Markets Fund | General Stock Market [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
General Stock Market. Fund losses may be incurred due to declines in one or more markets in which Fund investments are made. These declines may be the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s). In addition, turbulence as has recently been experienced, caused, among other reasons, by increased inflation, tightening monetary policy and interest rate increases by the US Federal Reserve or similar international bodies, and reduced liquidity in financial markets may continue to negatively affect many issuers, which could have an adverse effect on your Fund investment. Events involving limited liquidity, defaults, non-performance or other adverse developments that affect one industry, such as the financial services industry, or concerns or rumors about any events of these kinds, have in the past and may in the future lead to market-wide liquidity problems, may spread to other industries, and could negatively affect the value and liquidity of the Fund’s investments. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market, such as Russia’s invasion of Ukraine in February 2022 and the world-wide response to it, have and may continue to adversely impact issuers and markets worldwide. Increasingly strained relations between countries, including between the U.S. and traditional allies and/or adversaries, could adversely affect U.S. issuers as well as non-U.S. issuers that rely on the United States for trade. A fund’s securities may be negatively impacted by inflation (or expectations for inflation), interest rates, global demand for particular products/services or resources, supply chain disruptions, natural disasters, pandemics, epidemics, terrorism, war, military confrontations, changes in trade regulations, elevated levels of government debt, internal unrest and discord, economic sanctions, regulatory events and governmental or quasi-governmental actions, among others. The active and expanding conflict in the Middle East between Israel and Hamas presents considerable market risks. Raising the ceiling on U.S. government debt has become increasingly politicized. Any failure to increase the total amount that the U.S. government is authorized to borrow could lead to a default on U.S. government
obligations, with unpredictable consequences for economies and markets in the U.S. and elsewhere.
Baron Emerging Markets Fund | Information Technology Sectors [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Information Technology Sector. Companies in the information technology sector are subject to rapid changes in technology product cycles; rapid product obsolescence; government regulation; and increased competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Information technology companies and companies that rely heavily on technology tend to be more volatile than the overall market and also are heavily dependent on patent and intellectual property rights. In addition, information technology companies may have limited product lines, markets, financial resources or personnel.
Baron Emerging Markets Fund | Consumer Discretionary Sectors [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Consumer Discretionary Sector. The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, inflation, competition, consumers’ disposable income, consumer preferences, social trends and marketing campaigns.
Baron Emerging Markets Fund | Industrials Sector [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Industrials Sector. The Fund’s investments are exposed to issuers conducting business in the Industrials Sector. The Industrials Sector includes manufacturers and distributors of capital goods such as aerospace and defense, building projects, electrical equipment and machinery and companies that offer construction and engineering services. It also includes providers of commercial and professional services including printing, environmental and facilities services, office services and supplies, security and alarm services, human resource and employment services, research and consulting services. It also includes companies that provide transportation services. The Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the Industrials Sector. The prices of the securities of companies operating in the Industrials Sector may fluctuate due to the level and volatility of commodity prices, the exchange value of the dollar, import controls, worldwide competition, liability for environmental damage, depletion of resources, and mandated expenditures for safety and pollution control devices.
Baron Emerging Markets Fund | Small and Mid Sized Companies [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Small- and Mid-Sized Companies. The Adviser believes there is more potential for capital appreciation in small- and mid-sized companies, but there also may be more risk. Securities of small- and mid-sized companies may not be well known to most investors, and the securities may be less actively traded than those of large businesses. The securities of small- and mid-sized companies may fluctuate in price more widely than the stock market generally, and they may be more difficult to sell during market downturns. Small- and mid-sized companies rely more on the skills of management and on their continued tenure. Investing in small- and mid-sized
companies requires a long-term outlook and may require shareholders to assume more risk and to have more patience than investing in the securities of larger, more established companies.
