Investment Risks - VALUE LINE LARGER COMPANIES FOCUSED FUND, INC.	Apr. 30, 2025
Risk Lose Money [Member]
Prospectus [Line Items]
Risk [Text Block]	Investing in any mutual fund involves risk, including the risk that you may receive little or no return on your investment, and that you may lose money.
Risk Not Insured [Member]
Prospectus [Line Items]
Risk [Text Block]	An investment in the Fund is not a complete investment program and you should consider it just one part of your total investment program. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency.
Growth Style Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Growth Style Risk. Growth stocks may be more volatile than other stocks because they are generally more sensitive to investor perceptions and market movements. In addition, growth stocks as a group may be out of favor at times and underperform the overall equity market for long periods while investors concentrate on other types of stocks, such as “value” stocks.
Market Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Market Risk. The chief risk that you assume when investing in the Fund is market risk which is the possibility that the securities in a certain market will decline in value because of factors such as recessions, changes in interest rates, global trade policies, war, terrorism including cyber terrorism, natural and environmental disasters as well as public health emergencies. Market risk may have a material impact on a single issuer, an industry, a sector of the economy or the market as a whole and could be significant and cause losses.
Equity Securities Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Equity Securities Risk. Equity securities represent ownership in a corporation and their prices fluctuate for a number of reasons including issuer-specific events, market perceptions and general movements in the equity markets. The resulting fluctuation in the price of equity securities may take the form of a drastic movement or a sustained trend. If an issuer is liquidated or declares bankruptcy, the claims of owners of bonds will take precedence over the claims of owners of common stocks. Historically, the prices of equity securities have fluctuated more than bond prices.
Liquidity Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Liquidity Risk. Certain securities may be difficult or impossible to sell at the time and price that the Fund would like when there is little or no active trading market. If a security cannot be sold by the Fund at a favorable time and price, the Fund may have to lower the price, sell other securities instead, or forgo an investment opportunity in order to obtain liquidity. This could have a negative effect on the Fund’s performance.
Sector Allocation Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Sector Allocation Risk. A sector is a group of selected industries within the economy, such as technology. The Fund may be overweighted or underweighted in certain sectors, which may cause the Fund’s performance to be more or less sensitive, respectively, to developments affecting those sectors.
Focused Portfolio Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Focused Portfolio Risk. Because the Fund may invest a significant portion of its assets in a small number of securities, the Fund’s net asset value may be more volatile and the Fund’s investments may involve more risk than investing in a fund that holds a greater number of securities.
Small and Mid-Sized Company Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Small and Mid-Sized Company Risk. Investments in small and mid-sized companies may involve greater risks than investments in larger, more established companies — as a general rule, the smaller the market capitalization of the company, the greater the risk. As compared to larger companies, small and mid-sized companies may have limited management experience or depth, limited ability to generate or borrow capital needed for growth, and limited products or services, or may operate in less established markets. Accordingly, small and mid-sized company securities may be more sensitive to changing economic, market, and industry conditions and may be more volatile and less liquid than equity securities of larger companies, especially over the short term. Small and mid-sized companies also may fall out of favor relative to larger companies in certain market cycles, causing the Fund to incur losses or underperform.
Ranking System Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Ranking System Risk. The Adviser’s use of the results of the Ranking System in managing the Fund involves the risk that the Ranking System may not have the predictive qualities anticipated by the Adviser or that over certain periods of time the price of securities not covered by the Ranking System, or lower-ranked securities, may appreciate to a greater extent than those securities in the Fund’s portfolio. Quantitative models like the Ranking Systems may not work as anticipated, potentially resulting in lower investment performance or losses to the Fund.
Active Management Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Active Management Risk. Because the Fund is actively managed, its investment return depends on the ability of the Adviser to manage its portfolio successfully. There can be no guarantee that the Adviser’s investment strategies will produce the desired results or that the investment objective of the Fund will be achieved.
Foreign Investments Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Foreign Investments Risk. Investing in foreign securities poses additional risks. The performance of foreign securities can be adversely affected by the different political, regulatory and economic environments in countries where the Fund invests, and fluctuations in foreign currency exchange rates may also adversely affect the value of foreign securities. These risks tend to be more volatile in emerging markets (as compared to the U.S. market or developed foreign markets).
Market Disruption Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Market Disruption Risk. Markets may be impacted by negative external and /or direct and indirect economic factors such as pandemics (including COVID-19), natural disasters, global trade policies and political unrest or uncertainties. The adverse impact of any one or more of these events on the market value of Fund investments could be significant and can affect the economies of many nations, individual companies and the market in general. The Adviser cannot predict the likelihood of occurrence or the effects of similar disruptive events in the future on the U.S. and other economies, or the investments in the Fund’s portfolio or the potential for success of the Fund.
Cybersecurity Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Cybersecurity Risk. As the use of technology becomes more prevalent in the course of business, the Fund becomes more susceptible to operational, financial and information security risks resulting from cyberattacks and/or technological malfunctions. Successful cyberattacks and/or technological malfunctions affecting the Fund or its service providers can result in, among other things, financial losses to the Fund and its shareholders, the inability to process transactions with shareholders or other parties and the release of private shareholder information or confidential Fund information. While measures have been developed which are designed to reduce the risks associated with cybersecurity, there are inherent limitations in such measures and there is no guarantee those measures will be effective, particularly since the Fund does not directly control the cybersecurity measures of its service providers, financial intermediaries or companies in which it invests or with which it does business.
