The length of a grant proposal can vary depending on the specific guidelines provided by the funding organization. It is important to carefully review the application instructions or guidelines to determine the preferred length. In general, grant proposals can range from a few pages to several dozen pages. However, most funders specify a preferred page limit. Commonly, grant proposals may be around 10 to 20 pages, excluding supporting documents such as budgets, appendices, or letters of support. It's essential to follow the funder's guidelines regarding page limits and formatting requirements.
