The number of pages is not an indicator of a business plan length and quality. A 20-page plan with dense text and graphics may be as good as a 35-page plan with lots of useful charts, product presentations, business diagrams to illustrate important projections.
The plan is to be measured by its readability and information content. A good business plan should give a reader a good general idea of the project, even if that reader has only 15 minutes to look through the plan. A business plan appearance - its format, headings, spaces in the text and illustrations are all very important for its readability. A summary is also very significant. His main points must submit a business plan short and simple.
Unfortunately, many people still pay attention to the number of pages when evaluating the quality of the business plan. Therefore, some business plans for internal use may be only 5 or 10 pages long. Corporate business plan for a large company can be as long as several hundred pages. A more common version of the plan destined for third-parties usually includes 20-40 pages of text - readable, formatted, illustrated with graphs and brief financial tables.
As a rule, the length of the plan depends on its nature and purpose. Will it include a company and management team description for third-parties? Will it include detailed studies, plans and drafts"? In the end, a business plan form largely depends on its functional purpose.
Venture contests often require a business plan of up to 30 pages, sometimes 40, rarely 50 – provided it includes a detailed description of the investments needed in the plan's appendix. Unfortunately, some contestants try to use dense fonts and to reduce line spacing which, however, does not make their plans any better.
