- It will be extremely difficult to persuade people to buy a huge and expensive book written by someone they've never heard of.
The maximum number of pages for a book is determined by printing and binding equipment (if the book is printed) and what people are willing to pay, carry and read..
Most printers can produce books with as many as 800 to 1,000 pages, but books with more than 500 pages are unusual. With nonfiction, you need to have enough pages to cover your topic adequately. Don’t skimp, or pad.
- The book should not be so big that it will be priced a lot higher than its competitors or seem like “too much to read.”
- It should not be so short that it seems incomplete, or doesn’t offer value for its cost.
The cost of each additional page printed is insignificant. The cost of each e-page is zero. There is a prejudice against very thin books, so try for a minimum of about 120 pages. Thin books just don’t seem like real books, and the printing on the book’s spine will be tiny.
- With most ebooks, the readers can adjust typeface, type size and vertical/horizontal orientation. That changes the number of apparent pages. A hundred people could read a particular ebook, but they’re not necessarily reading the same book.
