The number of pages an ebook should be can vary depending on the topic and the intended audience. However, there are some general guidelines to follow:

• Fiction novels typically range from 50,000 to 100,000 words, which translates to roughly 175 to 350 pages in a traditional print book.
• Non-fiction books can vary widely in length depending on the subject matter. Some non-fiction books may be as short as 30,000 words or as long as 100,000 words.
• Children’s books typically have less number of pages as compare to novels, usually around 20-30 pages.
• An ebook for a specific topic or self-help guide can be as short as 10,000 to 20,000 words, which is around 35 to 70 pages.

It’s important to remember that the most important thing is the quality of the content and not the quantity of the pages. The goal should be to provide readers with valuable information and not to simply fill pages.
