In today’s world, it’s a great time to be a writer! All you need is a great idea, not a lot of words. There’s no requirement to the length for books, such as one that will appear on the Kindle app and Kindle devices. A huge number of Kindle ebooks that Amazon sells are relatively short but command full price.
If you publish a short ebook, like one that is only 50 to 100 pages long (Kindle “screens”), then your book might be too short for a paperback edition. However, a short book is fine to sell as an ebook. If the content is powerful, you shouldn’t hesitate to sell your book for as much as any other comparable title. We’ll encourage you to price your books based on content, not length.
