Who makes it
Create KDP Book is made by the team behind KDP Coloring Book Studio, an AI coloring book generator, and KDP Book Cover Studio, an AI book cover maker. We publish on KDP ourselves, and built these calculators because we needed them.
We are not affiliated with Amazon. Kindle Direct Publishing and KDP are trademarks of Amazon.com, Inc.
Where the KDP numbers come from
Every size, page limit, margin, printing cost and royalty rate on this site comes from KDP's own help pages, which we list on each calculator with the date we checked them. When two KDP pages disagree, we say which one we follow and why. The calculators cover paperbacks sold on Amazon.com in USD.
How we write comparisons
- Every fact about a tool comes from that tool's own public pages, linked under the tool, with the date we read them.
- When a page doesn't say something, we write “Not documented” instead of guessing.
- Our own products are labeled “ours”, described from their public pages like everyone else, and keep their limits in view.
- No tool pays to be listed or ranked, and we don't use affiliate links.
