Book page count calculator
Enter your word count and pick a trim size, font size and spacing. You get an estimated page count as a range, with the working under it, and what that page count means on KDP.
The words per page figure is my estimate, not a KDP figure. It comes from the trim size, KDP's inside margin for that page count and a 0.75 inch margin on the other three sides (my choice, KDP's minimum is lower), then characters per line and lines per page at your font size, with 0.45 of the font size as the average character width and 5.7 characters per word. It then takes off 15% for short last lines and chapter starts, or 30% with many headings or images, and shows a range of 10% either side. Your formatted file decides the real count: Kindlepreneur's survey of authors found about 233 words a page for nonfiction and 280 for fiction, and Reedsy uses 300 for a paperback.
Page limits, margins, spine text and print cost are from KDP's own help pages, checked on 13-Nov-26: print options, trim size, bleed and margins, paperback cover and printing cost. KDP can change them. The print cost is for a black ink paperback in the US store, worked the same way as in the KDP royalty and print cost calculator, which also gives your royalty.
Not included: hardcovers, other trim sizes and stores, and Expanded Distribution.

My estimate, not a KDP figure: 11 pt type, 1.3 line spacing, mostly plain text, no extra pages, KDP inside margin for the page count and 0.75 in on the other three sides, 5.7 characters a word, 15% off for short lines and chapter starts. Your formatted file decides the real count.
Margins: KDP, Set Trim Size, Bleed, and Margins. Checked 14-Nov-26. Same method as the book page count calculator. Charts are made from the same figures as the calculator above. Save the image to keep it.
