Know your page count before you format
Word count to pages
Words per page from your trim size, font size, line spacing and margins — not one generic number for every book.
Puzzle & activity books
Puzzles per page, answer key, front matter and one-sided pages for coloring books add up to the exact page count.
Chapters and extras
Chapters on a new or right-hand page, front and back matter and full-page images are counted in, with a page-by-page breakdown.
KDP gutter included
The inside margin grows with the page count (0.375″ up to 150 pages, 0.875″ above 700) — the estimate recalculates until it fits.
KDP limits at a glance
The page range for your trim and paper, pages missing for spine text (80+) and whether a hardcover (76–550 pages) is possible.
Spine and printing cost
Spine width from KDP’s paper thickness, the Amazon.com printing cost and the lowest list price that still earns a royalty.

KDP page count FAQ
How many pages will my book be on KDP?
Divide your word count by the words per page of your layout. In a 6×9 book with 11 pt type, single-and-a-bit (1.15) spacing and 0.75″ margins that is about 320 words per page, so 60,000 words make roughly 200 pages with front matter and chapter openings.
What is the minimum page count on KDP?
A KDP paperback needs at least 24 pages (72 for standard color) and a hardcover 75–550 (KDP’s cover calculator starts at 76). Spine text is allowed only from 80 pages. The calculator tells you how many pages you are missing.
Does the page count have to be even?
Yes — every printed sheet has two sides, so the count is always even. An odd count gets a blank last page; the calculator adds it for you.
How do I count pages for a puzzle book?
Front matter (title, copyright, how to play) + puzzles ÷ puzzles per page + puzzles ÷ solutions per page + back matter. 100 sudoku at one per page with four answers per page and four extra pages make 130 pages.
Why does the gutter change with the page count?
Thicker books curve more at the spine, so KDP asks for a wider inside margin: 0.375″ up to 150 pages, 0.5″ up to 300, 0.625″ up to 500, 0.75″ up to 700 and 0.875″ above. A wider gutter means fewer words per page — the calculator accounts for it.
How accurate is the estimate?
It is close for plain text in a typical serif font; your exact font, headings, dialogue and images move the real count by a few percent. Puzzle book counts are exact. Always check the final PDF in KDP’s previewer.
