Word count to pages — pages, spine, print cost and reading time

50,000 words is 167 typeset pages in a 6×9 paperback, and 168 pages once KDP rounds the file up to an even count. The same manuscript gives a 0.3783″ spine (9.61 mm), costs $3.02 to print on Amazon.com and runs 4h10m of silent reading or 5h33m read aloud. Type your own count and all six numbers move together.

Same words, six KDP trims

Page counts for 50,000 words. Each uncalibrated trim borrows the calibrated profile with the smaller page area, so these counts err high rather than low.

Which trim to pick

  • 6 × 9

    Novels and narrative nonfiction. 300 words a page — the default everywhere on this site.

  • 5 × 8

    The mass-market pocket feel. 260 words a page, so the same manuscript runs longer and the spine gets thick enough for text sooner.

  • 8.5 × 11

    Workbooks, journals and activity books. 420 words a page — the fewest pages, the cheapest print.

Trim moves the page count, the spine and the print cost — never the words. Work it back the other way with the book spine width calculator.

The same table, for the word counts people actually search

Six counts cover the range from a lead magnet to a doorstop novel. Each one has its own page with the full breakdown; the table here puts them side by side so you can see what doubling the manuscript does to the spine.

Shade is relative page count, not quality. The ceiling for this ink type is 828 pages, so even 90,000 words at 8.5×11 leaves room.

Reading time is two numbers, not one

Silent reading runs at 200 words a minute, aloud at 150 — the pace a narrator sustains in front of a microphone. So 50,000 words is 4h10m to read and 5h33m to record, and 90,000 words is 7h30m and 10h00m. Use the aloud figure to budget studio time and the silent one to judge whether a reader finishes in one sitting or three.

How the page count is worked out

Pages = words ÷ words per page, rounded up to an even number because KDP pads an odd interior with a blank leaf. Words per page is a calibration: 300 for 6×9 at 11 pt single spacing, 260 for 5×8, 420 for an 8.5×11 workbook, 250 for a Word document at 12 pt double. Chapter openers and dialogue-heavy spreads move a real file by ±5%, so treat the figure as the centre of a range. Printing follows the KDP count: $2.30 flat to 110 pages, then $1.00 plus $0.012 a page.

Questions

Word count questions, answered with numbers

167 pages in a 6×9 paperback at 11 pt single spacing, and 168 pages once KDP rounds the interior file up to an even count. A Word document at 12 pt double spacing runs to 200 pages, a 5×8 paperback to 192 and an 8.5×11 workbook to 120.
