Estimates assume standard book fonts (e.g. Garamond, Georgia). Actual page count varies with font choice, paragraph spacing, headers, images, and front/back matter. Use this as a planning guide.

KDP Builder automatically formats your manuscript to the perfect page count for any trim size.

What Affects Your Page Count

Trim Size Matters Most

A 50,000-word novel is ~200 pages at 6"×9" but ~250 pages at 5.5"×8.5". Larger trims fit more words per page, reducing print cost.

Font & Spacing

Going from 11pt to 12pt adds roughly 15% more pages. Increasing line spacing from 1.15 to 1.5 adds ~30%. Both affect readability and cost.

Cost Impact

Every additional page adds $0.012 (B&W) or $0.07 (color) to your printing cost. Optimizing layout can save $0.50–$2.00 per unit.

Frequently Asked Questions

How many words fit on a printed page?+

A standard 6"×9" trade paperback with 11pt font and 1.15 line spacing fits approximately 250–280 words per page. Larger trim sizes (8.5"×11") fit 350–400+ words, while smaller sizes (5"×8") fit 200–230 words. Font size, line spacing, and margins all affect the final count.

What is the ideal page count for a KDP book?+

It depends on the genre. Novels typically run 200–350 pages. Nonfiction guides work well at 120–200 pages. Children’s picture books are 24–36 pages. Low-content books (journals, planners) range from 100–200 pages. KDP requires a minimum of 24 pages and a maximum of 828 pages for paperback.

Does page count affect my printing costs?+

Yes. KDP charges per page for printing, so every page adds to your cost. For black-and-white paperbacks, each page costs $0.012. For color, it is $0.07 per page. Optimizing your page count directly affects your profit margin.

Should I use a larger font to increase page count?+

Artificially inflating page count with oversized fonts looks unprofessional and leads to poor reviews. Instead, choose a font size appropriate for your audience (11–12pt for most books, 14–16pt for large-print editions). Let the content determine the length.
