Pages for the chosen interior (B&W · white). Large trims (wider than 6.12″ or taller than 9″) cost more to print.

From KDP’s print rules (checked October 2026): bleed adds 0.125″ to the width and 0.25″ to the height; the gutter grows with the page count (0.375″ up to 150 pages … 0.875″ above 700); other margins at least 0.25″ (0.375″ with bleed). Check the final PDF in KDP’s previewer.

KDP trim size FAQ

What is the most popular KDP trim size?

6 × 9″ for novels and nonfiction; 8.5 × 11″ for puzzle, activity, coloring and workbooks; 8.5 × 8.5″ for children’s books. Large trims (wider than 6.12″ or taller than 9″) cost more to print.

What size should my interior PDF be with bleed?

Trim width + 0.125″ and trim height + 0.25″. A 6 × 9″ book with bleed is 6.125 × 9.25″; an 8.5 × 11″ book is 8.625 × 11.25″. Without bleed the PDF is exactly the trim size.

Do I need bleed for my interior?

Only if images or backgrounds run to the edge of the page. Text-only and puzzle books are usually set up without bleed; the bleed setting applies to the whole interior.

What margins does KDP require?

Inside (gutter): 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. Top, bottom and outside: at least 0.25″ without bleed and 0.375″ with bleed.

Can I use a custom trim size on KDP?

Yes, for paperbacks from 4 to 8.5″ wide and 6 to 11.69″ tall. Custom sizes get fewer distribution options (no Expanded Distribution), so a standard size is usually the better choice.

Which trim sizes are available as hardcover?

KDP hardcovers come in 5.5 × 8.5″, 6 × 9″, 6.14 × 9.21″, 7 × 10″ and 8.25 × 11″, on white, cream or premium color paper.
