A hardcover spine adds 4.8 mm to the paper thickness, so even at 76 pages it is wide enough for 7 pt text inside 0.0625 in spine margins. KDP's hardcover cover guide gives no minimum page count for spine text, and kdpbook allows it on every hardcover.

## Questions

Q: How many pages can an 8.25 × 11 in book have on KDP?
A: It isn't offered as a paperback. As a hardcover: 75–550 pages in black and white on white paper, black and white on cream paper or premium color. KDP counts every page, blank ones included, and rounds an odd count up to the next even number.

Q: What cover size does an 8.25 × 11 in book need on KDP?
A: It depends on the page count and the paper. A 120-page 8.25 × 11 in hardcover in black and white on white paper needs a cover file of 18.534 × 12.417 in (470.8 × 315.4 mm), because the art wraps around boards larger than the trim.

Q: Can an 8.25 × 11 in book be a paperback on KDP?
A: Not as a standard size: 8.25 × 11 in is hardcover only on KDP. The closest standard paperback is 8.5 × 11 in. KDP accepts custom paperback sizes from 4 to 8.5 in wide and 6 to 11.69 in tall, so an 8.25 × 11 in paperback is possible as a custom size, but KDP's Expanded Distribution table lists 8.25 × 11 in as not eligible with any ink and paper.
