Hardcover
| Pages | Paper | Spine | Full cover (in) | Full cover (mm) | Spine text |
|---|---|---|---|---|---|
| 80 | B&W white | 0.369 in | 18.444 × 12.417 | 468.5 × 315.4 | Yes |
| 120 | B&W white | 0.459 in | 18.534 × 12.417 | 470.8 × 315.4 | Yes |
| 200 | B&W white | 0.639 in | 18.714 × 12.417 | 475.3 × 315.4 | Yes |
A hardcover cover is larger than the page: each board is 5 mm wider and 6 mm taller than the trim, the spine adds 4.8 mm to the paper, and the art wraps 15 mm around every edge. Keep text out of the 10 mm hinge next to the spine.
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.

When to choose 8.25 × 11 in
- It is hardcover only: for a paperback of about the same size, choose 8.5 × 11 in.
- A KDP hardcover needs at least 75 pages (76 once rounded to an even count), so a 32-page picture book can't be a hardcover at this size or any other; at that length it has to be a paperback.
- KDP hardcovers are case laminate: the art is printed on the case itself, and KDP offers no dust jacket or cloth binding.

What cover size does an 8.25 × 11 in book need on KDP?
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.
Can an 8.25 × 11 in book be a paperback on KDP?
