Page limits by ink and paper
KDP sets a minimum and a maximum page count for every combination of trim, binding, ink and paper. At 8.25 × 11 in:
| Ink and paper | Hardcover pages | Spine per page |
|---|---|---|
| Black & white · white paper | 75–550 | 0.002252 in |
| Black & white · cream paper | 75–550 | 0.0025 in |
| Black & white · groundwood paper | Not offered | – |
| Standard color · white paper | Not offered | – |
| Premium color · white paper | 75–550 | 0.002347 in |
KDP counts every page, blank ones included, and rounds an odd count up to the next even number, so the 75-page hardcover minimum is 76 pages in practice. The spine factor is the thickness of one page; the spine width calculator multiplies it by your page count.
Expanded Distribution (40% royalty) is for paperbacks only, so it doesn't apply to a hardcover-only size.
Margins and text area at 8.25 × 11 in
KDP’s minimum inside margin (the gutter) grows with the page count. The top, bottom and outside margins must be at least 0.25 in, or 0.375 in when the interior has bleed. With those minimums, the text block can be this wide at 8.25 × 11 in:
| Pages | Minimum gutter | Max text width | With bleed |
|---|---|---|---|
| 75–150 | 0.375 in (9.6 mm) | 7.625 in | 7.5 in |
| 151–300 | 0.5 in (12.7 mm) | 7.5 in | 7.375 in |
| 301–500 | 0.625 in (15.9 mm) | 7.375 in | 7.25 in |
| 501–550 | 0.75 in (19.1 mm) | 7.25 in | 7.125 in |
The text block can be up to 10.5 in tall (10.25 in with bleed). These are KDP’s minimums; most book designers leave more room, especially at the gutter of thick books. See every margin to scale in margins and bleed.
Full-wrap cover size at 8.25 × 11 in
The cover is one PDF: back cover, spine and front cover side by side. Its width depends on the spine, so it changes with the page count and the paper.
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.

Printing cost at 8.25 × 11 in on Amazon.com
KDP deducts the printing cost from each sale. Examples on Amazon.com in US dollars, with the lowest list price KDP accepts for each:
| Pages | B&W white | Premium color |
|---|---|---|
| 100 | $7.49flat fee · min. list price $12.48 | $13.65min. list price $22.75 |
| 200 | $9.05min. list price $15.08 | $21.65min. list price $36.08 |
On Amazon.com, black-and-white hardcovers up to 108 pages pay a flat printing fee; above that, and for premium color, the cost is a fixed fee plus a price per page.
8.25 × 11 in is a large trim (wider than 6.12 in and taller than 9 in), so it prints at KDP's large-trim rate: a 300-page black-and-white hardcover costs $10.75 to print on Amazon.com, against $9.25 at 6 × 9 in, a regular trim. That is $1.50 more per copy.
Other marketplaces use their own price tables: compare all of them in the printing cost calculator, and see what you earn per copy with the royalty calculator.
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.
