What does KDP state about large print?
Checked on 18 October 2026, the fonts page, the print options page, and the hardcover page do not mention a large-print checkbox, a large-print edition, or a font size used only for large print. The fonts page requires a minimum of 7 points so the text stays legible. The Word formatting help is a separate tip, not a large-print rule: body text between 9 and 12 point, with 9 point for a larger font such as Arial and 12 point for a smaller font such as Times New Roman. Large trim is different. Print options defines it as more than 6.12 inches wide or more than 9 inches tall, with a different printing cost from regular trim. That is the size of the book, not a large-print edition. A control inside an account, if one appears, is not stated on these public pages.[513][515][539]
- A 16-point large-print minimum is not stated on these KDP help pages.
- Large trim is a trim-size class. It is not a large-print designation.
- How Amazon labels the detail page when the type is larger is not stated.

What hardcover trim sizes, page counts, paper, and cover finishes does KDP publish?
The hardcover page says books are printed as case laminate: no dust jacket, with the art printed on the cover. Dust jackets, cloth bound, and other hardcover formats are not available. There are five trim sizes, and the page count is 75 to 550. Print options lists them in the table below. Large trim means more than 6.12 inches wide or more than 9 inches tall, so 6.14 by 9.21, 7 by 10, and 8.25 by 11 inches are large trim, and 5.5 by 8.5 and 6 by 9 inches are regular trim. Black ink on cream or white paper, at 50 to 61 pound, is available, as is premium color on 60 to 71 pound white paper. Groundwood is not available for hardcover, and standard color ink is not available for hardcover. Covers use 80 pound white paper, glossy or matte. Print elements says the cover wraps two mm case board, and a black-and-white headband is added if the manuscript is more than 120 pages. Endsheets are white or cream, to match the interior. Hardcover right-to-left publishing for Hebrew and Yiddish is not currently available. Hardcover is not supported on kdp.amazon.co.jp and is not available for Expanded Distribution.[514][515][517][518]
| Trim size | Black ink, white or cream | Premium color, white paper | Standard color and groundwood |
|---|---|---|---|
| 5.5 by 8.5 in | 75 to 550 | 75 to 550 | Not available |
| 6 by 9 in | 75 to 550 | 75 to 550 | Not available |
| 6.14 by 9.21 in, large trim | 75 to 550 | 75 to 550 | Not available |
| 7 by 10 in, large trim | 75 to 550 | 75 to 550 | Not available |
| 8.25 by 11 in, large trim | 75 to 550 | 75 to 550 | Not available |
- Glossy or matte does not change the printing cost.
- Proof copies and upload steps are on the paperback and hardcover answer.

What does KDP say about hardcover pricing and printing cost?
KDP prints on demand and subtracts printing cost from the royalty, with no upfront inventory. The formula is fixed cost plus page count times per-page cost. Its example for a 300-page regular-trim black-ink hardcover on the US marketplace is 5.65 USD plus 300 times 0.012 USD, which is 9.25 USD. Black-ink books of 75 to 108 pages incur only the fixed cost. The table also lists large trim, premium color, and other marketplaces. Those rows are not copied here. Royalty is 50 percent or 60 percent of list price, then minus printing cost. On Amazon.com, 9.98 USD and below is the 50 percent band, and 9.99 USD and above is the 60 percent band. The minimum list price is printing cost divided by that rate. The maximum on Amazon.com is 250 USD. The page also lists 250 GBP for Amazon.co.uk. A promotional sale price does not change the royalty.[516][517]
- The 9.25 USD figure is KDP's example for that one 300-page book.
- Editing and cover design sit outside this formula.

What hardcover options and trim or page limits does IngramSpark publish?
Checked on 18 October 2026, IngramSpark describes case laminate, jacketed case laminate, and digital cloth with or without a dust jacket. Textured cloth is only for books printed in the US and UK. White-paper hardcovers run from 5 by 8 inches to 8.5 by 11 inches. Creme or groundwood hardcovers run from 5 by 8 inches to 6.14 by 9.21 inches. Not every ink and paper combination is available at every trim. The trim page states no page-count maximum and no dollar print cost. It says a hardcover costs more than a paperback, depending on page count and specifications. The trim-size PDF prints 18 to 840 pages on rows marked HC, perfect-bound ranges of 18 to 900, 18 to 1,050, and 18 to 1,200 pages, and Max 400 pages beside 11 by 8.5 inches. A dust jacket must not exceed 6.14 by 9.252 inches. Jacketed covers can use case laminate or digital cloth where available. Custom sizes are 5 to 8.5 by 7 to 11 inches on white paper, and 5 to 6.14 by 7 to 9.252 inches on creme or groundwood. The PDF sends page-count limits to the Lightning Source file guide, which was not opened here. The title-setup article requires an even page count, a blank last even page, and a second PDF for a jacket. No large-print font size is stated.[519][520][522][540]
- A dollar print cost is not stated on the trim page. The FAQ points to the calculator.
- Using both printers for one print book is on the comparison answer.

Does a large print or hardcover edition need its own ISBN?
KDP says an existing paperback needs a unique ISBN for a hardcover edition, either a new KDP ISBN or one you own. A free KDP ISBN works only on KDP and shows the imprint Independently published. An ebook does not need an ISBN, and a low-content book cannot use the free one. A paperback or hardcover otherwise needs an ISBN. None of those pages says a large-print edition needs its own ISBN. Bowker requires one ISBN for each edition and format, and any variation needs a unique ISBN. It names hardback, paperback, ePub, PDF, Mobi, and audio. It does not name large print. On 18 October 2026 it lists 125 USD for one and 295 USD for ten. IngramSpark requires an ISBN for each format you distribute. Its three-ISBN example is an ebook, a paperback, and a hardcover, and it does not name large print. A free IngramSpark ISBN, for US self-publishers, is owned by IngramSpark, uses the imprint Indy Pub, cannot be transferred, and works only on IngramSpark. An owned ISBN bought in that account is listed at 85 USD for US publishers. A large-print ISBN rule is not stated here.[514][521][522][523][524][533]
- Hardcover and paperback are named as separate formats. Large print is not named.
- A free KDP ISBN stays on KDP. A free IngramSpark ISBN stays on IngramSpark.
- Agency prices change. Use the agency for the country where you operate.
