KDP Hardcover vs Paperback: Is the Hardcover Worth Adding?
A KDP hardcover costs more to print than the paperback, comes in five sizes and has no Expanded Distribution. The two editions compared line by line and in dollars, and the kinds of book where the extra edition earns its place.
Published October 17, 2026. Figures are calculated from KDP's published rates when the page is built.
A hardcover is a second print edition of the same text, so the comparison comes down to two things: what the hardcover can't do, and what each copy costs. Royalty rules are not among the differences. KDP's Hardcover Royalty page uses the same 50% and 60% rates and the same $9.99, €9.99 and £7.99 lines as paperbacks, so the $9.99 threshold matters just as much for a hardcover priced near it.
The two editions side by side
| Paperback | Hardcover | |
|---|---|---|
| Binding | Paperback cover, glossy or matte | Case laminate |
| Trim sizes | Standard sizes, or custom from 4" to 8.5" wide and 6" to 11.69" tall | Five only: 5.5" x 8.5", 6" x 9", 6.14" x 9.21", 7" x 10", 8.25" x 11" |
| Pages (black ink, white paper) | 24-828 | 75-550 |
| Ink and paper | Black on cream, white or groundwood; standard color; premium color | Black on cream or white; premium color |
| Expanded Distribution | Available (40% royalty) | Not available |
| Fixed cost per book above the flat band (Amazon.com) | $1.00 | $5.65 |
| Per-page cost, black ink, regular trim (Amazon.com) | $0.012 | $0.012 |
| Royalty | 60% at or above $9.99 (£7.99, €9.99), 50% below, minus printing | |
Sources: KDP's Print Options page for trims, page counts, inks and the case laminate binding; the Hardcover Printing Cost page for costs; the Hardcover Royalty page, which covers sales through Amazon only, for royalties. The paperback side of the comparison is laid out in full in the printing cost guide. Hardcover publishing isn't supported on kdp.amazon.co.jp, according to both hardcover pages.
The per-page rate for black ink is the same in both editions on Amazon.com. The whole difference in cost sits in the fixed part: the case adds the same amount to every hardcover, whether it has 120 pages or 500. Black-ink hardcovers also have a flat band, from 75 to 108 pages, at $6.80 for a regular trim; at 110 pages the per-page formula takes over and the cost is $6.97, up from $6.80 at 108.
Three books, both editions
Each book below is priced as a hypothetical example on Amazon.com. The last row of each block is the hardcover list price at which it would earn the same per copy as the paperback.
| Book | Paperback | Hardcover | |
|---|---|---|---|
| Poetry collection 90 pages, 5.5" x 8.5", black, cream | Printing cost | $2.30 | $6.80 |
| List price | $9.99 | $19.99 | |
| Royalty per copy | $3.69 | $5.19 | |
| Hardcover price to match | – | $17.49 | |
| Historical novel 380 pages, 6" x 9", black, cream | Printing cost | $5.56 | $10.21 |
| List price | $17.99 | $27.99 | |
| Royalty per copy | $5.23 | $6.58 | |
| Hardcover price to match | – | $25.74 | |
| Picture book 80 pages, 8.25" x 11", premium color | Printing cost | $7.40 | $12.05 |
| List price | $14.99 | $24.99 | |
| Royalty per copy | $1.59 | $2.94 | |
| Hardcover price to match | – | $22.74 |
The poetry collection is on the flat band in both editions, so the gap is the difference between two flat fees: $4.50. At $19.99 the hardcover earns $5.19 against $3.69 for the paperback. Short books are where hardcovers look worst on cost, because the case's fixed price is large relative to a small paperback bill.
The historical novel pays $4.65 more to print in hardcover, which is exactly the difference in fixed cost. At 60%, the hardcover price has to be about $7.75 higher than the paperback just to stand still, so $25.74 matches the paperback's $5.23. At $27.99 it earns $6.58.
The picture book is a large trim in premium color. Premium color hardcovers have no flat band, so all 80 pages are charged from the first. The hardcover costs $12.05 against $7.40 for the paperback, and needs to sell at $22.74 to earn the paperback's $1.59.
The same novel outside the US
The gap between the editions is a different size in each marketplace, because each has its own fixed costs. Here is the 380-page novel on cream paper again, with the extra printing cost of the hardcover and how much higher its price must be, at 60%, to earn the same as the paperback.
| Marketplace | Paperback | Hardcover | Extra per copy | Price rise to match |
|---|---|---|---|---|
| Amazon.com | $5.56 | $10.21 | $4.65 | $7.75 |
| Amazon.co.uk | £4.65 | £7.95 | £3.30 | £5.50 |
| Euro stores | €5.31 | €9.21 | €3.90 | €6.50 |
The lowest hardcover price KDP would accept for this book is $17.02 on Amazon.com, £13.25 on Amazon.co.uk and €15.36 on the euro stores. Prices converted from a single US price won't necessarily keep the margin over the paperback that you planned in dollars, so check the hardcover in each marketplace.

Which books suit which edition
The matrix below works from the rules and costs above, not from sales data. Whether readers in your category buy hardcovers is something only your own market research and sales can tell you.
| Your book | Recommendation | Why |
|---|---|---|
| Under 75 pages | Paperback only | KDP hardcovers start at 75 pages. Adding pages just to qualify changes the book for the reader. |
| Over 550 pages | Paperback only, or split the book | Hardcovers stop at 550. A 550-page cream hardcover already costs $12.25 against $7.60 in paperback. |
| Needs standard color or groundwood paper | Paperback only | Neither is offered for hardcovers. The hardcover would have to move to premium color or cream/white paper, at a higher cost. |
| Custom or unusual trim size | Paperback, or redesign for a hardcover trim | Hardcovers come in five fixed trims. A different trim means a reformatted interior. |
| Relies on bookstores and libraries via Expanded Distribution | Paperback for that channel | Expanded Distribution isn't available for KDP hardcovers. |
| Black ink, 110-550 pages, standard trim | Hardcover is a low-risk add-on | The extra cost is a fixed $4.65 a copy on Amazon.com; a price $7.75 above the paperback covers it. |
| Black ink, 75-108 pages | Hardcover only at a clearly higher price | The flat fee ($6.80) is 3.0 times the paperback's ($2.30); the hardcover needs a much higher price to earn the same. |
| Premium color | Price the hardcover from its cost | No flat band and a higher fixed cost; work out the matching price before choosing one. |
The paperback stays the base edition
On the numbers, a hardcover is never a substitute for the paperback: it can do less (fewer trims, a narrower page range, no standard color or groundwood, no Expanded Distribution) and costs more for every book. It makes sense as an addition when the extra fixed cost is a small part of a price readers will pay, which is the long black-ink book on a standard trim.
Budget for a second cover file, too. KDP's Hardcover Print Elements page explains that the printed cover is wrapped around two-millimetre case board, with a wrap section that folds over and is glued to the inside of the case, and the spine is flat. None of that exists on a paperback, which is why KDP's cover calculator treats hardcover as a separate binding type with its own dimensions and template. A paperback wrap resized by eye will not fit it.
