When to choose 6x9 hardcover for KDP
6x9 hardcovers are well‑suited for premium nonfiction, gift editions, textbooks and any project where durability and perceived value matter. They use the same interior trim as 6x9 paperbacks, but the cover math is different because of boards, hinge and wrap.
6x9 hardcover example (120 pages)
- Trim size: 6.0 x 9.0"
- Spine width: 0.459"
- Full cover size: 14.034" × 10.417"
- Paper type: White Paper
This 120‑page 6x9 hardcover gives you enough spine width for clear title text while keeping the book comfortable to read in bed or at a desk. The full cover size includes hinge and wrap so the boards and case laminate line up correctly after binding.

How 6x9 KDP hardcover cover size differs from paperback
6x9 hardcovers use the same interior trim size as 6x9 paperbacks, but add hinge and wrap. That means the full cover width and height are larger than an equivalent paperback.
| Format | Pages | Trim size | Spine width | Full cover size |
|---|---|---|---|---|
| 6x9 paperback (120 pages) | 120 | 6.0 × 9.0" | 0.27" | 12.52" × 9.25" |
| 6x9 hardcover (120 pages) | 120 | 6.0 x 9.0" | 0.459" | 14.034" × 10.417" |
For example, a 120-page 6x9 KDP hardcover on White Paper uses a6.0 x 9.0" trim, a 0.459" spine and a full cover size of 14.034" × 10.417" including hinge and wrap.
In practice, you cannot reuse a 6x9 paperback template for a 6x9 hardcover. The hardcover math adds extra width and height to account for boards and the turn‑in of the case laminate.
How to use this 6x9 hardcover size guide
Understand "Case Laminate"Hardcover cover files are physically larger than paperbacks. Your design is printed on paper and glued onto a hard board casing, so the template includes extra space for that structure.
Account for WrapDo not drop a 6x9 paperback file into hardcover. The 6x9 hardcover template adds wrap (about 0.59" / 15 mm) so the printed case can fold neatly around the boards.
Mind the "Hinge"Keep titles and key text out of the hinge zone — the 10 mm gutter between spine and cover where the book bends when opened.
Extend BackgroundMake sure background artwork covers the entire wrap zone so folded edges look clean on the outside and where they turn in on the inside of the case laminate.
