KDP trim size recommender
Choose a KDP book size before margins and cover geometry.
Start from reading experience and content type, not the default in a design app. Then check whether the expected page count still feels practical.
Common trim sizes and what they change
A 5 × 8 inch book feels compact and usually creates more pages. A 6 × 9 inch trim is a flexible starting point for general nonfiction and many novels. A 7 × 10 or 8.5 × 11 inch page gives workbooks, manuals, tables, and large print more breathing room.
Trim affects line length, page count, print cost, spine width, image placement, and the physical feel of the book. Choose it before fine typography, but expect to revisit the choice if pagination becomes uncomfortable.
| Book type | Starting trim | Main tradeoff |
|---|---|---|
| Novel or memoir | 5.5 × 8.5 in | Compact feel with more pages |
| General nonfiction | 6 × 9 in | Flexible line length and cost |
| Workbook or manual | 8.5 × 11 in | More writing and visual space |
| Large print | 7 × 10 in | Larger text without extreme page growth |
