KDP low-content book cover setup checklist
Set up KDP paperback covers for journals, notebooks, planners, and workbooks with correct cover size, barcode planning, ISBN choice, and safe zones.
Low-content books still need exact cover dimensions
A notebook or planner can have simple interior pages, but the cover is still a paperback cover file. It needs the correct trim size, final page count, spine width, bleed, back cover, front cover, and barcode planning area.
Low-content cover decisions that affect design
Plan these before opening your design file. The ISBN and barcode decision can affect the back cover, while page count affects the spine.
| Decision | Design impact |
|---|---|
| Trim size | Common choices include 6 × 9, 7 × 10, 8 × 10, and 8.5 × 11; cover width and pixel canvas change with size |
| Page count | Changes spine width and full cover width |
| Publish without ISBN | KDP can place a barcode box on the back cover |
| Use your own ISBN | You may provide your own barcode if it meets formatting rules |
| Interior style | Journals and planners often need clean covers that leave barcode and trim safe zones clear |
Worked example: 8.5 × 11 workbook, 120 pages
For an 8.5 × 11 in low-content paperback with 120 black-and-white pages on white paper and 0.125 in bleed, the spine is 0.270 in. The full cover file is 17.520 × 11.25 in. At 300 PPI, the canvas is 5256 × 3375 px. A front-cover-only 2550 × 3300 px file is not enough for the full cover spread.
Back-cover barcode planning
If you publish without an ISBN or do not provide your own barcode, leave a clean area where KDP can place the barcode. Avoid putting journal prompts, pattern details, logos, author names, or decorative frames in that area.
