Cover Setup Specifications
After calculating your dimensions, set up your design file with these settings:
| Setting | Value |
|---|---|
| File format | PDF (single page) |
| Colour space | RGB (KDP converts to CMYK) |
| Resolution | 300 DPI minimum |
| Bleed | 0.125" (3.175 mm) on all edges |
| Safe zone | 0.25" (6.4 mm) inside trim on all edges |
| Spine safe zone | 0.0625" (1.6 mm) on each side of spine |
| Barcode area | 2" x 1.2" white rectangle, bottom-right of back cover |
| Max file size | 650 MB |
Common Cover Mistakes to Avoid
- Text too close to spine — Keep text at least 0.0625" from spine edges
- Background not extending to bleed — Colours and images must fill the bleed area
- Wrong spine width — Recalculate if you change page count or paper type
- Low resolution images — Use 300 DPI minimum; 150 DPI will look blurry in print
- CMYK colour space — KDP accepts RGB and converts to CMYK itself, so an RGB file is fine
- Forgetting barcode space — Leave room for KDP’s auto-generated barcode
