How do I set up Photoshop / Canva for KDP covers?
Photoshop
- • Units: Inches; Resolution: 300 DPI
- • Color Mode: CMYK for print preview
- • Canvas Size: Use Full Width × Full Height from the calculator
- • Export: PDF/X-1a:2001 or High Quality Print
Canva
- • Create Design > Custom Size: Enter Inches
- • Width/Height: Use Full Width / Full Height values
- • Keep critical text/logos inside the Safe Zone
- • Download: PDF Print (select "Crop marks and bleed")
How to use the KDP Cover Calculator & Template Generator
Confirm the final page count (any even number between 24–1000); this determines the spine width.
Choose cover type (paperback/hardcover), paper type and trim size.
Review the inch/mm output and double-check bleed and safe zone.
Click "Open this size in KDP Cover Creator (Free)" to design your cover online.
Why size errors are the #1 KDP rejection
KDP checks dimensions first. Using a precise KDP Cover Calculator is critical. If spine, bleed or safe zone are off by as little as 0.1 in, files may be rejected or the print can be misaligned.
KDP Cover Calculator Terminology: Dimensions, Bleed & Spine
| Term | Definition | Value |
|---|---|---|
| Bleed (paperback) | Extra area beyond trim to avoid white edges | 0.125 in |
| Safe zone | Keep text/logos inside this distance from trim | ≥ 0.125 in |
| Spine width | Pages × paper thickness (varies by stock) | dynamic |
| Hinge (hardcover) | Flexible zone next to spine | 0.394 in each side |
| Wrap / Turn‑in (hardcover) | Extra area that wraps around boards | 0.591 in each side/top/bottom |
Paperback vs Hardcover KDP Cover Size Differences
- • Paperback: width = 2 × trim width + spine + 2 × 0.125 in; height = trim height + 2 × 0.125 in.
- • Hardcover (case laminate): width = 2 × trim width + spine + 0.394 + 2 × 0.591; height = trim height + 0.236 + 2 × 0.591.
- • Spine width depends only on pages × paper thickness (white/cream/color).
Common KDP Cover Size Errors & Calculator Fixes
| Error | Cause | Fix |
|---|---|---|
| Incorrect trim size | Canvas not set to full width/height including bleed | Recreate the canvas with the calculator output (in/mm). |
| Spine text cutoff | Text outside spine safe zone or font too large | Reduce the font size or increase pages; keep text inside the safe zone. |
| White edge after trimming | Background doesn’t fill the bleed area | Extend artwork into the 0.125 in bleed on outer edges. |
| Blurry print | Effective resolution < 300 DPI at final size | Export a 300 DPI print‑ready PDF. |
