Step 1: Lock the print spec early
Decide Paperback vs Hardcover and confirm your trim size. If you haven’t chosen yet, use Amazon Book Dimensions: KDP Sizes, Trim Sizes, and Cover Math to make a confident choice.
Step 2: Generate exact cover dimensions
Use KDP Book Size Calculator to get the full cover size (front + spine + back + bleed). If you prefer a shortcut, start with KDP Cover Templates.
Step 3: Confirm spine width before you place spine text
Re-check spine width once the interior page count is final. Use Spine Width for KDP: The Practical Guide (+ Calculator Tips) so your spine text doesn’t drift or get clipped.
Step 4: Design for readability (thumbnail + print)
Apply hierarchy and contrast, and avoid fragile typography. If you want a structured approach, read KDP Cover Design Principles: Hierarchy, Contrast, and Readability and implement those rules in your editor.
Step 5: Preflight against KDP requirements
Before export, validate bleed, safe zones, barcode clearance, and overall dimensions. Use KDP Cover Requirements (Bleed, DPI, Safe Zones, Barcode) as your spec checklist.
Step 6: Export and sanity-check output quality
Export with settings that keep text crisp. If anything looks wrong (size mismatch, pixelated fonts, barcode collision), troubleshoot using Common KDP Cover Mistakes (and How to Fix Them).
Step 7: Upload with confidence
- Reconfirm dimensions match your calculator output.
- Check that important text stays inside safe zones.
- Verify barcode area is clear on the back cover.
- Confirm spine text looks centered in preview.
- Save a reusable checklist for your next book.
