How to Use Our KDP Book Cover Creator in 6 Steps
Forget complex math. Our online cover builder handles the technical specs. Follow this guide to make a compliant eBook or Paperback file using our KDP creator tool.
Step 1: Setup Your Specifications
Select format (eBook/Paperback). Example: 6x9 in, 200 pages, white paper. The cover creator outputs spine width = pages × paper factor (0.002252 in for white).
Step 2: Import or Generate Visuals
Upload your image or use our built-in AI book cover maker to generate unique, 300 DPI artwork from scratch. Large uploads auto-upscale to 300 DPI.
Step 3: Smart Background Matching
Upload a front cover and the Smart Color Picker recommends matching colors for the spine and back.
Step 4: Typography & Bestseller Styles
Add Title/Author. Use our bestseller style presets. Text typed here automatically syncs to the spine; hide front text via the Eye icon if you want spine-only text.
Step 5: Preflight Check
Run the preflight. Alerts include low DPI (under 300), missing 0.125 in bleed, or barcode quiet-zone conflicts before export.
Step 6: Preview & Export
Use Unlimited Preview. When ready, export a 300 DPI PDF/X-1a with bleed and barcode quiet zone.
