  2. Save a master PSD/PNG.
  3. Resize copies for each store with the Image Resizer.
  4. Set the right DPI for each store via DPI Converter.
  5. Save as JPEG quality 95 or PNG (KDP accepts both).
  6. Confirm file size under store limit (usually 50 MB).

If you also publish a paperback through KDP Print, you need a separate full-cover wrap (front + spine + back) at 300 DPI with bleed. Generate spine width from KDP’s template tool based on page count.

Frequently Asked Questions

What size should a Kindle eBook cover be?
Amazon KDP recommends 2560 × 1600 px (8:5 aspect ratio) at 300 DPI for the eBook cover. The matching paperback cover requires a separate full wrap with bleed.
What is the best DPI for eBook covers?
300 DPI for stores that validate against it (Kindle, Kobo, Google Play, Smashwords). Apple Books accepts 72 DPI. Pixel size matters more than DPI for actual display sharpness.
What aspect ratio for eBook covers?
2:3 is the most common (1600×2400, 2400×3600). Kindle is the exception at 8:5 (2560×1600).
Should eBook covers be RGB or CMYK?
sRGB — eBooks display only on screens. CMYK is only needed for the matching printed paperback cover.
