eBook Cover Size Guide — Exact Dimensions for Every Major Platform
Every major eBook platform has different cover image requirements. Use the wrong dimensions and your cover displays with black bars, distorted proportions, or a blurry resolution on certain devices. This guide gives you the exact specs for every platform in one place.
Cover Dimension Requirements by Platform
| Platform | Minimum (w × h) | Ideal (w × h) | Ratio | Format | Max Size |
|---|---|---|---|---|---|
| Amazon KDP | 625 × 1,000px | 1,600 × 2,560px | 1:1.6 (w:h) | JPEG (preferred) or TIFF | 5MB |
| Apple Books | 1,400 × 1,873px | 2,800 × 3,746px | ≈0.75:1 (w:h) | JPEG | No limit |
| Kobo | 800 × 1,200px | 1,600 × 2,400px | 2:3 (w:h) | JPEG | 5MB |
| Google Play Books | 1,000 × 1,500px | 2,000 × 3,000px | 2:3 (w:h) | JPEG or PNG | 4MB |
| Barnes & Noble | 750 × 1,000px | 2,000 × 2,666px | 3:4 (w:h) | JPEG | 8MB |
| IngramSpark | 1,600 × 2,400px | 2,400 × 3,600px | 2:3 (w:h) | JPEG | 40MB |
| Draft2Digital | 1,400 × 2,100px | 2,500 × 3,750px | 2:3 (w:h) | JPEG or PNG | 10MB |
All sizes are width × height in pixels. All platforms require RGB colour space. Amazon KDP recommends 1,600 × 2,560px (2,560px tall) for best display on high-resolution screens, and covers under 500px on the shortest side are not shown on Amazon at all — see KDP’s Cover Image Guidelines. Platform requirements change, so confirm on each retailer’s help page before you upload.
The Universal Cover Size That Works for Every Platform
You do not need a different cover file for every platform.
A single portrait cover at 1,600 × 2,560px (width × height), saved as an RGB JPEG under 5MB, meets the upload requirements of Amazon KDP, Apple Books, Kobo, Google Play, Barnes & Noble, and Draft2Digital. Platforms that prefer a 2:3 shape display it with only a slight difference in proportion.
When a second version is worth making
Every eBook cover is portrait — taller than it is wide. Amazon’s recommended shape is 1:1.6, while Kobo, Google Play, IngramSpark, and Draft2Digital are built around 2:3, which is slightly wider. One 1,600 × 2,560px file is accepted everywhere. If your design has text or artwork close to the edges, export a second 2:3 version (for example 1,600 × 2,400px) for the 2:3 platforms so nothing sits too close to the edge.

Frequently Asked Questions
Not directly. Print covers require CMYK colour space, specific bleed dimensions, and a spine and back cover. eBook covers are the front cover only in RGB. Your designer can export two versions from the same source file — one for print, one for eBook.
Amazon compresses cover images for display in search results. A cover that looks sharp at full size may appear slightly soft in thumbnails — this is normal. If it looks noticeably blurry, your source file may be below the recommended 1,600 × 2,560px, or it may have been enlarged from a smaller image — KDP advises never stretching a small image to meet the size.
Cover size does not directly affect search ranking. However, a professional-looking cover at the correct dimensions affects click-through rate from search results — which indirectly affects sales velocity, which does affect Amazon’s internal ranking algorithm.
Adobe Photoshop and Canva are the most common tools. Canva has free Kindle cover templates at the correct dimensions — search “Kindle book cover” in Canva’s template library. Export at the full pixel size (at least 1,600 × 2,560px), RGB, as a JPEG.
