Key Takeaways
- An eBook cover is a single front-only image; a print cover is a wraparound: back, spine, and front in one file.
- Recommended eBook cover: about 2,560 × 1,600 px (a 1.6:1 height-to-width ratio) at 300 DPI.
- Print spine width depends on page count and paper, so you can’t build a print cover until your interior is final.
- Print covers need bleed (usually 0.125"), safe margins, and 300 DPI, eBooks don’t need bleed.
- KDP and IngramSpark have slightly different templates and spine math, always generate a template for your exact specs.
Your eBook cover and your print cover are not the same file resized. They’re built differently, sized differently, and have different technical requirements. Getting the specs wrong is one of the most common reasons covers get rejected or print badly. Here’s a clear, practical guide to the dimensions and specs for each, so your cover looks sharp on every screen and shelf.
Standard eBook Cover Dimensions
eBook covers are the simplest: one front-facing image, no spine, no back. The widely recommended size is 2,560 px tall × 1,600 px wide, a 1.6:1 ratio that looks crisp on Kindle, Apple Books, Kobo, and every retailer thumbnail. Key points:
- Ratio: aim for 1.6:1 (height:width). Most retailers prefer it.
- Minimum: at least 1,000 px on the shortest side; bigger is better for sharpness.
- Format: JPEG or TIFF, RGB color, 72–300 DPI (resolution matters less on screen than pixel count).
- No bleed needed: the image is displayed as-is on screen.
Print Wraparound Cover Anatomy (Front, Spine, Back)
A print cover is a single flat file that wraps around the whole book. Laid out left to right it contains:
- Back cover (left): blurb, author bio, ISBN/barcode area, reviews.
- Spine (center): title, author name, and publisher logo, sized to your page count.
- Front cover (right): the design readers see, mirroring your eBook cover.
Because it’s one continuous image, the artwork, colors, and background must flow seamlessly across all three panels.
Spine Width Calculation by Page Count
The spine is where most authors get tripped up, its width is determined by your page count and paper type, so it changes as your interior changes. The rough formula:
Spine width = number of pages × paper thickness per page. For typical print-on-demand white paper that’s about 0.0025″ per page; cream paper is slightly thicker (~0.0026″). Example: a 300-page book on white paper ≈ 300 × 0.0025 ≈ 0.75″ spine.
This is exactly why you can’t finalize a print cover until your interior formatting is locked, the final page count sets the spine. Books under ~80–100 pages often can’t carry spine text at all.
Bleed, Margins, and Resolution Requirements
- Bleed: print covers need bleed, usually 0.125″ beyond the trim on all outer edges, so there are no white slivers when the cover is cut.
- Safe margin: keep important text and logos at least ~0.25″ away from trim and spine edges.
- Resolution: print needs 300 DPI at full size, low-res images that look fine on screen will look blurry or pixelated in print.
- Color: print uses CMYK; screen uses RGB. Colors can shift between them, which is why a printed proof matters.

The two biggest print platforms have slightly different requirements, and a cover built for one isn’t automatically valid for the other:
| Spec | Amazon KDP | IngramSpark |
|---|---|---|
| Cover file | Single wraparound PDF | Single wraparound PDF |
| Bleed | 0.125″ | 0.125″ |
| Spine text min pages | ~100 pages | ~80 pages |
| Template source | KDP cover calculator | IngramSpark cover generator |
| Best practice | Always generate a fresh template for your exact trim size, page count, and paper | |
