What are the correct KDP and print book cover dimensions?
TL;DR: Ebook covers should generally be 2,560 × 1,600 pixels at a 1.6:1 ratio. Print book covers require a full-wrap file containing the front cover, spine, and back cover in a single image. Final dimensions depend on trim size, page count, and paper type. All print covers should be exported at 300 DPI for professional print quality.
KDP and IngramSpark both provide official cover calculators and templates to generate exact specifications for your book.
Full Answer:
Book cover dimensions are one of the most technical parts of self-publishing, and getting them wrong can lead to blurry prints, rejected uploads, incorrect spine widths, or covers that do not align properly during production.
The correct dimensions depend entirely on whether you are creating:
- An ebook cover
- A paperback cover
- A hardcover dust jacket
- A hardcover case laminate
For Kindle ebook covers, Amazon recommends:
- 2,560 pixels tall
- 1,600 pixels wide
- 1.6:1 aspect ratio
- JPEG or TIFF format
- RGB color profile
This size ensures the cover displays sharply across Kindle devices, Amazon product pages, mobile thumbnails, and advertising placements.
Technically, Amazon allows smaller sizes, but uploading at the recommended dimensions creates noticeably better visual quality and future-proofs your files for higher-resolution displays.
Print book cover dimensions are more complex.
Unlike ebook covers, print covers are not just a front image.
A print cover file includes:
- Front cover
- Spine
- Back cover
- Bleed areas
- Safe zones
All of these components exist inside one continuous wraparound file.
The exact dimensions depend on:
- Trim size
- Page count
- Paper color
- Binding type
- Platform requirements
Trim size refers to the final dimensions of the printed book after trimming. Common trim sizes include:
- 5″ × 8″
- 5.5″ × 8.5″
- 6″ × 9″ (most common for nonfiction and novels)
- 8.5″ × 11″ (common for workbooks and manuals)
The spine width changes based on page count and paper stock.
A 120-page paperback has a thin spine. A 600-page fantasy novel has a thick spine. That spine width directly changes the total cover width.
For example:
A standard 6″ × 9″ paperback with 300 pages on cream paper might require:
- 6″ back cover
- ~0.68″ spine
- 6″ front cover
- 0.125″ bleed on outer edges
Total width becomes approximately 12.93 inches.
At 300 DPI, that translates to roughly:
- 3,879 pixels wide
- 2,775 pixels tall
300 DPI is the professional print standard.
Anything below 300 DPI risks blurry text, soft images, or pixelation in the final printed book.
This matters especially for:
- Typography
- Illustrations
- Back cover text
- Barcode areas
- Detailed artwork
Bleed and safe zones are also critical.
Bleed is extra image area extending beyond the trim edge to prevent white slivers during cutting.
Safe zones keep text and important design elements away from edges and spine folds where trimming variation can cut them off.
Both Amazon KDP and IngramSpark provide official cover calculators and downloadable templates.
These templates automatically calculate:
- Spine width
- Total cover dimensions
- Bleed requirements
- Barcode placement zones
- Safe margins
Always design directly against the platform-generated template rather than guessing measurements manually.
Common book cover specification mistakes include:
- Incorrect spine width
- Low-resolution artwork
- Text too close to trim edges
- Using RGB instead of CMYK for print workflows
- Ignoring bleed settings
- Unreadable back-cover text
If you are producing both ebook and print editions, remember that these are separate files with separate technical requirements.
The ebook cover is only the front image.
The print cover is an entire printable wraparound production file.
Authors comparing publishing workflows often evaluate the best writing platform for authors when managing cover generation, print formatting, trim calculations, and direct KDP/IngramSpark export workflows inside a single system.
