# Kindle Ebook Cover Size and Requirements

What KDP's help pages say about the size, format and content of a Kindle ebook cover, where its two pages disagree, and what a paperback cover needs instead.

By Shri and Sarath · Published October 20, 2026 · 5 min read

Everything below comes from KDP's own help pages, read on October 23, 2026. Two of them cover ebook covers, and they do not agree on every number, so the table shows each page's figure. Where a page says nothing, this guide says "KDP's page doesn't say" instead of guessing. KDP can change its pages at any time, so check the current ones before you upload.

## The size KDP asks for

KDP's help page on ebook cover criteria says that the format and quality of your cover must meet its specifications, and that an image which doesn't "may not be approved for use." It gives an ideal size, a minimum and a maximum.

| Item | What KDP says | Where |
| --- | --- | --- |
| File format | TIFF (.tif/.tiff) or JPEG (.jpeg/.jpg) on the cover criteria page. The guidelines page also accepts PNG and non-animated GIF, calls JPEG the preferred format, and doesn't support SVG | Both pages |
| Ideal dimensions | 2,560 pixels high by 1,600 pixels wide. For best quality on high definition devices, 2,500 pixels high | Both pages |
| Minimum dimensions | 1,000 pixels high by 625 pixels wide on the cover criteria page; at least 500 pixels on the longest side on the guidelines page | Both pages |
| Maximum dimensions | Not more than 10,000 pixels in height and in width | Both pages |
| Height to width ratio | An ideal ratio of at least 1.6:1: for every 1,000 pixels of width, 1,600 pixels of height | Cover criteria page |
| Resolution | 72 dpi on the cover criteria page, with a minimum of 300 PPI for best results in its note; 300 DPI/PPI minimum, as a recommendation, on the guidelines page | Both pages |
| File size | Less than 50MB on the cover criteria page; a maximum of 50 MB on the guidelines page | Both pages |
| Color profile | RGB. The guidelines page recommends RGB and says CMYK files are accepted and converted to RGB automatically | Both pages |
| Smallest displayed | Covers under 500 pixels on the longest side are not displayed on the website | Guidelines page |

Kindle ebook cover specifications, as KDP states them

The ratio is the same shape as the ideal size: 2,560 divided by 1,600 is 1.6. KDP's pages don't say what happens to a cover with a different ratio (the guidelines page only refuses one past 500:1), so a cover close to 1.6:1 is the safe choice.

If your cover is smaller than the recommended 2,560 by 1,600, KDP says a warning is shown at upload. It strongly recommends making a new image that meets the size, and says not to stretch the old one, "because this may lower the image quality." It also notes that it applies additional compression when it displays covers, so you should upload with minimal compression.

## Where KDP's two pages disagree

The cover criteria page lists 72 dpi, TIFF or JPEG, and a minimum of 1,000 by 625 pixels. The cover image guidelines page recommends at least 300 DPI/PPI, also takes PNG and GIF, and sets its minimum at 500 pixels on the longest side. Both are KDP's words, and KDP's pages don't say which one wins. This is our advice, not KDP's: a JPEG at about 2,560 by 1,600 pixels, saved in RGB at 300 PPI and well under 50MB, sits inside both sets of numbers.

> **Our advice, labelled as such** When two official numbers differ, pick the file that satisfies the stricter one. A JPEG is on both pages' lists, 2,560 by 1,600 pixels clears both minimums, and an RGB file needs no conversion.

## What goes on the cover

KDP's cover image guidelines page says the cover image must not infringe another publisher's or artist's copyright, and must not mention pricing or other temporary promotional offers. The cover criteria page asks you to make sure the cover follows KDP's content guidelines and that you have all rights necessary for its content.

Its pre-publish checks, in KDP's words, cover the following:

- The cover includes the title and the author or contributor information.
- The cover doesn't include the spine, bar code, back cover or (optional) inside flap.
- No typos, watermarks, or placeholder or template text.
- Any text doesn't contradict your Amazon detail page, for example an author name or title spelled differently.
- The cover language matches the language in the book.
- Text is clear, and not blurred, cut off or fading into the background.

KDP's metadata guidelines add that the title, subtitle, author name and series information on your cover should match the corresponding metadata fields, and that covers which closely resemble another book's layout, color scheme, fonts or images aren't allowed. KDP's page doesn't give a minimum or maximum text size, a font list or a limit on how much text the cover may carry.

## Borders and pale covers

KDP notes that cover art with white or very light backgrounds can seem to disappear against the white background of the page, and suggests a narrow (3-4 pixel) border in medium gray to define the edges.

## A paperback cover is a different file

Do not reuse the ebook image for a paperback. KDP's paperback cover page says the cover must be a single PDF file that includes the back cover, spine and front cover as one image, sized with a 0.125 inch (3.2 mm) bleed on the top, bottom and outside edges. The spine width depends on page count, and KDP says spine text needs at least 79 pages. It points to its own cover calculator and template generator for the exact size, and its page sets a 650MB conversion limit with 40MB or less recommended. Ebooks have none of this: no spine, no bleed, no barcode.

|  | Kindle ebook cover | Paperback cover |
| --- | --- | --- |
| File | An image, JPEG preferred, front cover only | One PDF with back, spine and front |
| Size | Ideal 2,560 by 1,600 pixels | Set by trim size, page count and paper, with bleed; KDP gives a calculator |
| Spine and barcode | Must not be on the cover | Part of the file; spine text needs at least 79 pages |

## Questions

**What size should a Kindle ebook cover be?** KDP says the ideal is 2,560 pixels high by 1,600 pixels wide, and 2,500 pixels high for best quality on high definition devices. Its cover criteria page sets a minimum of 1,000 by 625, and both of its cover pages a maximum of 10,000 pixels in height and in width.

**What file format does KDP accept for an ebook cover?** KDP's cover criteria page lists TIFF (.tif/.tiff) or JPEG (.jpeg/.jpg). Its cover image guidelines page also accepts PNG and non-animated GIF, calls JPEG the preferred format, and says SVG files are not supported.

**Does the cover need a spine or barcode?** No. KDP's checks say an ebook cover shouldn't include the spine, bar code, back cover or inside flap. Those belong to a paperback cover, which is a separate PDF file.

**Can I put a price or a sale on the cover?** No. KDP says the cover image must not mention pricing or other temporary promotional offers.

**Is my cover required to match the book?** KDP asks that text on the cover doesn't contradict your detail page, that the cover language matches the book's language, and that title, subtitle, author name and series information match your metadata fields.

**Do I have to say my cover was made with AI?** KDP's content guidelines say you must tell it about AI-generated content, including cover and interior images, when you publish or republish a book. It says AI-assisted content need not be disclosed. Read the definitions on its page; they are specific.
