What Amazon KDP eBook cover means in practice
Minimum 1000 pixels tall by 625 wide, ideally 2560 by 1600, and no more than 10000 pixels on either side or 50 MB. Amazon asks for a height-to-width ratio of at least 1.6:1 and an RGB colour profile. KDP also accepts TIFF, which FileBelow does not produce — use JPEG.
A cover that does not meet the specification blocks publication, and the cover thumbnail is the single thing a browsing reader sees first.
Where this image actually appears
The cover of a self-published title. It appears as a small thumbnail in Kindle store search results, in also-bought rows, and in a reader's own library — and only rarely at anything approaching full size. It is the single strongest signal of whether a self-published book looks professional.
Preparing one properly
Design at the thumbnail size and check it there. The title has to be legible at roughly the size of a postage stamp, which usually means far fewer words and a far larger typeface than a print cover would use. Strong contrast between the title and the background matters more than any other decision.
The mistake people make
Adapting a print cover directly. A print cover is designed to be held; its typography, its subtitle, its author credit and its cover quotes all assume a reader can see them at full size. Shrunk to a search result none of that is readable, and the result looks like a busy grey rectangle beside covers designed for the medium.
Meeting the requirements
Choosing Amazon KDP above sets every rule in the table at once, and the result panel reports each one with a pass or a fail rather than leaving you to check. Resolution is kept as high as the other rules allow, and never reduced below any published minimum.
To see what is wrong before changing anything, the Amazon KDP requirement check reports every rule against your file without processing it.
Common questions
- What size should a Amazon KDP ebook cover be?
- at least 625px wide · under 50 MB · JPEG. Those are the values published by Amazon KDP itself, read from its documentation on 2026-08-22 — the source link is on this page so you can check it. Platforms change requirements without announcing it, so verify before anything important.
- Does a Kindle book need a separate cover from the print edition?
- Technically no, practically almost always yes. A print cover carries elements sized for something held in the hand, and none of them survive being shown as a small thumbnail. Most successful self-published titles use a simplified version of the same design with a much larger title.
- Should the cover include the author name?
- Yes, and it is displayed separately in the listing as well. The name is normally the smallest element on the cover unless the author is the reason somebody is buying, in which case the hierarchy reverses. Either way, the title has to be the thing that reads first at thumbnail size.
- Is my image uploaded when I use this page?
- No. The image is opened, measured and processed by your own browser. This site is entirely static and has no server that could receive a file, which you can confirm in your browser’s network tab or by going offline after the page has loaded.
