The recommended Kindle (KDP) ebook cover size is 2560×1600 pixels — a 1.6:1 height-to-width ratio — in JPG or TIFF under 50MB. Print cover dimensions depend on your trim size and page count, which set the spine width; KDP's cover calculator generates the exact template.
Like album art, book covers are bought at thumbnail size on Amazon: title readable at 100 pixels tall, strong genre signals, one focal image.
Generate a book cover with AI in your genre's visual language, then export at 2560×1600 for Kindle or upscale to 300 DPI for print.

Frequently asked questions
What size should a Kindle book cover be?+
2560×1600 pixels at 1.6:1 is Amazon's recommendation — sharp on every Kindle device and in store thumbnails.
Is ebook and print cover the same file?+
No. The ebook cover is just the front; print needs a full wraparound (back + spine + front) whose exact size depends on trim and page count.
Will my cover pass KDP review if it's AI-generated?+
Yes — KDP accepts AI-assisted covers; you're responsible for having rights to the image, and art you generate here is yours to use.
