AI Book Cover Maker
Covers that signal the genre before anyone reads the blurb.
A cover’s first job is to say which shelf the book belongs on. This AI book cover generator works genre-first — the palette, illustration style and type treatment that tell a browsing reader "this is a cosy romance" or "this is hard sci-fi" before they read a word. Covers come back at Kindle proportions with the title set, and export without a watermark.

Why use this instead of a template
Genre-literate
Romance, thriller, literary, sci-fi and business non-fiction each have visual conventions. Naming the genre applies them.
Works as a thumbnail
Most covers are first seen 200 pixels tall in a store listing, so the title is sized to survive that.
Proper title hierarchy
Title, subtitle, author and series line set in relation to each other rather than stacked and centred.
Series consistency
Ask for book two in the same treatment and the series reads as a set on a shelf.

Book cover sizes for Kindle and print
Each format wants a different frame, and getting the first one right saves redoing the rest:
- Kindle / ebook — 1600 × 2560 px (1:1.6)
- Amazon’s recommended size, and it downsizes cleanly to every thumbnail a store shows. Start here for anything digital.
- Paperback trim — 5 × 8, 5.5 × 8.5 or 6 × 9 in
- The three sizes print-on-demand services quote by default. 6 × 9 is the usual choice for non-fiction, 5 × 8 for genre fiction.
- Spine width — calculated, not guessed
- It depends on page count and paper stock, so your printer’s calculator decides it. This is why the front cover is generated on its own first.
- Audiobook — 3000 × 3000 px (1:1)
- ACX and Audible want a square at least 2400 px; 3000 is the safe recommendation. The front cover artwork recomposes rather than crops.
A print cover also needs a spine and back, whose width depends on page count and paper stock. Generate the front first, then take its artwork into your printer’s cover template — most provide both a calculator and a layout file.
Book cover conventions by genre
Readers navigate stores by visual shorthand, so naming the genre is the most useful thing in the prompt. These are the languages it draws on:
- Thriller & crime
- High contrast, condensed sans-serif set large, a cold palette and one ominous object or silhouette. Restraint reads as menace.
- Romance
- Illustration over photography, warm colour, and a hand-lettered or script title. Cosy sub-genres go brighter and more graphic still.
- Fantasy
- Painted or illustrated scenes, an ornate serif, and often an emblem or symbol that can carry across a whole series.
- Science fiction
- Geometry, cool metallics and wide or technical type. Scale is the recurring idea — something small against something enormous.
- Literary fiction
- Negative space, one striking image and understated type. The cover signals that it trusts the reader.
- Horror
- Near-black grounds, distressed or unsettled type, and a single detail that is slightly wrong rather than openly gory.
- Business & self-help
- One bold graphic idea, a heavy serif or grotesque, and a subtitle that does the explaining so the title can stay short.
Following the convention is not unoriginal; it is how a reader finds you. Be distinctive within the language of the genre rather than outside it.
The thumbnail test
A cover that only works at full size is a cover that will not be clicked. Shrink it to about 200 pixels tall — roughly what a store listing shows — and check that the title is still readable and the image still resolves into something.
If it fails, the fix is almost always fewer elements and a bigger title, not a different picture. Ask for exactly that in a chat refinement.
Book Cover Maker FAQ
Lead with the genre, then add the mood, the palette and one image idea. Put the title and author name in quotes so they are set as typed. Generate at ebook proportions, check it at thumbnail size, and ask in chat for heavier type if the title weakens when small.
1600 × 2560 pixels at a 1:1.6 ratio is Amazon’s recommendation and works across ebook stores.
Four things, in this order: the genre, the mood and palette, one concrete image idea, and the exact title and author text in quotes. Saying where the title should sit — upper third, lower third — is worth adding when the image has an obvious focal point.
No. Nothing is stamped on your export, including on the free plan, so a cover can be uploaded to KDP as it comes.
Yes. Ask for a square version of the same design and it is recomposed to 1:1 at 3000 × 3000 rather than cropped — ACX and Audible require a square of at least 2400 px.
It generates the front cover. For a print wrap, use that artwork inside your printer’s cover template, since spine width depends on your page count and paper.
Covers are composed for small-size legibility, and you can preview at thumbnail scale before exporting. If the title looks weak, ask for heavier type in chat.
Yes. Generate the first cover, then ask for the next book in the same treatment with a new title — the series reads as a set.
Yes — designs you generate are yours to use commercially. Check the current disclosure rules of the store you publish through, as some ask you to declare AI-generated content.
