Best PromptsBook Cover Design
Design a cover that signals its genre and stays readable as a thumbnail, with exact title text and a layout built for retail listings.
Design a book cover. Title, exactly as it should appear: [TITLE] Subtitle: [SUBTITLE, or "none"] Author name as it appears: [NAME] Genre: [THRILLER / LITERARY FICTION / ROMANTASY / BUSINESS NONFICTION / MEMOIR / SCIENCE FICTION / SELF-HELP] What the book is about in one sentence: [PREMISE] The feeling a reader should get in one second: [e.g. "dread", "warmth", "authority"] Comparable titles whose shelf it belongs on: [2-3 BOOKS] Format: [EBOOK ONLY / PAPERBACK / BOTH] Prompt: A [GENRE] book cover, [ORIENTATION: portrait 2:3]. Central image: [THE ONE VISUAL IDEA. One image, not a collage. Prefer a single strong symbol or figure over a literal scene.] Rendered as [PHOTOGRAPHIC / ILLUSTRATED / TYPOGRAPHIC / TEXTURED ABSTRACT], in [PALETTE: 2-3 colors, named], [LIGHTING AND MOOD]. Typography: the title "[TITLE]" is the largest element, set in [TYPE STYLE], [PLACEMENT: upper third / lower third / centered], in [COLOR], with high contrast against what sits behind it. Every letter fully formed and correctly spelled. The author name "[NAME]" is set smaller in [PLACEMENT], in the same type family. [SUBTITLE placement and size, if any.] Composition: clear hierarchy of title, image, author. Generous negative space around the title so it stays legible. No busy background behind any text. Genre signals to include: [e.g. for a thriller: cold palette, hard shadows, a lone figure, a heavy condensed title. For romantasy: illustrated figures, ornate frame, gold accents.] The cover must be recognizable as its genre from the palette and type alone, because that is how a browsing reader sorts a page of thumbnails. Clean flat cover artwork only. No 3D book mockup, no spine, no pages, no hands holding it, no barcode, no publisher logo, no watermark. Then produce three variations: one photographic, one illustrated, one typography-led. Finally, describe how each version reads at thumbnail size (about 100 pixels tall) and which elements survive that.
How to use
Sales are decided by the thumbnail test in the last step, because almost every buying decision happens at a size where only the palette, one shape, and maybe the title survive. Generating three directions rather than iterating on one is worth the extra passes, since covers are a genre-matching problem and the direction matters far more than the execution. Have the final title typeset by hand in a design tool; generated type is close enough to judge a layout and rarely clean enough to publish.
