A book cover has about two seconds to earn a click. On Wattpad, readers scroll through hundreds of stories at once. On Amazon, your cover appears as a thumbnail smaller than a postage stamp, competing against dozens of others on the same screen. If the cover does not communicate genre, mood, and quality in that tiny format, the book gets skipped.
AI image generators have made professional-quality cover art accessible to every author, but the output is only as good as the prompt. A vague prompt like "fantasy book cover" produces something generic and unusable. A specific prompt that describes the subject, mood, color palette, composition, and where to leave space for the title produces something that looks like it came from a professional designer.
Here are 70+ ready-to-use prompts organized by genre. Copy them directly into your AI image tool, customize the details to match your story, and generate cover art that stands out on any platform.
How to Write a Good AI Prompt for Book Covers
Before jumping into the prompt library, a few principles will help you get better results from any prompt in this collection.
Structure Your Prompt Like a Creative Brief
A strong book cover prompt includes five elements:
- Subject. What is the main visual element? A character, an object, a landscape, a symbol.
- Mood and atmosphere. Dark and brooding? Light and whimsical? Warm and romantic? Tense and suspenseful?
- Color palette. Name two to three dominant colors. Genre conventions matter here , romance leans warm (blush, gold, peach), thrillers lean cool and dark (navy, charcoal, crimson).
- Composition. Where should the focal point sit? Where should the title go? Specify "leave clear space at the top for title text" so the AI does not fill the entire frame.
- Style. Photorealistic, illustrated, painterly, minimal, cinematic. The style should match genre expectations.
Always Generate the Art Without Text First
AI image generators struggle with clean typography. Letters come out warped, misspelled, or poorly placed. The best workflow is to generate the cover art as a text-free image, then add your title, subtitle, and author name in a separate design tool like Canva or Photoshop. Every prompt in this collection assumes text-free generation.
Design for Thumbnail Size
Your cover needs to work at full size and at thumbnail size. After generating, shrink the image to roughly 150 x 200 pixels and check whether the main visual element is still clear and the composition still reads. If details disappear at thumbnail scale, simplify the composition and increase contrast.
Match the Platform Specs
- Wattpad: 512 x 800 pixels (recommended). Vertical format. Covers appear in grids and carousels.
- Kindle (KDP): 1600 x 2560 pixels for ebooks. 2:3 or similar vertical ratio.
- Print (paperback): Varies by trim size. Common sizes include 5 x 8 inches and 6 x 9 inches. Add bleed margins.
Generate at the highest resolution your AI tool supports, then resize to the target dimensions. If you need to clean up your source image first, a background removal tool can strip away clutter and give you a clean starting point for compositing cover elements.

What makes a good AI-generated book cover?
A clear focal element that reads at thumbnail size, a color palette that matches genre conventions, clean composition with space for title text, and a mood that signals what kind of story the reader is getting before they read a single word.
Can I use AI-generated covers on self-publishing platforms?
Yes. Amazon KDP, Wattpad, Kobo, and most self-publishing platforms accept AI-generated cover art. Amazon requires you to disclose AI use during the publishing process. The cover must still meet the platform's quality and content standards.
