Cover Design Pro Tips
| Tip | Detail |
|---|---|
| Think thumbnail first | Your cover must be recognizable at 200×300px on Amazon search. Test small. |
| One dominant element | Strong covers have ONE hero visual — don't crowd the composition |
| Genre signals | Readers scan covers for genre cues in seconds. Stay within genre conventions |
| Color contrast | Title text must be legible — generate covers with clear areas for text |
| Series consistency | For a series, use the same model + similar prompt structure for cohesion |
| No watermarks | Always generate at highest quality; mention "no watermark, no text" in prompt |
Common Mistakes
| Mistake | Fix |
|---|---|
| Generating text directly in AI | AI-generated text is unreadable. Generate image only, add text in Canva |
| Too complex composition | Simplify — one focal point, not five |
| Wrong genre signals | A romance cover shouldn't look like a thriller. Research your genre first |
| Low contrast colors | Check title readability at thumbnail size before exporting |
| Skipping the spine/back | For print books, use KDP cover calculator; AI handles front only |
