Use --ar 2:3 for standard portrait book covers, which is the industry-standard ratio used by most print-on-demand platforms including Amazon KDP. If you are designing an audiobook cover for Audible or Spotify, use --ar 1:1. Always generate at --ar 2:3 first and adapt for other formats.
Yes, if you are on a paid Midjourney plan, you have the commercial rights to use the images you generate. However, images of people generated by AI are not protected by model releases, so for high-volume selling you may want to avoid covers featuring recognizable human faces to keep things legally clean.
Research the top 10 bestselling covers in your genre on Amazon and identify the common visual patterns, colors, and moods. Then translate those patterns into your prompt. For example, romance covers typically use warm golden light, couples in emotional proximity, and blurred backgrounds, all of which you can specify directly.
Midjourney V8.1 sometimes generates decorative text-like elements or watermarks. Add "--no text, --no watermark, --no letters" to your negative prompt space, or use the Vary option to regenerate the image. Plan to add all real title and author text yourself in a design tool like Canva or Photoshop.
Plan to generate at least 20 to 40 variations before settling on a direction. Use the initial four-image grid to find promising compositions, then use the U (Upscale) and V (Vary) buttons to explore refinements. The best professional workflow treats the first batch as a rough draft, not a final output.
