Examples to make your own
Your idea
A mystery novel for adults: a brass key on a dark blue desk. Reserve the top for the title.
A more useful prompt
Illustrated front-cover artwork, portrait 2:3. One brass key on a dark blue desk forms the focal point of an adult mystery. Use restrained directional light and leave the upper area uncluttered for a title overlay; reserve a small author area below. Do not add a detective, clues or award badges. Add typography separately.
Your idea
A beginner gardening guide with a terracotta pot and a small green seedling.
A more useful prompt
Illustrated 2:3 front-cover concept for a beginner gardening guide. Center one terracotta pot containing a small green seedling against a calm cream background. Keep the upper title area and lower author area clear. Emphasize approachable shapes and readable contrast, with no harvest promises or extra tools.
Plan the visual
Start with the book’s genre and one visual symbol. A clear focal subject helps the cover remain readable as a small bookstore thumbnail; avoid illustrating every plot point.
Prepare the final artwork
This tool plans front-cover artwork in 2:3. Add the exact title and author in a layout editor, then set your actual trim, bleed and spine measurements for the chosen printing service.
