A well-designed book cover does more than look good—it tells a story at a glance. It should reflect the genre, mood, and key themes of the book while standing out both on shelves and as a thumbnail online. Strong covers use hierarchy in typography, thoughtful color schemes, and compelling imagery. Balance between visual elements and white space is crucial. The title must be legible, and the design should evoke curiosity. Whether created by a professional designer or through DIY tools like Canva, a successful book cover aligns with market expectations and sparks immediate interest from readers.
