Book Covers That Sell: Genre Signals, Thumbnails and Print Wraps

A cover’s first job is to tell the right reader "this is for you" at thumbnail size. Learn genre signals, typography, ebook and print specifications, and when to hire a designer.

Key takeaways

  • A cover is marketing, not illustration: it should signal genre and tone to the right reader in a second.
  • Most shoppers first see your cover as a small thumbnail, so test it at that size before you approve it.
  • An ebook needs only a front cover; a paperback needs a full wrap of back, spine and front sized to your page count.
  • Hire a designer when you can, and if you design it yourself, copy the conventions of bestsellers in your category.

Readers do judge books by their covers, and they’re right to. A cover is a promise about what kind of experience is inside. Get the promise right and the right readers click. Get it wrong and even a wonderful book gets scrolled past, or bought by the wrong readers who then leave disappointed reviews.

What Makes a Book Cover Sell?
