7 Book Cover Design Tips That Sell More Copies

Your cover is the most important piece of marketing you will ever create for your book. It is the first thing a reader sees, the reason they click, and often the reason they buy. Here are seven principles we apply to every cover we design at Scriptly.

1. Readable at Thumbnail Size

Online, 90% of the time your cover is seen as a small thumbnail on a phone screen. If the title is unreadable at that size, you have already lost the sale. Test every design at thumbnail scale before you commit.

2. One Idea, Not a Collage

The best covers communicate a single, powerful idea. When a cover tries to show three things at once, it communicates nothing. Strip it down until only the essential remains.

3. Genre-appropriate Typography

Fonts carry meaning. A thriller should not look like a romance, and a literary memoir should not look like a business book. Match your typography to the expectations of your genre's readers.

4. Contrast for Shelf Presence

Your cover must stand out against its neighbors. High contrast between the background and the title — and a distinct color story — helps your book get noticed in both physical stores and digital storefronts.

5. Quality Artwork That's Actually Yours

Stock imagery used by a hundred other authors will make your book blend in. Original illustrations or custom-designed covers build a visual identity readers remember.

Original art isn't a luxury. It's a competitive advantage.

6. A Spine and Back Cover That Finish the Job

Many authors obsess over the front and forget the spine and back cover. The back cover copy sells the book once the reader picks it up. Treat it as a mini sales page: hook, benefits, and a clear call to action.

7. Consistency Across Formats

Your paperback, eBook, and hardcover covers should be recognizably the same design family. Consistency builds brand recognition — readers who loved one of your books should recognize your next one instantly.

The Design Process That Works

At Scriptly, cover design is iterative and collaborative. We start with your vision, explore directions, and refine until you're satisfied — with unlimited revisions until it's right.

Your cover is an investment. Getting it right is the difference between a book people scroll past and a book people pick up.
