Book covers come in different sizes; various factors including the number of pages and the type of paper used are just some factors to consider. But generally, if you’re using Adobe Photoshop to design a book cover, the ideal size is 2,560 × 1,600 pixels.

What are standard book cover sizes? Popular book sizes start at 4.25” by 6.87” and range up to 6” by 9” in size.

If you’re planning to distribute your books to various publishers, you can follow the general sizing rule of keeping your cover image at least 1500 to 1800 pixels wide and stick to 1:1.6 ratio. Which means that if you have an image that’s 1500 pixels wide, multiply that with 1.6 and your image height should be 2400 pixels.

For book covers, that means using three point sizes. One size for the key words of the title (usually 48 or higher), a second size for the author name and subtitle (anywhere from 18-36 points), and a third for blurbs, promos, and descriptive text (usually 10-12 points).
