5.25" × 8" KDP Cover Template & Dimensions

5.25 × 8 in splits the difference between 5 × 8 and the digest size — a favorite for genre fiction, especially romance, mystery and thrillers. The extra quarter inch of width keeps line lengths comfortable at normal font sizes without pushing your book into bigger, more expensive trade-paperback territory.

5.25" × 8"

Full-wrap cover dimensions

Your cover file holds back cover + spine + front cover plus 0.125 in of bleed on each outside edge, so its width depends on page count and paper. For example, at 300 pages on white paper a 5.25" × 8" cover is 11.4256 × 8.25 in. All values below are computed from KDP's formula.
