Use enough pixels. Keep the book’s intended shape.
A 1:1.6 ratio such as 1600 × 2560 px is a useful general-purpose starting point. A 2:3 ratio such as 1800 × 2700 px is also common for trade-book designs.
Store requirements change, so confirm the current rules of your publishing platform. For an EPUB already in use, matching the existing cover dimensions is often the least disruptive choice.
