Aspect Ratio CalculatorEvery platform crops or letterboxes images that do not match its shape, so the safest workflow is to crop to the right ratio first and then scale to the recommended size.
Apps change their layouts from time to time. The sizes below are the long-standing recommendations, and each page explains where the app draws buttons or text over your picture.
