App Store Screenshot Dimensions이란?

Apple defines screenshot dimensions per device display class. The current requirements for portrait screenshots are: iPhone 6.9-inch at 1320x2868, iPhone 6.7-inch at 1290x2796, iPhone 6.5-inch at 1242x2688, iPhone 5.5-inch at 1242x2208, iPad Pro 12.9-inch at 2048x2732, and iPad Pro 11-inch at 1668x2388. For landscape orientation, simply swap the width and height values. These dimensions correspond to the native screen resolutions of each device class at their respective scale factors.

Understanding these dimensions matters because App Store Connect performs strict validation on uploads. If your screenshot is even one pixel off from the required dimensions, the upload will fail. This is different from Google Play, which accepts a range of sizes. When working with design tools, always set your canvas to the exact required dimensions before you start designing. Avoid resizing after the fact, as this can introduce compression artifacts or slight dimension mismatches.

A practical approach is to design a master layout at the largest iPhone dimension (1320x2868 for the 6.9-inch), then create adapted versions for each smaller size. Elements like text size, padding, and device frames may need adjustment at each dimension to look correct. For iPad screenshots, the wider aspect ratio means your layout will differ significantly from phone screenshots. Many developers create separate iPad designs rather than simply stretching their phone layouts. ScreenMagic generates pixel-perfect screenshots at every required dimension, eliminating the manual resizing process entirely.
