App Store Screenshot Sizesとは？

Apple requires different screenshot dimensions for each supported device display size. For iPhones, the required sizes are: iPhone 6.9-inch (1320x2868 pixels), iPhone 6.7-inch (1290x2796 pixels), iPhone 6.5-inch (1242x2688 pixels), and iPhone 5.5-inch (1242x2208 pixels). For iPads, the required sizes are: iPad Pro 12.9-inch (2048x2732 pixels) and iPad Pro 11-inch (1668x2388 pixels). These dimensions are for portrait orientation. Landscape screenshots use the same values with width and height swapped.

You can upload up to 10 screenshots per localization per device size. The minimum requirement is to provide screenshots for the largest iPhone display size (6.9-inch or 6.7-inch), which App Store Connect can scale down for smaller devices. However, providing optimized screenshots for each size ensures the best visual quality across all devices. Screenshots must be in PNG or JPEG format with no transparency.

When designing your screenshots, keep in mind that the first three frames appear in search results and carry the most conversion weight. Design at the largest required resolution first, then adapt for smaller sizes. If your screenshot designs use device frames, make sure the mockup matches the target device size. ScreenMagic handles all these size requirements automatically, generating correctly sized assets for every Apple device in seconds.
