App Store screenshot sizes

Apple accepts a few exact sizes per device class — not just an aspect ratio — and scales eligible sets down to smaller iPhones. You can upload 1–10 screenshots per size, as JPEG or PNG with no transparency.

Device classAccepted portrait sizes (px)Required?
iPhone 6.9-inch1320 × 2868, 1290 × 2796, or 1260 × 2736Yes, unless you provide a 6.5-inch set
iPhone 6.5-inch1284 × 2778 or 1242 × 2688Yes, if no 6.9-inch set is provided
iPhone 6.1-inch1206 × 2622 or 1179 × 2556Scaled from a larger set if missing
iPad 13-inch2064 × 2752 or 2048 × 2732Yes, if your app runs on iPad

Landscape versions are the same numbers swapped. Apple adds sizes with new devices, so always check the required wells in App Store Connect's Media Manager before your final export.
