Apple organizes screenshot requirements by device display size, and each size accepts specific pixel dimensions. The key tiers for iPhone are:
- 6.9-inch (iPhone Air and Pro Max and Plus models since iPhone 14 Pro Max) — 1320 × 2868, 1290 × 2796 or 1260 × 2736 px
- 6.5-inch (iPhone 14 Plus, 13 Pro Max, 11) — 1284 × 2778 or 1242 × 2688 px
- 6.3-inch (iPhone 17, 16 Pro, 15 Pro) — 1206 × 2622 or 1179 × 2556 px
- 5.5-inch (legacy, iPhone 8 Plus) — 1242 × 2208 px
An iPhone app needs 6.9-inch screenshots, or 6.5-inch ones if 6.9-inch aren't provided. App Store Connect scales them for the smaller iPhone sizes, so the other tiers are optional.
