Screenshot dimensions

What are App Store screenshot dimensions?

Screenshot dimensions are the per-device-family pixel sizes Apple accepts in App Store Connect. Each iPhone and iPad family lists several accepted sizes rather than one mandatory size, and any of them passes upload; for Apple Watch it lists six sizes and you pick one. A size that appears on no list for its family is rejected outright.

The current 2026 accepted dimensions, per Apple's developer documentation:

- iPhone 6.9-inch (iPhone Air, 17 Pro Max, 16 Pro Max, 16 Plus, 15 Pro Max): 1320 x 2868, 1290 x 2796, or 1260 x 2736 portrait, landscape being the same pairs swapped - iPhone 6.3-inch (iPhone 17 Pro, 17, 16 Pro, 16, 15 Pro, 14 Pro): 1206 x 2622 or 1179 x 2556 portrait - iPhone 6.5-inch (legacy): 1284 x 2778 or 1242 x 2688 portrait - iPad Pro 13-inch (M4): 2064 x 2752 portrait, 2752 x 2064 landscape - iPad Pro 12.9-inch (legacy): 2048 x 2732 portrait - Apple Watch: one of six accepted sizes from 312 x 390 to 422 x 514 portrait (410 x 502 is Ultra 2 and Ultra)

How does Apple's auto-scaling work?

Apple can auto-fill smaller device-family slots from larger uploads. If you upload only the 6.9-inch screenshots, Apple downscales them to fill the 6.7-inch, 6.5-inch, and 5.5-inch slots. The same applies for iPad: a 13-inch upload fills the 12.9-inch slot.

Apple Watch is the exception. The iPhone and iPad rows of Apple's specification each spell out a scaling fallback for the sizes you skip; the Apple Watch row states none, so the watch canvas you upload is the one that ships.

In practice, the auto-scaling produces minor pixel-rounding artifacts. Most production teams upload at least the two largest sizes per family (6.9-inch iPhone and 13-inch iPad) and let auto-scaling handle the rest.

When do screenshot dimensions matter most?

The dimensions are a hard upload gate, but the gate is a list and not a single number: a size on its family's list passes, and a size on no list is rejected. The common mistake is treating the largest size as mandatory and concluding that a smaller accepted size will bounce. Beyond the gate, the size you build at affects how text renders: a caption headline that reads cleanly at 1320 x 2868 may compress awkwardly at the 5.5-inch downscale. Design teams typically build at the largest size their family accepts and verify legibility at the smallest auto-scaled output.
