The practical answer

What should you ship in 2026?

For a modern universal iOS app, start with one accepted 6.9-inch iPhone set and one accepted 13-inch iPad set. App Store Connect scales these down for smaller displays.

iPhone · primary

1320 × 2868

Also accepted: 1290 × 2796 or 1260 × 2736. Landscape uses the reversed dimensions.

iPad · when supported

13-inch display

2064 × 2752

Apple also accepts 2048 × 2732. Landscape uses the reversed dimensions.
