Accepted App Store screenshot sizes
Apple now requires a 6.9″ iPhone and a 13″ iPad screenshot at minimum — App Store Connect scales those down to fit smaller devices. The sizes below are all accepted (portrait dimensions shown; the landscape orientation is the same numbers swapped).

Why screenshot dimensions matter
App Store Connect rejects screenshot uploads whose pixel dimensions don't exactly match one of Apple's accepted sizes. A screenshot that's even a pixel off — often the result of a status bar, a scaled simulator capture, or an exported mockup — will fail to upload and block your submission. Validating dimensions before you open App Store Connect saves a frustrating round trip.
What this validator checks
- Exact pixel dimensions against every accepted iPhone and iPad size
- Portrait and landscape orientations (Apple accepts either)
- Whether each size is one of Apple's currently required dimensions
- File format is PNG or JPEG, the only types the App Store accepts
