App Store screenshot sizes — and how to make them on Windows.
Apple wants App Store screenshots at exact pixel sizes per device. Here are the dimensions, why they matter, and how to produce them on Windows without a Mac.
Why App Store screenshots have fixed sizes
The App Store renders your screenshots inside device frames, so Apple asks for exact pixel dimensions per device class. Upload the wrong size and it's rejected or rescaled badly. The job, every release, is to produce one polished screenshot and then output it at each required size — which is where it usually turns into a manual resizing machine.
The sizes (iPhone, iPad, Mac)
These are the App Store / Mac presets ShotsGlow ships as one-click sizes, in exact pixels:
- iPhone 6.5″ — 1284 × 2778 px (portrait), 2778 × 1284 px (landscape)
- iPhone 5.5″ — 1242 × 2208 px (portrait), 2208 × 1242 px (landscape)
- iPad 12.9″ — 2048 × 2732 px (portrait), 2732 × 2048 px (landscape)
- Mac — 2880 × 1800 px
Apple updates its requirements as new devices ship (the latest iPhones use larger 6.9″ and 6.7″ displays), and it generally lets one larger iPhone set stand in for smaller devices. Treat Apple's App Store Connect screenshot specifications as the source of truth and confirm the current list before you submit.
How to make them on Windows — without a Mac
You don't need a Mac to ship App Store screenshots. The trick is to design one master screenshot, then reframe it to each required size instead of rebuilding it by hand:
- Capture your app screen natively on Windows
- Add a designed backdrop, a shadow and any callouts
- Pick an App Store preset — it reframes to the exact pixels
- Export, switch preset, export again — or batch the set
ShotsGlow ships the presets above plus custom sizes for anything new, does it all on-device, and keeps your unreleased UI off other people's servers. See App Store screenshots on Windows for the full workflow.
