Apple rejects App Store screenshots that are even one pixel off the required size, which is why “wrong dimensions” is one of the most common upload errors in App Store Connect. This guide lists the sizes developers most often need, explains which ones are required, and shows a fast way to resize without uploading your unreleased UI to a third-party server.
Check the source of truth
Apple updates these tables when new devices ship. Third-party guides, including this one, can lag behind. Confirm the final numbers in the App Store Connect screenshot specifications before you submit. The TinyPixels Screenshot Resizer shows the date its presets were last verified.
Which iPhone screenshot sizes are required?
You do not need a separate set for every iPhone. App Store Connect lets you provide screenshots for the largest display class and scales them down for smaller devices. Third-party guides agree that the 6.9-inch set is the one to design for. Note that Apple's own specification page, as used by the TinyPixels Screenshot Resizer presets, says at least one screenshot is required at the medium Dynamic Island size (1179 × 2556 or 1206 × 2622), so check which slot App Store Connect marks as required for your app. These portrait sizes are accepted for the 6.9-inch class:
| Display class | Portrait size (px) | Notes |
|---|---|---|
| 6.9-inch iPhone | 1320 × 2868 | Native size for the newest large iPhones |
| 6.9-inch iPhone | 1290 × 2796 | Also accepted |
| 6.9-inch iPhone | 1260 × 2736 | Also accepted |
| 6.5-inch iPhone | 1284 × 2778 | Sources disagree on whether this set is still needed when you provide 6.9-inch |
The disagreement about the 6.5-inch set is real: some guides say it is only needed when you skip the 6.9-inch set. Treat App Store Connect as the final word.
iPad screenshot sizes
If your app runs on iPad, you need at least one 13-inch iPad set. The common portrait size is 2064 × 2752 px, and the older 12.9-inch size, 2048 × 2732 px, is also listed. If your app is iPhone-only, skip iPad entirely.
Limits that apply to every device class
- Each device class and localization accepts 1 to 10 screenshots.
- Files must be PNG or JPEG, and Apple screenshots should not contain transparency.
- Landscape sizes are the portrait sizes with width and height swapped.
- Sizes must match exactly. Close is not good enough.
How to fix the “wrong dimensions” error
- Open the screenshot in an editor or the resizer and read its exact pixel size.
- Pick the target size from the table above for the device class App Store Connect is asking about.
- Crop to fill the frame, or pad the image with a background color if you want to keep the whole screenshot.
- Export as PNG or JPEG without transparency, then re-upload.
Resize screenshots without uploading them
Unreleased app UI is exactly the kind of image you may not want on a stranger's server. The free TinyPixels Screenshot Resizer runs entirely in your browser using the Canvas API: pick a device preset, drag to choose the crop, and export one image or a ZIP. Your images never leave your device, and you can confirm that in your browser's network tab.
Once your screenshots are the right size, they are often much larger than they need to be. Compressing the exported PNGs locally with TinyPixels keeps upload times short and your repository light.
Frequently asked questions
What size should App Store screenshots be in 2026?
For iPhone, design for the 6.9-inch display: 1320 × 2868 px in portrait is the native size, and 1290 × 2796 and 1260 × 2736 are also accepted. For iPad apps, provide a 13-inch set at 2064 × 2752 px. Always confirm against App Store Connect.
Do I need screenshots for every iPhone size?
No. App Store Connect scales the largest set you provide down to smaller iPhones, so one correctly sized set is usually enough.
How many screenshots can I upload?
You can upload 1 to 10 screenshots per device class and localization.
Why does App Store Connect say my screenshot has the wrong dimensions?
The pixel size does not exactly match an accepted size for that device class. Even one pixel off triggers the error. Resize or crop to an exact listed size and export without transparency.
Is it safe to upload unreleased app screenshots to online resizers?
It depends on the tool. A resizer that runs in your browser and never uploads images, like the TinyPixels Screenshot Resizer, keeps unreleased UI on your device.
