Quick answer: to submit an iPhone app today, App Store Connect requires at least one screenshot for iPhone with Dynamic Island (medium display). The accepted portrait sizes are 1206 × 2622 and 1179 × 2556. iPhone Duo (Apple's foldable iPhone) uses a separate slot: 1398 × 2034 for the outer display and 2007 × 2853 for the inner display.
All pixel counts below come from Apple's screenshot specifications, checked on November 11, 2026. Landscape sizes are the same numbers swapped. A longer table, including iPad, Mac, Apple TV, Vision Pro and Watch, is on the canonical guide.
The required iPhone size: 1206 × 2622
Apple's required iPhone slot is iPhone with Dynamic Island (medium display). It is not labelled "6.3 inch" on the specifications page.
| Slot | Portrait | Landscape |
|---|---|---|
| iPhone with Dynamic Island (medium display), required | 1206 × 2622 or 1179 × 2556 | 2622 × 1206 or 2556 × 1179 |
If you also want the large display Dynamic Island slot (optional today), Apple accepts 1260 × 2736, 1290 × 2796 and 1320 × 2868, plus the swapped landscape sizes. If that slot is empty, App Store Connect uses scaled screenshots from iPhone with Face ID (large display).
A file that is one pixel off is refused. 1206 × 2622 is not a substitute for the Duo sizes below: the aspect ratios are different.
iPhone Duo sizes: 1398 × 2034 and 2007 × 2853
iPhone Duo has two displays. App Store Connect lists both families of sizes in a single iPhone Duo slot.
| Display | Portrait | Landscape |
|---|---|---|
| Outer display | 1398 × 2034 | 2034 × 1398 |
| Inner display | 2007 × 2853 | 2853 × 2007 |
Apple's specifications page says that, starting in April 2027, iPhone Duo screenshots will be required for any app using the iOS 27.1 SDK or later. The 5 October 2026 developer news post words it as: starting April 2027, apps and games submitted will need to include iPhone Duo screenshots. Those are two formulations of the same date; read both before you plan around the deadline. When you submit iPhone Duo screenshots, the product page shows a badge that the app is made for iPhone Duo.
The specifications page lists both displays. It does not say that one display replaces the other. Stick to the sizes Apple lists, and keep important text and controls away from the inner-display fold.
File rules that usually cause a rejection
From the same Apple page:
- Files must be
.png,.jpgor.jpeg. - "Images can't include alpha channels or transparencies." A PNG that still has an alpha channel is refused even when it looks opaque.
- Dimensions must match an accepted size exactly.
- You can upload up to 10 screenshots per device size.
Guideline 2.3.3 still applies: screenshots should show the app in use. That is a review rule, not a dimensions error.
Common mistakes
- Uploading a 1320 × 2868 or 1398 × 2034 file into the required medium display slot, or the reverse.
- Stretching a 1206 × 2622 capture to fill 1398 × 2034 or 2007 × 2853. The ratios are not the same (~0.46 vs ~0.69 and ~0.70). A recrop only works if the subject still fits; otherwise shoot again.
- Leaving portrait and landscape swapped.
- Exporting a PNG with transparency still on.
FAQ
Is 1206 × 2622 mandatory?
It is one of the two accepted sizes in the slot that is mandatory for iPhone apps today. The other accepted size in that same slot is 1179 × 2556.
What is the iPhone Duo screenshot size?
There are two: 1398 × 2034 (outer) and 2007 × 2853 (inner) in portrait, or 2034 × 1398 and 2853 × 2007 in landscape.
Are iPhone Duo screenshots required today?
The specifications page ties the requirement to April 2027, for apps using the iOS 27.1 SDK or later. See also Apple's 5 October 2026 note, cited above.
How many screenshots can I upload?
Up to 10 per device size.
I build DuoShot, a browser tool that checks your real app captures and exports a ZIP at the App Store Connect sizes, including 1206 × 2622 and the two iPhone Duo sizes. It does not upload files to App Store Connect; you add them to your listing yourself. A size match does not guarantee Apple approval.
