App Store screenshot sizes 2026: the required sizes, every device class, and iPhone Duo

Apple's wording: “To submit your app, you must provide screenshots for the following required display sizes: iPhone: At least one screenshot for iPhone with Dynamic Island (medium display). iPad (if your app supports iPadOS): At least one screenshot for iPad 13-inch display.” The medium Dynamic Island class covers iPhone 14 Pro through iPhone 18 Pro and the iPhone 17.

According to ASOitis's reading of Apple's screenshot specifications on October 11, 2026, the only iPhone size Apple requires is now the Dynamic Island medium display — 1179 × 2556 or 1206 × 2622 pixels — not the 6.9-inch size most cheat sheets still list, and from April 2027 apps built with the iOS 27.1 SDK must add screenshots for both of iPhone Duo's displays.

If your app looks the same everywhere, Apple says “you only need to provide screenshots for the highest required resolution. App Store Connect automatically scales them down for smaller device sizes.” The page's fallback notes are inconsistent — the required medium size isn't the largest class — so if you care how you look on a Pro Max, upload the large Dynamic Island size too rather than trusting scaling.

Apple's specification page now lists iPhone Duo first, with an outer display at 1398 × 2034 and an inner display at 2007 × 2853 pixels (and both rotated), and says: “Starting in April 2027, screenshots will be required for any app using the iOS 27.1 SDK or later.” Apple's iPhone Duo announcement adds that the device is available from October 23, 2026, that you should recompile with Xcode 27.1, and that a new preview tool in App Store Connect shows how your page looks on it.

The inner display is close to a square, so screenshots designed for a tall phone won't simply stretch. Plan a separate layout — and since App Review counts screenshots per device, make sure most of them show the app actually running on Duo.

• Count: at least one and up to 10 screenshots per device size.
• Format: .jpeg, .jpg or .png. Apple: “Images can't include alpha channels or transparencies.”
• Content: Guideline 2.3.3 says screenshots “should show the app in use, and not merely the title art, login page, or splash screen.”
• More than half, per device: Apple's new App Review guidance says it “will approve only those submissions where more than half of screenshots show the app in use.” With three screenshots per device, two must show the app; with four, three.
• One can be enough: the same guidance says one screenshot for a device “is sufficient as long as it shows your app in use”, and one in-app image may span several screenshots.

Captions, frames and backgrounds are fine. What fails is a set that's mostly posters. Our Guideline 2.3 page covers the rest of the metadata rules.

These go beyond in-app visuals, and Apple lets you use them on custom product pages and test them with product page optimization. Search result videos are muted and can't be unmuted, so design them to work without sound.

1. Design at 1320 × 2868 (large Dynamic Island) and export 1206 × 2622 for the required medium class.
2. Add 2064 × 2752 iPad screenshots if your app runs on iPad — and make sure they show the iPad layout, not a stretched phone.
3. Plan iPhone Duo outer and inner layouts before you move to the iOS 27.1 SDK.
4. Keep more than half of each device's screenshots showing the real app; put the headline above the screen, not instead of it.
5. Export JPEG or PNG with no transparency, and recheck Apple's page before each release.
