Recent changes on Apple’s side

The screenshot specifications page carries Apple’s date of 15 October 2026; we last checked it against this data on 19 October 2026.

• 6 to 8 October 2026Apple rewrote its screenshot page. The mandatory iPhone set is now spelled out as “At least one screenshot for iPhone with Dynamic Island (medium display)”, which means the 6.3-inch slot (1206 × 2622 or 1179 × 2556); before, a 6.9-inch set was enough alone. Other points: the 6.5-inch slot still reads “Required if app runs on iPhone and screenshots for iPhone with Dynamic Island (large display) aren’t provided”, and slots no longer go by their diagonal (the 6.9-inch one became “iPhone with Dynamic Island (large display)”). Fallbacks moved as well: the 6.1-inch slot now draws on the 6.3-inch set, while the 6.9 and 6.5-inch slots draw on each other. For the iPhone Duo, Apple writes: “Starting in April 2027, screenshots will be required for any app using the iOS 27.1 SDK or later.” None of the accepted sizes moved. The Web Archive already holds the new page in its 6 October copy, and the live version carries 8 October.
• By 16 September 2026The iPhone 18 Pro Max (6.9-inch slot) and iPhone 18 Pro (6.3-inch) show up on Apple’s page, along with a brand-new iPhone Duo slot: 1398 × 2034 for the outer screen and 2007 × 2853 for the inner one, uploads being “available later this year”. Two Apple Watch lines gained a name: 422 × 514 now lists the Ultra 4, and 416 × 496 the Series 12. Web Archive snapshots bracket the change, since the 30 July copy has none of it and the 16 September copy has all of it. That version itself carried the date 17 September.
• 9 September 2026Apple dropped the table of device screen sizes from the Layout page of the Human Interface Guidelines. For that reason the geometry here is taken from Xcode’s device profiles and from the Simulator.

Where the figures come from

• Sizes, requirements, fallbacks and the lists of devices per slot come from App Store Connect Help, Screenshot specifications (Apple’s date: 15 October 2026). On 19 October 2026 each slot here was checked against that page in both directions: every size we show appears on Apple’s page under the same slot and label, and every size Apple shows appears here.
• App previews follow App preview specifications, checked in the same way. The line saying you “only need to provide screenshots for the highest required resolution” sits in the Display scaling section of Screenshot specifications. The former Upload app previews and screenshots page now redirects to Manage your App Store assets.
• Panel pixels, scale, corner radius and the Dynamic Island come from the device profiles inside Xcode 27.0 (27A266a). Pixel density is Apple’s own figure whenever a specification page gives one; the Simulator’s value can differ from the real phone, as with the iPhone 8 Plus (326 ppi there, 401 on its specification).
• Points, native scale, safe areas and status bar height were measured with a single-screen probe app in the iOS 27.0 Simulator on 28 September 2026. A model that was never booted borrows the reading of another one, and its card says which: one with an identical screen or, for some iPads, a different iPad (in iPadOS 27 every iPad measured returned the same insets). iOS 27 does not run on the iPhone 8, 8 Plus, X, XS, XS Max or XR. All of them but the 8 Plus show the reading of a newer iPhone with the same screen; the 8 Plus has no such twin and is flagged as not measurable. Xcode 27.0 includes no iPhone Duo.
• Sanity check: the Simulator’s iPhone 16 reports a 59 pt top safe area, a 54 pt status bar and a 34 pt bottom inset, which matches our pixel measurement of a real screenshot.
• Simulator captures: xcrun simctl io produces the correct pixel size, but as a PNG with an alpha channel, on all 18 devices we tried. Running sips -s format jpeg -s formatOptions 95 in.png --out out.jpg keeps the dimensions and drops the alpha.

Reuse: go ahead and reuse these figures as long as you credit Flexdger Wallet. The complete table is also published as data in screenshot-sizes.json, with a source attached to each value.
