ScreenlyyiPhone Duo screenshot size
iPhone Duo has two App Store screenshot sizes: 2007 × 2853 pixels for the 7.6-inch inner display (2853 × 2007 in landscape) and 1398 × 2034 for the 5.4-inch outer display (2034 × 1398 in landscape).
From April 2027 they're required for apps built with the iOS 27.1 SDK or later. Apps that provide them get a badge on their App Store product page saying they're optimized for iPhone Duo.

About iPhone Duo
iPhone Duo is Apple's first foldable iPhone, announced on 9 September 2026. It opens like a book: closed, you use the 5.4-inch outer display; open, the 7.6-inch inner display. Apple says the two displays share the same aspect ratio. The inner display has more room, so it's the place to show layouts that use it: a sidebar beside content, two panes side by side, or more of a list at once.
Making them in Screenlyy
Screenlyy has a row for each iPhone Duo display, drawn with a 3D model at Apple's published dimensions. It exports both sizes above, in their own folders. The open Duo can be posed flat, half open like a book, as a tabletop, or closed, and can show a different screenshot on each half.
