iPhone Duo screen specs

The single reference page for designing, developing and making wallpapers for the iPhone Duo. Resolutions and sizes are from Apple's official tech specs.

Displays

DisplaySizeAspect ratioNative resolution
Inner display (unfolded) 7.6″ ~7:10 1878×2670 (portrait) / 2670×1878 (landscape)
Cover display 5.4″ ~11:16 1398×2034

The crease & safe area

Book-style foldables have a center fold zone where fine detail and high-contrast edges look distorted at an angle. Apple hasn't documented an official safe area, so we recommend keeping critical content out of the central 6% of the inner display's long side — our wallpaper generator overlays this zone live on your image.

CSS media queries (estimates — CSS sizes not published by Apple)

For web developers who want fold-ready layouts on day one:

/* Cover screen — behaves like a regular tall phone */
@media (max-width: 480px) and (orientation: portrait) { /* ... */ }

/* Inner screen unfolded — tablet-shaped, closer to a small iPad */
@media (min-width: 600px) and (max-width: 900px) and (min-aspect-ratio: 2/3) and (max-aspect-ratio: 3/4) {
  /* two-column layouts work here */
}

/* Apple hasn't published CSS point sizes or a web fold API for the iPhone Duo;
   on the web, watch the CSS Viewport Segments / Device Posture APIs */
@media (horizontal-viewport-segments: 2) { /* spanned across the fold */ }
