iPhone Duo wallpaper size
The iPhone Duo has two screens, so it takes two wallpaper sizes. The inner display is 2670 × 1878 pixels, landscape when the phone is open, at 430 ppi behind a nano-texture finish. The outer display is 1398 × 2034 pixels, portrait, at 460 ppi. Both are read from Apple's iPhone Duo tech specs on 10 September 2026.
Make the pair. One image in, both files out, with each screen's clock and camera drawn where Apple's own images put them. Preview it open, folded like a book and closed. Nothing is uploaded.

| Display | Wallpaper size | Held | Density | Active area |
|---|---|---|---|---|
| Inner7.6-inch folding OLED, nano-texture finish | 2670 × 1878 | landscape | 430 ppi | 157.7 × 110.9 mm |
| Outer5.4-inch OLED | 1398 × 2034 | portrait | 460 ppi | 77.2 × 112.3 mm |
Active area is our arithmetic on Apple's figures: pixels divided by pixels per inch. It agrees with Apple's own rectangle diagonals of 7.58 and 5.36 inches.
At the same physical size, the outer display covers 48.9 % of the open picture's width and needs 1.2 % more than its full height, on a panel 7 % denser. So one file cannot fill both screens pixel for pixel. The studio gives the outer its own window on the same picture, at the same scale and centred on the same point, and a slider moves that window between the left and right half.
The hinge runs down the middle of the inner canvas, at x = 1335. Apple says its adhesives minimise the crease; the studio still draws the line as a guide, for anyone who folds and unfolds often and would rather keep a face off it.
Six pairs to start from.
Drawn by this site's generator and stored as the inner canvas; the outer is taken from each one the way the studio takes it from any image. Free to use, like everything the generator makes.
Night Sky and Star White are the names of two palettes made for these samples, after the colours the Duo comes in. The pictures are the generator's own; no Apple image is used or copied.

Orientation
Apple prints the inner display as 1878 by 2670 and the outer as 1398 by 2034. The order of those numbers does not say which way up a screen is, so orientation comes from Apple's body dimensions instead. Open, the phone is 164.6 mm wide and 117.8 mm tall, which makes the inner canvas 2670 wide by 1878 tall. Closed, it is 84.1 mm by 117.8 mm, so the outer canvas is portrait.
Safe zones
The clock, date, camera and buttons in the studio's previews are placed from Apple's straight-on product images of each lock screen, as fractions of the screen. They are approximate.

Questions
What size is an iPhone Duo wallpaper?
Two sizes, one for each display: 2670 × 1878 pixels for the inner display and 1398 × 2034 pixels for the outer display. The pair studio exports both from one image.
Is the iPhone Duo's inner display portrait or landscape?
Landscape when the phone is open. Apple's open body is 164.6 mm wide and 117.8 mm tall, so the 2670-pixel side runs across. Apple's photos also show the open phone turned upright, lock screen included. How iOS 27 re-frames a wallpaper when you turn it is not published yet, so keep the subject near the middle.
Can one wallpaper cover both iPhone Duo displays?
Apple has not said whether iOS uses one wallpaper for both displays or one for each. The studio makes both sizes from one image. Set each file on its display, and if iOS lets one image cover both, use the inner file.
Do iPhone 18 Pro wallpapers need a new size?
No. iPhone 18 Pro is 1206 × 2622 and iPhone 18 Pro Max is 1320 × 2868, the same pixel grids as the 17 Pro and 17 Pro Max, so every 17 Pro wallpaper fits pixel for pixel. Both rows are on the size chart.
