iPhone Duo wallpaper size for the cover and inner screens
iPhone Duo has two screens with different wallpaper sizes. The 5.4-inch cover screen is 1398 × 2034 pixels. The 7.6-inch inner screen is 2670 × 1878 pixels when you open the phone, wider than it is tall, and 1878 × 2670 when you turn it upright.

The two screens
Closed, iPhone Duo is a regular-looking iPhone with a 5.4-inch cover screen (5.36 inches measured as a rectangle). Open it like a book and the 7.6-inch inner screen (7.58 inches as a rectangle) unfolds into a wide display, about 50% larger than iPhone 18 Pro Max's. Both are OLED Super Retina XDR screens with ProMotion up to 120Hz and an Always-On display.
One picture on both screens
The cover screen held upright and the inner screen turned upright are nearly the same shape: 1.45 and 1.42 times as tall as they are wide. A picture made for one fills the other with only about 2% trimmed from its height. Opened flat and held sideways, though, the inner screen is wide, and a tall phone wallpaper shows only about half its height there, the same way a phone picture is cropped on an iPad in landscape.
Which size to download
Every iPhone wallpaper on this site comes in both iPhone Duo sizes, cut from the full-resolution original:
- Cover screen, 1398 × 2034: pick iPhone Duo cover screen on any wallpaper page.
- Inner screen, 1878 × 2670: pick iPhone Duo inner screen. It fills the inner screen held upright, and works on the cover screen too.
For the inner screen open and held sideways, a landscape picture suits it better. Apple's own iPhone Duo wallpapers come as separate files for the two screens, with the inner one at 2670 × 1878. Our iPad wallpapers are square, so they fill the inner screen whichever way you hold it.
Picking a wallpaper for iPhone Duo
- Keep the subject in the centre. The middle of the picture is the part that shows on both screens and in both directions.
- Choose calm edges. Gradients, skies, landscapes and abstract designs lose nothing important when the inner screen trims the top and bottom.
- Go dark for the Always-On display. Both screens are OLED, where black pixels are switched off, so a dark wallpaper looks deep and keeps the dimmed Lock Screen calm. See our black wallpapers.
- Set it as usual. Open Settings › Wallpaper › Add New Wallpaper, choose Photos and pick your picture, as on any iPhone. Our guide to setting a wallpaper on iPhone covers each step.

Common questions
What is the iPhone Duo wallpaper size?
The cover screen is 1398 × 2034 pixels (5.4-inch, 460 ppi). The inner screen is 2670 × 1878 pixels when the phone is open, wider than it is tall, and 1878 × 2670 when you turn it upright (7.6-inch, 430 ppi).
Can one wallpaper fit both iPhone Duo screens?
Yes, with a little cropping. The cover screen held upright and the inner screen turned upright are almost the same shape, so a picture made for one loses only about 2% of its height on the other. Opened flat and held sideways, the inner screen is wide, so a tall picture shows only about half of its height there.
Is the iPhone Duo inner screen square?
No. It is about 1.42 times as wide as it is tall when open, close to the shape of a 4:3 photo, so it needs a wider wallpaper than a regular iPhone.
When did iPhone Duo come out?
Apple announced iPhone Duo on 9 September 2026, opened pre-orders on 16 October and put it on sale on 23 October 2026, from $1,999 with 256GB of storage.
