OnePlus · 2025 · Current model
The OnePlus 13 came out in 2025 with a 6.82-inch screen of 1440 × 3168 pixels: a 19.8:9 aspect ratio at 510 pixels per inch. That is one of the sharpest phone screens made, so a wallpaper needs every one of those pixels to look crisp.
Phones with a QHD+ screen like this one often come set to a lower FHD+ resolution to save battery. Make the wallpaper at the full 1440 × 3168 anyway: the phone scales it down cleanly, and it stays sharp if you switch to full resolution.
Lock screen and home screen
1440 × 3168
The exact size of the screen. Use it for both.
Scrolling home screen
2880 × 3168
Twice the width, only for launchers that slide the wallpaper as you swipe between pages. Most keep it still.

Both screens show the wallpaper at the same size, but different things sit on top of it.
Menu names change a little between software versions. If an option isn't there, open the picture in your gallery app and look for Set as wallpaper in its menu.
1440 × 3168 pixels, the native resolution of its 6.82-inch screen. Use the same size for the lock screen and the home screen.
19.8:9. The screen is 1440 pixels wide and 3168 pixels tall, so an image with a different shape is cropped at the edges when you set it.
Yes. A 4K portrait image (2160 × 3840) has more pixels than the OnePlus 13 shows, so it stays sharp, but its 16:9 shape doesn't match the 19.8:9 screen, so part of it is cropped. Fit it to 1440 × 3168 first to choose what stays.
Usually the image is smaller than 1440 × 3168 or a different shape, so the phone enlarges it to fill the screen. Make it at the exact size with the tool on this page, and start from the original photo, not a screenshot or a copy sent through a chat app.
Usually not. Most launchers keep the wallpaper still, so 1440 × 3168 fills it exactly. If yours slides the wallpaper as you swipe between pages, use 2880 × 3168 instead.
