How to set a wallpaper on an Android phone

Android lets you set the wallpaper in several ways, and the exact menu names depend on the phone maker. This guide covers Android 16 on Pixel phones and One UI on Samsung Galaxy phones, which together account for most devices. If your phone is from another brand, long-pressing an empty spot on the home screen almost always opens the wallpaper settings.

Choose a tall picture

Phone screens today are usually around 9:19.5 or 9:20. On WallpaperDuck the phone pictures are 1776 × 3840 pixels in that proportion, so they fill the screen without cropping. Landscape pictures work too, but Android has to crop them, and you will only see a vertical slice. Use the tall aspect filter on the home page, or open a topic like /wallpapers/nature or /wallpapers/space and pick the portrait frames.

Download the file

Open the wallpaper in Chrome and use the download button on its page.
Choose the JPEG at the size you want. For a phone, 1920 pixels on the long edge is already enough; the full-size file simply takes more storage.
The picture lands in Downloads and appears in Google Photos or Gallery within a few seconds.

On a Pixel (Android 16)

Open Settings, or touch and hold an empty area of the home screen, then tap Wallpaper and style.
Tap Change wallpaper. At the top, choose the Lock screen or Home screen tab for the screen you want to change.
Tap Choose a photo and select the downloaded picture.
Check the preview to see where the clock and icons will fall, then tap Apply. Repeat with the other tab if you want a picture on the second screen too.

On a Samsung Galaxy (One UI)

Touch and hold an empty area of the home screen and tap Wallpapers. On newer One UI versions the entry is called Wallpaper and style, followed by Change wallpapers.
Choose Gallery to browse your own photos, and pick the file.
Tap Done, then choose whether to set it on the Home screen, the Lock screen or both.
Newer versions can also tint system colours to match the wallpaper; look in the same menu.

Set it from the Gallery or Photos app

On a Samsung Galaxy you can open the picture in Gallery, tap More options and choose Set as wallpaper. Other gallery apps, including Google Photos, usually offer a similar option in the picture's menu, but the wording varies by phone and app version. The same chooser appears, with the lock screen, home screen or both.

Tips

Themed icons: on Android 13 and later with themed icons turned on, the colours of icons and system panels follow the wallpaper. Pictures with one strong colour give the most cohesive result.
Dark wallpapers on OLED screens use less power, because black pixels are switched off. The dark topic page at /wallpapers/dark is a good starting point.
Scrolling home screen: some launchers scroll the wallpaper sideways as you swipe between pages. If your picture looks cropped, turn this off in the launcher settings, or choose a picture with room on both sides.
Lock screen clock: the clock sits near the top, so choose a picture with calm space there and it stays readable.
