How to Set a Wallpaper on iPhone, Android, Windows, and Mac

Downloading a wallpaper is the easy half. Setting it so it actually looks right — full frame, no awkward crop, subject not hidden behind the clock — takes a minute of care. The steps below cover the four platforms most Meitukong visitors use. Menu names vary slightly by OS version and phone maker, but the flow is the same on each: download first, then set from your system settings or photo app, not from the browser.

Before you set it: pick the right size

Phone wallpapers on this site are vertical, usually around 941×1672 or 1152×2048, made for a tall phone screen. Desktop wallpapers are horizontal, usually around 2048×1152 or 1672×941. If you set a vertical phone image as a desktop background, the system will crop or stretch it, and the result will look wrong even if the image itself is good. Check the device label and the resolution on the wallpaper's download page before you download — that is the size you are actually getting.

iPhone

  1. Download the wallpaper, then open it in the Photos app.
  2. Tap Share, then Use as Wallpaper (on newer iOS versions, this is under the share sheet's wallpaper option).
  3. Pinch to position the image. Pay attention to where the clock sits: if the subject is centered, it will sit behind the time. Shift it down or to one side if needed.
  4. Tap Set, then choose Lock Screen, Home Screen, or both. Most people want the same image on both, but a busy image works better on the lock screen, where there are fewer icons.

Alternatively, go to Settings > Wallpaper > Add New Wallpaper > Photos, and pick the downloaded image from there. The preview in this flow is the most reliable way to check the crop before committing.

Android

Android varies by maker — Samsung, Pixel, and others label the menus differently — but the usual paths are:

  1. Long-press an empty area of the home screen, tap Wallpaper & style or Wallpapers, then choose the downloaded image.
  2. Or open the image in your gallery app, tap the menu, and choose Set as wallpaper.
  3. Choose Home screen, Lock screen, or both, and confirm the crop. On Android, the home screen wallpaper often scrolls slightly as you swipe between pages; a centered subject survives that better than one at the edge.

Windows

  1. Download the desktop-sized image and save it somewhere you will not delete, such as your Pictures folder.
  2. Open Settings > Personalization > Background.
  3. Under Personalize your background, choose Picture, then Browse photos and select the file.
  4. Under Choose a fit, pick Fill if the image matches your screen ratio (most desktop wallpapers here are 16:9), or Fit if you would rather see the whole image with bars than a crop.

Mac

  1. Download the desktop-sized image and save it to your Pictures folder.
  2. Open System Settings > Wallpaper, then click Add Photo and choose the file — or right-click the image in Finder and choose Set Desktop Picture.
  3. If the image looks cropped, check that you downloaded the desktop size, not the phone size. A vertical image on a wide Mac display will always be a compromise.

If it looks wrong after setting

The usual causes, in order, are: wrong device size (phone image on desktop, or the reverse), the subject sitting behind the clock or a widget, and a thumbnail being set instead of the full file. Fix them in that order before assuming the image itself is bad. And if a wallpaper looked great in the gallery but feels too busy once icons sit on top of it, try it as a lock screen only — lock screens have almost nothing competing with the image. Browse by device from the home gallery to avoid the size mistake in the first place.
