Quick answer

For most modern phones, start with a high-quality portrait image that is at least 1080 pixels wide. A 1080 × 2400 image works well for many Android phones, while iPhone models vary by screen. The safest method is to choose a tall image and preview the crop before applying it.

Why one size does not fit every phone

Phone screens use different aspect ratios. Some devices are close to 19.5:9 while others are taller. Launchers may also zoom or shift a wallpaper when you swipe between home-screen pages. This is why important faces, text or details should not sit against the edges.

Keep the clock area readable

Leave a calm area near the upper third of a lock-screen wallpaper. Busy highlights behind the clock can make notifications hard to read. Dark gradients, sky and soft blur usually work well.

How to apply without losing quality

  1. Download the original HD image instead of taking a screenshot.
  2. Open Settings and choose Wallpaper or Wallpaper & style.
  3. Select the downloaded file and preview the crop.
  4. Keep the main subject inside the centre safe area.
  5. Check both the home screen and lock screen before saving.

Final tip

Start with more pixels than your screen needs. Cropping a large image normally stays sharp, but stretching a small image creates blur and visible blocks.
