Android size method
Phone Wallpaper Size Android
Android has no single wallpaper size. Display resolutions, aspect ratios, launcher behavior, scrolling, and manufacturer UI all vary. A screenshot from your phone gives the most reliable starting pixels.
The reliable answer: match a screenshot
- Take a normal portrait screenshot on the target Android phone.
- Open the screenshot in Google Photos or the gallery and view Details or Info.
- Copy the pixel width and height into Custom pixel size.
- Use Fill for edge-to-edge photography, or Fit/Blur fill when the whole source must remain visible.
This method measures the phone’s current screenshot canvas. It avoids guessing from the diagonal screen size, which is measured in inches and does not reveal pixel dimensions.
Android reference sizes
| Device or ratio | Portrait pixels | Source |
|---|---|---|
| Google Pixel 9 | 1080 × 2424 | Google hardware specifications |
| Google Pixel 9 Pro | 1280 × 2856 | Google hardware specifications |
| Google Pixel 9 Pro XL | 1344 × 2992 | Google hardware specifications |
| Common 20:9 working size | 1080 × 2400 | Ratio-based fallback |
| Classic 9:16 working size | 1080 × 1920 | Older/full-HD content fallback |
Google lists the Pixel 9 at 1080 × 2424 with a 20:9 display description, and lists separate higher resolutions for the Pro models. Use the exact phone when available; use a generic ratio only when the model is unknown.
Why an Android launcher may still crop
Some launchers pan a wallpaper across multiple home-screen pages. Others zoom the image to support transitions or motion. A bitmap that exactly matches the display can therefore lose edge content.
- Keep faces, logos, and text inside the central 80% of the frame.
- Preview Home screen to reserve space for icons, widgets, and the dock.
- Use Blur fill when a wide source should remain complete on a tall screen.
- If the system picker zooms, look for scrolling, motion, or perspective controls before re-editing.
Calculate a proportional fallback
If you know the target aspect ratio but not the full resolution, select a useful width and calculate height:
Formula: height = width × ratio height ÷ ratio width. For a 20:9 screen at 1080 pixels wide: 1080 × 20 ÷ 9 = 2400.
A higher pixel count does not repair a low-resolution source. It only creates more output pixels. Start with the best original photo you have.
Android format choice
JPEG is the safest compact choice for photographs. PNG works well for illustrations and typography. WebP is efficient, but use JPEG or PNG if the wallpaper picker, sharing app, or older device rejects the file.
