Screen wallpaper calculator
Wallpaper needs depend on the screen shape. Use this helper to compare desktop, phone, tablet, and ultrawide ratios before exporting.
Live preview follows the selected ratio.
Calculator
Choose a ratio, enter width or height, and the calculator fills the matching dimension while keeping the image or video proportional.
Use these sizes as starting points. Exact platform requirements can change, so treat the calculator as the proportional reference and check the final upload screen before publishing.
| Use case | Pixel size | Ratio |
|---|---|---|
| Full HD desktop | 1920 x 1080 | 16:9 |
| 4K desktop | 3840 x 2160 | 16:9 |
| Phone wallpaper | 1170 x 2532 | 195:422 |
| Ultrawide | 3440 x 1440 | 43:18 |

Design larger than the target when possible.
Keep the subject centered for devices that crop slightly.
Use separate exports for desktop and phone.
This reference chart shows how common frames compare. Use it when deciding whether a creative should be wide, square, portrait, or ultrawide.
