Monitors come in a handful of standard resolutions. Pick a wallpaper that matches yours (or is larger) and it fills the screen perfectly. Here are the common ones.
| Monitor | Wallpaper size (px) |
|---|---|
| 1080p / Full HD | 1920 × 1080 |
| 1440p / 2K (QHD) | 2560 × 1440 |
| 4K / UHD | 3840 × 2160 |
| 5K (iMac / Studio Display) | 5120 × 2880 |
| 8K | 7680 × 4320 |
Ultrawide and dual monitors
Ultrawide and multi-screen setups are wider than normal, so a standard 16:9 wallpaper leaves gaps. Use these instead:
| Setup | Wallpaper size (px) |
|---|---|
| Ultrawide 21:9 | 3440 × 1440 |
| Super ultrawide 32:9 | 5120 × 1440 |
| Two 1080p monitors | 3840 × 1080 |
| Two 1440p monitors | 5120 × 1440 |
The safe choice: a single 4K (3840 × 2160) image looks great on almost any normal monitor — it scales down cleanly to 1080p and 1440p, and fills a 4K screen exactly.
