What resolution are these wallpapers?

Most wallpapers are available in high resolution, including Full HD and 4K, so they look sharp on all Mac displays.

The library is split roughly evenly between 4K (3840×2160) and Full HD (1920×1080), with a smaller number of files above 4K — around twenty are 5K or wider, tuned for the 27‑inch Studio Display and the Pro Display XDR.

Almost everything is 16:9, which is what Mac displays use. For ultrawide setups there are around fifty 21:9 files and a handful at 32:9 (5120×1440). Vertical 9:16 files exist but only a few, so this is not the place to look for a phone wallpaper collection.

Every wallpaper page lists its exact resolution, aspect ratio, duration and file size, so you can check before downloading rather than after.
