What is the Galaxy S23 Ultra wallpaper size?

1440 x 3088 pixels, the native resolution of the 6.8-inch QHD+ Dynamic AMOLED 2X display. Upload at this exact size for a pixel-perfect fit. The phone runs at FHD+ (1080 x 2316) by default to save battery, but its true panel resolution is 1440 x 3088.

Is the S23 Ultra wallpaper the same size as the S24 Ultra?

Almost, but not exactly. The S23 Ultra is 1440 x 3088, while the S24 Ultra and S25 Ultra are 1440 x 3120, very slightly taller. A wallpaper made at 1440 x 3120 works on the S23 Ultra (it downscales a touch), but for an exact fit use 1440 x 3088.

Should I design at FHD+ or QHD+?

Design at the full QHD+ 1440 x 3088. Even though the phone defaults to FHD+ to save battery, sourcing your wallpaper at the native panel resolution keeps it sharp if you switch the display to its full resolution, and gives the cleanest downscale at FHD+.

Where does the S23 Ultra clock and widgets sit?

The lock-screen clock sits in the upper third, and any widgets sit below it. Keep faces or focal points of a photo wallpaper in the lower-middle so the clock does not cover them. The top status bar occupies roughly the first 90 pixels.

Galaxy S23 Ultra: native QHD+ at 1440 x 3088

The Galaxy S23 Ultra has a 6.8-inch Dynamic AMOLED 2X panel with a native resolution of 1440 x 3088 pixels (about 500 ppi), in a roughly 19.3:9 aspect ratio.

Two things are worth knowing for wallpapers. First, Samsung ships the phone at FHD+ (1080 x 2316) by default to extend battery life, so many people never run it at full resolution. Sourcing your wallpaper at the full 1440 x 3088 means it looks right whether or not you switch to QHD+. Second, the S23 Ultra is 3088 tall, while the newer S24 and S25 Ultra are 3120, so a wallpaper cut exactly for one is slightly off on the other. For a pixel-perfect S23 Ultra fit, use 1440 x 3088.
