1080x1920 vs 1920x1080

1920x1080 is the same two numbers swapped, and that makes it a different shape: 16:9 landscape instead of 9:16 portrait. Width is always written first, so 1080x1920 is 1080 pixels wide and 1920 tall, while 1920x1080 is 1920 wide and 1080 tall. As decimals that is 0.5625 against 1.7778. Cropping one to fill the other keeps only 31.6 percent of the picture, so the two are not interchangeable.

In this dataset 1920x1080 is used by Twitch offline banner (video player).

What the numbers mean

The pixel count is what the file stores. It is not the size the image appears at on a screen, and the two get confused constantly. A display measures its layout in CSS pixels, and most phones draw two or three physical pixels for every CSS pixel. That device pixel ratio is why an avatar that occupies 110 CSS pixels wants a file several times wider: on a 2x screen those 110 CSS pixels are 220 physical ones, and a 110 px file gets upscaled to fill them.

So 1080 by 1920 is a statement about the file, not about how large it looks. Whether it is enough depends on the largest surface it has to fill and on the pixel ratio of the screen filling it, which is why the platform pages above carry a minimum width as well as a recommended size.

9:16 is a shape rather than a size. See every size that uses the 9:16 aspect ratio.
