1584 x 396 pixels
1584 x 396 px is a 4:1 landscape size, the LinkedIn banner size. 1584 divided by 396 is 4, and dividing both by their greatest common divisor, 396, reduces the fraction exactly to 4:1. It is 0.63 megapixels (627,264 pixels) with a diagonal of 1,633 px.

1584x396 vs 396x1584
396x1584 is the same two numbers swapped, and that makes it a different shape: 1:4 portrait instead of 4:1 landscape. Width is always written first, so 1584x396 is 1584 pixels wide and 396 tall, while 396x1584 is 396 wide and 1584 tall. As decimals that is 4 against 0.25. Cropping one to fill the other keeps only 6.3 percent of the picture, so the two are not interchangeable.
No platform size in this dataset is 396x1584: every use listed above is 1584 wide by 396 tall. If an export meant for one of them comes out as 396x1584, the two numbers were entered the wrong way round.
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 1584 by 396 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.
