Ah like the old MKBHD "screen has an aspect ratio of 18:9. Or 2:1 because I know my fractions"

Or just 2. I like my screen aspect ratios in decimal representation. The "wider" the image, the larger the number. Square would be 1.

It makes it easy to compare ratios: for example the aspect ratio of a movie (say 2.39) to my screen (2.33) and see that I can expect a good fit. My screen is a bit "more square", so there will be slivers of black borders on top and bottom.

		To be frank aspect ratios as the main measure are just silly. Instead of 24" screen with a 16:9 ratio they should just be sold as 53 x 30cm. Look at the silliness with folding displays where the difference in diagonal seems marginal until you open up a folding phone and realize that diagonals are just a silly way to measure things.
