One more thing about display sizes and aspect ratio:
Since display sizes are usually given by the length of the diagonal, those aspect ratios that are closer to a square (1:1) will have a bigger area for the same diagonal. With the same diagonal length, a 16:10 has a ~5% larger area than a 16:9, and a 4:3 has a ~12% larger area than the 16:9.
This is a nice tool for display size calculations: https://displaywars.com/
