It's kind of shitty and deceptive to measure screen size by the diagonal. You could have literally a single row of pixels 15 inches wide; does that mean you have a 15 inch display?
How would you recommend we measure screen size? Length x Width I assume is the obvious one, but that’s harder to compare. I suppose you could argue comparing diagonals isn’t a good benchmark either, but it works well enough when screens tend to have similar aspect ratios, as they mostly do.
HxW would be easier to compare if anything. Today you have to look at the aspect ratio to even figure out what the diagonal really means (and the difference between, say, 2:3 and 16:9 is huge).
