Eli5 – aspect ratios

307 views

Ok, i sort of get it but i don’t. 1:1 is square 16:9 means it’s 1.77 x’s wider than it is tall. But what the hell does 9 actually represent considering it comes in many sizes from small to large yet same ratio, so what makes one side 9 or what ever? For instance why not just say 1.77:1?

It’s just a matter of cleanliness. “16:9” is simpler than “1.777777778:1”. “4:3” is simpler than “1.333333333:1”
