I don't remember the exact context, but I ended up doing that in reverse once to figure out how wide a TV was that I didn't have definite dimensions for: Take the known diagonal measurement, substitute 9L/16 for the height, expand everything out and solve the equation.

That's sort of what I was doing. I calculated based on the max height I had available and then figured out what the other two dimensions (width and diagonal/screen size) would wind up being, then I calculated what I'd get from a specific max width, and sort of played around with stuff a bit. So I could come up with an optimal size for the space.

It's generally easy to work with the three dimensions if you remember 3/4/5 for the sides of a triangle (which TVs generally conform to), and only resort to the full a + b = c if you really need to. So I was able to, say, calculate out pretty easily with 44" wide I'd get 33" high and a diagonal/screen size of around 55".

you could have just googled the chart

I actually did later (that exact page, in fact), but not because of the TV size, as much because I wanted to see the "how far away are you supposed to be sitting away from the screen" info.

I didn't go looking for it for the measurements because I didn't really need to at the time. I actually just found it easier to pick up a calculator and do the math than it was to go look up charts or anything pre-established.

Though the sad part is afterwards I mostly just shrugged and decided I'm probably going to keep my two 32" screens I have (side-by-side for multitasking and for two-screen co-op gaming) rather than upgrade to something bigger anyway. Though I might still change my mind.
