I'm measuring out space for a new TV, and I just used the Pythagorean Theorem to figure out what size TV would work best in the spot I have in mind.
THE MOTHERFUCKING PYTHAGOREAN THEOREM. I haven't thought about that shit for like 30 years. It just makes me feel kind of icky. --- "Wall of Text'D!" --- oldskoolplayr76 "POwned again." --- blight family ... Copied to Clipboard!

I dont have any good math puns to share atm, so Im gonna refrain from posting in this topic.

My basic method for deciding a TV is looking at what I have, going "could I use a bigger TV?", then ultimately getting something bigger.
So far I have a 65". Thinking when I need to replace that I will probably go up to a 75" or 80". --- My bookshelf: https://www.goodreads.com/review/list/152760030 Comics: https://leagueofcomicgeeks.com/profile/dikitain ... Copied to Clipboard!

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. Add a couple extra inches for the screen borders, and I had the size I needed.

you could have just googled the chart

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". ConfusedTorchic posted... 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. --- "Wall of Text'D!" --- oldskoolplayr76 "POwned again." --- blight family ... Copied to Clipboard!

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". That's an okay approximation, but it's really only accurate for 4:3 screens, so it's not the most reliable now that widescreen has become so standard. For 16:9 ones, using a 4:3 ratio to calculate will result in underestimating the width by ~25% if you start with a known height, or overestimating the height by ~33% if you start with width. That's offset a little in that the screen border tends to be a bit wider on the bottom to fit the controls in, but 3:4:5 is still going to be a pretty rough estimate. Of course, I'm also the sort of person who routinely uses algebra to help with video games, so perhaps I'm a bit more of a stickler for doing the math than most. --- This is my signature.
