This is mostly useless, except to justify buying a bigger TV. However, I did learn:
- For most popular high end models, the 65 inch models are cheapest / sq inch (e.g Sony A95L, Samsung S90D, LG G4). For most others, it's the 75 inch models.
- TCL S551F 55" scores the lowest ($0.17/sq inch)
- The lowest scoring OLED is the Samsung S85D ($0.55/sq inch)
- For 100 inches, Hisense QD7 is the cheapest ($0.37/sq inch). For 85 inches, it's the TCL S551F ($0.22/sq inch)

There's not much point in optimizing completely for price per inch, but when I bought my TV in 2013 I plotted this, and discovered a pretty sharp hockey stick in the graph at 70" and above. So I got a 65" TV. If my graph had looked pretty straight like yours I'd probably just get the biggest that is practical for the space.
My SO wants a bigger screen, and I was thinking of a 65", but maybe I'll consider a 75" instead since it seems like a sweet spot for value.
I've also debated getting a projector. It's in a basement, so I can get a blackout curtain for daytime use.
Same thing for 100 inch models now. Maybe it'll flatten out in a few years.
yeah you'd have to get a rear projection DLP to get a bargain at that screen size back then. around 2010 i picked up a 73" DLP for less than a grand at costco, but i used some lucky discounts, or it would've been 1100 or so on sale.
most people don’t like those bulky TVs though, even back then. or even have room for them.
I followed a roughly similar process but the flow was more like, "Here's a 65-inch TV on sale, let's bump up our 48."
