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.
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.”
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.
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.
