I might be around 12ft or so. I'd have to measure to be sure.
I have a unique room where there is a gap in a corner and it goes deep. It allows me to have the tv stand, tv and my towers and room behind for my sub and AMPs but not as much width as I'd like. So I can't go as big on TV as Id like to. I can go up to 70 which is what I had before I got the 65 OLED. If I had more space I'd have bought 75 and would have bigger towers right now most likely. The infinity R263's work well in that space as they are fairly narrow and perform relatively well.
Anyways, the prices keep going down so the 85+ might be in your reach soon
Just a matter of how much quality you want to invest in vs. maybe pick up a cheaper one on sale just for fun
