Unless you’re Elon Musk rich, it’s pretty much impossible to buy a TV that is too big.
I own a 77” TV and the optimal viewing distance for that is 2.7 meters for a THX recommended viewing angle of 36°. The size goes up quickly the farther you sit from the screen. If your couch is 4 meters from the screen you’re already looking at a 114” screen to get the same 36° angle.
