I have a 60" and recently moved to a place with a smaller room. I am about ten feet away and its to close. I dont like to have to turn my head to see the whole screen. I would measure how far your seat is fron the tv and then stand that far away from the tv's you are looking at.
How big is too big?
There has to be some sort of ratio of room size to screen size. I was thinking about getting an 84" screen but realized that it would be WAY TO BIG for the room after drawing it on the wall with chalk. Have any of you put too large of a TV in a too small room, or the other way around?
