Ideal distance from TV to sitting/viewin position

For TV, probably 3:1 screen widths (not diagonal measurement). So for a 65inch 65/1.15*3/12= 14 feet. You might be able to push that up to 4:1 for regular TV. For home theater, collapse that to 1.5-2.0 screen widths. 65/1.15*1.5/12= 7 feet. To sit farther away will pretty much require front projection. There are a lot of good digital projectors from $800-2000, check the AVS forums.

Well 12ft for a 92 diag. is just right for me. In about 1hr I'm thinking "I can see a little light between---can't we go bigger?" Some movies give me a headache----just never the screen size.

The distance that you sit from your TV depends more on the signal source rather than screen size. While viewing a regular TV signal, you should sit about ten feet in front of a 50 inch screen. However, with a high definition image, you could move up to a viewing distance of six feet or closer without ill effects. The picture is so detailed that it will seem like you are looking through a window instead of at a TV screen.
