An 8' wide 16:9 screen (110" diagonal) is a nice comrpomise for a 12' viewing distance. Scope movies are a little small, sub-par transfers of lower aspect ratios are a little big. A 113" x 48" scope screen would work better if you can accomdate the width.
At 8', I'd want to run something on the order of 75" x 32" but would settle for a 64" wide 16:9 screen (73" diagonal).
The 16:9 screen dimensions give you the same subtended field of vision you get sitting in the farthest seat from the screen in a theater meeting the THX recomendations. Most of us like to sit a bit closer to the screen.
You need to think in terms of small movie screens not large TVs. In doing so, you'll find that two-piece projection setups are required for all but the smallest living rooms.
