Basement: Screen size

This weekend we'll be doing a test setup of the screen and projector. It's a 100" 16:9 wide screen and the main seats will be about 12' away giving a 33.7 degree viewing angle from the center seat. Yes, that's a one hundred inch screen. Too big? Nah. I tested this setup in a few different stores and I'm happy with the size. Also, when watching 4:3 "TV-sized" content the viewing size will be only about 82". The THX recommended 16:9 screen size for this seating distance is actually 107", so maybe it's even too small (ha ha).
