I know this has been discussed here a million times before, with varying answers, but here goes again anyway. I am currently looking a a new home design that has a separate room over the garage (yeah, no waking up the family), which I intend to make a dedicated HT room. I am shooting for a front projection system (eyeing the Sharp XV-Z9000). The room dimensions (as they stand via the builder) are 10'4" wide by 20' long. I was looking at seeing if they could expand the width by a couple feet. What do you guys (and gals) think the appropriate width should be (i.e. what is reasonable to fit say a 90-100" screen). Also, should I attempt to stretch out the length a little too? I was thinking like 12-14' wide and 22' long. HELP?
