What size screen for front projector?

Guess I'm lucky this year...gearing up for the Red wing and Piston CHAMPIONSHIPS to come...hope it's in hi-def!

My viewing distance is about the same, and I also have a Sony 1080p projector and have a 100" 4:3 Vutec, so my 16:9 is roughly 87". I could, perhaps, go a bit larger but I don't think the projector is bright enough for much more then 100" with that distance. I am assuming you have the VPL-VW100, and it has even lower lumens output then my VPL-HS51a, though both have the auto-iris so if he has a dark room it should do blacks very well even if he goes large.

Tireguy - thanks for the input. Yes, it's the VPL (Ruby) that my neighbor is buying. Now that you mention the fact that the PJ is not bright enough to do more than 100" at that distance, I think I remember reading a review that basically said that same thing. I'll have to look it up and give to my neighbor. I think I also read that replacement bulbs are $1,000!!!

I noticed that the new projector from sony used a xenon bulb, while I am by no means a Hometheater guru, that was a new one on me. It also listed no life expectancy of the bulb, which is probably a good thing. If it lasts twice as long as a conventional bulb then it really isn't out of line price wise.

The right answer is what works for HIM with HIS projector. He needs to buy it, set it up on a white wall/sheet/cheap screen, and see what subtended field of vision works for him. Preferences vary and will change when he gets used to thinking of his setup as a small movie screen instead of a large TV.

At 16:9, most home theater people would suggest sitting at 1.5 screen widths which translates into screens

112" wide at 14 feet to 128" wide at 16 feet
128 and 146" diagonal respectively.

3 heights seems a better number With a 2.35:1 constant height setup using an anamorphic lens
131" x 56" at 14 feet to 150 x 64" at 16 feet

Since this is too big for the Sony's light output, he'd do better sitting closer to a smaller screen.

We often sit 11' from a 87x49" (100" diagonal screen. While about right for most DVDs at <= 1.85:1, good scope transfers are too small. This matches the subtended field of view you get in the last row of a commercial theater meeting the THX recomendations.
