What size screen for front projector?


I have no experience with front projectors but am trying to help out a neighbor. His seating area is pretty well fixed at 14-16' from where the screen will be. He's strongly considering the new Sony 1080P unit. What size screen would be optimum for this viewing distance? Any suggestions on which brand/model screen - he's looking for a fixed mount screen.

www.projectorcentral.com has a calculator for that projecto to show how big of a screen you can use from where the pj is mounted.

The Cardas are a nice pricepoint but if you are spending the coin on 1080p don't shortchange yourself on the screen.... look at the Vultec Silverstar or Stewart Firehawk both are considerably more money but you will be changing pj more often than screens... my Vultec Silverstar was the best investment I could have made (looks likes a plasma in dynamics and perfect off angle viewing with no hotspots..) The Vultec is not the screen to get if you have ambient light because of the silver screen.

www.avsforum.com has tons of threads on comparisons of screens and how they work with each pj... also go with the larger 3" black border so you can shoot over and not have to zoom in and out all the time depending on sources..

Nice PJ your friend is buying!
My seating is about 14' from the screen and I have
a 103" diagonal Stewart Firehawk. I'm using an
InFocus 7205 projector and the combination is stunning.
When watching sports on HDTV it's like looking through
a plate glass window at the ball park.
Thanks for the suggestions. Stewart is the brand that he was thinking about. He won't be able to demo as we live 250+ miles from anything you'd consider to be a good a/v or HT shop. In fact he's buying the Sony sight unseen based on all the extremely positive reviews. He has $10k budgeted and the PJ is about $8k with tax, so he has up to $2K for a screen. Is there a visible difference between models? Is the Studiotek 130 noticeably better that one of their other models? I'll also have him check out avs.forumcom. Guess we know where the neighborhood Superbowl party will be this year!
Guess I'm lucky this year...gearing up for the Red wing and Piston CHAMPIONSHIPS to come...hope it's in hi-def!
