Tragedy At It's Best.
I bought a DLP Projector and want to set up a Home theater. My room size is 13 * 12 feet

Jerry,
The spread sheet was very informative, which the member has given to you.
I think whatever the size of your screen, the easiest way out for you to salvage the situation is now, to reduce the picture size to around 35/40 inches, this way you will loose the charm of a much bigger picture size of say 80 - 100 inches, so the whole charm of having a projector has been defeated.
I think that you have still not bought the screen, if this is so, than maybe i can suggest you some other way out, which may give you some relief rally. The idle way would be if you can return the projector to the dealer, but he will not take it, till you use a gun at his fore head.
When my mini theatre was in the making i also had realized that my room length is small, so i had to remove my bathroom, to make the room longer, so now my theatre room length is 23 feet, while it was earlir at 17 feet.
When my mini theatre was in the making, I had got my wall white painted to a screen size 90 inches breadth with a height of 7 feet, than for several days I saw full movies, with different sizes on the white wall, I used markers and measurement tapes to set different sizes, finally I choose two sizes, 72" x 3.5 feet (16 x 9 - Dnp brand), and 82" x 5 feet (4 x 3 Dalite brand).
To conclude i also have gone through a lot of tragedy during the making of my theatre.
Vinay.
