I am making a new room for home theatre, it will mainly be used for this, but also partially as a scond living room. The room is 16 feet 3 inches by 12 feet 4 inches. I plan a 11.2 setup with a projector. Should i have the screen on the longest or the shortest wall? What are the drawbacks and upsides of the different setups?

I am planning 1 row and some chairs, I would like to have 4 chairs in the row though.
I have attached a crude sketch wich indicates the room, and on which walls windows there are windows and doors. Exact placement on the the wall is not given yet. (the sketch presumes screen on narrow side)
11.2 will be standard 7-channel setup, and 4 added DSX-channels. Acoustic treatment will mainly be low freq absorbtion (membrane in corners i guess). Speakers will be behind screen (not decided if they will be in-wall yet though). Projector is not yet bought. I will setup windows so they can be blacked out
I hope this info can be of help, as you see, its all very early in the planning fase, and very little is final.

In a room 12' 4" wide, with the projector/screen on the 12' 4" wall, forget "Wide" speakers. "Heights" might be doable, depending on ceiling height, but the room simply isn't wide enough for "wide" speakers. You need 60 degrees of separation for each wide speaker:
Transferring the placements in the Audyssey drawing to your diagram, you would need to place the "wides" on the side walls just about where the side chairs are to get 60 degrees from the primary listening position.
If you turned the system so the screen is on the 16' 3" wall, you might be able to use "wides", but then you are sitting closer to the back wall and closer to the display, (probably too close if you're using an AT screen with speakers behind it.) I would not suggest that arrangement unless the wide channels are really important to you.
Also, realize that the *only* seats that will be advantageous for the wide speakers are the middle seats on the couch, (this will be true, no matter the configuration of the room.) The end seats on the couch and the side chairs will suffer from the "image" collapsing to the closest speakers. For example, the left-most seat on the couch and the left side chair will get most of their sound levels from the L main, the left wide and the left surround speakers. Any dialogue that is supposed to be centered on the display will probably be OK, but very little will "image" from the right side of the screen.
Frankly, I suggest you start out with a standard 7.1 system. (Wire the room for 11 if you like, but I wouldn't make a commitment to buying all the speakers until you see if 7.1 is enough in your room. (I suspect it will be.)
