As others have said, you should have plenty of room for a pj setup. Our viewing area is not that different from yours -- 19'2" x 12'5, with a low (7'6") ceiling. From a viewing distance of 13', for 16:9 we set the image at 88" wide. For 2:35 films we use the pj's zoom to set the image at 104" wide. That's what we find comfortable: in theaters, we like to sit about 3/4 back. Sorry, make that, when we used to go theaters.....
I agree strongly with Barth2K that you should project on a wall for a while before you make your screen size decision. See what's comfortable for you with 16:9 and 2:35 content.
Also agree with those who suggest that you offset the projector placement in order to center the image within your 11 foot wide sweet spot.
As for the image size "shrinking" over time due to habituation (and therefore, going with a larger screen now than you've currently chosen), I'll say two things. First, when I began floating the idea of a home theater room/pj to my wife, I took my her to an upper end A/V store. In their smallest showroom they were projecting an "upscaled" standard dvd on a mere 72" wide screen. I had her look at it from roughly 13' and she said "No way," the image was too big and scenes with motion made her dizzy. Now she's watching standard ("upconverted") dvd content at 102" wide and sometimes sits on the floor in front of the couch, so from a distance of about 11'. And whenever I ask her if the picture is too big, she says "No."
Second, your mileage may vary. For 16 x 9 HDTV with a 720p projector neither of us would want a bigger image than 88" to say 90" wide. It's the image height that seems to make us feel this is the limit (and our low ceiling height). But there are plenty of pj owners who would say our image is too small for them. So try it out for a while on your walls and see what works best for you.
