At 6'3" and 220 lb. I overfill a coach seat (when I can't get an upgrade). However, I seldom have a problem with recliners. Seems that when I am seated in some of those short pitch coach seats, the distance between my back and my knees is such that the person trying to recline finds that their seat doesn't go back. After trying for a few times, they generally give up and I can relax my legs under the seat without having a seat back in my face.
