glhcarl's answer seems a sensible one.
dogcharlietree,
One could add that at 6'2" you're over the average.... average height of Europeans and North Americans is more like 5'9" (article on "Human Height" in Wikipedia) so that's 5" right there....
Also, how old is the 737 design? People's average height has probably increased by an inch or two since its first flight
