Tall-wise I finished growing at 18. I was always late behind everyone else in growth, so much so no one would have thought it odd for my final height to be 5'2" or something. But I eventually grew to 5'6".
I had an head shorter (9+ inches) shorter than all boys in any of my classes throughout all school years. I think I've been taller than a handful of girls in early elementary and maybe late 10th grade. By 11th grade I was a bit above 5 feet. Here the school system has only 11 grades, so I graduated then, and couldn't compare afterwards really.
I feel short, or tall at times (relative to people I'm with), but generally I don't really care.
