I won't spend such amount of money in dumb surgeries just to be taller, I actually think height is a dumb thing to worry about but everyone on earth cares about it for some fking reasn, especially women. Anyway, my sitting height is 79 cm while the rest of my height is 76 cm. My head circumference is around 22 inches I am guessing. Swingspan is around 5'2"-5'4". Shoe size 6 1/2, hand length 6.7. My lower body is pretty unproportionate. Btw weight has nothing to do with it, I could get taller and gain weight afterwards, anyhow there is nothing wrong with 102 lbs. I know someone who is 5'11" and weights 105 lbs. I also have a friend whose sitting height is like 82 and he is like 182 cm tall; he doesn't seem unproportionate actually lol but he is actually pretty sturdy perhaps thats why.
