I'm an 18 year old guy.
Im 5'9.
Mom is 5'6 or 5'7.
17 year old sister is 5'7
My father is 6'2.
6,2 uncle(mom's side)
I'm more concerned with my perportions. I have a bigger head and my wingspan(distance from fingertip to fingertip with stretch out arms)
is 6'3 ( wingspan grew from 6' to 6'3, almost a year ago now)
My torso is really short compared to my legs. Am I likely to grow to be more perportional? I feel and look awkward.
Trying to find answers elsewhere and found resources I've read online claims for the majority of the adults height and wingspan is a 1:1 ratio. Or roughly the same.
