Growth, development, and perportions.

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.
