I'm a 15 year old boy, 156 pounds and 5'2.my mom is 5'2 and my dad is 5'7.what is my predicted height ?

Closer to your Dad: How about your grandparents--and do you have older siblings? There's this thing called "regressing to the mean" that says you'll be closer to average than your folks. If you need to know an x-ray of your wrist will give you a "bone age" and let you know what to expect.

Depends: Expected height from parent stature is equal to the average parent height (m+d/2) + 2.5 inches for males. This calculates to 67" for based on genes. This is only a basic predicted height. Some very tall or very short people come from normal sized parents, & a life's medical issues can slow the growth of anyone.
