Predict my adult hight plzz.... i am 13 and 20 days old my hight is 5"0?

Yes of course. Guys don't stop growing till their 20's. So you have a long way to go. (i'm assuming you're a guy) And for girls, i believe they stop growing at 16 or 18. So either way. It's not all genetics and there no way to predict your actual height. But i'm more than sure that you'll reach 5"7
