What will my final height be?

I'm 15 6'2 and 1/2ft tall and weigh 274 pounds, and wear a size 15 4E shoe, my Dad is 6'4 and my mom is 5'8. Also unlike most tall people my age I am not thin and lanky, I have very wide shoulder and am pretty solid, I think I'm done growing, but males arnt so posed to stop growing untill until 21. What do you think, I'm hoping I will reach 6'5 at least.
