I get different awnsers on if you grow at 17 like a couple inches I know it's different for everyone but how likely is it for a 17 year old + to grow 2-3 inch for an amarican white guy?

Dude. Seriously. Stop asking this question. Your height is based on GENETICS. Impossible to predict - your doctor can give a best guess based on mom and dad, however, it's a guess. Our doctor predicted my son, based on my height and dad's guessed he would be at least 6 foot. He topped out at 5'9. My son was bummed but got over it. Please stop asking this question. Thank you.
