I am 6 feet 2 and i will be 19 in 3 months. i wear shoe size 14 and i have a wingspan of 7 feet. i have a little bit of facial hair but not much. can i still grow taller or i am completely done?

Maybe/not. People can grow taller until the growth plates in their bones close. An x-ray of your wrist/hand can be assessed for the status of the growth plates. If open, more growth is likely, if closed, you are done. Most males stop growing taller at 16-18. If you grew more than 2.5 inches in the past year you may grow more, if less than an inch you are less likely to grow much.
