How much can you grow after 16??Watch this thread
How many inches can you grow from 16 - 18....
How tall are your parents?
When I was 14, I just had a growth spurt to 6'0, haven't grown since.
That's just my opinion. It's worthwhile doing the above things, because the benefits are phenomenal regardless of whether Height is affected + you won't get this time back. I heard that generally men take longer to grow and stop growing near 20 or something, whereas women grow faster in a shorter period of time and stop growing near 18 or something.
