I'm actually a swimmer, so my height can really help me improve my times.
Thanks
Answer:
It can really differ.
I stopped growing when I was about 14. All what has happened since is that I've filled in (a little bit). I am now 19 and still the same.
And by the same token you could have stopped because you already passed your mom 4'' ago.
But it looks to me like you growing in spurts. Alot here, and then nothing. If that has happened before, you may get at least one if not more chances to spring up like that again.
But check this out, my uncle is 7'' taller than his dad and much more than his mom.
So flip the coin and see the result.
You're only 15, so you're probably still growing.
Unless for some odd reason your epiphyseal plates have closed.
well, i really don't know the answer
but from 17years old - 19years old i grew 6 inches
(i'm currently 19)
Well, I'm no doctor, but is is quite possible that you have stopped growing. I'm fourteen, but I have a friend who is fifteen who is about 5'2". She has completely stopped growing, so it may also be possible that you have as well.
By the way, best of luck with you and your swimming!
