How tall will i grow?

It all depends on what you do the next couple of years. Girls stop growing until they are 18. So if you exercise, eat well, stretch, sleep before 10pm, drink milk, there are a lot more stuff that improves your chances on growing taller..but it only adds a couple of inches. It all comes down to your genes. And so far it looks like you'll be around 5'7 or 5'8 your 5'4 now so you only got 3 more years to go.
