How do you stop growing taller?

the best advice i could possibly give you is that you see your doctor about it and they may be able to give you some tablet's. I'm tall myself but face it it's better than being a midget plus tall people tend to be more slim and trimmed, although I'd like to be an average size than my current size now- 5.2 I'd rather be this size than being small and midget-like besides you should stop growing at some stage and then other people would catch up with you! :D
