>>11542922It depends on the person I definitely stopped growing at around 17 if not 16.
Some people keep growing until 20 but I think it's rare. Growth spurts are quite a well known science now and especially at around 14 it's quite easy to maximise a childs height with diet and weightlifting. That's the major growth spurt.
I was playing vidya and eating a mini fillet burger a day at that age sadly.
