To grow taller, you need at least eight hours sleep per day because you grow at night when your body is at rest. This is what my brother-in-law told me and he is a doctor. Usually, males grow until they are about twenty years old. Females stop growing when they are around fifteen years old, they could go a little longer. Your being short could also be genetic. If your parents are short, then expect to be short also. This is all I can tell you.

Short of investing in a medieval rack,not much.Excercise is important.But keep it sensible & get plenty of sleep too.

My father used to say that standing in cow pats made you grow but I think he was kidding.(It didn't work for me!).LOL

Don't stress and don't go to summer school.  Summer is the time for you to grow. 

Stand  in a pail of horse dung ,with a gas mask on,for 3hours a day,with your trouser legs rolled up,
