What height should you be if your 12 years old?

In my opinion, there is no exact age height you should be when you are twelve. Our heights can depend on many things like: Genes or family DNA Puberty-Growth spurts Whether you are a girl or a boy Or if you have a disease that affects your growth. If your friends are taller that you, it is probably because they play a particular sport or are having a growths spurt. Do not worry if you are the shortest in class, this could also mean that you have not had your growth spurt yet.
