Hi!

There is actually none, and because it depends on genetics like who your parents are, how much and when they grew, their environment and so on and so forth.

You can also check the child’s activities such as if he/she is physically active? Is he/she getting enough exercise? Is she eating healthy? and so on.

There is only one thing you can do to increase height. Eat well, exercise, and be patient. The teenager will end up being exactly as tall as he/she is supposed to be. They may be that tall a bit sooner or a bit later, but beyond supplying the building blocks of growth, it is pretty much out of our hands.

Hope this helps!
