A persons height, when they reach adulthood, has several determining factors. Genetics, diet, lifestyle etc.
It cannot be said, with any precision, what their final height may be.
Growth slows down, or stops, in the late teens usually, however some people can experience 'growth spurts' even so.
Generally if you are taller than average as a child you will be taller than average as an adult but growth can also be arrested, or may slow, in childhood too.Bob Odenkirk is 48 years old (birthdate: October 22, 1962).
