There is a formula that we use in pediatrics to estimate the size one expects a child to be, based solely on the parents heights. This is called the mid-parental height. It does not give an accurate prediction of a child s ultimate height, but does give a range, based on genetic factors. If either of the parents had health problems as a child, then this estimate may not be accurate.
The way that this formula works is that if the child is a girl, you subtract five inches from the father s height, and then average the result with the mother s height. This average is the mid-parental height, and you would expect the child to be within a few inches of this height (either above or below) as an adult. For a boy, you add five inches to the mother s height and then average it with the dad s.
Based on your parents heights, your mid-parental height is 5' 1-1/2" give or take 3 inches, so we would expect your height to be in a range from about 4' 10" to 5' 4". In other words, you should not expect to be a lot taller than you already are, but you may grow a few more inches.
