Frequently Asked Questions
How accurate is the mid-parental height method?
The mid-parental height method is accurate within about 2 inches for most children. However, nutrition, health conditions, and other genetic factors can cause actual height to differ from the prediction.
Do boys and girls use different formulas?
Yes. For boys, 5 inches are added to the average of the parental heights. For girls, 5 inches are subtracted. This accounts for the average height difference between males and females.
