In addition, the mid parental height (MPH) is used to calculate the expected height potential and interpret the growth curve of a child. [3] The following calculations are used for males and females respectively: Male = (father’s height + mother’s height + 13 cm)/2 Female = (father’s height-13 cm + mother’s height)/2. [3]
