Child Height Calculator

The child height calculator uses a series of formulas and statistical data to predict a child’s adult height based on 6 simple variables (child’s gender, age, height and weight, mother and father’s heights).

A second method that can be used is the gender-specific mid-parental three step method:

■ The first step is to add the parental heights together (whether provided in inches or centimeters).

Mid-parental height = (mother’s height + father’s height) / 2

■ The second step is to add to the value obtained at step 1, either 5 inches (13cm) if the child’s gender is male or subtract 5 inches if the gender of the child is female.

■ The third step is to divide the value obtained at the second step by two, which finds the end results – the child’s future adult predicted height.

Girls Height Formula = (Mid-parental height – 5 inches) / 2

Boys Height Formula = (Mid-parental height + 5 inches) / 2
