Child Height Predictor
Predict adult height based on parents' heights.
How does the child height predictor work?
The child height predictor uses the mid-parental height method, a well-known formula used by pediatricians. For boys: (father's height + mother's height + 13) ÷ 2. For girls: (father's height + mother's height – 13) ÷ 2. The result gives an estimate of the child's adult height, usually within ±5–10 cm of the actual growth.
How to use the Child Height Predictor
Select the child's gender, then enter the father's and mother's heights in centimeters. Click "Calculate" to instantly see the predicted adult height. It's a simple and quick way to estimate how tall your child might grow up to be.
Example calculation
Father is 175 cm, mother is 165 cm. For a boy: (175 + 165 + 13) ÷ 2 = 176.5 cm. For a girl: (175 + 165 – 13) ÷ 2 = 163.5 cm. These values represent the most likely adult height based on parental genetics.
Frequently Asked Questions
How accurate is this prediction?
The mid-parental height formula is a widely accepted estimate, but actual height can vary due to nutrition, health, and other genetic factors. Most children will fall within ±5–10 cm of the predicted height.
Does this work for multiple children in the same family?
Yes, but siblings can still vary in height due to the random combination of genes. The prediction is an average estimate — individual results will naturally differ.
