Child Height Predictor

Predict your child's adult height using the mid-parental height method. Uses parent heights and child's current growth percentile.

What is Child Height Predictor?

This child height predictor estimates adult height using the mid-parental height formula (average of adjusted parent heights) and current growth percentile. Provides a range rather than a single number, as genetics account for about 80% of final height.

This calculator uses clinically validated formulas from peer-reviewed nutrition and medical research. The child height predictor computation follows WHO guidelines and established health science methodology. Results are general estimates — individual variations based on genetics, medical conditions, and lifestyle factors may apply.

Frequently Asked Questions

How is adult height predicted from parent heights?

Mid-parental method: Girls = (Father's height − 13 cm + Mother's height) / 2. Boys = (Father's height + Mother's height + 13 cm) / 2. Actual height typically falls within ±8.5 cm of this prediction.

Can nutrition affect a child's predicted height?

Yes. Adequate protein, calcium, Vitamin D, and overall nutrition can help children reach their genetic potential. Malnutrition can reduce final height by 5–10 cm. Growth hormone issues need medical evaluation.
