Frequently Asked Questions
How accurate is the child height predictor?
The Mid-Parental Height formula predicts within about ±8.5 cm. Genetics explain 60–80% of height; nutrition, sleep and health also matter. Use results as estimates, not guarantees.
At what age do children stop growing?
Most girls stop around 14–16, boys around 17–19. Some keep growing slightly into their early 20s. Regular pediatric check-ups are recommended.
What BMI is healthy for a child?
Children's BMI uses age/gender percentile charts. The 5th–85th percentile is healthy weight, below 5th is underweight, 85th–95th overweight, 95th and above is obesity.
Can nutrition affect my child's height?
Yes. Adequate protein, calcium, vitamin D and zinc help reach genetic potential. Malnutrition can stunt growth, but overeating won't exceed genetic limits.
