Predict your child's adult height using scientific methods
Height prediction combines genetics, current growth patterns, and statistical models to estimate a child's adult height. While no method is 100% accurate, these calculations provide a reasonable range based on scientific research.
(Father's height + Mother's height ± 13 cm) ÷ 2
Simple genetic calculation based on parental heights. Boys add 13 cm, girls subtract 13 cm.
Accuracy: ±8.5 cm
Complex formula using age, height, weight, and parental heights
More accurate for children ages 4-17. Accounts for current growth patterns.
Accuracy: ±7 cm
Combines current height percentile with genetic potential
Statistical model using current height to adjust genetic prediction.
Accuracy: ±6 cm
Percentile tracking from birth to adulthood
Based on global population data. Tracks consistent growth patterns.
Accuracy: ±5 cm
