Height Prediction Formula:
From: | To: |
The height prediction formula estimates a child's adult height based on the parents' heights. It provides a rough approximation of genetic height potential, though environmental factors also play a role.
The calculator uses the height prediction formula:
Where:
Explanation: The formula averages the parents' heights with an adjustment factor that accounts for typical sex differences in height.
Details: While not definitive, height prediction can help parents and pediatricians monitor growth patterns and identify potential growth disorders early.
Tips: Enter both parents' heights in centimeters. The calculator provides an estimate for male children. For female children, subtract about 13 cm from the result.
Q1: How accurate is this prediction?
A: The formula predicts within ±5 cm for about 70% of children, but nutrition, health, and other factors affect final height.
Q2: Can this predict height for girls?
A: Yes, but subtract 13 cm from the result or use (mother's height + father's height - 13)/2.
Q3: At what age is prediction most accurate?
A: Predictions become more reliable after age 2, when genetic factors begin to dominate over birth factors.
Q4: What if parents are very tall or short?
A: The formula works best for average heights. Extremes may be less accurate due to regression toward the mean.
Q5: Can environmental factors affect the result?
A: Yes, nutrition, chronic illness, and hormonal factors can all influence final height beyond genetic potential.
