How to Use This Calculator

1. Enter the height of the father in centimeters (cm).
2. Enter the height of the mother in centimeters (cm).
3. Select the gender of the child (male or female).
4. Click the "Calculate" button to see the estimated height.

How It Works

The midparental height is a method used to predict a child's adult height based on the heights of the parents. This method assumes an average genetic potential for height and considers that children typically reach about 85% of the combined height of their parents.

For male children, an additional 13 cm is added to account for the typical greater height potential in males. For female children, 13 cm is subtracted to account for the typical smaller height potential in females.

Important Notes

• This calculator provides an estimate only and should not be used as a definitive prediction of a child's height.
• Actual height can be influenced by many factors including genetics, nutrition, health, and environmental conditions.
• This calculator assumes both parents are of adult height. If parents are still growing, their heights should be adjusted accordingly.
• For the most accurate height predictions, consult with a pediatrician or healthcare professional.
