How This Calculator Works

This calculator uses two common scientific methods to predict a child's future adult height based on current age, height, and parents' heights.

Mid-Parental Height Method

For boys: (Father's height + Mother's height + 5 inches) / 2
For girls: (Father's height + Mother's height - 5 inches) / 2

Khamis-Roche Method

This more accurate method considers the child's current height, age, weight, and parents' heights. It is one of the most reliable methods for predicting height in children aged 4-17.

Important Notes

  • These are statistical predictions — actual adult height can vary due to nutrition, health, and genetics.
  • Results are most accurate for children between 4 and 17 years old.
  • Genetics is the strongest factor, but environment also plays a significant role.
