How It Works

How It Works

This calculator estimates a child’s expected adult height using the Mid-Parental Height method. It takes the average of the father's and mother's heights to give a simple prediction.

The formula adds both parents’ heights together and then divides the total by two. The result is rounded to one decimal place to keep the number clear and easy to read.

  • Adds the father's height and mother's height
  • Divides the total by 2 to find the average
  • Rounds the result to 1 decimal place
  • Returns the estimated adult height in centimeters (cm)

Understanding the Results

The result shows an estimated adult height based only on parental height. It gives a general idea, not an exact prediction.

Many other factors like nutrition, health, and genetics can influence final adult height. Use this estimate as a helpful guideline rather than a guarantee.

  • The value is an estimate, not a fixed outcome
  • Based solely on parents’ heights
  • Does not account for lifestyle or health factors
  • Best used as a general growth reference
