            Disclaimer: This predictor uses the Khamis-Roche formula. The coefficients used in this demonstration are illustrative (approximated for a child around 5 years old) and are not dynamically adjusted for the child's specific age entered. For accurate predictions, a comprehensive set of age-specific and sex-specific coefficients is required, as per the original Khamis-Roche studies. This tool is for informational and demonstrative purposes only and should not replace professional medical advice. Consult a healthcare professional for accurate growth assessments.

Predicting your child’s adult height can be both a fun and insightful process, offering parents and caregivers a glimpse into their child’s potential growth trajectory. Our Child Height Predictor is designed to provide a reliable estimate using the Khamis-Roche Method, a scientifically validated approach that calculates adult height based on current height, weight, and parental heights.

What is the Khamis-Roche Method?

The Khamis-Roche Method is a proven, non-invasive formula used to predict a child’s adult height with reasonable accuracy. Unlike traditional methods that require X-rays or bone age assessments, this method leverages simple measurements: the child’s height, weight, age, and the height of both biological parents. Developed in 1994 by Dr. Harry Khamis and Dr. Alex Roche, this method remains one of the most reliable tools for estimating adult stature for children aged 4 years and older.

Key Facts:

For boys, the margin of error is about 2.1 inches (5.3 cm).
For girls, the margin of error is approximately 1.7 inches (4.3 cm).
Ethnic background may influence prediction accuracy, as the original research focused on Caucasian children.

Limitations

The method is most accurate for children aged 4 to 17 years.
It was primarily studied in Caucasian children, so ethnic factors might influence the prediction.
Environmental factors such as diet and overall health can affect actual growth.
This tool provides estimates, not guarantees.

How to Use This Tool

Step 1: Enter your child’s age (must be 4 years or older).

Step 2: Input the child’s current height and weight.

Step 3: Enter the heights of both parents.

Step 4: Click “Calculate” to get the predicted adult height.

Additional Methods

For younger children or infants, the Mid-Parental Height Method is also available. This method estimates adult height by calculating the average of the parents’ heights, adjusted for gender. However, the Khamis-Roche Method is more accurate for children aged 4 and older.

Summary

Our Child Height Predictor tool, powered by the Khamis-Roche Method, offers an easy-to-use and scientifically backed way to estimate your child’s adult height. By factoring in genetics and current growth data, this tool provides a personalized estimate that helps parents and caregivers better understand and track their child’s growth potential.
