1. What is the Height Prediction Formula?

The height prediction formula estimates a boy's adult height based on the heights of both parents. This calculation provides a rough estimate of potential growth, though actual height can vary due to other factors.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• Mother's height — Height of the mother in centimeters
• Father's height — Height of the father in centimeters
• 13 cm — Adjustment factor for male children

Explanation: The formula averages the parents' heights with an additional 13 cm for boys, then divides by 2.

3. Understanding Height Prediction

Details: While genetics play a major role in determining height, other factors like nutrition, health during childhood, and environmental factors can influence final adult height. The prediction typically has a margin of error of about ±5 cm.

4. Using the Calculator

Tips: Enter both parents' heights in centimeters. For most accurate results, use measured heights rather than self-reported heights.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this prediction?
A: The formula predicts within ±5 cm about 70% of the time. It's more accurate for populations than individuals.

Q2: Does this work for girls?
A: No, use a different calculator that subtracts 13 cm instead of adding for girls.

Q3: What if parents' heights are very different?
A: The child's height will typically fall somewhere between the parents' heights, often closer to the mid-parental height.

Q4: Can nutrition affect the result?
A: Yes, optimal nutrition can help a child reach their genetic potential, while poor nutrition may result in shorter stature.

Q5: When is adult height typically reached?
A: Most boys reach their full adult height by age 16-18, though some may continue growing into their early 20s.
