1. What is the Boys' Height Prediction Formula?

The boys' height prediction formula estimates a boy's adult height based on the heights of both parents. It accounts for genetic factors that influence growth potential.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• Father's Height — Biological father's height in centimeters
• Mother's Height — Biological mother's height in centimeters
• 13 — Constant adjustment factor for boys

Explanation: The formula averages the parents' heights with an additional 13cm for boys, then divides by 2 to account for genetic inheritance from both parents.

3. Importance of Height Prediction

Details: Height prediction can help parents and pediatricians monitor a child's growth pattern and identify potential growth disorders early.

4. Using the Calculator

Tips: Enter both parents' heights in centimeters. The calculator works best when both parents are biological relatives and of average height.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this prediction?
A: The prediction is about 68% accurate within ±5 cm and 95% accurate within ±10 cm, as genetics account for about 60-80% of height variation.

Q2: What other factors affect height?
A: Nutrition, health during childhood, hormonal factors, and environmental conditions can all influence final adult height.

Q3: When can you predict a child's adult height?
A: Predictions become more reliable after age 4, but this calculator provides a genetic potential estimate at any age.

Q4: Is there a different formula for girls?
A: Yes, the girls' formula uses -13 instead of +13 in the numerator.

Q5: What if parents are very tall or short?
A: The formula works best for average height parents. Extreme heights may require additional considerations.
