1. What is the Height Prediction Formula?

The height prediction formula estimates a child's adult height based on the parents' heights and the child's gender. It provides a rough estimate of genetic height potential, though environmental factors also play a significant role.

2. How Does the Calculator Work?

The calculator uses the mid-parental height formula:

Where:

• Mother's Height — Height of biological mother in cm
• Father's Height — Height of biological father in cm
• Adjustment — +13 cm for boys, -13 cm for girls

Explanation: The formula accounts for average height differences between genders by applying the adjustment factor before averaging the parents' heights.

3. Importance of Height Prediction

Details: While not definitive, height prediction can help identify potential growth disorders when actual growth significantly deviates from predictions. It's also useful for parental curiosity and planning.

4. Using the Calculator

Tips: Enter both parents' heights in centimeters, select the child's gender. For most accurate results, use the parents' adult heights.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this prediction?
A: The prediction has a margin of error of about ±10 cm. Genetics account for 60-80% of height, with nutrition and health affecting the rest.

Q2: Can I use feet and inches instead of cm?
A: The calculator uses cm for precision. Convert feet/inches to cm (1 foot = 30.48 cm, 1 inch = 2.54 cm) before entering values.

Q3: Does this work for all ethnicities?
A: The formula works best for populations with similar genetic backgrounds. Some ethnic groups may need different adjustment factors.

Q4: What if parents are very tall or short?
A: The formula becomes less accurate at extremes of height due to regression toward the mean.

Q5: Can this predict height at a specific age?
A: No, this only predicts final adult height. Growth charts are needed for age-specific height predictions.
