1. What is the Mid-Parental Height Formula?

The Mid-Parental Height Formula is a simple method to estimate a child's adult height based on the heights of the biological parents. It accounts for the genetic influence on height while considering gender differences.

2. How Does the Calculator Work?

The calculator uses the Mid-Parental Height Formula:

Where:

• Father's Height — Biological father's height in centimeters
• Mother's Height — Biological mother's height in centimeters
• Offset — +13 cm for boys, -13 cm for girls

Explanation: The formula averages parental heights with a gender-specific adjustment. For boys, we add 13 cm (5 inches), while for girls we subtract 13 cm.

3. Importance of Height Prediction

Details: While not definitive, height prediction helps identify potential growth disorders and sets realistic expectations for child development. Actual height may vary ±10 cm from prediction.

4. Using the Calculator

Tips: Enter parents' heights in centimeters, select the child's gender. For most accurate results, use measured heights rather than reported heights.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this prediction?
A: The formula predicts within ±10 cm for 95% of children. Nutrition, health, and other factors also influence final height.

Q2: Can this predict height for adopted children?
A: No, this requires biological parents' heights. Without this, other methods like bone age assessment may be used.

Q3: Does this work for all ethnicities?
A: The formula works reasonably well across populations, though some ethnic-specific adjustments might improve accuracy.

Q4: When is the prediction most accurate?
A: Predictions are most reliable when made after age 4, as early growth patterns may not reflect genetic potential.

Q5: What if parents' heights are very different?
A: The child may fall anywhere between parents' heights, with the formula providing a statistical average estimate.
