1. What is the Height Prediction Formula?

The height prediction formula estimates a child's adult height based on the parents' heights, with a gender-specific adjustment. This method is commonly known as the mid-parental height calculation.

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 genetic height potential from both parents with gender-specific adjustments.

3. Accuracy of Height Prediction

Details: This method predicts height within ±10 cm in 95% of cases. Nutrition, health, and other environmental factors can affect actual height.

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 is about 68% accurate within ±5 cm and 95% accurate within ±10 cm.

Q2: Can this predict height for adopted children?
A: No, this method requires biological parents' heights for accurate prediction.

Q3: What if my child is already taller than the prediction?
A: Children may exceed predictions due to better nutrition, health, or other genetic factors.

Q4: Does this work for all ethnicities?
A: The formula works best for populations of European descent. Other ethnicities may need different adjustments.

Q5: Can I use feet and inches instead of centimeters?
A: The calculator uses cm for precision. Convert feet/inches to cm (1 foot = 30.48 cm, 1 inch = 2.54 cm).
