1. What is the Height Prediction Calculator?

The Height Prediction Calculator estimates a child's adult height based on the heights of their parents. It uses a scientifically validated formula that accounts for genetic factors in height determination.

2. How Does the Calculator Work?

The calculator uses the mid-parental height formula:

Where:

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

Explanation: This formula accounts for the fact that boys tend to be slightly taller than the average of their parents, while girls tend to be slightly shorter.

3. Accuracy of Height Prediction

Details: This method predicts adult height within about 5 cm (2 inches) for 95% of children. Actual height can be influenced by nutrition, health, and other genetic factors.

4. Using the Calculator

Tips: Enter both parents' heights in centimeters, select the child's gender. For best results, use the parents' adult heights (not their current heights if elderly).

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this prediction?
A: About 70% of children will be within 5 cm of the predicted height, but individual results may vary.

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

Q3: What if my child is already a teenager?
A: For children over 2 years old, bone age assessment provides more accurate predictions.

Q4: Does nutrition affect the result?
A: Yes, poor nutrition can result in heights significantly below genetic potential.

Q5: Can medical conditions affect height?
A: Yes, growth hormone deficiency or other medical conditions can impact final height.
