Predicted Adult Height
Estimated Height: cm
Range: cm (± 10 cm)
How to Use the Height Calculator
A Height Calculator is a tool designed to estimate a child’s future adult height based on the parents’ heights and gender. While genetics play the most important role in growth, this calculator provides a rough prediction using a widely accepted mid-parental formula.
What the Height Calculator Does
The calculator uses the mid-parental height formula, which averages the parents’ heights and adjusts slightly based on the gender of the child. It then provides both a predicted height and a possible range (±10 cm), since many other factors—like nutrition, environment, exercise, and health—can influence growth.
- For boys:
(Father’sheight+Mother’sheight+13)÷2(Father’sheight+Mother’sheight+13)÷2 - For girls:
(Father’sheight+Mother’sheight−13)÷2(Father’sheight+Mother’sheight−13)÷2
The “13 cm” adjustment accounts for the average height difference between adult men and women.
How to Use the Calculator
- Enter the father’s height in centimeters.
Example:180 cm. - Enter the mother’s height in centimeters.
Example:165 cm. - Select the child’s gender from the dropdown menu (Male or Female).
- Click the “Calculate Predicted Height” button.
- The calculator will display:
- The estimated adult height.
- A range of possible outcomes (±10 cm) to show natural variation.
Example Calculation
- Father’s height: 180 cm
- Mother’s height: 165 cm
- Gender: Male
Formula:
(180+165+13)÷2=179cm(180+165+13)÷2=179cm
Predicted adult height: 179 cm
Range: 169 – 189 cm
Important Notes
- This is a prediction tool, not an absolute guarantee.
- Growth can be influenced by genetics, nutrition, sleep, physical activity, and health conditions.
- Children may grow taller or shorter than the estimate, but this method provides a reasonable expectation.
FAQ: Height Calculator
Q1: How accurate is the height calculator?
A: It’s a rough estimate. Most children will end up within ±10 cm of the predicted height, but genetics and lifestyle can cause variations.
Q2: Why does gender matter?
A: On average, men are about 13 cm taller than women. The formula adjusts for this difference when estimating.
Q3: Can nutrition and exercise affect final height?
A: Yes. Good nutrition, regular physical activity, and healthy sleep patterns can help children reach their maximum potential height.
Q4: What if my child’s predicted height seems much lower or higher than expected?
A: Remember that this is a statistical formula. Individual differences, genetics from grandparents, or growth conditions may play a role.
Q5: Is this a medical tool?
A: No. This calculator is educational and for general guidance only. For concerns about growth, consult a pediatrician or endocrinologist.
Q6: Can I use this calculator for adults?
A: No, it’s specifically designed to estimate children’s adult height before they reach physical maturity.
