Mid-Parental Height Formula:
| From: | To: |
The Mid-Parental Height Formula is a method to estimate a child's adult height based on the heights of the biological parents. It accounts for genetic influences on growth potential and provides a rough estimate of expected adult height.
The calculator uses the Mid-Parental Height equation:
Where:
Explanation: The equation accounts for average height differences between genders, with boys typically being taller than girls. The result represents the 50th percentile prediction.
Details: Height prediction helps assess whether a child's growth is following expected genetic potential, which can be useful in pediatric growth monitoring and identifying potential growth disorders.
Tips: Enter both parents' heights in centimeters, select the child's gender. The calculator will provide the estimated adult height with a range of ±8.5 cm (representing the 3rd to 97th percentiles).
Q1: How accurate is this prediction?
A: The prediction is accurate to within ±8.5 cm in 95% of cases, as genetics account for about 60-80% of height determination.
Q2: What other factors affect height?
A: Nutrition, health during childhood, hormonal factors, and environmental influences can all impact final adult height.
Q3: Can this predict height for adopted children?
A: No, this only works for biological children as it relies on genetic inheritance patterns.
Q4: At what age is this prediction most accurate?
A: While it can be used at any age, predictions become more reliable as a child gets older and their growth pattern emerges.
Q5: What if parents are of very different heights?
A: The prediction will be midway between the parents' heights adjusted for gender. Children may fall anywhere within the expected range.
