Step-by-Step Calculation
Predicted Adult Height: 179 cm (5'10")
This child is predicted to reach an adult height of approximately 179 cm, with a typical range between 170.5 cm and 187.5 cm. The actual height may vary based on nutrition, health, and other factors.
Disclaimer: This example demonstrates the mid-parental height calculation method. Results are estimates and individual outcomes may vary significantly based on genetic, nutritional, and environmental factors.
How Height Prediction Works
Mid-Parental Height Method
The most widely used method for predicting adult height, based on parental genetics:
- Average both parents' heights
- Add 6.5 cm (2.5 inches) for boys
- Subtract 6.5 cm (2.5 inches) for girls
- Apply ±8.5 cm genetic variation range

Growth Percentile Analysis
Our calculator also provides growth percentile analysis when current height and age are provided. This compares your child's height to standardized growth charts, showing how they rank compared to other children of the same age and gender.
Height Calculator FAQ
When is the best time to predict a child's height?
Height predictions can be made at any age, but accuracy improves after age 2-4 when growth patterns stabilize. The mid-parental height method remains consistent throughout childhood and provides reliable estimates for adult height.
What factors can affect final adult height?
While genetics account for about 80% of height, other factors include nutrition during growth years, overall health, hormone levels, sleep quality, physical activity, and environmental factors. Chronic illnesses or nutritional deficiencies can impact growth potential.
How accurate are height predictions?
The mid-parental height method is accurate within 2-4 inches (5-10 cm) for approximately 95% of children. This represents two standard deviations from the predicted height. Individual results may vary based on genetic factors and environmental influences.
What do height percentiles mean?
Height percentiles indicate how a child's height compares to peers of the same age and gender. For example, the 75th percentile means the child is taller than 75% of children their age. Percentiles between 5th and 95th are generally considered normal range.
Can nutrition affect predicted height?
Yes, proper nutrition during critical growth periods is essential for reaching genetic height potential. Adequate protein, calcium, vitamins, and overall caloric intake support optimal growth. Malnutrition can prevent children from reaching their predicted adult height.
