Estimate a child's possible adult height using the mid-parental height method. Enter the biological parents' heights and choose the child's sex for a simple target-height range.
Enter height details
Result
Enter both parents' heights to estimate the child's target adult height.
Use accurate measurements
Measure without shoes, on a hard floor, standing straight against a flat wall for the most useful input.
Track the growth pattern
A series of measurements plotted over time is more informative than one isolated height reading.
Expect a broad range
The mid-parental method is a simple estimate. Many healthy children finish several inches above or below it.
Frequently asked questions
How does the child height calculator work?
It averages the biological parents' heights and applies a small sex-based adjustment. For boys, about 2.5 inches is added; for girls, about 2.5 inches is subtracted.
How accurate is the estimate?
It is only a rough target. A commonly used range is approximately 4 inches, or about 10 cm, above or below the estimate.
Can current child height improve the prediction?
Growth charts, growth velocity, puberty stage, and bone-age assessment can provide more context. A pediatrician can interpret these factors.
When should parents seek medical advice?
Ask a pediatrician if the child is crossing growth-chart percentiles, growing much more slowly than before, or if there are other health or puberty concerns.
