Have you ever caught yourself squinting at your kid and wondering, “Will they tower over me someday?”
Our free kids’ height calculator offers a fun way to estimate how tall your child may be as an adult. Enter a few details below to see their predicted adult height.
The calculator uses a commonly used mid-parental height method, which considers both parents’ heights and a child’s sex assigned at birth. It’s an estimate, not a guarantee, but it can be pretty fun to see what the numbers say.

How Does the Kids’ Height Calculator Work?
Our child height predictor uses a mid-parental height formula to estimate adult height. The calculation combines each parent’s height, then adjusts the estimate based on whether the calculation is for a boy or girl. Mayo Clinic describes a similar approach for estimating a child’s future height.
Of course, a lot more goes into how tall a child eventually becomes. Genetics matter, but so can growth patterns, overall health, and the timing of puberty. Think of this as a fun, fascinating estimate — not a crystal ball.

How Accurate Is a Child Height Predictor?
A child height calculator is best used as a fun estimate, not a promise. Kids grow at different rates, and factors like genetics, health, nutrition, and puberty can all affect adult height. If you have questions about your child’s growth or development, their pediatrician is the best person to ask.
