What’s your child’s height percentile?
A reference for parents and caregivers: enter a measurement from a checkup and see where it lands on the CDC growth charts pediatricians use. Everything computes in your browser; nothing you type is sent anywhere.
The measurement
Result
Percentiles are descriptive statistics of public survey data — not advice, and not a judgment. Survey estimates carry sampling error, largest in the far tails.
Questions people ask
Who is this page for?
Parents and caregivers. It is a reference for adults who want to understand a measurement from a checkup — it is not directed to children, collects nothing, and shows no personalized content.
Whose growth curves are these?
The CDC 2000 growth charts — the same stature-for-age curves pediatricians plot at checkups — covering ages 2 through 20, using the CDC’s published LMS parameters exactly.
Is a low or high percentile a problem?
A percentile is a position, not a verdict — healthy children grow all along the curve. Questions about your child’s growth belong to your pediatrician, not a website.
Do you do adult height?
Not yet. The CDC growth charts end at 20; an adult version based on the CDC’s NHANES survey is on the roadmap and will be labeled when it lands.
