Free CDC reference calculator
Height percentile, with the context left in.
Compare one standing-height measurement with the CDC stature-for-age reference for ages 2 to 20. It describes where the measurement sits in a population reference; it does not predict final adult height.
CDC stature-for-age reference
Find the height percentile.
Enter age and standing height for ages 2 to 20.
Your reference result will appear here.
Age, height and the selected CDC chart all affect the percentile.
Stature-for-age percentile
Read the result
A percentile is a position, not a grade.
50th percentileThe measurement is near the center of the selected CDC age-specific reference.
3rd or 97th lineThese are reference-chart boundaries, not automatic diagnoses. A clinician interprets them with the full growth pattern.
One pointMeasurement quality and the pattern across time matter more than an isolated result.
Method and source
Built from the CDC stature-for-age LMS tables.
The calculator interpolates the CDC LMS reference by age in months, then converts the height into a z-score and percentile. It supports the male and female CDC chart references from age 24 through 240 months.
For educational use only. If a measurement or growth pattern concerns you, speak with a pediatrician or qualified clinician.
