Child Growth Comparison · CDC US Reference

Record a child’s height and weight over time and compare the measurements with one selected reference. Choose that reference knowingly; your language or location does not select it for you.

Birth date and measurements stay in this browser and are not uploaded or saved.

BMI-for-age trend

Dots show each BMI percentile. The graph is a visual comparison, not a diagnosis.

How to use it

Choose the CDC United States reference, enter the reference sex category, birth date and measurement date, then add each height and weight measurement. The page plots BMI-for-age, stature-for-age and weight-for-age percentiles locally.

How the chart works

The bundled CDC 2000 LMS tables cover ages 2–20 years. Exact dates determine age; the CDC table uses monthly age bands. BMI above the 95th percentile uses the CDC extended method and its 2022 dispersion data. This compares measurements with a US reference population; it is not a country-specific or universal standard.

Common questions

Is the CDC reference right for every country?

These curves describe the United States reference population. Use the comparison only if it is useful to you; the tool does not infer a standard from your language or location.

Can I use it for a child younger than two years?

This tool starts at age two. WHO has a separate standard for younger children; CDC recommends it in the United States. We do not substitute CDC values for that age range.

Does a percentile diagnose a condition?

A percentile is one point of comparison. A clinician interprets growth over time along with health history and other information.

Why does a high BMI use another method?

CDC recommends the 2022 extended BMI-for-age method for very high values above the 97th percentile. This tool uses the published CDC extended calculation above the 95th percentile and does not give an exact percentile above BMI 60.

Scope and limits

For children aged 2 through 20 only. Prematurity, clinical diagnosis, treatment advice, adult BMI thresholds and WHO infant standards are not supported. The CDC reference and methods were developed for the United States; use local clinical guidance. A percentile alone does not explain health or growth. The source material is free on the CDC website; CDC does not endorse this tool.
