CDC Growth Chart Calculator

Check your child's weight and height percentile using the official CDC 2000 growth reference — the standard most US pediatricians use for children ages 2 and up.

Infant Growth Percentile Calculator.

Enter your baby's measurements and location to see percentiles on the most appropriate growth chart for your region — with interactive curves, growth spurt indicators, and a printable report.

WHO is recommended for infants under 2 years globally. CDC is used by US pediatricians. Select a country above to auto-fill the best standard.

If born before 37 weeks, corrected age adjusts all percentiles until 24–36 months.

What the CDC growth chart measures

The CDC growth charts summarize how a large, nationally representative sample of US children grew between the 1960s and 1990s. Unlike the WHO standard, which is a prescriptive model of optimal growth, CDC charts are a descriptive reference — they tell you how American children of a given age and sex typically measured, not necessarily how they should.

For that reason, US pediatricians commonly switch to CDC charts once a child turns 2, and use them through adolescence for tracking weight, height, and BMI-for-age.

CDC vs WHO: the practical difference

Because the CDC dataset includes formula-fed infants (who tend to gain weight faster in the first year than exclusively breastfed babies in the WHO dataset), a baby's percentile can shift slightly when switching between the two charts. This is expected and not a sign of a problem — see our WHO vs CDC comparison for a full breakdown.
