Standard Charts

The WHO curves are a combination of the 2006 international growth standard for breastfed babies (0-5 years) and the 2007 standard for older children (5-19 years). The WHO curves are usually the best choice for babies.

Weight	0 - 10 years
Height	0 - 19 years
Head Circumference	0 - 5 years
Weight vs. Height	45 - 120 cm
BMI	0 - 19 years

A Note on Weight: The WHO weight vs. age data set only goes to 10 years of age (see complete explanation here). The stated reason for this is quoted below. Above the age of 10, using BMI is recommended instead of just weight as a more accurate measure of health.

Weight-for-age reference data are not available beyond age 10 because this indicator does not distinguish between height and body mass in an age period where many children are experiencing the pubertal growth spurt and may appear as having excess weight (by weight-for-age) when in fact they are just tall.

The CDC curves are a 2000 growth reference based on a mix of breastfed and formula-fed babies in the US. Doctors in the US usually switch to this curve at age 2. The WHO-CDC combo chart uses the WHO charts up to age 2 and the CDC charts above that.

Weight	0 - 20 years
Height	0 - 20 years
Head Circumference	0 - 3 years
Weight vs. Height	45 - 121.5 cm
BMI	2 - 20 years

The Fenton curves are a 2013 growth reference for premature infants. These charts are measured in gestational age and go from 24 to 48 weeks. The Preterm-WHO combo chart uses the Fenton curves up to a gestational age of 48 weeks, and the WHO curves above that.

Weight	24 - 48 gestational weeks
Height	24 - 48 gestational weeks
Head Circumference	24 - 48 gestational weeks

Country-Specific Charts

Due to licensing restrictions these curves are only available in the pro version of the app.

Height	33 gestational weeks - 23 years
Head Circumference	23 gestational weeks - 17 years
BMI	33 gestational weeks - 23 years

Weight	16+ years
BMI	16+ years

Notes

A Note on Height: You will see a small jump in many of the height-based curves (height, weight vs. height, and BMI) at around age 2. This is because the curves switch from using recumbent length (laying down) to using stature (standing height) and stature is on average slightly different from recumbent length. The difference is small (less than 1 cm) but it is real (CDC explanation here), not a glitch in the app or the data sets.
