Differences between the Charts
Here are some of the differences you may notice with the
WHO growth charts:
Length-for-age:
Slightly more infants and children will plot in the
lower length-for-age percentiles.
Weight-for-age:
Fewer infants and children will be identified with
low weight-for-age, especially between 6 and 23
months of age.
Weight-for-length:
Slightly lower number of infants and children with
low weight-for-length.
Fewer infants and children with high weight-for-
length.
This bar graph compares the growth patterns between the CDC and WHO growth charts.

WHO growth standards are based on healthy children living in optimal conditions so
more extreme cutoffs are used to identify nutrition risk.
