About this calculator

Percentiles and z-score for weight-for-age, length-for-age, head-circumference-for-age and weight-for-length according to the CDC 2000 curves for infants (0–36 months).

In preterm infants, if a gestational age is given, age is corrected up to month 24 of life for the missing weeks up to 40+0. The z-score (SDS) describes the deviation from the median in standard deviations; the percentile the proportion of the reference population with a smaller value.
