About this calculator

Reference percentiles from the KiGGS study of the Robert Koch Institute (2003–2006): weight, height, BMI, head circumference, triceps and subscapular skinfold.

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.
