About this calculator

Percentiles and SDS for length/height, weight, BMI (from 2 years) and weight for length/height according to the Swiss reference of Eiholzer et al. 2025. It is the basis of the growth charts 2026 that pädiatrie schweiz has recommended since 2026-06-15. Head circumference, BMI under 2 years and birth measurements are not part of this reference; pädiatrie schweiz names other sources for these.

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.

Frequently asked questions

What data underlie the Swiss growth curves 2026?

Measurements of 43 290 children and adolescents from pediatric practices, schools and military recruitment (data 2019 and 2025). The curves are smoothed with the LMS method; L, M and S are given in the supplement of the article (Eiholzer et al., J Clin Med 2025).

Why are head circumference and BMI missing under 2 years?

These measurements are not part of the study by Eiholzer 2025. pädiatrie schweiz uses other sources for them: head circumference according to Prader 1989 and KiGGS, BMI under 2 years according to WHO, measurements at birth according to Voigt 2006. The official chart sheets are available from pädiatrie schweiz.
