Growth & percentiles
17 calculators · WHO, CDC, and German references – weight, length, head circumference, BMI, growth velocity, final height, Bayley-Pinneau
Here you will find online calculators for percentiles, z-scores and growth assessment in children and adolescents. Included are the WHO Child Growth Standards 2006 (0–24 months and 0–5 years), the WHO reference 2007 (5–19 years), CDC 2000, extended CDC BMI percentiles 2022, the German Kromeyer-Hauschild reference 2001 and KiGGS (RKI). In addition there are calculators for growth velocity, weight gain, height age and final height predictions according to Bayley-Pinneau 1952 and Paley 2004. They support the interpretation of measurements in practice and in the clinic. Each calculator states its formula and sources.

Frequently asked questions
Which percentile curves apply in Germany and Austria?
The Kromeyer-Hauschild calculator (German reference 2001) provides percentiles and SDS for weight, height and BMI from 0 to 18 years. It is the reference commonly used in Germany and Austria and the basis of the obesity guideline (AGA).
How do I calculate growth velocity in cm per year?
The Growth Velocity calculator computes cm/year from two height measurements and compares the value with the median increment of the selected reference (WHO, CDC, Kromeyer-Hauschild or KiGGS) in the same age interval. The z-score and percentiles of both measurements are also output.
How can a child's adult height be estimated?
The Adult Height from Parental Height calculator gives the most likely adult height together with the 50/80/95% range. Alternatively, the Bayley-Pinneau method 1952 using bone age and the Paley multiplier method 2004 without an X-ray are available.
