14 calculators · mid-upper arm circumference, skinfolds, waist circumference, body fat
Here you will find calculators for the anthropometry of children and adolescents: z-score and percentiles for mid-upper arm circumference, skinfolds, waist circumference and body fat. Included are mid-upper arm circumference according to Abdel-Rahman 2017, Mramba 2017 and the WHO standards 2006, triceps and subscapular skinfolds according to WHO and Addo & Himes 2010, upper arm muscle and fat area, waist circumference, waist-to-height and waist-to-hip ratios (KiGGS reference, RKI 2013) and body fat estimation according to Slaughter 1988. The calculators are intended for interpreting measurements in practice. Each calculator states its formula and sources.

Frequently asked questions
Which reference should be used for mid-upper arm circumference in children?
That depends on age: the WHO mid-upper arm circumference applies from 3 months to 5 years, Abdel-Rahman MUAC (CDC) from 2 months to 18 years, Mramba MUAC from 5 to 19 years. Each calculator outputs z-score and percentiles.
How do I assess waist circumference in adolescents?
The waist circumference percentile calculator classifies the value against the German KiGGS reference percentiles (RKI 2013) for 11 to 18 years. In addition, the Waist-to-Height Ratio calculator computes the waist-to-height ratio and compares it with the cut-off 0.5.
How can body fat percentage be estimated from skinfolds?
The Body fat from skinfolds (Slaughter) calculator estimates body fat percentage from triceps and subscapular skinfolds or triceps and calf skinfolds according to Slaughter et al. 1988. The Skinfold sum calculator classifies the sum and the individual values against the KiGGS reference.
