Universal calculators
3 calculators · one measurement against every reference curve, bulk CSV, curve generator
Here you will find the universal calculators for growth data: the growth calculator for a single measurement against a selectable reference curve, the bulk calculator for CSV mass data and the generator for custom growth curves with freely selectable percentile or z-score lines. The universal calculator reaches all references of the growth engine, including CDC, WHO, Fenton, Olsen, Zemel, Brooks, Cappa, Addo, Abdel-Rahman, Mramba, Kromeyer-Hauschild and KiGGS. The output is z-score, percentiles, median and growth curve; results can be used as a table, CSV or SVG. Each calculator states its formula and sources.

Frequently asked questions
How do I calculate z-score and percentiles for several patients at once?
The bulk calculator takes CSV data with sex, age or gestational age and measured value and calculates the z-score and percentiles for all rows against a selected dataset. The result appears as a table and as a CSV download.
How do I create a growth curve with custom percentile lines?
The curve generator produces the growth curve of a selected dataset as an SVG, with freely selectable percentile or z-score lines and a selectable axis range. The curve is suitable for printing or embedding.
