Heath-Carter Somatotype Calculator

Determine your clients' body type by calculating the three somatotype components: endomorphy, mesomorphy and ectomorphy. Get a classification and personalized training recommendations based on the Heath-Carter method.

How to use this calculator

Enter height (cm), weight (kg), 4 skinfold measurements (mm), 2 bone diameters (cm) and 2 circumferences (cm) to calculate the full somatotype using the Heath-Carter method. Use a calibrated skinfold caliper and a sliding bone caliper.

Basic data

Skinfold measurements (mm)

Measure with a skinfold caliper on the right side of the body. Take 2-3 measurements for each skinfold and use the average.

Bone diameters (cm)

Measure with a sliding bone caliper. Measure the biepicondylar diameter of the humerus and femur.

Circumferences (cm)

Measure with a flexible tape measure. The arm should be flexed and contracted; the calf at its widest point.
