Waist Circumference Health Risk Calculator
Classify your waist circumference against WHO cardiometabolic risk thresholds.
A general screening tool, not a diagnosis — talk to a healthcare provider about your overall cardiometabolic risk profile.

A single measurement, no math required
The WHO's thresholds — 94cm and 102cm for men, 80cm and 88cm for women — work directly on a raw waist measurement, no ratio or calculation needed, unlike our waist-to-hip or waist-to-height ratio tools. The thresholds differ by sex because men and women naturally carry different amounts of abdominal fat at the same overall body size, so the same absolute measurement doesn't carry the same risk for both.
Frequently asked questions
What are the WHO waist circumference risk thresholds?
Commonly cited thresholds flag increased risk above 94cm (37in) for men and 80cm (31.5in) for women, with substantially increased risk above 102cm (40in) for men and 88cm (34.5in) for women.
Why measure waist circumference instead of relying on BMI alone?
Waist circumference reflects abdominal fat specifically, which is more strongly linked to cardiometabolic risk (like type 2 diabetes and heart disease) than overall body weight — two people with the same BMI can have very different waist measurements and different risk levels.
