About Waist Circumference Risk Calculator

Waist circumference is a direct proxy for visceral fat and predicts cardiometabolic risk independently of BMI. The commonly used thresholds are 94 and 102 cm for European men and 80 and 88 cm for women, lowered to 90 and 100 cm for South and East Asian men because risk appears at lower absolute waist sizes.

Formulas

European thresholds

men 94 cm increased, 102 cm high; women 80 cm and 88 cm

Asian thresholds

Assumptions and limits

The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
These figures are population-average estimates, not a medical assessment or diagnosis. Body composition equations carry errors of several percentage points, and healthy ranges vary with age, ethnicity, muscularity and medical history. Discuss weight or body composition goals with a qualified clinician or dietitian.

Frequently Asked Questions

Why do thresholds differ by ethnicity?

Because visceral fat accumulates at lower total body fat in South and East Asian populations, so metabolic risk appears at smaller waists.

Is waist better than BMI?

For predicting metabolic risk, generally yes. Using both together is better than either alone.
