Waist Circumference Calculator
Waist size is a quick marker of abdominal fat, which carries more health risk than fat elsewhere. Measure around your waist at the navel and compare it with the WHO thresholds for your sex.

| Level | Men |
|---|---|
| Low risk | below 94 cm (37 in) |
| Increased risk | 94-102 cm (37-40 in) |
| High risk | over 102 cm (40 in) |
What the thresholds mean
The WHO links waist size to metabolic risk. For men, risk is increased above 94 cm (37 in) and high above 102 cm (40 in). For women, increased above 80 cm (31.5 in) and high above 88 cm (34.5 in). Abdominal (visceral) fat is more strongly tied to heart disease and diabetes than fat on the hips or thighs.
How to measure
Stand relaxed and wrap a tape around the waist at the level of the navel, snug but not compressing the skin, and breathe out normally before reading. Waist size complements BMI: two people with the same BMI can carry very different amounts of abdominal fat.
