Convert Waist measurement
Converted—
Typical range: 75–95 cm for adult men, 65–85 cm for adult women (varies widely)
§ 01
How to measure
Stand relaxed with feet shoulder-width apart. Locate the natural waist — the narrowest point of the torso, typically halfway between the lowest rib and the top of the hip bone (iliac crest). Wrap a flexible tape horizontally around this point, ensuring it sits flat and level. Measure at the end of a normal exhale without sucking in.
§ 02
Tips for accuracy
- Measure at the natural waist, not at the navel or where pants sit
- Don't suck in; this defeats the purpose of the measurement
- Measure at the end of a normal exhale
- For health tracking, men's waist > 102 cm (40 in) and women's > 88 cm (35 in) indicate elevated cardiovascular risk
