Frequently Asked Questions
What is waist to hip ratio?▾
WHR = waist circumference ÷ hip circumference. A higher ratio indicates more abdominal (central) fat, which is associated with higher cardiovascular and metabolic risk.
Where do I measure my waist?▾
Measure at the narrowest point of the torso, usually between the lower ribs and the navel. Do not suck in — measure at a natural relaxed breath.
Why is WHR better than just waist size?▾
WHR accounts for body frame — a person with a 90cm waist but 115cm hips has different risk than someone with 90cm waist and 90cm hips. Absolute waist alone doesn't capture this.
