What is this calculator?
Waist to hip is waist centimetres divided by hip centimetres. It is a simple shape check people use next to BMI. It does not diagnose heart disease or set a clothing size.
How it works
- Measure waist after a normal breath out, usually near the navel.
- Measure hips at the widest point.
- Read the ratio as a snapshot. Compare next month with the same tape spots.
Common questions
What is the waist to hip calculator?
It divides waist by hips. A shape check, not a diagnosis.
Is there an official UK cut-off?
Clinics talk about ratios, but your GP will also look at you, waist to height and other numbers.
Waist to height or waist to hip?
Waist to height is the simpler half-height check. Use both if you like. Neither replaces a GP.
Example scenarios
Liam, after a desk month
Waist 96 cm, hips 104 cm
Ratio about 0.92.
Ayesha, checking a goal
Waist 74 cm, hips 98 cm
Ratio about 0.76.
Understanding your results
One tape day is a snapshot. If the ratio is high and you have other concerns, take both numbers to a GP. The waist to height page is next door.
