Your waist-to-hip ratio compares the size of your waist with the size of your hips. Enter both measurements to see your ratio and where it falls. This tool is for adult women, and nothing you enter is sent anywhere.
Calculate your ratio
How to measure
- Waist: stand relaxed and breathe out normally. Measure around your torso at the midpoint between your lowest rib and the top of your hip bone, usually just above the belly button.
- Hips: measure around the widest part of your hips and seat, keeping the tape level all the way around.
Use the same unit for both, and measure on bare skin or over thin clothing.
What the ratio means
For women, a ratio of 0.80 or lower is generally considered the lower-risk range, 0.81 to 0.85 is moderate, and above 0.85 is where the World Health Organization flags increased health risk linked to fat around the abdomen. The ratio is one indicator among many and is not a diagnosis. If you are curious about your result, your doctor can put it in context.

Frequently asked questions
What is a good waist-to-hip ratio for women?
A ratio of 0.80 or lower is generally considered the lower-risk range. The World Health Organization uses 0.85 and above as a sign of increased risk. Age, ethnicity, and genetics all play a part.
Is waist-to-hip ratio the same as body shape?
No. Body shape looks at bust, waist, and hips to guide styling, while waist-to-hip ratio is a single number often used as a health indicator.
Can my ratio change after menopause?
Yes. Fat often shifts toward the midsection after menopause, so your ratio can rise even if your weight stays about the same.
Does this replace medical advice?
No. It is a simple screening number. For guidance on your own health, talk to your doctor.
