How do I use the Waist-to-Hip Ratio Calculator?

Select your gender - risk thresholds differ for men and women. Measure your waist at the narrowest point and hips at the widest, then enter both. You'll get your ratio and whether it falls in the healthy, moderate, or high risk range.

Is the Waist-to-Hip Ratio Calculator free?

Yes, the Waist-to-Hip Ratio Calculator on ToolHaven is completely free to use. No signup or registration is required.

Waist-to-Hip Ratio Calculator

Waist-to-hip ratio is a simple measure of where your body stores fat - and it's a better indicator of health risk than BMI alone. Enter your waist and hip measurements to see your ratio and risk level.

Waist-to-hip ratio (WHR) divides your waist circumference by your hip circumference. According to WHO guidelines, a WHR above 0.90 for men or 0.85 for women indicates abdominal obesity, which is associated with higher risk for cardiovascular disease, type 2 diabetes, and metabolic syndrome. This measure captures how fat is distributed - not just how much total fat exists.

WHR is considered a better predictor of metabolic health than BMI for many people. Someone can have a normal BMI with most fat stored centrally (apple shape), putting them at higher risk than their weight suggests. Conversely, a person with a high BMI but fat distributed around hips and thighs (pear shape) faces lower metabolic risk. Measuring both BMI and WHR together gives a more complete picture.

Frequently Asked Questions

How do I measure my waist correctly?

Measure at the narrowest point between your ribs and hip bone, usually just above the belly button. Breathe out normally, relax (do not suck in), and measure with the tape snug but not compressing the skin.

How do I measure my hips correctly?

Measure at the widest point around the buttocks - typically around the hip joints. Stand with feet together and hold the tape level all the way around.

Is WHR more useful than waist circumference alone?

For most clinical purposes, waist circumference alone is actually simpler and almost as useful. WHO action thresholds are over 80cm for women and over 94cm for men. WHR adds nuance by controlling for overall body frame size, which can be useful for comparing across different body types.
