Risk categories follow WHO thresholds (men 0.90 / 0.99, women 0.80 / 0.84). The ratio is unit-independent. This is a screening estimate, not a diagnosis.

About Waist-to-Hip Ratio Calculator

The waist-to-hip ratio calculator divides your waist circumference by your hip circumference to produce WHR, a simple screening number for how your body stores fat. Because it is a ratio, it works identically in centimeters or inches.

Your result is placed into the World Health Organization risk categories, which differ by sex: for men, low risk below 0.90 and high risk above 0.99; for women, low risk below 0.80 and high above 0.84, with moderate in between. The tool also names your body-shape type — pear, with fat carried lower, or apple, with fat concentrated around the waist.

Abdominal fat correlates with cardiovascular and metabolic risk more strongly than overall weight, which is why WHR complements BMI. The calculator is free and instant in your browser.

How to use Waist-to-Hip Ratio Calculator

  1. Select your sex and units (metric or imperial).
  2. Measure and enter your waist circumference at its narrowest point.
  3. Measure and enter your hip circumference at the widest point.
  4. Read your waist-to-hip ratio, WHO health-risk category and body-shape type.

Frequently asked questions

Measure the waist at its narrowest point, usually just above the navel, after a normal exhale. Measure the hips at the widest part of the buttocks. Keep the tape level and snug, not tight.

By WHO thresholds, below 0.90 for men and below 0.80 for women is low risk. Ratios above 0.99 (men) or 0.84 (women) fall in the high-risk category used by this calculator.

Apple shapes store more fat around the abdomen, which is more metabolically active and linked to higher cardiovascular risk. Pear shapes carry fat lower on the hips and thighs, which is less risky.

They answer different questions: BMI gauges overall weight for height, while WHR captures fat distribution. Someone with a normal BMI can still have a high-risk WHR, so the two are best used together.

Not by itself. WHR is a screening estimate, not a diagnosis — measurement technique, build and muscle mass all influence it. Discuss persistent high readings with a healthcare professional.
