Waist-Hip Ratio (WHR) Calculator
The Waist-Hip Ratio (WHR) is a quick and simple measure used to assess body fat distribution. It's calculated by dividing your waist circumference by your hip circumference. This ratio can indicate potential health risks associated with excess abdominal fat, which is often linked to conditions like heart disease, diabetes, and stroke, even in individuals with a healthy Body Mass Index (BMI).
How to Measure Correctly:
- Waist Circumference: Measure around the narrowest part of your waist, usually just above your belly button. Ensure the tape measure is snug but not compressing your skin. Measure after exhaling.
- Hip Circumference: Measure around the widest part of your hips and buttocks.
- Ensure you use the same unit of measurement (either centimeters or inches) for both waist and hip measurements.

Understanding Your WHR:
The interpretation of WHR varies slightly between men and women:
- For Women:
- Below 0.80: Low health risk (pear shape)
- 0.80 – 0.84: Moderate health risk
- 0.85 and above: High health risk (apple shape)
- For Men:
- Below 0.90: Low health risk (pear shape)
- 0.90 – 0.99: Moderate health risk
- 1.00 and above: High health risk (apple shape)
A higher WHR indicates a greater proportion of fat stored around the abdomen (apple shape), which is associated with higher health risks compared to fat stored around the hips (pear shape).
Example Calculation:
Let's say a woman has a waist circumference of 75 cm and a hip circumference of 90 cm.
WHR = Waist / Hip = 75 cm / 90 cm = 0.83
According to the guidelines for women, a WHR of 0.83 falls into the moderate health risk category.
