Waist-to-Hip Ratio Calculator

This waist-to-hip ratio calculator finds your WHR by dividing your waist circumference by your hip circumference. It also compares your result with sex-specific abdominal obesity cutoffs commonly used in health screening: 0.85 or higher for women and 0.90 or higher for men.

Enter your waist and hip measurements to calculate your waist-to-hip ratio. The tool compares your result with sex-specific WHR abdominal obesity cutoffs.

How to measure your waist and hips

For the waist measurement, place the tape around the midpoint between your lowest rib and the top of your hip bone. For the hip measurement, place the tape around the widest part of your hips and buttocks. Keep the tape level, snug, and not pulled tight.

How to use the calculator

Select Woman or Man for the cutoff system.
Choose Metric or Imperial.

Waist-to-hip ratio formula

The formula is simple:

Waist-to-hip ratio = waist circumference ÷ hip circumference

The ratio has no unit. You can use centimeters or inches, as long as both waist and hip are measured in the same unit system.

What your result means

A higher waist-to-hip ratio means more body size is concentrated around the waist compared with the hips. This can be useful for screening central fat distribution. In this calculator, results at or above the selected cutoff are flagged as at or above the WHR cutoff.

Waist-to-hip ratio focuses on body fat distribution, not just total body size. BMI can miss differences in where body mass is carried, while WHR gives a quick look at waist size compared with hip size.
