How to Calculate Waist-to-Hip Ratio

Waist-to-hip ratio is another health measurement that can be used to help estimate body fat and healthy weight.

This calculation can tell you if you are carrying excess weight around your belly. Fat in the midsection, also called visceral fat, can cause various health problems. For example, studies have correlated high amounts of abdominal fat with worsening cardiovascular risk factors.[1]

Additionally, a high waist circumference is associated with metabolic syndrome and type 2 diabetes.[2]

Metabolic syndrome is a constellation of findings that include central adiposity (measured by increased waist circumference), glucose intolerance, dyslipidemia, and high blood pressure. By calculating your waist-to-hip ratio, you can determine if you are at a higher risk for these health issues.

Waist-to-hip ratio is also noted to be an indicator of obesity. In fact, studies have found that this ratio is a better marker for obesity than BMI alone.[3]

Waist-to-Hip Ratio Formula

The value is exactly what it sounds like. You take your waist circumference and divide this by your hip circumference. Since this is a ratio, it doesn’t matter if you use centimeters or inches, as long as you use the same units for each measurement.

waist-to-hip ratio = waist circumference / hip circumference

The value obtained can be compared to a reference chart to determine your health risk status. A higher ratio indicates a higher level of abdominal fat and increased risk of chronic disease.

How and Where to Measure Waist

To measure your waist circumference, stand up tall and exhale fully. Then use a tape measure to measure your waist just above your navel. This is the point where your waist is the smallest.

How and Where to Measure Hips

For your hip circumference measurement, stand up straight and wrap the tape measure around the widest part of the hips as viewed from the side.

For both the waist and hip measurements, be sure not to pull the tape measure too tight and take the measurement where the ends of the tape measure overlap.

Healthy Waist-to-Hip Ratio

According to the World Health Organization, healthy waist-to-hip ratios are as follows:[4]

Table showing the health risk status for waist-to-hip ratios in men and women according to the World Health Organization.
Health Risk Status Men Women
Low < 0.95 < 0.80
Medium 0.96-1.0 0.81-0.85
High >1.0 >0.86

There are a number of factors that play a role in healthy body composition. When combined with other indices, such as BMI and body fat percentage, the waist-to-hip ratio is a very useful tool in determining overall health and fitness and disease risk.
