Waist to Hip Ratio Calculator estimates the dimensionless ratio of the circumference of the waist to that of the hips. Scroll down if you wonder what conclusion you might draw from your waist-hip ratio or how to measure waist and hips properly!
The waist-hip ratio or waist-to-hip ratio (WHR) is the dimensionless ratio of the circumference of the waist to that of the hips. This is calculated as waist measurement divided by hip measurement (W⁄H). For example, a person with a 30″ (76 cm) waist and 38″ (97 cm) hips has a waist-hip ratio of about 0.78.
The WHR has been used as an indicator or measure of health, fertility, and the risk of developing serious health conditions. WHR correlates with perceptions of physical attractiveness.
Waist-to-hip ratio (WHR) is one of several measurements your doctor can use to see if you’re overweight, and if that excess weight is putting your health at risk. Unlike your body mass index (BMI), which calculates the ratio of your weight to your height, WHR measures the ratio of your waist circumference to your hip circumference. It determines how much fat is stored on your waist, hips, and buttocks.
Not all excess weight is the same when it comes to your health risks. People who carry more weight around their midsection (an apple-shaped body) are at higher risk for heart disease, type 2 diabetes, and premature death than those who carry more of their weight in their hips and thighs (a pear-shaped body). Even if your BMI is within a normal range, your risk for disease may be increased.
According to the World Health Organization (WHO), a healthy WHR is:
- 0.9 or less in men
- 0.85 or less for women
In both men and women, a WHR of 1.0 or higher increases the risk for heart disease and other conditions that are linked to being overweight.
How do you calculate your WHR?
To calculate your WHR you simply need to measure your waist and your hips, using a tape measure (or a length of string and a ruler), and then perform a simple calculation (or use our calculator at the top of the page). In order to get an accurate figure, it is important to make sure you take your measurements in the right place. For a full explanation, see our article on waist-to-hip ratio. There’s also links to how-to lists for measuring both your waist and hips below.
- Measuring your waist: use your tape measure to measure midway between your lowest rib and the top of your hips – it should be the part just above your belly button.
- Measuring your hips: measure at the widest point around the buttocks. Again, hold the tape snugly but don’t pull it in, and make sure it’s level all the way around.
