Enter your waist and hip circumference into the calculator below to determine your waist-to-hip ratio.

Waist To Hip Ratio Formula

The following formula is used to calculate the waist-to-hip ratio.

W-H = W/H
  • Where W-H is the ratio
  • W is the waist circumference (in)
  • H is the hip measurement (in)

To calculate the waist-to-hip ratio, divide the waist circumference by the hip measurement.

Waist-to-Hip Ratio

A waist-to-hip ratio is a measure of the ratio of the circumference around your waist to the circumference around your hip.

What is Waist to Hip Ratio Used For?

In this case, the formula is a simple division since the resulting value is just a ratio of one measure to another. In general, a larger waist-to-hip ratio means a higher body fat. That's because while the hip measurement of a human rarely changes, the waist measurement increases as your body fat increase. This is due to the simple fact that human bodies store fat in the waist. As mentioned previously, since the human body does not typically store fat directly on the hips, the hips circumference measurement is not significant. It's also important to note that this ratio can be highly influenced by genetics, so it does not make much sense to compare ratios from person to person. It's better to use the ratio as a gauge for losing or gaining body fat.

How to calculate waist to hip ratio?

How to calculate waist to hip ratio?

  1. First, measure your hip circumference.

    This will be the location where you can feel your hip bones about 2 inches below your belly button.

  2. Next, measure your waist circumference.

    This will be about even with your belly button.

  3. Finally, calculate your ratio.

    Using the equation above, calculate your waist to hip ratio.


What is a healthy waist-to-hip ratio?
A healthy waist-to-hip ratio is generally considered to be below 0.9 for men and below 0.85 for women. These values are associated with a lower risk of heart disease and other health conditions related to obesity.

Can waist-to-hip ratio predict health outcomes better than BMI?
Yes, in some cases, the waist-to-hip ratio can be a better predictor of certain health outcomes, such as cardiovascular disease and type 2 diabetes, than Body Mass Index (BMI). This is because it specifically measures abdominal fat, which is a key risk factor for these conditions.

How often should I measure my waist-to-hip ratio?
It's recommended to measure your waist-to-hip ratio regularly, about once every six months, to monitor changes in your body composition and assess your risk for health conditions. However, if you are actively trying to lose weight or change your body composition, you might want to measure it more frequently.
