Enter the waist and hip circumferences into the calculator to determine the waist-to-hip ratio (WHR). This calculator converts units as needed and computes WHR, which can be an indicator of body-fat distribution and is associated with certain health risks.

Waist-to-Hip Ratio (WHR) Formula

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

\mathrm{WHR}=\frac{WC}{HC}

Variables:

  • WHR is the waist-to-hip ratio (unitless)
  • WC is the waist circumference (any length unit)
  • HC is the hip circumference (same length unit as WC)

To calculate WHR, divide the waist circumference by the hip circumference.

What is Waist-to-Hip Ratio (WHR)?

Waist-to-hip ratio (WHR) is a measurement used to assess body-fat distribution. A larger WHR (more weight carried around the waist relative to the hips) is associated with a higher risk of conditions such as cardiovascular disease, type 2 diabetes, and metabolic syndrome. Maintaining a healthy WHR through diet, exercise, and overall weight management can help reduce these risks.

How to Calculate Waist-to-Hip Ratio (WHR)?

The following steps outline how to calculate WHR.

  1. First, measure the waist circumference (WC) using a tape measure (commonly measured midway between the lowest rib and the top of the hip bone).
  2. Next, measure the hip circumference (HC) at the widest part of the hips/buttocks.
  3. Use the formula WHR = WC / HC (make sure WC and HC are in the same unit).
  4. Finally, compare your WHR with the calculator above to verify your results.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Waist circumference (WC) = 36 in

Hip circumference (HC) = 40 in

WHR = WC / HC = 36 / 40 = 0.90
