Enter the waist and chest circumference measurements into the calculator to determine the waist to chest ratio. This ratio is a measure of body fat distribution and can be an indicator of health risks.

Waist to Chest Ratio Formula

The following formula is used to calculate the waist to chest ratio.

WCR = Waist / Chest

Variables:

  • WCR is the waist to chest ratio
  • Waist is the circumference of the waist (inches)
  • Chest is the circumference of the chest (inches)

To calculate the waist to chest ratio, divide the waist circumference by the chest circumference.

What is a Waist to Chest Ratio?

The waist to chest ratio (WCR) is a simple measure used to assess the distribution of body fat. It is calculated by dividing the waist circumference by the chest circumference. A lower ratio typically indicates a more favorable body fat distribution and can be associated with a lower risk of cardiovascular diseases and other health issues. This ratio is often used in fitness and health assessments.

How to Calculate Waist to Chest Ratio?

The following steps outline how to calculate the Waist to Chest Ratio.


  1. First, measure the circumference of the waist at the narrowest point.
  2. Next, measure the circumference of the chest at the widest point, typically around the nipples.
  3. Use the formula WCR = Waist / Chest.
  4. Finally, calculate the Waist to Chest Ratio (WCR).
  5. After inserting the measurements and calculating the result, check your answer with the calculator above.
