Enter the waist and thigh circumferences into the calculator to determine the thigh to waist ratio. This ratio can be used as an indicator of body fat distribution.

Thigh to Waist Ratio Formula

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

TWR = TC / WC

Variables:

  • TWR is the thigh to waist ratio
  • TC is the thigh circumference (inches)
  • WC is the waist circumference (inches)

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

What is a Thigh to Waist Ratio?

The thigh to waist ratio is a measure of body fat distribution. It is calculated by dividing the circumference of the thigh by the circumference of the waist. This ratio can help indicate whether an individual has a higher risk of cardiovascular diseases and other health issues associated with central obesity. A lower thigh to waist ratio may suggest a healthier body fat distribution.

How to Calculate Thigh to Waist Ratio?

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


  1. First, measure the waist circumference (WC) at the narrowest point, usually just above the belly button.
  2. Next, measure the thigh circumference (TC) at the fullest part of the thigh.
  3. Use the formula TWR = TC / WC to calculate the thigh to waist ratio.
  4. Finally, compare the calculated ratio with the calculator above to verify your result.

Example Problem : 

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

waist circumference (WC) = 32 inches

thigh circumference (TC) = 22 inches
