Enter the waist circumference (in) and the thigh measurement (in) into the Waist to Thigh Ratio Calculator. The calculator will evaluate and display the Waist to Thigh Ratio. 

Waist to Thigh Ratio Formula

The following formula is used to calculate the Waist to Thigh Ratio. 

WTR = W / T
  • Where WTR  is the Waist to Thigh Ratio
  • w is the waist circumference (in) 
  • T is the thigh measurement (in) 

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

How to Calculate Waist to Thigh Ratio?

The following example problems outline how to calculate Waist to Thigh Ratio.

Example Problem #1:

  1. First, determine the waist circumference (in).
    • The waist circumference (in) is given as: 32.
  2. Next, determine the thigh measurement (in).
    • The thigh measurement (in) is provided as: 13.
  3. Finally, calculate the Waist to Thigh Ratio using the equation above: 

WTR = W / T

The values given above are inserted into the equation below and the solution is calculated:

WTR = 32 / 13 = 2.461

Example Problem #2: 

For this problem, the variables required are provided below:

waist circumference (in) = 45

thigh measurement (in) = 20

Test your knowledge using the equation and check your answer with the calculator above.

WTR = W / T = ?
