Enter the shoulder measurement (in) and the waist measurement (in) into the Shoulder to Waist Ratio Calculator. The calculator will evaluate and display the Shoulder to Waist Ratio. 

Shoulder to Waist Ratio Formula

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

SWR = S / W
  • Where SWR is the Shoulder to Waist Ratio ( )
  • S is the shoulder measurement (in) 
  • W is the waist measurement (in) 

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

How to Calculate Shoulder to Waist Ratio?

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

Example Problem #1:

  1. First, determine the shoulder measurement (in). 
    • The shoulder measurement (in) is given as: 38.
  2. Next, determine the waist measurement (in). 
    • The waist measurement (in) is provided as: 30.
  3. Finally, calculate the Shoulder to Waist Ratio using the equation above: 

SWR = S / W

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

SWR = 38 / 30 = 1.266

Example Problem #2: 

For this problem, the variables required are provided below:

shoulder measurement (in) = 40

waist measurement (in) = 32

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