Enter the waist circumference (in) into the Waist Belt Length Calculator. The calculator will evaluate the Waist Belt Length. 

Waist Belt Length Formula

The following two example problems outline the steps and information needed to calculate the Waist Belt Length.

WBL = W + 2
  • Where WBL is the Waist Belt Length (in)
  • W is the waist circumference (in) 

To calculate the waist belt length, add 2 inches to the waist circumference.

How to Calculate Waist Belt Length?

The following example problems outline how to calculate Waist Belt Length.

Example Problem #1:

  1. First, determine the waist circumference (in).
    • The waist circumference (in) is given as: 32.
  2. Finally, calculate the Waist Belt Length using the equation above: 

WBL = W + 2

The values provided above are inserted into the equation below and computed.

WBL = 32 + 2 = 34 (in)

Example Problem #2: 

For this problem, the variables required are provided below:

waist circumference (in) = 34

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

WBL = W + 2 = ?
