Enter the  cardboard box length (in), the  cardboard box width (in), and the  cardboard box height (in) into the Cardboard Box Weight Calculator. The calculator will evaluate the Cardboard Box Weight. 

Cardboard Box Weight Formula

The following formula is used to calculate the Cardboard Box Weight. 

CBW = L*W*H/166


  • CBW is the Cardboard Box Weight (lbs)
  • L is the  cardboard box length (in) 
  • W is the  cardboard box width (in) 
  • H is the  cardboard box height (in) 

To calculate a cardboard box weight, multiply the length, width, and height to get the volume, then divide by 166.

How to Calculate Cardboard Box Weight?

The following two example problems outline the steps and information needed to calculate the Cardboard Box Weight.

Example Problem #1

  1. First, determine the  cardboard box length (in).
    • The  cardboard box length (in) is calculated to be : 10.
  2. Next, determine the  cardboard box width (in).
    • The  cardboard box width (in) is measured to be: 15.
  3. Next, determine the  cardboard box height (in).
    • The  cardboard box height (in) is found to be: 20.
  4. Finally, calculate the Cardboard Box Weight using the formula above: 

CBW = L*W*H/166

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

CBW = 10*15*20/166 = 18.07 (lbs)

Example Problem #2

The variables required for this problem are provided below:

 cardboard box length (in) = 15

 cardboard box width (in) = 15

 cardboard box height (in) = 30

Test your knowledge and check your answer with the calculator.

CBW = L*W*H/166 = (lbs)
