Cardboard Box Weight Calculator


The Cardboard Box Weight Calculator is a handy tool for determining the estimated weight of a cardboard box based on its dimensions. Whether you’re shipping packages, organizing storage, or simply curious about the weight of a cardboard box, this calculator will provide you with a quick and convenient solution.


The calculator estimates the weight of the cardboard box using a simple formula based on its dimensions. Here’s how it works:

  1. Calculate the volume of the cardboard box:
    • Volume = Length × Width × Height
  2. Estimate the weight of the cardboard box:
    • Weight = Volume × Density

The assumed density used in the calculation is typically 0.1 lbs per cubic inch, which is a common value for cardboard.

How to Use

Using the Cardboard Box Weight Calculator is easy and straightforward:

  1. Enter the length of the cardboard box in inches.
  2. Enter the width of the cardboard box in inches.
  3. Enter the height of the cardboard box in inches.
  4. Click the Calculate button.

The calculator will then provide you with an estimated weight for the cardboard box based on the given dimensions.


Let’s consider an example where you have a cardboard box with the following dimensions:

  • Length: 12 inches
  • Width: 8 inches
  • Height: 6 inches

Upon clicking the Calculate button, the calculator will estimate the weight of the cardboard box as follows:

  • The estimated weight of the cardboard box is 5.76 lbs.

This means that the cardboard box weighs approximately 5.76 pounds.
