Enter the dimensions of your garbage bin to determine the appropriate size for your garbage bag.

Garbage Bag Size Calculation Formula

The following formula is used to calculate the size of the garbage bag needed based on your bin’s dimensions.

Bag Size (Gallons) = (Length * Width * Height) / 231

Variables:

  • Length is the length of the bin (inches)
  • Width is the width of the bin (inches)
  • Height is the height of the bin (inches)
  • Diameter is the diameter of a circular bin (inches)
  • Bag Size is the capacity of the garbage bag (gallons)

To calculate the garbage bag size, measure the length, width, and height of your bin, and use the formula provided. For circular bins, use the diameter and height.

What is Garbage Bag Size Calculation?

Garbage bag size calculation refers to the process of determining the appropriate size of a garbage bag based on the dimensions of your garbage bin. This involves understanding the volume of your bin and ensuring that the garbage bag you use can accommodate this volume without tearing or overflowing.

How to Calculate Garbage Bag Size?

The following steps outline how to calculate the garbage bag size using the given formula.


  1. First, measure the length, width, and height of your bin (for rectangular or square bins) or the diameter and height (for circular bins).
  2. Next, use the appropriate formula to calculate the volume in gallons.
  3. Use the formula from above: Bag Size (Gallons) = (Length * Width * Height) / 231 or Bag Size (Gallons) = (π * (Diameter / 2)^2 * Height) / 231.
  4. Finally, calculate the garbage bag size by plugging in the values.
