How to Select the Correct Trash Bag Size

Measuring for Correct Trash Bag Size


  • Bag Width:  Use one-half of the outer circumference of the container.
  • Bag Length:
    • Round Containers:  Use the height of the container, plus one-half of the diameter of the container, plus 3-6 inches, (for overhang or tie).
    • Square or Rectangular Containers:  Use the height of the container, plus the longer diagonal of the bottom of the container, plus 3-6 inches, (for overhang or tie).
  • We only use the Manufacturer "Top Number" for gallon rating.  In other words we show a 55 to 60 gallon Trash bag as 60 Gal (you can always put less in :-)
  • One of the most Environmentally Preferred decisions you can make in trash bag selection is choosing from what is in stock in our warehouse.  We stock the most popular sizes.  Once you determine the Width and Length you need, select the matching size, or the next size up.
  • Pro-Tip:  Reduce trash bag usage and labor by tying them around top of trash can.  It takes 1 minute to remove and replace a trash bag.  It takes 30 seconds to simply empty a trash can with a trash bag secured inside.  In a facility with 100 trash cans, that's a reduction of 100 trash bags and 50 minutes of labor.  $35 per day saved!
