What Size Trash Bag Do You Need? Easy Steps to follow.

Choose your can shape

For square/rectangle trash cans: 

Take the perimeter (sum of all the sides) of your trash can and divide by 2. This will be the width of your trash bag.

(Example: Perimeter of can = 32”
Width of trash bag = Perimeter (32) divided by two = 16”)

Go to shop

For round trash cans: 

Take the diameter (width of your trash can) and multiply by 3.14 (pi). Take this number and divide by 2. This will be the width of your trash bag.

(Example: Diameter = 16″
Width of trash bag = 16 x 3.14 = 50”;
50 divided by 2 = 25.)

Determine the height of the trash bag you will need:

Measure the height of your trash can or look up its dimensions online. Add four inches for overhang plus half the width (diameter) to cover the bottom of your can. This will be your trash bag’s height.

Example: Toter 64 Gallon Wheeled Trash Can
Height: 42″
Diameter/Width: 24″
Bag height needed: 42 (can height) + 4 (overhang) + 12 (1/2 can width) = 60.


Note: While your measurements may not match up exactly, simply rounding up or down a few inches should be just fine. 



For every day, kitchen-type trash, a .90 Mil will do just fine.

For heavier trash and items with sharp edges (cardboard boxes, wood, metal, yard waste), choose a 1.5 Mil bag or higher.

For light trash (papers, tissues, etc.), thinner, high density bags will suit your needs.

If you’re even the slightest in doubt whether your measurements are correct, please don’t hesitate to speak with one of our trash bag experts.
