These black garbage bags are available in regular and extra strength, in sizes to fit different containers and receptacles.
To determine the width of the garbage bags you will need, measure the perimeter (for a rectangular opening) or diameter (for a round opening) of your garbage can and divide by 2.
To determine the height of the garbage bags you will need, measure the height of your garbage can, then add four inches for overhang plus half the width (diameter) to cover the bottom of your can.
