How to Choose the Right Size
- Household size: Larger families or shared offices fill bins faster — aim for 13+ gallons.
- Bag availability: Standard kitchen bags fit 13-gallon cans; commercial liners fit larger sizes.
- Space constraints: Slim and oval cans save floor space in tight kitchens or hallways.
- Usage frequency: The more frequently it’s emptied, the smaller you can go without odor issues.
