Figuring out what size liner bags you need for your outdoor trash can is simpler than it seems! The key is to grab a tape measure and get your can's dimensions. First, measure the circumference around the top of the can. Then, measure the height from the bottom to just below the rim. Finally, note the can's gallon capacity, which is often printed on it.
With these numbers, you can match them to the specifications listed on liner box labels, which typically show the bag's dimensions and gallon capacity. A good rule of thumb is to choose a bag with a gallon size that matches or slightly exceeds your can's capacity. The liner should be tall enough to drape over the rim by a few inches, ensuring a secure fit that won't slip in. For rectangular cans, pay close attention to the length and width. If your can has a unique shape, look for "flex-fit" or "stretchable" bags that can conform better. Taking a few minutes to measure correctly will save you from the hassle of ill-fitting bags, leaks, and messes, making trash day a breeze.
