That's a great question! Finding the right size liner makes cleanup so much easier and prevents messy leaks. Here’s a simple, step-by-step guide to get it right for your specific can.
First, the most reliable method is to check your trash can's manual or the manufacturer's website. Look up your exact model number, usually found on a sticker or embossed on the bottom or inside the rim. The product specs will often list the recommended liner size or capacity.
If you don't have the model info, grab a measuring tape. You'll need two key measurements:
1. Height: Measure from the *bottom interior* of the can up to just below the rim. Add 4-6 inches to this number. The extra length allows you to cuff the liner over the rim for a secure hold.
2. Gallon Capacity: This is the most common size indicator. If your can doesn't have it labeled, calculate it. Measure the interior height and width (for round cans, measure diameter). For rectangular cans: (Length x Width x Height) / 231 = Gallon capacity. For round cans: (3.14 x Radius² x Height) / 231.
Armed with these measurements, match them to liner packaging. Liner boxes list dimensions like "24" x 33"" or a gallon fit like "Fits up to 32-Gallon Cans." Remember, the "fits up to" gallon number should be *equal to or slightly larger* than your can's capacity for a snug fit.
A quick pro tip: If your can has a unique shape or a wide top, look for "drawstring" or "flex-fit" liners designed to expand and conform. When in doubt between two sizes, choose the larger one—you can always tuck the excess, but a too-small bag won't stay put.
With these tips, you'll secure the perfect liner every time, keeping your outdoor space neat and tidy
