Figuring out the right size liner bag for your specific urban trash can is simpler than you might think. Here are three easy methods to ensure a perfect fit every time.
First, the most reliable method is to measure your trash can yourself. Grab a tape measure. You'll need the height (from the inside bottom to the very top rim) and the width (the diameter for round cans or the length and width for rectangular ones). For the bag height, add 4-6 inches to your can's height to allow for folding over the rim. For the bag width/circumference, it should be slightly smaller than your can's so it fits snugly without sagging too much.
Second, check your trash can for a model number. Many modern bins, especially from popular brands like Simplehuman, have the recommended liner size printed on the bottom or inside the lid. A quick online search of that model number will give you the exact bag dimensions you need.
Finally, know the common standard sizes. Most kitchen cans are between 7-13 gallons. An 8-gallon bag typically fits a tall, slim kitchen bin, while a 13-gallon bag is the standard for many mid-size cans. For larger utility or outdoor urban bins, you might need 30-gallon bags or bigger. When in doubt, buying a small pack of a suspected size to test is a good idea before committing to a bulk purchase.
By measuring your bin, checking for manufacturer details, or using standard size guidelines, you can buy liner bags with confidence, eliminating messy overhang or bags that slip down inside the can.
