Figuring out the right size liner bag for your outdoor trash can is simpler than you might think. The key is to focus on two main measurements: the dimensions of your can and the listed dimensions of the bags.
First, grab a measuring tape. For the height, measure from the very bottom inside the can to the top rim. For the width or diameter, measure across the top opening. If your can is rectangular, measure the length and width. If it's round, measure the diameter. Jot these numbers down.
Now, look at any box of trash bags. You'll see dimensions like "30" x 33"" or "45" x 48"". The first number is typically the width (the opening of the bag when laid flat), and the second is the length (or height when in use). For a perfect fit, your bag's width should be slightly *larger* than your can's top width/diameter. The bag's length should be *greater* than your can's height to allow for folding over the rim.
A great tip is to add 8-10 inches to your can's height for the "overhang" you need to secure the bag. For example, if your can is 40 inches tall, look for bags at least 48-50 inches in length. For gusseted or drawstring bags, ensure the "gusset width" or "expanded width" matches or exceeds your can's top measurement.
Remember, a bag that's too small will slip inside or tear easily, while one that's too large is wasteful and can look messy. Taking two minutes to measure ensures a snug, secure fit that makes cleanup a breeze and keeps your outdoor space tidy.
