That's a great question! Finding the right size liner makes all the difference—no more messy overhang or bags that slip down inside the can. Don't worry, it's much easier than it seems. You just need two simple measurements and about 30 seconds of your time.
First, grab a flexible measuring tape. If you don't have one, a piece of string and a ruler will work perfectly.
Here’s what to do:
1. Measure the Height: Start from the very bottom inside your empty trash can and measure straight up to the very top rim. Now, subtract about 2-3 inches (5-7.5 cm). This is the ideal *height* for your liner. It allows you to fold the excess over the rim neatly without having too much extra material flopping around.
2. Measure the Width/Girth: For this, you want the circumference. Wrap your measuring tape around the widest part of the *inside* of the can. If your can is rectangular, measure the length and width of the bottom and use the formula: (Length + Width) x 2. This gives you the total distance around.
Now you have your numbers! When you shop for liners, look for packages that list the dimensions. They are often shown as something like "24" x 33"" (width x height). Your "width/girth" measurement should be slightly *smaller* than the bag's listed width for a snug fit. Your adjusted height measurement should match closely to the bag's listed height.
A quick pro tip: If you know your trash can's brand and model, a fast online search for "[Brand Name] [Model] compatible liners" can give you the exact answer. But measuring yourself is the most reliable method for any can, especially generic or older ones. Happy fitting
