That's an excellent question! Finding the right liner makes all the difference for keeping your kitchen clean and functional. For a standard "urban" or modern step-can (the kind with a pedal you press with your foot), you'll most commonly need a 13-gallon trash bag.
Here’s a simple way to be sure:
1. Check the Manufacturer's Info: The quickest way is to look at the manual or the label inside or underneath the can. It often states the recommended bag capacity.
2. Measure Your Bin: If you're not sure, grab a tape measure.
* Height: Measure from the very bottom of the *inside* of the can to just below the rim.
* Width/Depth: Measure the inside length and width at the top.
3. Match the Shape: Most urban cans have a rectangular or square opening. Ensure you buy "rectangular" or "standard" fit bags, not the round, drawstring type for office bins.
A 13-gallon bag is the standard for most kitchen step-cans. It's designed to fit snugly, with enough extra material to fold over the rim, which keeps the bag securely in place. If your can seems taller or narrower, you might need a specific "tall kitchen" or "slim" bag variant.
Pro Tip: After placing the bag, pull the edges fully over the entire rim of the can. This creates a cuff that prevents the bag from slipping down when you toss in heavier waste. It also gives you a clean surface to grab when it's time to take the full bag out.
Happy lining! A well-fitted bag makes taking out the trash a much neater experience.
