Hey there! That's a great question, as using the right liner bag makes cleanup so much easier. For a standard-sized outdoor trash can, which is typically around 32 to 44 gallons, you'll want to look for standard tall kitchen bags or dedicated outdoor trash bags in a corresponding size.
The key is to check the gallon capacity on the box of liners you're buying. A bag labeled for 30-33 gallons is usually a perfect fit for a standard 32-gallon can. You want a bag that's tall enough to fit over the rim of the can with some extra material to fold over the edges—this prevents it from falling in. Bags that are slightly too small will constantly slip inside, and bags that are excessively large are just wasteful and difficult to manage.
Look for liners that are durable and often labeled as "leak-proof" or "high-density." These are thicker and less likely to tear from sharp debris or heavy loads. Drawstring liners are fantastic for outdoor cans because they make tying and carrying the full bag a breeze, helping to contain odors and messes. So, next time you're shopping, just match the gallon size and opt for strength and convenience. Happy cleaning
