Why no trash bags between 13 & 30 gallon sizes?

Factual Questions
1

There are several sizes smaller than 13 gallon, and many sizes larger than 30 gallon, but I’ve never seen any sizes in between those. How come? Or if they do exist, who sells them?

There you go. 20 gallon. They also sell 25. You usually see 13 and 30 because most kitchen trash cans are 13 and most larger cans are 30. There are sizes in between though.

Thanks for that. I was hoping to find something at a local store, but it seems that Walmart only offers them online.

I buy Kirkland-brand 18-gallon bags at Costco for my trash compactor.

I also see an 18 gallon trash compactor bag at Home Depot.

I was going to suggest trash compacter bags also. They are very heavy duty and somewhere in that range you need.
