The fit is just right. I have an 8 gallon plastic trash container. I was having a very hard time to find a bag that fit and not way too big as 13 gallon bags are. I found a different brand and it kinda fit but was not what I needed. I found this brand at a discount store. I purchased and it was the perfect bag for my trash. They are strong, close with ease, and easy to put in container. I highly recommend them.
