Its a 64 gallon bin but I'm not packing it in either, trash is bagged. I guess I should have figured that based on the reaction in the comments. I'm probably tossing in 2-4 13 gallon tall kitchen bags of trash into there a week and even that much is enough to have it fill up to the top of the lid. I can squeeze in two weeks of trash in there if I forget to put it out for pickup one week but no further.
