Candy Buffet - What size bags for guests?

Unless you are pre-filling them I don't think the size is going to make much of a difference. I am getting those bags and I am getting the 3.5 because we are putting little cookies 2 or 3 per bag, and don't want them to see super empty. If you are pre-filling them then I would get the smaller size.

We are not pre-filling them. I guess I’m just trying to figure out how to make sure the guests don’t feel like we’re giving them a bag to put three M&Ms in, but also making sure that one guest doesn’t over stuff, I’m probably overthinking this way too much. I think we have an excess of 40 pounds of candy so it shouldn’t be a problem either way as I think we have estimated nearly 3/4 lb per person...

My bags were 5x7. I would choose the bigger size especially depending on the types of candy you have.

If you aren't pre-filling them, then I would get a smaller size, people tend to fill up whatever container size they get, and you want everybody to get some...

Perhaps something like this from Etsy ?

Seems like the ones you are looking at are quite large on the bottom, which would allow for a lot more to be put in each one. I do like that that you can close those, though. I would hate to run out of candy!
