2 quarts is dessert size at my house. I think my medium-round is around 5 and my medium-oval 7. The big oval is 9.

But that's because crocking is one of my main cooking methods. We started with one that was just barely big enough to fit a chicken, and when it wore out, couldn't find that exact size again so moved up. When I started doing the spaghetti sauce, we got a larger one, and as I did more stuff to freeze, I kinda turned into a size queen because it's less work to make a big batch than two smaller batches.
