This is small enough to fit in the refrigerator door butter keeper, and large enough that the cover doesn't hit the sides and ends of the food item. I like the markings along the edges good for both butter and cream cheese. I use mine strictly for cream cheese, and it is perfect. For my situation it has proved to be a real benefit, since I have a dog that steals food off the table. As long as it is there with the cover on, he doesn't take it. I only remove the cover while I am eating, and put it back on as soon as I have finished and put it back in the fridge. My old container was much smaller, messier, and very easy for him to grab and make off with. So far, this one has remained safe. Its larger size and rounded top edges of the slick cover seem to be a deterrent.
