Europeans say that everything is bigger in the United States. (French and Saunders had a very funny skit about this.) But nowhere, I think, is this truer than in the cereal aisle of the local supermarket, as I noticed while shopping the other day.
Would you like some Fruity Pebbles? You may choose among three sizes: the Large Size box is 15 ounces. The Family Size box is 20 ounces. The Mega Size box is 27.5 ounces. If you want only a small size box, you will have to buy the Large Size, which is the smallest available.
Other cereal manufacturers use the term Giant Size (apparently instead of Mega Size).
I do not know if even more enormous sizes exist. Perhaps there is, in the storeroom, a Colossal Size box that must be winched into your trunk.
Whatever happened to Small, Medium, Large? These words are directly related. But there is no way intuitively to know the relative dimensions of things labelled Mega, Giant, or Family. (How big is a family?)
