Our fridge (in UK) is similar to what Perpetua posted, but when the children lived at home, we found it convenient to have more space, and bought another fridge which is an under-the-counter one with no freezer compartment. I probably keep more things in the fridge than are strictly necessary - bread, carrots, eggs etc, at least in part because it keeps them tidied away. And it's certainly easier to do a 'big shop' once a week rather than replenish the ingredients every day. I think more frequent shopping may be more the custom in continental Europe than here.
American appliances are in general a lot bigger, I think. I remember that on our first family trip to Disney World, we stayed in a cabin on the campsite. The stove was bigger than a regular stove would be here—the standard size here would be 60cm wide, and the one in the cabin was at least 70cm by my reckoning. And I read, in my Unofficial Guide, complaints from some visitors about how small the stove was! The only time I've ever wished for something a little larger than the regulation 60cm oven was when I cooked suckling pig, and had to hack it in half to fit it in. The refrigerator, incidentally, was very generously sized by my standards (and we only used it for milk, and freezing water bottles overnight).
