Smaller, from what I've been able to see, MMario. A lot of them seem to be able to fit under the counter. The Smeg fridge was about the size (and shape) of a North American fridge from the 1930 or 40s, you know, those smallish ones with the rounded corners. It was a very cool looking fridge (made in Italy). This one looks a lot like the one Jamie Oliver had, only his was red, if I remember correctly.

Here's the Smeg page with a lot of the models they sell in the UK:
