Most standard espresso machines (semiautomatic and automatic) use a 57 mm or 58 mm coffee tamper. Many people want a coffee tamper that fits snugly into the portafilter, and some prefer a millimeter (or so) of wiggle room, so that they can more easily manipulate the coffee tamper while tamping. But note that the coffee tamper doesn't get pushed down into the bottom of the filter basket (which can be slightly tapered). So it's the inner diameter at the top of the basket that you'll need to measure to size your coffee tamper correctly.
