Depends on you're using the definition of machine gun as an often crew served weapons designed to deliver suppressive fire, or the BATFE definition, in which all full auto weapons are designated as machine guns.
The Czechs in the runup the Second World War had a 9mm submachinegun with a bipod for use in the suppressive fire role. That would probably have been the smallest under the first definition. By the BATFE legal definition (where any full auto is considered a machine gun), the smallest semi auto handguns, if they underwent a conversion, could take this distinction.
Actually, pretty large. The standard machine guns were 8mm Mauser, .303 Enfield, and 30-06. Larger machine guns such as the .50 Browning were also used. To give you an idea of size, a section of a regular pencil about 1 inch long is the size of the small machine gun bullet.
