Most kegerators will fit 1 full keg, 2 pony or slim quarter kegs, or up to 4 torpedo kegs. If you’re thinking countertop, those will be your mini kegs. Many models now come with removable shelves to store bottles and cans along with your kegs — when used, that functionality does limit the size of keg that can be stored, so that could be a little something to keep in mind.
