What you need to consider when creating a butler’s pantry? Ideally, according to Kitchen Wise a butler’s pantry should be at least 1600mm wide and 2200m deep. This space allows for a 600mm-deep workbench that would fit a fridge, oven, microwave, sink and customised food storage space. If you have 2400mm by 3000mm of space available, your work area will be about the size of a small kitchen.
