Those with larger families or who entertain often may want to go as wide as 54 inches for work aisles. This will allow two people to easily pass behind someone working at the countertop, sink or appliance.
Also, try to keep appliances away from any corners, as corners prevent full access to the appliance, and the adjacent cabinets cannot be opened if the appliance door is also open.
This applies to your cabinets as well — make sure you can open all of your cabinet doors and drawers without their running into one another. It's tough to avoid this with corner cabinets, but all other cabinets should open freely without banging into another door or a drawer.
