Working Clearances and the Space Between Cabinets
Almost every complaint about a remodeled kitchen traces back to a distance somebody shortened by four inches. The cabinets are fine. The finish is fine. The dishwasher door lands against the island, or two people cannot pass behind the range. These are clearance failures, and they are decided on paper months before anything is installed.
Aisle width for one cook and for two
A single cook working a galley or a run opposite an island wants 42 inches of clear floor between the opposing cabinet faces. That is measured from finished front to finished front, so counter overhang and door thickness are already in it. At 42 inches one person can stand at an open base cabinet and still turn without contact.
When two people cook together, or one cooks while a second loads the dishwasher, the number rises to 48 inches. Those extra six inches are exactly the width of a person edging past. Below 40 inches a second body cannot get through while a drawer is open, and the kitchen becomes a single occupancy room no matter how large the floor plan.
The hard floor is 36 inches, and it belongs to a passage that carries traffic but no work, such as the leg of an L running to a back door. Many Yakima bungalows have exactly that condition, where 36 inches is honest and 42 is not available without moving a wall.
Appliance doors project further than people expect
A standard dishwasher door drops to horizontal and reaches 24 to 26 inches out from the cabinet face. That is only half the requirement. Somebody has to stand beyond the open door and lean over it to load the lower rack, which needs another 21 inches of body space. Added together, a dishwasher wants 45 to 48 inches of clear floor during use.
A 30 inch range door swings out 22 to 24 inches, but the user is pulling a hot, heavy sheet pan across it, so the working position sits further back. Allow 42 inches minimum and treat 48 as the target where the oven faces an island.
Landing space beside the heat and beside the cold
Every appliance needs a place to put things down. Beside a cooktop, plan 15 inches of uninterrupted counter on one side and 12 on the other. In a peninsula or island, extend that to 15 inches on both sides, because there is no wall to stop a pan handle. A cooktop set within 3 inches of a tall cabinet has no landing at all on that side, and the pan gets set on the burner grate next door.
The refrigerator wants 15 inches of counter on its handle side, or directly across an aisle no wider than 48 inches. A refrigerator at the end of a run with a wall on the handle side is a two trip appliance for the rest of its life.
Corners, where doors and drawers meet
Two runs meeting at 90 degrees create a conflict that is invisible in plan view. A door hinged on the corner side swings across the face of the adjoining cabinet and its knob strikes the neighbor's drawer front. A drawer pulled out in one run blocks the door in the other. The remedy is a filler strip of 2 to 3 inches at the inside corner, which pushes both boxes far enough apart that hardware clears hardware. Where a drawer bank sits on one leg, 3 inches is the safe number, and skipping it is the commonest source of a scarred cabinet face in the first year.
Islands set too close
Clearance mistakes concentrate at the island, because it is the one element that can move a few inches at the drawing stage and never again. Set 42 inches to the perimeter run on any side with no appliances, 48 inches on the side facing a dishwasher, range or refrigerator, and check the seating side separately. A 36 inch high counter with a 15 inch knee overhang wants 24 inches of width per stool and 32 to 36 inches behind the stool for someone to walk past a seated person. An island measured at 42 inches to the cooking run and seating three on the far side usually hides a 30 inch pinch point somewhere, and that pinch point is what the household feels every day.
