How wide do kitchen walkways need to be?
As a comfort guideline: about 42 inches (105 cm) between a counter and the wall or island opposite for one cook, 48 inches (120 cm) where two cooks pass or appliances face each other. The real test is an open dishwasher door with someone walking past; that is the scenario the numbers exist for.
The widths that work
- 42 in (105 cm): one cook, counter to opposite counter, island or wall.
- 48 in (120 cm): two cooks, or appliances opening toward each other.
- Watch the door arcs: dishwasher, oven and fridge doors all claim their strip when open.
See your tight spots before the cabinets arrive
The free kitchen planner uses the 42-inch guideline and marks tighter spots without forbidding them, measures the work triangle at the same time, and shows what an island really requires: island plumbing costs.
Frequently asked questions
Is 36 inches ever enough?
For a pass-through nobody cooks in, it can be. Between working counters it means waiting for each other and bruised hips; the guideline exists because an open oven or dishwasher door instantly eats two feet of any walkway.
Do walkway widths appear in building codes?
Mostly not: kitchen walkways are guideline territory (NKBA-style), unlike bathroom clearances which have hard IRC minimums. Legal is easy here; pleasant is the actual bar, and that is what the planner marks.
How does an island change the math?
An island turns one wide room into two walkways, and both need their width. That is the most common island mistake: the room fits the island, but not the island plus two real aisles. Drag it in the planner and the tight side lights up immediately.
