Kitchen Layout Dimensions

Forget the work triangle. Modern kitchen design is about zones and precise clearances.

Clearances That Matter

The National Kitchen and Bath Association (NKBA) recommends a minimum walkway of 36 inches, but 42 inches is required for a single cook, and 48 inches for a multi-cook kitchen. When an island is introduced, the space between the perimeter cabinets and the island is where most designs fail.

Work Aisle (Multiple Cooks)48"54"

The Myth of the Work Triangle

Developed in the 1940s, the work triangle (sink, stove, fridge) assumes a single cook preparing a meal from scratch. Today, kitchens are social spaces with multiple workstations. Focus instead on:

  • Prep Zone: Continuous counter space (minimum 36") next to the sink.
  • Cooking Zone: Clearance around the range, with heat-resistant landing areas.
  • Cleanup Zone: Dishwasher placement ensuring the open door doesn't block traffic (requires 21" standing room).
