The Kitchen Work Triangle

The work triangle is a time-tested principle that connects your three main work areas: the sink, stove, and refrigerator. A well-planned triangle makes cooking more efficient and reduces unnecessary steps.

Work Triangle Rules

  • Total perimeter: 13-26 feet
    Too small feels cramped, too large wastes steps
  • Each leg: 4-9 feet
    No single leg should be too short or too long
  • No obstructions through the triangle
    Islands, tables, or traffic paths should not intersect
  • Landing space at each point
    At least 15" of counter space on each side of the stove and sink
Pro Tip: Work Zones
Modern kitchens often use a "work zone" approach instead of a strict triangle. Create zones for prep, cooking, cleaning, and storage. This works especially well in larger kitchens or those with multiple cooks.

Common Kitchen Planning Mistakes

Avoid these frequent errors that can make your kitchen less functional and more expensive to fix later.

Not enough counter space
Plan for at least 158 inches of usable counter space. Include landing zones next to appliances.
Forgetting about clearances
Allow 42-48 inches between facing cabinets, 36 inches for walkways, and check that all doors and drawers can open fully.
Poor lighting
Plan task lighting under wall cabinets, ambient lighting overhead, and consider natural light from windows.
Ignoring the trash location
Place trash and recycling near the sink or at the end of a prep counter. Consider a pull-out cabinet.
Insufficient electrical outlets
Plan outlets every 4 feet along the counter. Include dedicated circuits for major appliances.
Not measuring appliances
Measure your actual appliances before finalizing cabinet sizes. Standard sizes vary by manufacturer.
