Cabinet width gets all the attention, but cabinet depth is what determines how a kitchen feels to work in and whether your appliances fit. This guide covers the standard depths for base, wall, and tall cabinets — and when to break from standard.

Standard Cabinet Depths at a Glance

Base Cabinet Depth

Standard base cabinets are 24 inches deep (front to wall). With a typical countertop overhang, the finished counter reaches about 25–26 inches. This depth is what makes standard appliances — dishwashers, ranges — sit flush. For details on base sizing, see our standard cabinet sizes chart.

Wall Cabinet Depth

Standard wall cabinets are 12 inches deep — enough for plates and glasses while keeping them clear of your head over the counter. Two exceptions: the cabinet over the refrigerator is usually 24 inches deep to align with the fridge, and some designs use 15-inch or 24-inch wall cabinets for a pantry-like look.

When to Use Non-Standard Depth

• Tight galley kitchens — 15 or 18-inch-deep base cabinets on one wall can open a narrow walkway.
• Deeper counters — some designers spec deeper base runs for extra prep space or to house a farmhouse sink.
• Banquette or desk zones — shallower cabinets keep seating areas comfortable.
