Cabinet depth is simply the measurement from the cabinet’s front edge to the back panel — the part that sits against the wall.
It determines how far the cabinet extends into the room and directly affects storage capacity, countertop width, and accessibility.

For example, a cabinet that’s 24 inches deep extends two feet from the wall — deep enough to hold cookware, dishes, or pantry items without wasting space.

When designed correctly, cabinet depth creates balance: it complements countertop overhang, matches appliances, and allows enough room to move freely around the kitchen.

The standard depth of kitchen cabinets typically defines how far the cabinet extends from the wall. Knowing the standard depth of kitchen cabinets ensures your design remains functional and balanced.
