How big is the cabinet

Cabinets come in standard sizes: base cabinets are typically 34. 5 inches high, 24 inches deep, and 9–48 inches wide; wall cabinets are 12 inches deep and 30–42 inches high; tall cabinets range from 84 to 96 inches in height.

Base Cabinets

Base cabinets form the foundation of kitchen storage and support countertops. The standard height of a base cabinet is 34. 5 inches, which becomes approximately 36 inches when a countertop is added, providing an ergonomically optimized counter height.

Depth is usually 24 inches, though corner or Lazy Susan units may extend to 33 inches for better storage access. Widths vary widely in 3-inch increments from 9 inches to 48 inches, allowing flexibility for sinks, appliances, and drawer banks. Small widths (9–18 inches) are ideal for spice racks or narrow storage, medium widths (21–36 inches) fit most sinks and dishwashers, and large widths (39–48 inches) accommodate large drawers or corner units.

Wall Cabinets

Wall cabinets, also called upper cabinets, are typically 12 inches deep, though deeper units (up to 24 inches) are used above appliances like refrigerators. Standard heights are 30, 36, or 42 inches, depending on ceiling height and design preferences. The bottom of wall cabinets is usually installed 15–18 inches above the countertop to allow workspace clearance.

Widths range from 9 to 48 inches in 3-inch increments, with smaller cabinets often having a single door and larger cabinets featuring double doors.

Tall Cabinets

Tall cabinets, also known as pantry or utility cabinets, maximize vertical storage. Standard heights are 84, 90, or 96 inches, with 96-inch units often running floor-to-ceiling in rooms with 8-foot ceilings. Depths are typically 12 inches for pantry storage or 24 inches for utility cabinets that house brooms, vacuums, or built-in appliances.

Widths commonly range from 24 to 36 inches, with 36-inch-wide units recommended when pull-outs or door-mounted storage are included.

Custom and Filler Cabinets

Custom cabinets can be made in 3-inch increments beyond standard sizes, offering flexibility for unique layouts or maximizing storage in tight spaces. Filler cabinets, used to close gaps between walls and cabinets, are typically 3, 6, or 9 inches wide. Understanding these dimensions helps ensure proper fit, accessibility, and storage efficiency while planning kitchen or storage layouts.
