Building a Cabinet: Complete Guide to Cabinet Construction 2026

Cabinet Construction Methods

There are two fundamental approaches to cabinet building: Face frame cabinets: a solid wood frame (typically 3/4-inch hardwood) is built separately and glued to the front of the plywood box.

Face frames are the North American standard for kitchen and bathroom cabinets.

The face frame covers the plywood box edges and provides a finished appearance.

Frameless cabinets (European style): no face frame -- the cabinet is a simple plywood or MDF box, finished with edge banding on exposed edges.

Doors and drawers mount directly to the box using concealed hinges.

Materials

3/4-inch cabinet-grade plywood is the correct material -- birch or maple ply for painted finish, oak or walnut for clear finish MDF is acceptable for painted cabinets -- very flat, paints beautifully, but heavy and not moisture resistant Particleboard is not recommended for carcass material -- poor fastener holding and moisture sensitivity Face frame (face frame cabinets): 3/4-inch solid hardwood -- poplar for painted cabinets (cheaper, paints well), oak or maple for clear finish

Base Cabinet Dimensions (Standard)

Standard base cabinet dimensions in the US kitchen: Height: 34.5 inches (without countertop).

With a 1.5-inch countertop, the finished height is 36 inches.

Depth: 24 inches (including face frame and door front) Width: varies by design -- standard widths are 12, 15, 18, 21, 24, 27, 30, 33, and 36 inches

Wall Cabinet Dimensions

Height: 12, 15, 18, 24, 30, or 42 inches depending on application Depth: 12 inches standard; 15 inches for some larger wall cabinets Width: same widths as base cabinets

Box Construction: Cutting the Parts

For a simple frameless base cabinet: Parts list for a 24x24x34.5-inch base cabinet: 2 sides: 23.25 x 34.5 inches (3/4 plywood) 1 top: 22.5 x 23.25 inches (3/4 plywood) 1 bottom: 22.5 x 23.25 inches (3/4 plywood)

Joinery Options for Cabinet Boxes

Pocket screws (Kreg system): the fastest method.

Drill angled pocket holes in the mating parts and drive screws to pull them together.

Correct for frameless cabinet construction w here the joints are hidden.

The most common method for production cabinet making.

Dado joints: cut a groove (dado) in the sides to receive the top and bottom.

Face Frame Construction

Stiles: vertical members (the sides of the frame) Rails: horizontal members (the top and bottom, and any intermediate rails) Outer stiles are typically 1.5 inches wide Rails are typically 1.5 inches wide for top and bottom, 2 inches for the bottom rail above the toe kick Inner stiles at cabinet divisions are typically 1 inch wide

Installing the Toe Kick

The toe kick is the recessed area at the bottom front of base cabinets: Standard toe kick height: 4 to 4.5 inches Standard toe kick depth: 3 to 3.5 inches The toe kick allows the user to stand close to the counter without stubbing toes on the cabinet front.

A cabinet without a toe kick is uncomfortable to work at for extended periods.

Shelf Pin Holes

Adjustable shelves require a series of shelf p in holes on 32mm centers.

The 32mm spacing is the industry standard that allows fine shelf adjustment.

Methods for drilling shelf p in holes: Shelf p in drilling jig (most accurate) Template with a pattern of holes (fast and repeatable) A fence and a stop collar on the drill bit (adequate)

Installing Cabinet Hardware

Hinges: European (concealed) hinges are the modern standard for cabinet doors.

They adjust in three axes (up-down, in-out, left-right) and are the easiest hinges to install and adjust.

Drawer slides: full-extension soft-close drawer slides are the current standard.

The Blum Tandem Plus Blumotion is the professional standard.

Install the slides level and parallel -- uneven slides cause drawers to rack and bind.

Installing Cabinets

Base cabinet installation sequence: Find the high point on the floor -- base cabinets start from the highest floor point Set the first cabinet at the corner plumb and level Set subsequent cabinets plumb and level with shims Screw adjacent cabinets together through the stiles (face frame) or sides (frameless)

Common Mistakes in Cabinet Building

Not squaring the box: an out-of-square box means doors and drawers will not fit correctly.

Check diagonal measurements before the glue sets.

Skipping the pocket hole clamp: pocket screws pull parts out of position as they drive.

Always clamp the joint before driving pocket screws.

Inconsistent shelf p in hole height: even 1/16-inch variation in hole height makes shelves uneven.
