A small cabinet is a good advanced project because it brings several skills together: accurate case joinery, square assembly, and doors that move without rubbing. This plan makes a cabinet about 24 inches wide, 12 inches deep, and 30 inches tall, with two frame-and-panel doors. Adjust the dimensions to suit your space, but keep the case square and build the doors to fit the finished opening—not just the drawing.

Plan the cabinet and choose materials
Use 3/4-inch plywood for the sides, top, bottom, and fixed shelf. A 1/4-inch plywood back fits into a rabbet in the case and helps hold it square. For the door frames, choose straight, dry hardwood such as maple, cherry, or poplar. Poplar is often a sensible paint-grade choice; for a clear finish, choose boards whose color and grain you like. A sheet of cabinet-grade plywood is worth inspecting in person when possible: voids at the edges and a bowed sheet can complicate clean joinery.
Frame-and-panel doors allow the solid-wood frame to expand and contract across its width while the panel floats in grooves. The panel should not be glued into those grooves. You can use a solid-wood panel or a stable plywood panel, depending on the finish and the look you want.
Set dimensions and make a cut list
For the example cabinet, cut two sides at 30 by 12 inches, and a top and bottom at 22 1/2 by 12 inches. Those parts make a 24-inch-wide case when the top and bottom fit between the sides. Cut a fixed shelf to fit between the sides after checking the actual case width. Make the back about 1/4 inch smaller than the case’s rabbeted opening so it can drop in without forcing.
Before cutting, decide whether the top and bottom will sit between the sides or cover their edges. The dimensions above assume they sit between the sides. A 1/4-inch-deep rabbet around the back edges is a practical fit for the back. Add a fixed shelf if the cabinet needs one; locate it from the intended contents rather than splitting the interior automatically.
Door size depends on your hinges and reveal. For a pair of overlay doors, a starting point is two doors about 11 7/8 inches wide each, leaving roughly 1/8 inch between them and small gaps at the outside edges. Verify the required overlay against the hinge instructions, then size the doors after the case is assembled and measured.
Choose joinery and tools
Confirmat screws, pocket screws, or dados can all make a serviceable cabinet. Dados give a clean, strong shelf connection, but require accurate setup. Pocket screws are quicker and easier to adjust, though exposed locations need plugs or a different joint. For this project, dados for the shelf and screws or glue-and-screw joints for the case are reasonable choices. A router table and rail-and-stile bit set can speed up door work, but a table saw with a groove blade and careful tenon setup can do the job too.
Compare the main door-panel options before cutting:
| Panel choice | Advantages | Trade-offs |
|---|---|---|
| Solid wood | Traditional appearance; can be matched to the frame | Must be sized to float in the grooves; seasonal movement can cause cracks if glued |
| 1/4-inch plywood | Stable, straightforward, and usually cheaper | Exposed edges need a detail or cover; veneer may not match solid framing |
For a painted cabinet, plywood is usually fine. For a clear finish, solid wood gives a consistent material, but it takes more care to keep the panel free to move. A set of 24-inch bar clamps is useful for assembling the case and doors; inexpensive clamps are adequate if they hold pressure evenly and do not bow the work.
Cut and assemble the case
Break down the plywood with a track saw, circular saw and guide, or table saw. Cut matching parts as a pair where possible, and check each cut against a square. A chipped face veneer is hard to disguise, so use a sharp blade and support the sheet fully. Cut the back rabbet before assembly, and cut shelf dados if you are using them. Test each joint on offcuts before committing to the case parts.
Dry-fit the case and measure both diagonals. They should match within about 1/16 inch; if they do not, adjust the clamps before the glue sets. Check that the sides are square to the top and bottom, then install the back. A back fitted into its rabbet is more than a cover: it resists racking. If it is forced into a case that is out of square, it will lock in that error.
Make frame-and-panel doors
Rip the rails and stiles from straight stock, leaving them slightly oversize until you have checked the case opening. A practical frame uses stiles about 2 inches wide and rails about 2 inches wide, though narrower parts suit a smaller cabinet. Cut a groove about 1/4 inch wide and 3/8 inch deep along the inside edges. Make matching tenons on the rail ends, or use a rail-and-stile cutter set. Test the fit on scraps: joints should seat fully without needing excessive clamp pressure.
Measure the panel opening and add enough width and height for its edges to sit in the grooves—often about 1/2 inch total in each direction for 1/4-inch-deep grooves. Leave about 1/16 inch of clearance at the panel’s edges so it can move. Do not glue the panel into the frame. A dab of flexible space balls or small foam spacers can keep a loose panel from rattling without restraining it.
Dry-assemble each door on a flat surface and check its diagonals. Glue the rail-and-stile joints, clamp gently, and check for twist before the glue cures. Too much pressure can bow the frame or squeeze the joints out of alignment. Sand the doors before hanging; it is much easier to reach the inside edges at this stage.
Hang, adjust, and finish
Install the hinges according to their instructions. Concealed cup hinges are adjustable and convenient, but require accurate cup drilling; butt hinges are simpler but offer less adjustment. Use a drilling jig for concealed hinges if you do not have a drill press. Make a test hole in scrap of the same thickness first—drilling too deep can break through the door face.
Set the doors with even gaps, commonly about 1/8 inch, then adjust the hinges so they do not rub at the top, bottom, or center. If a door binds, check the case for square before trimming the door. Sand to 180 grit, ease sharp edges, and apply a finish suited to the cabinet’s use. Finish both sides of solid-wood panels similarly to reduce uneven moisture exchange. Let the finish cure before installing pulls or loading the cabinet; a dry-to-touch surface can still mark under hardware.
