A frame-and-panel door is a good hand-tool project because it does not depend on a large, perfectly flat sheet of wood. The frame carries the structure, while the panel floats inside it so seasonal wood movement does not split the door. The method suits a wardrobe, linen cupboard, or built-in cabinet, and it can be adapted to beginner or intermediate skill levels.
Plan on a full day for one door if you are comfortable cutting joints, or a weekend if this is your first mortise-and-tenon project. The example below is for a door approximately 24 inches wide by 72 inches tall, but the joinery scales to other sizes.

Design and Materials
Use four frame members: two stiles running the full height and two rails between them. A practical finished frame width is 2 1/2 to 3 inches. For a 24-inch-wide door with 3-inch stiles, the rails will be about 18 inches long before allowing for tenons.
For a solid-wood door, use quarter-sawn or reasonably straight-grained boards where possible. Pine is inexpensive and easy to work, but soft knots can crush during chopping. Poplar is a forgiving painted option. Oak, maple, and cherry are harder and more durable, but they demand sharper tools and more careful layout.
| Material | Advantages | Drawbacks | Best use |
|---|---|---|---|
| Pine | Cheap, easy to cut, widely available | Dents easily; knots can distort parts | Painted utility doors |
| Poplar | Stable, machines and chisels cleanly | Usually needs paint; can vary in color | Paint-grade wardrobes |
| Oak or maple | Hard-wearing and attractive under clear finish | More expensive and slower to hand-cut | Visible furniture doors |
Buy boards at least 1 inch thick and prepare them to about 3/4 inch finished thickness. You will also need a panel. A solid panel can be made from several narrow boards, or you can use 1/2-inch plywood for a more stable, painted door. Plywood is the cheaper and safer choice when the wardrobe is in a damp room or when you want to avoid panel glue-up work.
Tools and Setup
At minimum, gather a fine-tooth hand saw, a back saw, a set of sharp chisels, a marking knife, combination square, bevel gauge, clamps, mallet, and a plane. A coping saw is useful for cutting the panel profile, though a rabbeted flat panel needs no profile.
A marking gauge is worth buying if you do not own one. It keeps mortises, tenons, and panel grooves aligned from one part to the next. A cheap plastic square is a poor substitute; even a small error repeated across four joints can leave the door twisted.
Make a flat work surface. A door assembled on a cupped bench can be perfectly joined yet dry out of square. Check your bench with a straightedge before starting.
Prepare and Mark the Parts
Mill the stiles and rails to the same thickness and make their face sides flat. Mark a reference face and edge on every part. Cut the stiles to final length. Cut the rails about 1/16 inch long, then plane them to fit exactly between the stiles.
Mark the inside edges of the frame and lay out the panel groove. A 1/4-inch-wide groove positioned 3/8 inch from the front face is common. Stop the groove before the visible ends of the stiles, or plan to conceal its ends inside the mortises. The panel should be loose enough to move, not wedged tightly in the groove.
For a solid panel, estimate seasonal movement across its grain. A 20-inch-wide panel can move around 1/8 inch or more in a dry-to-humid environment. Leave roughly 1/16 inch of clearance at each side, then center the panel during glue-up. Never glue the panel into the grooves.
Cut the Mortises and Tenons
Use haunched or plain mortise-and-tenon joints. For a 3/4-inch-thick frame, a tenon about 1/4 inch thick and 1 1/2 to 2 inches long is appropriate. Keep at least 1/4 inch of wood outside the mortise to prevent a split stile.
Mark mortises on the inside faces of the stiles. Chop from both ends toward the middle, removing waste in shallow cuts. Keep the chisel walls square and check depth frequently. A mortise that is too deep is usually harmless; one that breaks through the stile is a ruined part.
Transfer the mortise positions to the rails with a marking knife. Saw the tenon shoulders first, then the cheeks. A fine-tooth pull saw can make clean shoulder cuts, but any sharp back saw works. Pare to the lines rather than forcing the saw to be perfect. The tenon should enter with firm hand pressure and seat fully without a mallet.
Test every joint before cutting the panel. If a shoulder has a gap, pare the shoulder carefully. Do not compensate by shortening the tenon; that weakens the joint.
Make the Panel
For a solid raised panel, glue boards with alternating growth-ring direction, then flatten both faces with a plane. Let the panel rest for several days before final sizing. Cut the panel so it fits the grooves with visible side clearance.
A flat plywood panel is simpler. Cut it approximately 1/16 inch smaller than the groove-to-groove opening in both directions. Cover the exposed edge with solid lipping if the door will be viewed from the side. For a painted wardrobe, plywood is often the sensible budget option: it saves time and is less likely to bind.
If making a raised panel by hand, bevel the back edges gradually with a rabbet plane or shoulder plane. Leave a flat tongue about 1/4 inch wide to enter the groove. Work slowly; an overly thin tongue can snap during assembly.
Dry Assemble and Glue
Assemble the frame without glue and measure both diagonals. They should be within 1/16 inch for a wardrobe door. Check that the panel is centered and that the joints close without excessive force.
Apply glue only to the tenon cheeks and inside the mortises, not to the panel or grooves. Use two clamps across the rails and protect the faces with scrap blocks. Measure the diagonals again while the glue is wet. If the door is out of square, push the long diagonal corner inward until both measurements match.
Wipe squeeze-out before it hardens, but avoid flooding the joint with a wet rag. Let the assembly cure for at least 4 hours, preferably overnight. Rushing this stage can pull a joint apart when you plane the door.
Fit, Hang, and Finish
Plane the edges until the door fits its opening with about 1/8 inch clearance at the sides and top. Leave 3/16 to 1/4 inch at the bottom, especially on a carpeted wardrobe. Check for twist by placing the door on a flat surface and rocking opposite corners.
For hanging, three hinges are safer than two on a tall, heavy door. Use a suitable cabinet door hinge sized for the door’s weight. Mark hinge mortises with a knife, chop across the grain first, and pare down to depth. Install the top and bottom hinges about 5 inches from the ends, then center the third hinge.
Sand only after the door is fitted. Break sharp edges with 180-grit paper, apply finish to all faces and especially the panel edges, and allow the finish to dry before installing the latch. The most common failures are an out-of-square frame, glued-in solid panels, and loose tenons. Careful marking and dry assembly prevent all three.
