A simple wooden picture frame is a useful first project: it takes little stock, introduces accurate measuring and cutting, and can be made with basic tools. The key is not fancy joinery. It is cutting the four pieces to matching lengths, keeping the corners square, and leaving enough room for the glass and artwork.

Choose a design that fits your tools
This plan makes a frame for an 8-by-10-inch picture. It uses four straight boards, butt joints, and a rabbet—a shallow ledge cut around the back—to hold the glazing, picture, and backing. If you do not have a router or table saw, a shop can cut the rabbet for you, or you can use ready-made frame moulding with a groove already cut.
| Approach | What you need | Best for | Trade-off |
|---|---|---|---|
| Square-cut butt joints | Saw, square, glue, clamps | A first frame with simple tools | Joint ends remain visible; reinforcement helps |
| 45-degree miters | Miter saw or accurate miter box | A traditional frame look | Small angle errors make corners gap |
| Ready-made grooved moulding | Cutting tool and corner clamps | Fast assembly without routing | Less choice in profile and wood |
For the simplest build, use 1-by-2-inch boards, which are about ¾ inch thick by 1½ inches wide. A straight-grained softwood board is inexpensive and easy to cut; hardwood costs more but dents less and can take a cleaner finish. Avoid boards that are twisted, cupped, or badly bowed. A frame amplifies small defects.
Materials and tools
Gather one board at least 36 inches long, wood glue, four small corner brackets or corrugated fasteners, sandpaper in 120- and 180-grit, and a finish. For the frame insert, use glass or acrylic, a picture, and a thin backing panel. Glass is usually cheaper and resists scratches, but it can break. Acrylic is lighter and safer around children, though it scratches easily and should be cleaned with a soft cloth.
You will also need a tape measure, pencil, square, saw, and clamps. A set of small bar clamps is convenient, but inexpensive corner clamps or a homemade clamping jig can work. If cutting the rabbet yourself, use a router with a rabbeting bit or a table saw with a suitable setup and guard. A rabbeting bit is useful, not essential if a lumberyard can do the cut.
Measure the opening and cut list
Do not assume the picture measures exactly 8 by 10 inches. Measure the artwork or backing you will actually use. For this example, make the rabbet opening 8⅛ by 10⅛ inches, giving the picture about ⅛ inch of clearance in each direction. The glass, picture, and backing should fit without bending or forcing them.
Cut the frame’s outside pieces to these lengths, measured long point to long point at the corners:
- Two rails: 11⅝ inches
- Two stiles: 9⅝ inches
Those lengths assume 1½-inch-wide stock and a ⅛-inch rabbet lip on each side. Check the arithmetic against your actual board width and rabbet before cutting: outside length equals opening length plus twice the board width, while the opening is smaller than the outside by twice the rabbet lip. Cut one piece, test it against the planned opening, then cut its matching partner. A stop block helps keep paired pieces equal.
Cut and assemble the frame
Mark the rabbet on the back face, ⅛ inch in from each inner edge. Cut it about ¼ inch deep, enough to hold the insert stack. Make several shallow passes rather than trying to remove all the material at once. Keep hands clear of the blade or bit, and follow the tool’s guard and safety instructions. If you are new to routing, practise on scrap first; a slipping bit can chew up the visible edge.
Dry-fit the pieces on a flat surface. Check the opening with a square and compare the two diagonals. If the diagonals differ, the frame is out of square. Correct the cuts before gluing; clamps can pull a slightly loose joint together, but they will not fix pieces cut to the wrong length.
Apply a thin layer of glue to the butt joints, align the faces, and clamp the frame. Measure diagonals again before the glue sets. Add small brackets or corrugated fasteners across the back of each corner for extra strength. Wipe away squeeze-out with a damp cloth, then let the glue cure according to its label. Too much glue can leave a visible stain under finish.
Sand, finish, and fit the picture
Sand the frame faces and edges with 120-grit, then 180-grit paper. Ease sharp edges with a few light passes. Do not round the inside edge heavily; that can expose uneven cuts around the opening. Apply a thin coat of paint, clear finish, or oil that is suitable for the wood. Test it on an offcut first, especially with pine, which can absorb stain unevenly.
Once the finish is fully dry, place the glazing, picture, and backing into the rabbet. Secure the stack with small brads, flexible tabs, or turn buttons, leaving enough pressure to hold it without bowing the backing. If using glass, handle it by the edges and avoid overtightening fasteners. Add a sawtooth hanger for a light frame; use a wire or sturdier hanging hardware for a heavier one. Weigh the finished frame and choose hardware rated comfortably above that weight.
Common mistakes to avoid
The most common problem is a loose or crooked fit. Measure the actual insert stack, allow roughly ⅛ inch of clearance, and test the opening before finishing. A rabbet cut too shallow may not hold all the layers; one cut too deep leaves a weak lip. On a butt-jointed frame, unsupported corners can open if the frame is dropped, so use reinforcement and handle it by the sides rather than one corner.
Keep the first version plain. Accurate cuts and a flat, square assembly matter more than decorative moulding. Once this frame fits cleanly, the same measurements and workflow can be adapted to different picture sizes, wider stock, or mitered corners.
