A wedge-shaped wooden doorstop is a forgiving first project: it needs only a few cuts, works with inexpensive lumber, and gives you a useful chance to practice measuring, sanding, and finishing. The key is to make the wedge long enough to slide under the door and shallow enough to hold it without forcing the door upward.

Plan the shape and dimensions
For a typical interior door, start with a blank about 6 inches long, 2 inches wide, and 1 inch thick. Cut one long face at an angle so the finished wedge tapers from roughly 1 inch thick at the back to about 1/8 inch at the tip. These are starting dimensions, not fixed rules: a heavy door or a larger floor gap may call for a thicker blank or a steeper wedge.
Measure the gap under your door before cutting. If it is less than 1/4 inch, a thick, blunt tip may not fit. If the door is heavy, a very shallow wedge may slide out instead of holding. Leave a little extra length for trimming; you can remove wood, but you cannot add it back.
Materials and tools
Use a straight, dry piece of hardwood or a sound offcut. Maple, oak, and beech are durable choices, but a scrap of pine is fine for a light interior door. Avoid wood with cracks, loose knots, or a cup across its width; those flaws can make the thin tip split or the wedge rock on the floor.
You will need a pencil, ruler or tape measure, square, hand saw, clamps, and sandpaper in about 80-, 120-, and 180-grit. A hand plane can smooth the sloped face, but careful sanding is enough. A small woodworking hand saw is a practical choice if you do not already have a suitable saw. For rough shaping, a rasp is optional; it is not necessary for a single simple wedge.
Choose the cutting method that matches what you own and can control safely:
| Method | Good fit | Trade-off |
|---|---|---|
| Hand saw with a marked guide | One doorstop and a basic tool kit | Slower; needs steady sawing to keep the face straight |
| Table saw with a taper jig | Repeat pieces and confident saw users | Fast and consistent, but requires a stable jig and careful setup |
| Jigsaw | Rough shaping when the cut will be sanded | Easy to start, but the sloped face may need more cleanup |
Mark the wedge
On one long side of the blank, mark the thick end at 1 inch and the tip at 1/8 inch. Draw a straight line between the marks. Repeat the marks on the opposite side so the slope runs evenly across the block, rather than twisting from one side to the other. If your blank is not exactly 1 inch thick, use the actual thickness at the back and leave around 1/8 inch at the tip.
For a hand-sawn cut, clamp the blank firmly to a bench with the waste side clear. A helper line drawn on the end grain can make it easier to keep the saw on track. If using a table saw, do not hold a loose wedge by hand against the blade; use a properly secured taper jig and follow the saw’s instructions.
Cut and shape
Saw just outside the line, leaving a little material for smoothing. Keep the blade moving steadily and avoid twisting it to correct the cut midway; that can produce a hollow face. If the cut wanders, do not try to fix a deep dip by sanding the entire piece thinner. Flatten the slope gradually with a plane, rasp, or sanding block instead.
Round the corners and break the sharp edges with 120-grit paper. Keep the broad faces flat so the stop sits steadily on the floor. Sand the wedge face with a long, rigid block, moving along the slope and checking it against a straightedge. Finish with 180-grit. The tip is the weak point: if it becomes feather-thin, trim it back slightly rather than leaving a fragile sliver that may snap.
Test the fit and grip
Slide the wedge under the door from the side, not by forcing it straight down. It should enter with light pressure and stop the door without lifting it noticeably. If it slips, first check that the floor and wedge bottom are clean and dry. Then try a slightly steeper wedge or add a thin strip of rubber to the underside. If it is too thick to enter, reduce the tip carefully or make a new piece with a shallower slope.
Wood alone can be slippery on tile, sealed concrete, and some finished floors. A small piece of non-slip rubber or cork can improve grip, but thick padding may change the wedge angle or keep the tip from sliding under the door. A self-adhesive rubber sheet can be cut to fit the underside; test a small piece first to ensure its adhesive does not mark the floor.
Finish and maintain
For a utility doorstop, a smooth sanded surface is often enough. If you want a finish, apply a thin coat of water-based polyurethane or a small amount of oil, following the label directions. Keep finish off any rubber pad and allow the piece to cure fully before use; uncured coatings can transfer to a floor. On a pine stop, expect dents and wear over time. Re-sand the tip or replace the wedge if it cracks, becomes too smooth to grip, or no longer holds the door reliably.
Store the stop where it will not be stepped on. Its pointed end is useful under a door but can still splinter if dropped or crushed, so round the tip slightly and inspect it occasionally. For a single lightweight interior door, an inexpensive scrap and hand tools are usually enough; spend more on tools only if you plan to make several stops or other projects that use them.
