Every home ends up with a hole in the drywall eventually — a doorknob dent, a picture hook gone wrong, or something bigger from moving furniture. The good news is that DIY drywall repair is one of the most beginner-friendly home fixes there is. With the right approach for the size of the hole, you can get a wall looking factory-smooth in an afternoon, no contractor required.
What You'll Need
For Small Holes (Under 1 Inch)
- Lightweight spackle or spackling paste
- Putty knife (3-inch)
- Fine-grit sandpaper (220 grit)
For Medium Holes (1-6 Inches)
- Self-adhesive mesh patch
- Joint compound (also called drywall mud)
- Putty knife (6-inch)
- Sandpaper (150 and 220 grit)
For Large Holes (Over 6 Inches)
- Drywall scrap (matching thickness)
- Scrap wood for backing (1x2 or 1x3)
- Drywall screws
- Drywall tape (paper or mesh)
- Joint compound and a taping knife
- Drywall saw or utility knife
Fixing Small Holes (Nail Holes, Screw Holes)
Small holes are the easiest repair on this list. Press a small amount of spackle into the hole with your putty knife, slightly overfilling it. Let it dry according to the package instructions — usually 30 minutes to a few hours — then sand flush with 220-grit sandpaper. A single coat is usually enough; if the spackle shrinks slightly as it dries, apply a thin second coat and sand again.
Fixing Medium Holes (Doorknob Dents, Small Impact Damage)
For holes too big for spackle alone but too small to need a full drywall patch, a self-adhesive mesh patch is the fastest reliable fix.
Step 1: Clean the Area
Remove any loose or crumbling drywall paper and debris around the hole so the patch has clean surface contact.
Step 2: Apply the Mesh Patch
Center the self-adhesive mesh patch directly over the hole and press it firmly against the wall — it should stick on its own without additional adhesive.
Step 3: Apply Joint Compound
Using a 6-inch putty knife, spread joint compound over the patch, feathering the edges outward so the repair blends into the surrounding wall. Let it dry fully (check the product for dry time — usually 24 hours).
Step 4: Sand and Repeat
Sand smooth with 150-grit, then apply a thin second coat to fill any remaining texture, feathering even wider than the first coat. Let dry, then finish with 220-grit sandpaper until the area is flush and smooth to the touch.
Fixing Large Holes (Furniture Damage, Doorknob-Through-Wall)
Large holes need an actual piece of new drywall, backed by something solid to screw into — this is the closest DIY drywall repair gets to a full patch job, but it's still very doable.
Step 1: Square Off the Hole
Use a drywall saw to cut the damaged area into a clean square or rectangle — this makes it much easier to cut a matching patch piece.
Step 2: Add Backing Support
Cut two pieces of scrap wood a few inches longer than the hole's height. Insert them behind the drywall on each side of the opening, holding half outside the hole, and screw through the existing drywall into the wood to secure it in place. This gives the patch something to be screwed into.
Step 3: Cut and Install the Patch
Cut a piece of new drywall to match the size of the hole exactly. Screw it into the backing boards you just installed, driving screws flush (not overdriven — that tears the paper and weakens the hold).
Step 4: Tape the Seams
Apply drywall tape over all four seams where the new patch meets the old wall, bedding it into a layer of joint compound underneath.
Step 5: Mud, Dry, Sand — Repeat
Apply joint compound over the taped seams, feathering the edges wide. Let dry, sand, and apply a second (and often third) coat, each one feathered slightly wider than the last, until the seams disappear into the wall.
Finishing Touches
Once your repair is sanded smooth, wipe away dust with a slightly damp cloth before priming. Always prime the patched area before painting — joint compound absorbs paint differently than the surrounding wall, and skipping primer is the most common reason a "perfect" patch still shows through under fresh paint.

A Smooth Wall Is Closer Than You Think
Drywall repair looks intimidating mostly because of the drying and sanding steps — the actual technique is simple and forgiving. Match the method to the size of the hole, don't rush the drying time between coats, and you'll end up with a wall that looks like the damage never happened.
