How to Hang Anything on Any Wall

What Type of Wall Do You Have?

Drywall (most common): knock on the wall. Sounds hollow between studs, solid on studs. Drywall is 1/2 inch or 5/8 inch thick gypsum board. It holds very little weight on its own (under 5 pounds per fastener). Everything heavier than a small picture frame needs either a stud or a proper anchor.

Plaster (pre-1960s homes): harder, denser than drywall. Usually 3/4 to 1 inch thick over wood lath strips. Plaster cracks easily if you drill aggressively. Drill slowly, don't use hammer drill mode. Standard drywall anchors work in plaster but expansion anchors can crack the surrounding plaster. Toggle bolts are the safest option for heavy items.

Brick or concrete block: requires a hammer drill with masonry bits. Anchoring is done with plastic expansion anchors (for light loads) or concrete sleeve anchors or Tapcon screws (for heavy loads). Pre-drill the hole to the exact anchor diameter.

Concrete (poured, basement walls): requires a rotary hammer with SDS bits for efficient drilling. Same anchor types as brick but the material is harder. Tapcon screws are the go-to for moderate loads. Wedge anchors for heavy loads (TVs, shelves holding books).

Wood paneling or thin veneer: paneling over drywall needs a fastener long enough to reach the drywall or stud behind it. Paneling alone won't hold anything heavy.

Finding Studs

Electronic stud finder: the standard method. Slide it across the wall with the button held down. It beeps or lights up at stud edges. Run it from both directions to find both edges of the stud, then mark the center. Studs are typically 16 inches on center (measure from a corner to verify your home's spacing).

Magnet method: a strong rare-earth magnet finds the drywall screws or nails that attach the drywall to the studs. Slide it along the wall until it sticks. Mark the spot. Move up or down to find another fastener in the same stud line. This confirms the stud location and direction.

Knock test: tap the wall while moving horizontally. The sound changes from hollow to solid at stud locations. Less precise than a finder but works in a pinch.

Measure from a known point: studs are usually 16 inches on center (sometimes 24 inches). If you find one stud, measure 16 inches to find the next. Electrical outlets are almost always mounted on the side of a stud, so the stud is either 3/4 inch to the left or right of the box edge.

Anchors by Weight Capacity

Under 10 pounds (small picture frames, hooks): a nail angled at 45 degrees into drywall holds 5 to 10 pounds. A small plastic expansion anchor holds 10 to 15 pounds. For plaster, use a picture hook with a hardened nail designed for plaster walls.

10 to 25 pounds (medium frames, small shelves, towel bars): self-drilling anchors (zinc, screw-in type) hold 25 to 50 pounds in drywall. These have a sharp point and coarse threads that cut into the gypsum. No pre-drill needed. The anchor creates its own pilot hole.

25 to 50 pounds (heavy mirrors, medium shelves, coat racks): toggle bolts (spring-loaded wings that open behind the wall) hold 50 to 100+ pounds in drywall. Snap-toggle anchors are easier to install than traditional toggle bolts because you can remove and reinsert the bolt without losing the toggle.

Over 50 pounds (TVs, bookshelves, grab bars): go into studs. No drywall anchor is as reliable as a screw driven into a stud. A single 3-inch lag screw in a stud holds 100+ pounds of shear force. For TV mounts, use at least 2 lag screws per stud, into at least 2 studs.

For grab bars (bathrooms): always into studs or use wing-it toggle bolts rated for grab-bar loads. A grab bar that pulls out of the wall when someone grabs it during a fall is a serious injury risk. This is not the place for drywall anchors.

Tools You Need

Level (24-inch or laser). Nothing looks worse than a crooked picture or shelf. For a single item, a torpedo level is fine. For multiple items in a row (gallery wall), a laser level projects a straight line across the whole wall.

Stud finder ($15 to $50). Electronic for general use, magnetic as a backup or verification.

Cordless drill/driver. For driving screws into studs and pre-drilling for anchors. Set the clutch low when driving into drywall to avoid overdriving.

Drill bits: standard twist bits for drywall and wood, masonry bits for brick and concrete. A set with sizes from 3/16 to 1/2 inch covers all common anchors.

Hammer: for picture hooks, nail-in anchors, and tapping masonry anchors into pre-drilled holes.

Tape measure and pencil. For marking height, centering items, and laying out multi-piece arrangements.

Painter's tape: place tape on the wall before drilling to prevent drywall or plaster from chipping around the hole. Also useful for mocking up gallery wall arrangements before committing to holes.

Common Mistakes

Using a drywall anchor for a TV mount. Even the heaviest-rated drywall anchors are not designed for the dynamic, leveraged load of a TV on an articulating mount. A 50-pound TV on a 24-inch arm creates over 100 pounds of pull force on the top anchors. Go into studs.

Hanging heavy items on a single point. Two fasteners 16 inches apart are stronger than one fastener rated for twice the weight. The second fastener prevents rotation and distributes the load.

Not checking for pipes and wires. Before drilling, check for plumbing (especially in bathroom walls and kitchen walls near sinks) and electrical wiring (typically runs vertically from outlets and switches to the ceiling). A stud finder with AC wire detection helps. When in doubt, drill shallow and check.

Over-tightening anchors. An expansion anchor that's cranked too tight crushes the drywall around it, reducing its holding power. Tighten until snug, then stop. If the anchor spins freely, the hole is stripped and you need a larger anchor or a different location.
