Hanging Things on the Wall So They Stay There

Empty the wall before you buy the anchor. That sounds backward, but the single most common reason something falls off a wall is that the person hanging it picked the hardware before knowing what was behind the plaster, how heavy the thing actually was, and whether it would be pulling down or pulling out. Five minutes of checking beats a shelf on the floor and two holes to patch.

I have hung a lot of things badly. The one I still think about is a spice shelf in my first rental that came off the kitchen wall on a Sunday morning and took eleven jars with it. The shelf was light. The jars were not, and I had used the small plastic anchors that came in the box, which are made for picture frames and not for a shelf carrying several pounds of glass.

The two questions that decide everything

Before you touch a drill, answer these.

What is the wall made of? Tap it. Hollow drywall gives a light, papery sound and feels slightly soft when you press a thumbnail into it. Plaster over wood lath sounds duller and feels rock hard. Masonry, brick, or concrete sounds dead and gives nothing at all. Tile is a surface over one of the others, so what matters is what is behind it. Each of these needs different hardware and there is no anchor that handles all four well.

Which direction is the load pulling? A framed picture hangs close to the wall and pulls almost straight down, which is called shear load. A shelf, a coat rack, or a wall mounted TV arm holds weight out from the wall and tries to lever the top fastener out toward you. That is pull out load, and it is much harder on an anchor. Manufacturers rate anchors for both, and the pull out number is always the smaller one.

Find the framing first, every time

Nothing beats a screw driven into solid wood framing. Studs in most homes sit either sixteen or twenty four inches apart, measured center to center, and once you find one the rest of the wall follows that spacing.

An electronic stud finder works if you calibrate it on a blank section of wall and sweep slowly, twice, from both directions, marking where it reads on each pass. The middle of your two marks is the center. The low tech method is to look for the electrical boxes, because outlets and switches are almost always screwed to the side of a stud. Measure from there in sixteen inch steps and probe with a small finish nail in a spot you will cover.

If you find framing where you need it, the job is nearly over. Drill a pilot hole slightly smaller than the screw shank and drive a wood screw long enough to go at least an inch and a quarter into the stud after passing through whatever you are hanging.

When there is no stud where you need one

This is the normal case, and it is why anchors exist. Here is how I choose.

Light things on drywall

For picture frames and anything under roughly ten pounds hanging flat against the wall, hardened steel picture hooks with an angled nail are excellent and leave a tiny hole. Threaded plastic or metal self drilling anchors also work and go in with a screwdriver. Skip the small tapered plastic plugs that come free in the box with most items. They are the weakest thing sold and they are the reason my spice shelf failed.

Medium weight and anything that sticks out from the wall

Toggle style anchors are the answer here. The classic version has spring wings that fold flat to go through a hole and then open behind the drywall, spreading the load across a wide area. The newer strap toggles do the same with a plastic strap that snaps off flush and are easier to install one handed. Both hold far more than they look like they should, and both are what I use for towel bars, floating shelves, and coat hooks.

One thing to understand about the classic winged toggle: if you remove the screw, the wings drop inside the wall and are gone. Have the item on the screw before you push the toggle through, not after.

Heavy things

For anything that would hurt if it fell, hit framing or do not hang it. Heavy mirrors, cabinets, TVs, and shelving carrying books belong on studs, or on a piece of wood that spans two studs and is then used as the mounting surface. That backing board approach is how I hung a set of shelves in a spot where the studs did not line up with the design, and it has held for four years.

Plaster, brick, and tile

Old plaster is brittle and crumbles at the edge of a hole. Put a piece of painter’s tape over the spot before drilling to hold the surface together, and use a drill setting without hammer action. For brick, block, or concrete, you need a masonry bit and a sleeve or wedge anchor sized for the hole. In tile, drill through the glaze slowly with a bit made for tile, no hammer, and keep the tip cool with a little water. Once you are through the glaze, switch to whatever the material behind requires.

What is behind the wall matters more than the anchor

Before drilling anywhere, especially near a kitchen or bathroom, think about what runs inside. Electrical cable often runs vertically up from an outlet and horizontally between boxes. Plumbing runs up from below in wet walls. If you are drilling within a foot or so of an outlet, a switch, or the wall behind a sink or a shower, be careful about depth and consider a stud finder with live wire detection.

If a drill suddenly gets easy or the bit grabs, stop and pull it out. Guessing at that moment is how small jobs become expensive ones.

Anything that involves moving electrical wiring or plumbing belongs with a licensed electrician or plumber. Hanging something on a wall is a homeowner job. Working on what is inside the wall is not.

Getting it level and where you actually want it

Measuring from the ceiling is a mistake in older houses because ceilings are rarely level. Measure from the floor, and even then check with a level rather than trusting the number.

For pictures, the common guidance is to put the center of the image around eye height, which for most people lands close to fifty seven or fifty eight inches from the floor. Over a sofa or a console, hang lower than instinct suggests so the piece relates to the furniture rather than floating.

The technique that saves the most frustration: cut a piece of paper to the size of the item, tape it up, and live with it for a day. I do this for anything going in a room I sit in every evening, because the right spot on a Tuesday afternoon is sometimes the wrong spot when the lamps are on.

For a two hook frame, measure the distance between the hooks on the back, transfer that to a strip of tape stuck to the wall, and drill through the tape. The tape holds the measurement and it catches the dust.

Fixing what pulled out

When an anchor tears out of drywall it usually takes a chunk of the paper face with it, so you cannot simply put a new anchor in the same hole. Two options. Move over an inch or two and start clean, patching the old hole afterward. Or repair the hole properly first with a self adhesive mesh patch and joint compound, let it cure, and then anchor into fresh material. The second takes a day of drying time and is the right call if the location matters.

The one thing not to do is put a bigger anchor into a blown out hole. There is nothing left for it to grab, and it will fail again in the same spot, usually faster.

A small kit that covers most of a house

I keep hanging hardware in one small box so I am not searching mid job: a handful of picture hooks in two sizes, a card of strap toggles, a few wood screws in two lengths, a stud finder, a short level, a pencil, and a roll of painter’s tape. That box has handled almost everything I have hung in this house, and having it in one place is the difference between hanging the thing on a Saturday and leaving it leaning against the wall until March.
