How to hang pictures and mirrors yourself
Half an hour a picture. €3–€20 in hooks and fixings.
Find the wall type, pick the fixing for the weight, avoid cables and pipes, and hang it level — pictures to heavy mirrors.
- Every step, start to finish
- Checked October 2026 — sources at the end
- Honest about when to call a pro
FIRST, THE HONEST ANSWER
Do it yourself, or get a handymen?
Do it yourself if…
- You are hanging framed pictures, prints or a mirror on an ordinary interior wall
- You can drill a hole with a household drill and stand safely on a step-ladder
- You know, or can find out, roughly what the frame or mirror weighs
- The wall is plaster on block or brick, plasterboard on studs, or plasterboard stuck to masonry
Get a pro if…
- The mirror is very large or heavy enough to need two people to hold it at height
- The wall is old lath and plaster that crumbles when you test it, or tiled
- You need to fix over a staircase or a drop where a step-ladder will not stand safely
- The wall may hide pipes or cables you cannot trace, such as above a kitchen counter or around a consumer unit
Safety first
- Check for cables and pipes before every hole, and keep away from the lines that run straight from sockets, switches, radiators and taps.
- Wear safety glasses when you drill. Masonry dust and flakes of plaster fly at eye height.
- On a step-ladder, the HSA’s rule is not to stand on the top two steps, keep your belt buckle inside the stiles and face the work instead of reaching sideways.
- Large mirrors are heavy and dangerous if they break. Lift with a helper, wear gloves, and never hang one over a bed or a cot on doubtful fixings.
- If you drill into a cable, do not touch the drill bit or the wall. Switch off at the fuse board and call a Registered Electrical Contractor.
| MATERIAL | COVERAGE | FOR THIS JOB |
|---|---|---|
| Picture hooks | Single, double or triple, by frame weight | One or two per light frame |
| Wall plugs and screws | Sized to the wall and the load, from the plug maker’s table | Two per frame or mirror |
| Cavity fixings | Metal cavity anchors or spring toggles for plasterboard | Two or more for a heavier mirror on plasterboard |
| D-rings or mirror plates | A pair, with short screws for the frame | One pair per frame |
How much weight is on each fixing?
Weigh the mirror, then divide by the number of fixings and compare the result with the plug maker’s figure for your wall, leaving a wide margin. A 16 kg mirror on two fixings puts 8 kg on each. In 12.5 mm plasterboard, where one universal plug lists a maximum of 15 kg, that is too close for comfort: use metal cavity anchors, add a third fixing on a cleat, or find the studs.
Maker figures are tested maximums in good material. Old plaster, hollow block and damp walls hold less.
A brass picture hook with a hardened pin is tapped in at an angle and holds a light frame in sound plaster without drilling. Double and triple hooks spread the load for medium frames. They are the neatest option and leave the smallest hole, but they rely on the plaster being firm; in crumbly plaster or plasterboard they pull out.
In block, brick or concrete, a drilled hole with a nylon plug and a screw is the standard fixing. One fixing maker’s universal plug in its 6 mm size takes a 4.0 - 5.0 mm screw, needs a hole at least 40 mm deep, and lists maximum loads of 50 kg in solid brick and 95 kg in concrete. Those maximums fall sharply in hollow brick and aerated block, so the wall type matters as much as the plug.
A plain plug in plasterboard simply spins. The same maker’s universal plug, in the 6 mm size, lists a maximum of 15 kg in 12.5 mm plasterboard, because it folds and knots behind the board. For anything heavier, use a metal cavity anchor or a spring toggle that grips the back of the board, or, best of all, screw straight into a timber stud behind it.
How the frame hangs matters too. Two D-rings on the back, each on its own hook or screw, hold a frame level and stop it swinging. A single wire is easy but lets the frame tilt. For a heavy mirror, a split batten or French cleat — one bevelled strip on the wall, its partner on the frame — spreads the weight across several fixings and lets you lift the mirror into place.
A large mirror is heavy, sharp if it breaks, and awkward at height. Weigh it, then choose fixings that carry it with a generous margin, use at least two of them, and prefer studs or masonry to bare plasterboard. Mirror screws through the frame, mirror plates or a cleat are all better than one hook.
THE PART THAT DECIDES THE FINISH
Preparing the wall — by what you are fixing into
Find out what the wall is before you choose anything. Knock along it, drill a small test hole somewhere hidden if you need to, and pick the card that matches.
Plaster on block or brick
Sounds solid when you knock, and the drill dust comes out red, grey or orange.
- Run the cable and pipe detector over the area, and avoid the zones straight above, below and beside sockets and switches
- Put a strip of masking tape where you will drill and mark the hole on it
- Use a masonry bit of the size on the plug pack, drill to the depth it states, and vacuum the dust out
- Tap the plug in flush; if it sits loose, the hole is too big — move a few centimetres and drill again
Plasterboard on timber or metal studs
Sounds hollow between firm spots spaced along the wall; drill dust is white and powdery.
- Find the studs with the detector or a fine bradawl and mark their centres
- If the fixing lands on a stud, use a wood screw straight into it — the strongest option
- Between studs, use a plasterboard plug for light loads or a cavity anchor or toggle for heavier ones
- Check the board is sound and not damp or crumbling around the hole
Plasterboard stuck onto masonry
Sounds hollow in patches and solid in others, with a narrow gap behind the board.
- Expect the board to sit on adhesive dabs with a small void behind
- For light frames, a plasterboard fixing works; for heavy mirrors, drill through into the masonry behind
- Use a plug long enough to reach well into the block, not just the board
- Do not overtighten — the board crushes into the gap and dimples
Old lath-and-plaster or crumbly plaster
Common in older houses: plaster on thin wooden strips, often uneven and fragile.
- Test with a picture hook first; if the plaster cracks around it, the wall needs a better fixing
- Find the timber studs behind the laths and fix into those for anything heavy
- Drill slowly without hammer action so the plaster does not break away
- Spread heavy loads with a batten fixed across two studs
THE JOB
How to hang a picture or mirror, in order
Identify the wall and check for cables and pipes
10 minKnock along the wall and listen for solid or hollow. Work out which card above matches your wall. Run the detector slowly over the whole area you plan to use, in both directions, and mark anything it finds with masking tape. Cables usually run straight up and down or across from sockets and switches, and pipes run to radiators, taps and boilers. Keep well clear of those lines.
- Check the detector on a wall where you know a cable runs, so you trust its reading
- Above a kitchen counter or a bathroom basin, assume pipes are present until proven otherwise
- In plasterboard, find two studs to work out the spacing; the rest follow the same pattern
Mistake to avoid: Drilling straight above or below a socket. It is the most likely place for a cable, and hitting one is dangerous.
Choose the fixing for the wall and the weight
10 minWeigh the picture or mirror. Read the load table on the fixing pack for your wall type and pick a fixing that carries the weight with a wide margin, using at least two fixings for anything heavier than a small frame. Check the drill size and hole depth the maker gives, and fit the right bit to the drill now so you are not guessing later.
- The maker’s table lists separate figures for concrete, solid brick, hollow brick, aerated block and plasterboard — use the right line
- Use the screw size the plug asks for; too thin a screw will not expand the plug
- Buy one more fixing than you need, in case a hole goes wrong
Mistake to avoid: Picking the fixing by the hole you happen to have. A plug in the wrong wall or with the wrong screw pulls straight out.
Decide the height and mark the position
15 minHold the frame against the wall with a helper, or cut a paper template to its size and tape it up. Gallery practice is to put the centre of a picture at around eye level, but over a sofa or sideboard, keep a hand’s width or so between the furniture and the frame. Measure from the top of the frame down to the hanging point — the taut wire or the D-ring — and mark the fixing point on masking tape on the wall.
- For two D-rings, measure the distance between them and mark both points on a level line
- Paper templates on the wall let you plan a group of frames before you drill a single hole
- Mark with pencil on tape, never pen on the wall
Mistake to avoid: Marking the top of the frame instead of the hanging point. The picture ends up higher than you planned by the depth of the wire’s drop.
Level the marks
5 minFor a single hook, the level matters less than the hanging point. For two fixings, lay the spirit level along a line through both marks and adjust until the bubble sits dead centre. For a row of frames, draw a light level line on tape the full length, or use a laser level, and measure each frame’s fixing point from it.
- Check the level both ways round — a cheap level can read differently when flipped
- Measure frame spacing from centre to centre, not edge to edge
- Keep the same gap between frames in a group
Mistake to avoid: Levelling the frame by eye against a ceiling or skirting. Old houses are rarely square, and the frame looks crooked against the level.
Drill the holes
10 minPut on safety glasses. Hold the drill square to the wall and start slowly on the masking tape so the bit does not skate. In masonry, use the hammer setting once the hole has started; in plasterboard and old plaster, never use hammer action. Drill to the depth on the fixing pack — a strip of tape wrapped round the bit marks it — and vacuum the dust out of the hole.
- Hold the vacuum nozzle under the drill to catch dust as you go
- If the bit suddenly drops through, you have hit a cavity — switch to a cavity fixing
- If the bit stops dead on something hard and metallic, stop: it may be a pipe or a cable conduit
Mistake to avoid: Using hammer action on plasterboard. It blows a ragged hole that no plug can grip.
Fit the plugs or cavity fixings
10 minPush or tap each plug in until it sits flush with the wall surface. For a metal cavity anchor, push it through the board and tighten it, or pull it tight with its setting tool, so the legs fold up behind the board before the screw goes in for good. For a spring toggle, thread the hook or bracket onto the bolt first, then fold the toggle and push it through the hole until it springs open behind.
- A plug that spins needs a new hole, not a matchstick
- Set metal cavity anchors fully before hanging anything; a half-set anchor holds very little
- Leave the screw slightly proud if the frame hangs on its head
Mistake to avoid: Hanging the weight on a cavity anchor before it has been set. The legs never open and the fixing pulls straight out.
Fix the hooks or screws and hang the frame
10 minDrive the screws into the plugs until they are firm, leaving the head standing out just enough to take the D-ring or wire, or fix the hook or mirror plate. For a pin picture hook, hold the hook against the wall and tap the pin in at the angle the hook sets. Hang the frame, with a helper for anything heavy, and check it is level with the spirit level on top.
- Two people lift a heavy mirror; one guides it onto the fixings while the other takes the weight
- Small felt pads on the bottom corners stop the frame marking the wall and help it hang straight
- Tug gently downwards on the frame to check the fixings before you let go fully
Mistake to avoid: Driving the screw fully home and then trying to loop the wire over it. There is no room, and the wire slips off.
Fine-tune and tidy
10 minStep back across the room and look. Small tilts on a wire are corrected by sliding the wire on the hook; on two D-rings, by adjusting a screw a turn. Peel off the masking tape, vacuum any dust off the skirting, and fill any wrong holes with a little filler.
- A blob of removable putty behind a bottom corner stops a frame drifting
- Keep the leftover fixings with the frame’s receipt for the next move
- Check a heavy mirror again after a day; settle-in movement shows up early
Mistake to avoid: Leaving a heavy mirror on fixings you were not sure of. If you doubt them now, change them now.
The mistakes that make it worse
- Drilling without checking for cables and pipes
- Using a solid-wall plug in plasterboard
- Trusting the maximum load on the pack with no margin
- Hanging a heavy mirror on one hook
- Using hammer action on plasterboard or old plaster
Stop here and get a picture and mirror hanging pro
- The mirror is too heavy or too large for two people to lift and hold safely
- The wall is crumbling, tiled or hides services you cannot trace
- The spot is over a stairwell or a drop where a step-ladder will not stand safely
- You have drilled into a cable or a pipe
| WHAT YOU SEE | WHY, AND THE FIX |
|---|---|
| Wall plug spins in the hole | The hole is too big, or it is plasterboard and needs a cavity fixing. Move a few centimetres and drill a fresh hole with the right bit, or switch to a plasterboard fixing. |
| Picture keeps tilting | A single wire lets the frame swing. Hang it on two D-rings and two fixings, or add a dab of removable putty behind a bottom corner. |
| Plaster cracked or fell out round the hook | The plaster is crumbly or the frame is too heavy for a pin hook. Fill the hole, then drill and plug, or fix into a stud. |
| Drill keeps skating on the paint | Start slowly on masking tape, or make a small dent first with a nail or bradawl. |
| Hit something hard and metallic | Stop drilling. It may be a pipe, a cable or a metal plate protecting one. Move well away and check with the detector. |
| Mirror pulled away from plasterboard | The fixings were not rated for the weight in plasterboard. Use metal cavity anchors, a cleat across several fixings, or the studs. |
| Frame hangs crooked after a day | Fixings have settled or the wire has slipped. Re-level, and switch to two fixings if it happens again. |

The fixings cost little; the detector is the one tool worth buying if you do not own one, because it saves you from the expensive mistake.
RATHER NOT?

Or post the job free and let them come to you.
Look at the fixings and the frame after a week. A heavy mirror should not have moved at all.
Put the leftover plugs and screws in a bag taped to the back of the frame for the next move.
Cardboard and clean packaging go in the recycling bin. Broken mirror glass is not the same as bottle-bank glass, which is for bottles and jars: wrap it well, mark it, and ask your civic amenity site or check mywaste.ie for what to do with it.
A little ready-mixed filler, sanded flush, hides the holes; touch up with the wall colour.
Hanging pictures and mirrors: questions people ask
A common rule is to put the centre of the picture around eye level, and over furniture to leave a hand’s width or so between the furniture and the frame. Templates cut from paper let you test it before drilling.
Screw into the timber studs behind the board if you can. If not, use metal cavity anchors or spring toggles, two or more, and leave a wide margin below the maker’s load figure.
No. It spins and pulls out. Use a plug designed for plasterboard for light loads, or a cavity anchor or toggle for heavier ones. One maker’s universal plug lists 15 kg in 12.5 mm plasterboard in its 6 mm size.
Use a detector that finds live cables, keep away from the lines running from sockets and switches, and stop if the drill hits something metallic.
Not for a light frame on firm plaster — a pin picture hook tapped in at its angle is enough. Heavier frames, mirrors and plasterboard walls need drilled fixings.
On the Locufy price guide for Ireland, hanging costs €40–€120 per hour, typically €60. A couple of mirrors and a few frames usually take an hour or two.
