Steps
Weigh the mirror on a bathroom scale or check the packaging. Buy toggle bolts or heavy duty anchors rated for at least twice that weight, because plaster on its own will not hold a screw.
Run a stud finder across the wall and mark any solid spots. Old plaster over lath confuses many finders, so slide a strong magnet along the wall to catch the hidden lath nails.
Measure from the top of the frame down to its hangers. Mark that distance plus your chosen height on the wall, then draw a level line and mark the two fixing points.
Drill through the plaster with a masonry bit at low speed and no hammer action. Ease off as the bit breaks through so you do not blow out a chunk of plaster.
Push each toggle bolt through its hole and let the metal wings spring open behind the wall. Slide the bracket or hanger on and tighten until it grips firmly.
Screw D-ring hangers or a French cleat to the mirror frame with screws long enough to bite into solid wood, not just the decorative edge.
Lift the mirror with a helper and hook it onto the bolts or cleat. Hold a spirit level against the frame and adjust the hangers until it sits straight.
Fix a small screw or a dab of picture putty under the bottom corners to stop the mirror swinging when a door slams.
Tips and common mistakes
Two anchors set wide apart near the frame edges hold far more than one fixing in the centre.
Skip plastic expansion plugs in old plaster, as they crumble the keys and pull out under load.
Wear safety glasses and drill slowly, or the plaster around the hole will crack and crumble.
Do not hang a heavy mirror above a bed or sofa unless you add a safety strap to the frame.
Questions
Can plaster hold a heavy mirror without a stud?
Only with fixings that spread the load behind the wall, such as toggle bolts. The plaster surface is brittle, so the anchor has to grip the lath or the cavity behind it.
How do I pick the right anchor?
Match the anchor's stated load rating to the mirror's weight and leave a generous margin. If the mirror is very heavy, use a French cleat fixed with several toggle bolts.
What if the wall crumbles when I drill?
Stop and move the fixing point a few centimetres sideways. If the plaster is loose over a large area, use a floor standing mirror instead of risking a fall.
