Drywall alone holds more than people think - if you use the right anchor. Weigh the frame, pick from three tiers, and stop asking one bare nail to do a wall anchor's job.

Bathroom-scale the frame (weigh yourself with and without it). Under 2kg - most small and medium frames - barely needs hardware at all. Two to 10kg covers large framed prints and mirrors. Beyond 10 to 15kg - big mirrors, shelves, a TV - you are in heavy-anchor or find-a-stud-anyway territory.
Every anchor package states a weight rating; treat the printed number as its ceiling under ideal conditions and aim to use anchors at half their rating. And the ratings assume static, straight-down load - anything that gets pulled, leaned on, or holds moving weight (shelves, coat hooks, TV arms) needs the next tier up or a stud.
Adhesive strips (Command and similar) hold remarkably well when used by the letter: clean the wall with isopropyl alcohol first - not household spray cleaner, which leaves residue - press each strip for 30 seconds, then wait an hour before hanging the frame. Most failures are skipped prep, not failed adhesive.
Use the picture-hanging variants with interlocking velcro-style strips, add a pair more than the box minimum, and respect the limits: fresh paint needs weeks to cure first, textured and unpainted surfaces are out, and so are steamy bathroom walls. For renters this tier is the whole game - zero patching at move-out.
The classic ribbed plastic plug is the weakest common anchor and the one most likely to spin loose or pull out - skip it in plasterboard. The better defaults: self-drilling threaded anchors (the big screw-like ones, often nylon or zinc) that screw straight into drywall with a hand screwdriver and hold 10 to 25kg, or molly bolts that expand behind the board.
Installation rule for self-drillers: no pilot hole needed in plain drywall - drive it until the flange sits flush, then run the screw in, stopping when snug. Over-tightening strips the drywall thread it just cut, which is how a 20kg-rated anchor becomes a 2kg one. If the anchor ever spins without biting, stop: upsize to a toggle in the same hole rather than re-cranking.
Above 25kg, or for anything pulled away from the wall, use toggle bolts or snap toggles - wings that open behind the drywall and clamp against its back face, holding 40kg+ in good board. They need a bigger drilled hole and a moment of threading, and they are the strongest thing drywall alone can offer. Heavier than that: find a stud or rethink the placement.
For hanging itself: use two hooks spaced apart instead of one - frames on a single point tilt every time the door slams. Mark heights with painter's tape across the frame's hanging hardware, transfer the tape to the wall with a level, and you get both hooks right the first time. Gallery height rule of thumb: picture center at about 145 to 152cm (57-60 inches) from the floor.
Cables run vertically above and below outlets and switches, and pipes run vertically from taps and radiators - never drill directly in line with any of them. A cheap multi-scanner that detects live wire and metal costs about $20 and takes ten seconds per hole; it is the difference between a picture and an electrician's call-out.
Old, crumbly, or previously patched walls derate every anchor. If the drill bit goes in with no resistance or the dust is powdery rather than chalky-white, downgrade your weight expectations or move 10cm - you may be in an old patch or failing plaster, neither of which holds a rated load.
With the right anchor, more than most frames need: self-drilling anchors hold 10-25kg, toggles 40kg or more in sound board. Bare nails and plastic plugs are the weak links, not the drywall itself.
Adhesive strips up to about 7kg, used exactly per instructions on alcohol-cleaned walls. Above that, one small self-drilling anchor hole patches in five minutes with spackle at move-out - often less visible than the wall scuffs around it.
Usually one of three: a plastic plug doing an anchor's job, an over-tightened screw that stripped the drywall thread, or a load that pulls outward (shelf, hook) on an anchor rated for straight-down weight. Replace with a toggle one size up - in a fresh spot, since the old hole is compromised.
Two-point hanging on two toggle anchors, or a French cleat rated above the mirror's weight - cleats spread load beautifully and self-level. Over 20kg, or above a bed or sofa, find studs for at least one fixing point. Falling mirrors are the failure you do not get to retry.
