Beginner's Guide to Hanging Pictures and Gallery Walls

The first hole is the awkward one. Everything after that is just measuring. Most pictures look wrong for one of three reasons: they hang too high, they float above the furniture instead of relating to it, or the gaps in a group drift wider on one side than the other. None of that is about taste, and all of it is fixable with a tape measure, a pencil and half an hour.

Here is how to hang a single frame well, and how to build a gallery wall that looks deliberate rather than accidental.

Plan the arrangement on the wall, not in your head

Cut paper templates to the size of each frame and tape them up before anything gets drilled. It feels like a fussy extra step. It is also the quickest way to discover that the picture you had in mind is 10 cm too wide for the gap beside the door.

Walk past the templates for a day. Sit on the sofa and look at them. Check them from the doorway, which is how most visitors will see the room. Move things about while the only cost is a strip of masking tape.

Pay attention to what sits underneath. A picture above a sofa should relate to the sofa rather than hover near the ceiling: leave roughly 15–25 cm between the sofa back and the bottom edge of the frame, and let the artwork span about two-thirds of the sofa's width. Above a bed, much the same idea, with a slightly tighter gap to the headboard. In a hallway or up a stairwell, ignore the furniture and treat the staircase itself as the composition.

Get the height right

Galleries and museums generally centre art at about 145 cm from the floor, which is close to average eye level. It is a good default because it works in almost any room and keeps a row of frames consistent as you move through the house.

Measure to the centre of the frame, not the top. Half of all wonky picture walls come down to someone measuring to the wrong edge.

Two exceptions are worth knowing. In rooms where you are mostly seated — a dining room, a snug — you can drop the centre line by 5–10 cm so the art meets your eye at the table. In tall spaces and stairwells, raise it. If you are hanging a group, treat the whole group as one picture and put its centre at 145 cm.

Ceilings and picture rails are unreliable reference points; older houses slope. Use a spirit level, and take your measurement up from the floor every time.

Spacing and layout for gallery walls

Aim for 5–8 cm between frames in a group. That reads as deliberate: much under 4 cm looks crowded, much over 10 cm and the pieces stop feeling related. Pick a number and keep it throughout.

The grid

Matching frames in even rows. Align the outer edges of the whole block and keep the vertical and horizontal gaps identical. This is the easiest layout to hang well and the most forgiving if you want to add to it later.

The loose arrangement

Mixed sizes and frames, built around one anchor piece. Put the largest frame slightly off-centre, then work outwards, balancing weight rather than chasing symmetry — a big dark frame on one side wants a couple of smaller ones opposite it. Keep the gaps consistent and the whole thing will look intentional.

The picture ledge

A shallow shelf holds frames, prints and small objects, needs two holes instead of twenty, and lets you rearrange everything in five minutes. Ideal for renters, and for anyone who changes their mind.

The kit worth having

• A metal tape measure and a 600 mm spirit level.
• A pencil, a rubber and a roll of low-tack masking tape.
• Paper and scissors for templates.
• A hammer, plus a drill with masonry and wood bits.
• Picture hooks in two or three sizes, wall plugs and hollow-wall fixings.
• D-rings and picture wire for heavier frames.
• A step ladder tall enough that you are not stretching.

Match the fixing to the wall and the weight

Most small and medium frames — up to about 2 kg — are fine on a single picture hook with two pins. Anything heavier, or wider than roughly 60 cm, hangs better on two hooks spaced about a third of the frame's width in from each side, which stops it see-sawing on the wall.

Then think about what is behind the plaster. In modern plasterboard, use a hollow-wall fixing rated for the load rather than trusting a hook on its own. In brick or stone, drill, plug and screw. In older lath-and-plaster walls, fixings can be unpredictable, so either find a stud or spread the load across two points. If a piece is genuinely heavy or valuable, or the wall is unusual, it is worth asking a professional picture hanger — they carry the right fixings for awkward walls and cover the work.

Mark, drill, hang

1. Mark the centre line for the frame or the group at your chosen height.
2. Hold the frame against the wall, or use the template, and mark where the fixing needs to sit — allowing for the drop of the wire or hook.
3. Check the marks with a spirit level before drilling. Then check them again.
4. Drill, insert the fixing, and tap the hook home gently.
5. Hang it, step back three metres, and check the gap or the level line from there.

With wire, pull it into a shallow V rather than a tight triangle. A nearly horizontal wire lets the frame sit flush against the wall and stops it drifting sideways. A wrap of tape over the twisted ends saves scratched paint.

After hanging: the small adjustments

Stand where you will actually sit and look at it. A row that seemed level from the doorway often shows its true self from the sofa. If a frame leans out at the top, a small felt pad on the bottom corners will pull it back flat.

Then leave it alone for a week. If something still nags at you, it is nearly always a gap that is 2 cm out or a bottom edge that needs lifting. Moving one hook is a ten-minute job, and it is the difference between a wall of pictures and a wall that looks finished.
