Spacing wall art: the numbers to use, and the measurement nearly everybody gets wrong

3 November 2026 · 6 min read

Most wall art is hung too high, too far apart, and about two centimetres off where the person intended, because the hook went where the top of the frame was supposed to be rather than where the wire sits when it is loaded. All three problems have numbers attached. The numbers are not aesthetic opinions, they come from gallery practice and from the height of an average adult eye, and once you have them you can lay out a wall of nine pieces on the floor and transfer it without guessing. Here are the measurements, including the one that saves you the second hole.

Centre height: 145 centimetres

Hang the centre of the piece about 145 centimetres from the floor, which is roughly 57 inches. Galleries and museums work to something in the 145 to 152 range, and the reason is that it puts the middle of the work at the eye level of a standing adult. Work hung at that height feels settled. Work hung at 165 feels like it is escaping.

The height is of the centre, not of the top and not of the hook. This matters most for tall pieces, because a one metre high piece centred at 145 has its top at 195, which feels high in isolation and is correct in context.

Three situations override it. Over furniture you measure from the furniture instead, as below. In a room where everybody is sitting down, a dining room or a snug, drop everything by five to ten centimetres. And if a wall has a strong architectural line, a picture rail, a dado, the top of a door frame, align to that line instead, because the eye reads the mismatch with architecture long before it reads an absolute height.

The measurement nearly everybody gets wrong

The hook does not go where the top of the frame goes. It goes lower, by the amount the hanging wire or cord drops when it is pulled taut, and that drop is often three to six centimetres on a wire and nearly zero on D rings.

So measure it. Pull the wire up tight towards the centre of the back of the frame and measure from the taut wire to the top edge of the frame. Call that the drop. Then the hook height is the height you want the top of the frame at, minus the drop.

If you prefer one formula: hook height equals 145, plus half the height of the piece, minus the drop. For a 40 centimetre tall framed print with a 4 centimetre drop, the hook goes at 145 plus 20 minus 4, which is 161 centimetres. Mark it, check it with a level if there are two hooks, and drill once.

Gaps between pieces

Five to eight centimetres between small and medium pieces. Eight to ten for large ones. Tighter than instinct suggests, and this is the single change that makes a group look composed rather than scattered.

Keep every gap identical, both horizontally and vertically. The eye is extremely good at spotting an inconsistent gap and extremely bad at noticing a consistent one, which is the whole trick. If the pieces are different sizes, the gaps stay the same and the outer edges fall where they fall.

A group of pieces that share a form can go tighter still, because the repetition carries the composition. Something like three dragonflies at three sizes reads as one object at four or five centimetres apart and as three separate objects at twelve.

Over furniture, the measurement changes

Forget the 145 rule over a sofa, a sideboard or a headboard. Leave 15 to 25 centimetres between the top of the furniture and the bottom of the piece. More than about 30 and the two stop reading as a group, which is the specific reason so much art over sofas looks stranded.

Width matters as much as height here. Aim for the art, or the group treated as one rectangle, to be about two thirds of the width of the furniture below it. Narrower than half and it looks lost; wider than the furniture and the furniture looks like it was put there afterwards.

Centre it on the furniture, not on the wall, if the two differ. A sideboard that sits off centre on its wall takes its art off centre with it, because the eye pairs the two objects and ignores the wall's midpoint.

Lining up a group: choose one axis and keep it

A group of mixed sizes needs one line that everything obeys. There are three good choices: a common top edge, a common bottom edge, or a central horizontal spine running through the middle of every piece. Pick one. The spine is the most forgiving with very different sizes, the common bottom edge reads as the most deliberate, and the common top edge works best above furniture.

Then treat the whole arrangement as a single rectangle. Find the outer boundary of the group, find the centre of that rectangle, and put that centre at 145 centimetres or at the right clearance above the furniture. Do not centre each piece individually on anything.

For a vertical pair, put the smaller piece on top and keep the same gap you would use horizontally. For a column of three, keep the gaps equal rather than increasing them down the wall. A silhouette with a strong directional pull, like a crow sitting in a ring of thorns, should face into the group rather than off the edge of it, which is a composition rule rather than a measurement but decides more than any of the numbers.

Stairs, corridors and sloped ceilings

On a staircase, the 145 rule still applies but the floor moves. Take each piece's centre to 145 centimetres above the step directly beneath it, and the group automatically follows the pitch of the stairs. The alternative, aligning the tops to the stair angle, works too and reads as more formal.

In a corridor you stand closer and look at a sharper angle, so large pieces are read in parts rather than as wholes. A row of small pieces at a consistent height and a consistent gap works better, and the gap can be slightly wider than in a room because you pass them in sequence rather than seeing them at once.

Under a sloping ceiling, drop everything. Hang relative to the lowest part of the ceiling in that bay rather than to the floor, leave at least 20 centimetres of wall above the piece, and keep the format low and wide. A tall piece under a slope always looks as though it is being squeezed, and a single horizontal object such as a cat lying along a ledge suits the space the slope leaves you.

Mock it up before you drill

Lay the whole arrangement on the floor first, at the real spacing, and look at it from a metre away. Rearranging on the floor costs nothing. Rearranging on the wall costs holes.

Then cut brown kraft paper to the exact outline of each piece, mark the hanging point on each sheet with the drop already subtracted, and tape them up with masking tape. Live with the paper for a day if the wall matters. When you are happy, drill straight through the mark on the paper and tear the paper away.

Keep a note of the final hook heights on your phone. If you ever repaint or move, the same arrangement goes back up in ten minutes instead of being rediscovered from scratch, and the numbers are also what you need in order to tell whether a new piece will fit the group you already have.

Questions people actually ask

How high should you hang wall art?
Put the centre of the piece at about 145 centimetres from the floor, which is roughly 57 inches and the eye level of a standing adult. Drop it by five to ten centimetres in a room where people are usually seated, and measure from the furniture instead when hanging above a sofa or a bed.
How far apart should pictures be in a gallery wall?
Five to eight centimetres for small and medium pieces, eight to ten for large ones, and every gap identical. Consistent spacing is what makes a mixed group read as one composition, and tighter spacing almost always looks better than wider.
How far above a sofa should art hang?
Fifteen to twenty five centimetres above the top of the sofa, and the piece or group should be about two thirds of the sofa's width. Beyond about thirty centimetres of gap the two objects stop reading as related.
Where exactly do you put the hook?
Lower than the top of the frame, by the distance the hanging wire drops when pulled taut. Measure that drop, then use this: hook height equals 145, plus half the height of the piece, minus the drop.
How do you hang pictures on a staircase?
Keep each piece's centre 145 centimetres above the step directly below it, which makes the group follow the pitch of the stairs automatically. Aligning the tops of the frames to the stair angle is the more formal alternative.
