There is a number, and once you know it you see it everywhere. Fifty seven inches, or about a hundred and forty five centimetres, measured from the floor to the centre of the picture. Galleries hang to it, decorators quote it, and a great deal of hanging advice is really just this one figure with variations.

- The gallery rule: 57 inches, about 145 cm, from the floor to the centre of the picture.
- Measure to the centre, then allow for the wire when you place the hook.
- At home, seated eye level and the furniture matter more than the rule.
The justification given for it is that fifty seven inches is roughly the average human sightline. Hang the middle of the work there and the middle of the work meets the eye of an average adult standing in front of it.
The fifty seven is to the centre of the artwork, not to the hook.
The obvious question is average of whom, and the honest answer is that it is an approximation carrying a lot of variation inside it. Adult eye level differs by a good deal more than the tolerances people fuss over when levelling a frame. What the number is really doing in a gallery is something slightly different from serving any individual visitor. It is producing consistency. When every work in a long room is centred at the same height, the eye travels along a level line and the hang disappears, leaving the pictures. That is worth a great deal in a museum and it is worth almost nothing in a hallway.
The mistake almost everybody makes with the rule is mechanical. The fifty seven is to the centre of the artwork, not to the hook. To find the hook you take the height from the centre of the picture up to its top edge, then subtract however far the wire drops when it is pulled taut, and it is the second measurement people forget. A frame with a slack wire hangs noticeably lower than the arithmetic promises, which is why so many carefully measured pictures end up a few centimetres out.
The standard adjustments are sensible and they all quietly admit the rule's limits. With a high ceiling, most people go up to fifty eight or sixty inches so the picture does not look stranded in the lower half of the wall. Above a sofa or a sideboard, the furniture becomes the reference point rather than the floor, because the eye reads the picture and the furniture as one object. With a group of pictures, you treat the whole arrangement as a single work and centre that, which means individual frames land wherever the composition needs them.
Underneath the adjustments there is a bigger assumption, which is that the viewer is standing. In a gallery they are, and they are moving, and they will be in front of any given work for well under a minute. Almost none of that is true at home. In a dining room everybody is seated for two hours. Beside a bed people are lying down. In a room with a low sofa the eye level of a seated adult can be thirty or forty centimetres below the standing figure the rule was built for, and a picture hung to gallery height in that room is technically correct and slightly wrong.
What the height is really deciding is how much of the room the picture is in charge of. Hung high, it becomes ceremonial and a little remote, which is the register of a portrait over a fireplace and of most official buildings. Hung low, closer to the furniture, it joins the room and behaves like an object among other objects rather than an announcement. A lot of people have stopped hanging small pictures at all and lean them on shelves and mantelpieces, which is the extreme version of the same instinct, and it works for exactly the same reason.
The size question sits underneath all of this and is the one worth settling first. A picture that is too small for its wall cannot be rescued by hanging it at the perfect height, and going up a size generally does more for a room than any amount of measuring. The framed prints come in a range from small pieces that suit a shelf or a narrow stretch of wall to sizes that can hold a room on their own, and the honest way to choose is to mark the outline on the wall with masking tape and live with it for a day before deciding.

Knowing the rule is genuinely useful, and mostly because it tells you what you are departing from. Fifty seven inches is a convention invented for a building where strangers walk past hundreds of works in an hour. A home is the opposite of that. The same picture will be seen by the same few people several thousand times, from a sofa, from a doorway, half noticed on the way to the kitchen. Where a photograph wants to sit in that kind of room is a question the gallery convention was never trying to answer.
