A wall sconce goes at 60 to 66 inches from the finished floor to the centre of the fixture. That is roughly eye level for a standing adult, and it is the height that works in a hallway, beside a mirror and along a stair wall. The word that does the work in that sentence is centre, and getting it wrong is why so many sconces sit too high.
People measure to the mounting box, or to the top of the backplate, or to the bottom of the shade. The number refers to the vertical centre of the fixture, and on a tall sconce those two points can be six inches apart.
Numbers to keep in mind
- General wall sconce: 60 to 66 inches floor to centre of fixture.
- Flanking a bathroom mirror: 60 to 66 inches, and 36 to 40 inches apart.
- Along a hallway: 60 to 70 inches, spaced 6 to 8 feet apart.
- Beside a bed: 50 to 60 inches, measured so the light falls on a book rather than in your eyes.
- Projection from the wall in a corridor: keep it under 4 inches at head height, or move it up.
- On a stair wall, measure from the nose of the tread directly below, not from the landing floor.
Centre, not box, not bottom
Take the fixture's overall height and halve it. An 18 inch tall sconce hung at 63 inches to centre has its top at 72 inches and its bottom at 54. Those two numbers are what you actually see, and they are what tell you whether the fixture works on that wall.
The mounting box is usually not at the centre of the fixture. On a bell sconce or an uplight the box sits low; on a downlight it sits high. So the box height and the centre height are different numbers, and the one on the fixture's instruction sheet is the box.
The practical method: cut a paper rectangle the size of the fixture, tape it to the wall with its centre at 63 inches, and look at it. Adjust, then measure to the box from where the paper ends up.
By location
| Location | Height, floor to centre | The governing constraint |
|---|---|---|
| Beside a bathroom mirror | 60 to 66 in | Eye level of the person at the basin |
| Hallway | 60 to 70 in | Head clearance and projection |
| Stairs | 60 to 66 in above the tread nose | Consistency as you climb |
| Beside a bed | 50 to 60 in | Light on the page, not in the eyes |
| Flanking a fireplace | 60 to 66 in | Relationship to the mantel, not the floor |
| Beside a front door | 66 to 72 in | Above the door head, and matched on both sides |
The stair case, which is the one that goes wrong
On a staircase, every sconce is at a different floor height, so measuring from the floor produces a row of lights that steps unevenly.
Measure from the nose of the tread directly below each fixture, and use the same number every time. The sconces then climb parallel to the stair, which is what the eye expects. It takes longer to set out and it is the difference between a staircase that looks designed and one that looks approximate.
Spacing along a wall
Six to eight feet between sconces in a corridor. Closer than six feet reads as busy and starts to look like a hotel; further than eight leaves dark stretches between pools of light.
Set the outer sconces in from the ends of the run first, then divide the remaining distance equally, exactly as you would with pendants over an island. Starting from one end and working along at a fixed spacing leaves an awkward remainder at the far end.
Projection, the thing nobody measures
In a corridor, the number that matters as much as height is how far the fixture sticks out. A sconce projecting six inches at 63 inches high is at shoulder height in a narrow hallway, and people will catch it.
Under four inches of projection is comfortable at eye level. Anything more should either move up above head height, or go on a wall people do not brush past. Flush-backed sconces and half-shades exist precisely for tight corridors.
What the sconce is relating to
Height is a floor measurement, but a sconce almost never relates to the floor. It relates to whatever it is beside, and where the two disagree, the object wins.
Beside a mirror, align the sconce centre with the height of a face, which is usually a little below the mirror's own centre. Flanking a fireplace, relate the sconce to the mantel: a consistent gap above the mantel shelf reads better than a consistent height off the floor, particularly if the floor is not level. Beside a doorway, relate it to the head of the door.
Over a piece of art, the sconce should sit above the frame rather than beside it, and its own height then follows the art. That is a case where the 60 to 66 inch rule is simply the wrong tool.
The general principle: use 63 inches as the starting point, then look at what else is on the wall and let that move it. A sconce that is exactly right by the tape and visibly wrong against the mirror beside it is still wrong.
Glass, and why it matters more on a sconce
A sconce is the one fixture type mounted at eye level, which means the lamp inside it is in your field of view whenever you are in the room. Clear glass and an exposed filament at 63 inches is glare.
Frosted glass, an opaque shade, or a fixture that directs light up and down rather than sideways all solve it. This is why so many bathroom sconces use frosted glass, and it is a functional decision rather than a stylistic one.
Sconces in this catalogue
The wall range is in Wall Sconces, and the frosted-glass family sits in Kohler Bancroft.
- Kohler K-22546-SC01-BZL Damask 11in 1-Light Water Globe Sconce, oil-rubbed bronze. Eleven inches tall, so it sits neatly within a 60 to 66 inch centre.
- Kohler K-32282-SC02-BLL Hauksbee 2-Light Bell Wall Sconce, matte black. Bell shades direct light down, which suits a corridor.
- Kohler K-32281-SC01-BLL Hauksbee 1-Light Bell Wall Sconce, matte black. The single-lamp version, for a narrower wall.
- Kohler K-11423-BZL Bancroft 3-Light Wall Sconce, frosted glass, oil-rubbed bronze. Classified as bathroom lighting, and frosted glass is why it works at eye level.
- Kohler K-11422-CPL Bancroft 15in 2-Light Wall Sconce, frosted glass, polished chrome.
Note that the Bancroft fixtures sit in Vanity and Bathroom Lighting rather than in the wall sconce collection, because Kohler classifies them as bathroom fixtures. They mount and measure exactly the same way.
Frequently asked questions
How high should a wall sconce be?
60 to 66 inches from the finished floor to the vertical centre of the fixture. Measure to the centre, not to the mounting box or the bottom of the shade.
How far apart should sconces be in a hallway?
Six to eight feet between fixtures. Set the outer two in from the ends of the run first, then divide the remaining space equally so the spacing is even.
How high should sconces be beside a bathroom mirror?
60 to 66 inches to the centre, and 36 to 40 inches apart, which puts the light either side of a face at the basin rather than above it.
What height for sconces on a staircase?
60 to 66 inches measured from the nose of the tread directly beneath each fixture, not from the floor below. That keeps the row parallel to the stair.
