Hallway and Stairwell Lighting: Spacing, Heights and the Mistakes That Make a Corridor Feel Like a Corridor

Hallways and stairwells are the spaces people light last and think about least, which is a shame, because they are the parts of the house everyone walks through several times a day and the first thing a visitor sees. A well lit hallway makes a small house feel generous. A badly lit one makes a large house feel like a hotel corridor.

The good news is that it comes down to a handful of numbers.

Wall lights or ceiling lights

Both, ideally, on separate switches. Ceiling lights give you the bright, practical light for finding keys and seeing the stairs. Wall lights give you the low, warm light for the evening, and they light the walls, which is what makes a narrow space feel wider.

If you can only have one, and the hallway is under about 1.2m wide, go with ceiling lights and put the money into good ones. Wall lights in a very narrow hall get caught by shoulders and bags.

Above 1.2m wide, wall lights are the better investment. They do more for how the space feels than any ceiling fitting can.

Mounting height

In a hallway, 1.6m to 1.7m from the finished floor to the centre of the fitting. That puts the light just above eye level for most adults, so it lights the face without glaring into it, and high enough that nobody catches it with a shoulder.

If the ceiling is low, under 2.3m, come down slightly to 1.5m so the fitting is not crammed against the top of the wall. If it is high, over 2.7m, you can go up to 1.8m.

Spacing along a corridor

2m to 2.5m apart, and the same distance from each end wall. Closer than 2m and it starts to look like a runway. Further than 3m and the pools of light stop joining up.

Count from the length of the hall. A 5m corridor takes two fittings, one at roughly 1.25m from each end. A 7m corridor takes three. Odd numbers look better than even ones if the hallway has a focal point at the far end, because one fitting lands centrally.

Where there are doors, position the lights between them rather than beside them. A wall light next to a door frame looks cramped and gets hit by the door.

Staircases

This is where most schemes go wrong, and it is one measurement.

Measure from the nose of the tread, not from the floor. On a staircase the floor is a slope. If you fix every wall light at the same height from a single reference point, they will not follow the stairs and the result looks like a mistake. Instead, measure 1.6m to 1.7m vertically from the front edge of the tread directly below each fitting. The lights then climb the wall at the same angle as the stairs.

Spacing on a straight flight: every three to five treads, depending on tread depth, so roughly every 1m to 1.5m of horizontal run. A typical 13-tread domestic flight wants three fittings: one near the bottom, one in the middle, one near the top.

On a half landing, one fitting on the landing wall, centred, at the standard 1.6m to 1.7m. It does two jobs: it lights the turn, and it marks the change of direction.

The landing

Landings are where lighting schemes give up. They are often a leftover shape with several doors and no obvious wall, and they end up with one ceiling light in the middle.

Two things fix it. First, treat the landing as its own room with its own wall light, on the longest uninterrupted wall, at the standard height. Second, put it on the same switch as the top stair light so the two read as one scheme.

If there is a window on the landing, put the wall light on the wall opposite it. The window lights the space by day, the wall light by night, and neither fights the other.

Switching

Hallway and stair lights need two way switching as a minimum: a switch at the bottom of the stairs and another at the top, so the lights work from either end. On a long hallway, add an intermediate switch by the front door. This is basic and every electrician does it, but confirm it is in the plan before the walls are closed.

Worth considering: a PIR sensor for the ceiling lights, so the bright light comes on when someone walks in and off again after, and the wall lights on a separate switch or a timer for the evening.

Which fittings

Hallway wall lights get seen in a row, so they need to be calm. Fussy fittings repeated six times look busy. The classic choices are plaster wall lights painted to match the wall, or a simple stone or glass fitting in a consistent finish.

For a hallway that is a feature, the front hall of a period house, a wide entrance, a stairwell with a double height void, alabaster is worth the extra. The stone glows rather than shines, so a row of them reads as a series of soft warm panels rather than a line of bulbs, and the effect at the front door is the first impression of the whole house. Our Colonna at 35cm is the one we suggest most for corridors, from £189.00 including VAT, and the Pillar at 65cm for a stairwell that has the height to carry it. We compare the two materials properly in plaster wall lights vs alabaster.

Colour temperature

Warm, 2700K to 3000K, on the wall lights. The ceiling lights can go slightly cooler, 3000K to 3500K, if they are the practical layer. Do not mix a warm wall light with a cool ceiling light on the same switch; the difference is obvious and looks accidental.

The mistakes, briefly

Fixing stair lights at the same height from the floor. Measure from the tread.

Spacing by the wall rather than by the length. Work out the number first, then the positions.

Wall lights beside door frames. Put them between doors.

One switch at one end. Two way as a minimum.

Forgetting the landing. It is a room. Light it like one.

Fittings that are interesting individually and exhausting in a row. Choose the boring option and repeat it.

Common questions

How high should hallway wall lights be mounted?

1.6m to 1.7m from the finished floor to the centre of the fitting. That sits just above eye level, so the light reaches the face without glaring, and nobody catches it with a shoulder. Drop to 1.5m under a low ceiling below 2.3m, and go up to 1.8m under a ceiling over 2.7m.

How far apart should wall lights be in a hallway?

2m to 2.5m apart, and the same distance in from each end wall. Closer than 2m looks like a runway; further than 3m the pools of light stop joining up. A 5m corridor takes two fittings and a 7m corridor takes three. Position them between doors rather than beside door frames.

How do you position wall lights on a staircase?

Measure 1.6m to 1.7m vertically from the nose of the tread directly below each fitting, not from a single floor level. The lights then climb the wall at the same angle as the stairs. Fixing every light at the same height from one reference point is the most common stairwell mistake.

How many wall lights does a staircase need?

One every three to five treads, so roughly every 1m to 1.5m of horizontal run. A typical 13 tread domestic flight wants three: one near the bottom, one in the middle and one near the top, plus one centred on the landing wall at a half landing.

Do hallway and stair lights need two way switching?

Yes, as a minimum: one switch at the bottom of the stairs and another at the top so the lights work from either end. On a long hallway add an intermediate switch by the front door. Confirm it is in the plan before the walls are closed.

Where to start

Our alabaster wall lights run from £140.00 including VAT, and most are available in more than one size for mixing a corridor with a stairwell. For projects with a run of six or more we can quote the set and, if the rest of the house is a particular finish, produce them in matte or brushed antique brass. Call 0330 133 6617 with the hallway length and the number of stairs and we will work out the count.
