A stairwell is the one place in a modest British house with the height for a proper piece of lighting, and it is almost always occupied by a single bulb on a short flex, hung at the height of the upstairs landing because that is where the electrician could reach.
It is also the place where getting it wrong matters most, because a dark step is a real hazard rather than an aesthetic one. Both problems have measurements.

Safety first: the stairs themselves
Before anything decorative, four rules:
- No step in shadow. Stand at the top and at the bottom in the evening. If a tread disappears, add light.
- Light the treads, not the risers. Light arriving from above and in front shows the edge of each step. Light from directly overhead flattens the flight into one surface, which is how people miss the bottom step.
- Two-way switching, top and bottom. A stair light you cannot switch off from bed will be left on.
- 2.1 metres of clearance above the highest step the fitting passes over. This is the number that decides how long your drop can be.
Working out the drop
Two measurements, and the smaller answer wins.
- From the ceiling to the highest step the fitting hangs over. Subtract 210cm. That is your absolute maximum drop.
- From the ceiling to the landing floor. Aim for the bottom of the fitting to sit roughly level with the top of the first-floor door frame, about 200cm above the landing. That is the height at which a stairwell fitting reads correctly from both floors at once.
| Ceiling to stair below | Maximum drop | Typical fitting |
|---|---|---|
| 2.6m | 50cm | Semi-flush or a short pendant |
| 3.5m | 140cm | Single long pendant, or a small chandelier |
| 4.5m | 240cm | Cluster, or a tall multi-tier chandelier |
| 5.5m and over | 340cm+ | Staggered cluster over the void |
Check the cord length before ordering, because it is the one specification people forget. The Travertine Stone Pendant comes with 170cm of cord and the Nordic Pendant with 150cm — enough for a 3.5 metre stairwell, not for a 5 metre one.
How wide the fitting should be
Use the room rule: add the stairwell's length and width in metres, then multiply by 10 for a diameter in centimetres.
A stairwell 2.5m by 2m gives 45cm. A generous double-height hall of 4m by 3m gives 70cm. Both are larger than most people choose, and in a tall space that matters: height makes any fitting read smaller, and a 30cm pendant in a 5 metre void disappears.
The Frosted 5 Glass Ball Chandelier is 67cm across and 34cm deep, which suits a hall of that size; the Modern Crystal Chandelier at 60 by 74cm has the vertical presence a tall void wants. For something quieter, the Ring Chandelier at 65cm reads as a line rather than an object.
Which type suits which stairwell
- A single long pendant — best over a stairwell you look down into from a landing. Simple, and the drop does the work. The Travertine Pendant with 180cm of cord, or the Luxury Nordic Pendant at 150cm.
- A multi-tier chandelier — for a genuinely double-height hall where you want the piece seen from the front door. The 12-Light Two-Tier Wrought Iron at 105cm across is sized for it.
- A staggered cluster — three or five pendants at different heights over the void. It fills vertical space better than any single object, and it is forgiving: nothing has to be exactly level. The Rattan Cluster and the Ribbed Glass Round Cluster do it in one fixing.
- A semi-flush — the right answer in a 2.6m stairwell, where a pendant would be ducked under. The Sputnik Chandelier or the Crystal Flush Chandelier.
One composition rule worth following: centre the fitting in the window of the stairwell as seen from below, not on the plan. A stairwell is looked at from underneath far more often than it is looked at on a drawing. The full set of clearances is in how high should a pendant light hang, and the range is in chandeliers and pendant lights.
A straight flight against a wall
Most British stairs are not a double-height void at all: they are a straight flight with a wall on one side and a ceiling 2.3 metres above the treads. There is no room for a pendant, and no need for one.
Wall lights are the answer:
- 150cm above the pitch line — the imaginary slope joining the nose of each step — so the height steps up with the stairs.
- One fitting every three or four steps.
- Shallow. Under 12cm of projection, because people pass within inches of them. The Nordic Corridor Sconce projects 5cm; the Retro Staircase Sconce is the period version.
All the wall-light heights in one table are in how high should wall lights be.
The landing
The landing does not need a second statement piece. It needs enough light to stop the top of the stairs being a dark edge, and no more.
A flush or semi-flush fitting is right: the Glass LED Flush Mount or the Nordic Glass Ceiling Light. If the landing is wide enough for furniture, a lamp on a console at waist height does more for the feel of the space than anything on the ceiling — the same principle as in hallway lighting for low ceilings.
Changing the bulb, honestly
Nobody thinks about this until the first bulb goes, three metres above a staircase where no ladder will stand.
Three practical answers:
- Choose long-life LED. A quality LED at 15,000 to 25,000 hours will run for years in a stairwell, which is used in short bursts.
- Buy a fitting with few bulbs rather than many. A five-arm chandelier over a void means five awkward changes.
- Plan the access before you buy. If a stair platform or a tower is the only way to reach it, decide that in advance rather than discovering it in the dark. An integrated LED fitting with no replaceable bulb is a reasonable choice in a genuinely unreachable position.
Bulbs and switching
2700K, matching the hall below, so the two spaces read as one. 800 to 1,500 lumens in total is ample: a stairwell is passed through, not occupied, and a very bright fitting at eye level from the landing is unpleasant.
Two-way switching is not optional. If the stairwell fitting can only be switched from downstairs, it will be left on all night or the stairs will be climbed in the dark. Neither is acceptable.
Where the fitting is visible from the landing at close range, choose a shade that conceals the bulb — fabric, opal glass, rattan — rather than clear glass, which glares at that distance. The reasoning is in choosing colour temperature.
Five mistakes worth avoiding
- A drop that breaks the 2.1 metre clearance. Measure from the highest step, not the landing.
- A fitting that is too small. Height shrinks everything: use the room rule and then go up a size.
- Ordering without checking the cord length. Most pendants ship with 100 to 180cm, which is not enough for a tall void.
- Forgetting how you will change the bulb. Decide before, not after.
- One-way switching. The single most annoying fault in any house.
In short
- Clearance: 2.1m above the highest step, always.
- Ideal height: bottom of the fitting level with the first-floor door head, about 200cm above the landing.
- Diameter: (length m + width m) x 10 in cm, then go one size up.
- Straight flight: wall lights at 150cm above the pitch line, every 3 – 4 steps.
- Output: 800 – 1,500 lumens, 2700K.
- Two-way switching, and a plan for changing the bulb.
Common questions
How low should a stairwell light hang ?
No lower than 2.1 metres above the highest step it passes over. Within that limit, aim for the bottom of the fitting to sit level with the top of the first-floor door frame, roughly 200cm above the landing, so it reads correctly from both floors.
What size light for a stairwell ?
Add the stairwell's length and width in metres and multiply by 10 for a diameter in centimetres — a 2.5m by 2m space suggests about 45cm. Then consider going one size larger, because height makes any fitting look smaller.
How do I light a straight staircase with a low ceiling ?
With wall lights rather than a pendant: mount them 150cm above the pitch line, one every three or four steps, and choose a design projecting less than 12cm so nobody catches a shoulder.
How many pendants should hang in a stairwell ?
One long pendant suits most stairwells. In a genuinely double-height void, a staggered cluster of three or five at different heights fills the vertical space better than a single fitting and is more forgiving to install.
How do you change a bulb in a high stairwell ?
Plan it before you buy. Choose long-life LED bulbs, prefer a fitting with few bulbs rather than many, and where access needs a stair platform or tower, consider an integrated LED fitting with no replaceable bulb.
Do stair lights need two-way switches ?
Yes, at the top and the bottom. A stair light that can only be switched from one end is either left on all night or means climbing the stairs in the dark.
What colour temperature for a stairwell ?
2700K, matching the hallway below so the two spaces read as one, at 800 to 1,500 lumens in total. Choose a shade that conceals the bulb, since the fitting is often seen at close range from the landing.
Measure from the step, not the floor
Every stairwell mistake starts with measuring from the landing. Measure from the highest step the fitting hangs over, subtract 210cm, and the rest is a choice rather than a risk.
