How low can a pendant light hang in a hallway?
210 cm (83 in) from the floor to the bottom of the light
In a hallway, keep the bottom of a pendant at least 210 cm (83 in) from the floor, so that nobody walks into it. Under a 2.4 m (7 ft 10 in) ceiling that leaves 30 cm (12 in) for the whole fitting, so a shade 30 cm (12 in) tall has to sit against the ceiling. One UK lighting shop allows 200 cm (79 in) as the least.
A hall is the one place in a house where everyone walks directly under the light, often carrying something. The clearance is for the tallest person who uses the house, with an arm raised to pull on a coat.
Under a standard ceiling that rules out most hanging shades. A flush or semi-flush fitting gives the same light without the risk. Save the long pendant for a stairwell or a double-height hall, where the drop can run down past the landing.

The working
- Keep 210 cm clear from the floor to the bottom of the light.
- Drop = 240 − 210 − 30 (fitting) = 0 cm.
One UK lighting shop gives 200 cm as the least; we use 210 cm, The Lighting Centre's figure.
The rule, and its source
Headroom under a hanging light
Where people walk under a light, keep its bottom at least 2.1 m from the floor. Jim Lawrence gives at least 2 m (7 ft) in sitting rooms, bedrooms and halls.

Other ceiling heights
How much height each ceiling leaves for the whole fitting, and for the cord above a shade 30 cm (12 in) tall.
| Ceiling | Room for the fitting | Cord above the shade |
|---|---|---|
| 2.3 m (7 ft 7 in) | 20 cm (8 in) | — |
| 2.4 m (7 ft 10 in) this page | 30 cm (12 in) | 0 cm (0 in) |
| 2.5 m (8 ft 2 in) | 40 cm (16 in) | 10 cm (4 in) |
| 2.7 m (8 ft 10 in) | 60 cm (24 in) | 30 cm (12 in) |
| 3 m (9 ft 10 in) | 90 cm (35 in) | 60 cm (24 in) |

Your sizes will differ. The pendant light height and size calculator opens with these numbers filled in: change any of them and the answer, the working and the drawing follow.
Editorial notes
Worked out by the Snuug team on 12 November 2026 with the same code as the pendant light height and size calculator, so the two cannot disagree. Every rule cites its source, with the date we last checked it. A rule designers use is a convention, not a study.
