A 20 ft (6.1 m) or 25 ft (7.6 m) ceiling is not a tall room with a bigger light fitting in it. The fixture has to be read from across the space, the suspension has to reach the people underneath, and the light has to arrive at floor level. Most mistakes at this height are made with the drop.
The proportions, in feet
A useful scaffold for tall spaces:
- Diameter: aim for roughly one third of the width of the space or opening the fixture hangs in. In a 12 ft wide foyer, that points to about 4 ft (roughly 120 cm) as a starting diameter.
- Bottom of the fixture: no lower than about 7 ft above the floor you stand on, and in a two-storey foyer usually higher, so that the sightline from the door meets the fixture in the middle of the void.
- Top of the fixture: well below the ceiling — a large fixture crowded against a 25 ft ceiling reads as smaller than it is, and it also makes maintenance awkward.
- Resulting drop: on a 20 ft ceiling with the fixture bottom at 8–9 ft and a 5 ft tall composition, the suspension runs roughly 6–7 ft. On 25 ft ceilings, expect 8–11 ft of suspension, or a taller fixture body with a shorter chain.
Those figures are arithmetic, not rules — the binding constraint is always head clearance at every level and the sightline from the entrance.
At this height, the fixture becomes a composition
Above about 6 m, a single-body chandelier runs out of proportion. The solutions that work are compositional:
- Extended bodies — a taller silhouette with more tiers, so the fixture occupies the vertical space rather than being suspended through it. See high ceiling chandeliers.
- Tiered compositions — rings or tiers at intervals, which carry the eye up the void and let you control the visual mass independently of the diameter.
- Cascades — long falling elements for stairwells and voids where the fixture is seen from the side. See staircase chandeliers.
- Multi-point suspension — on very large or 8 m+ fixtures, the load is often distributed across several fixing points rather than one, which changes the drawing set.
Suspension: adjustable, and sized for the room
A chain cut to a guessed length is one of the most common problems we are asked to solve. For any ceiling above about 5 m, specify an adjustable suspension with a documented minimum and maximum, and size the canopy for the actual fixing point — including any coffered or recessed ceiling detail. On fixtures where the drop is critical, we set it in the drawing set and confirm it against your section drawing before production.
Lighting the lower level
A 25 ft ceiling is far from the people in the room. Whatever the fixture's output, the space also needs light at the lower level — from wall lights, floor lamps or architectural lighting that is not part of the chandelier. A chandelier asked to light a whole double-height room from 7 m will either be too dim at floor level or glaring from underneath. Plan the two layers together: the fixture as the visible source, and a lower layer for the light you actually live in.
What to send us
- Ceiling height at the fixing point, and floor-to-floor if there is a landing.
- Width of the space or opening.
- A photograph of the ceiling, and a section drawing if one exists.
- Voltage, dimming and the installation date.
Send those and we will come back with diameters that suit the space and the drop calculated against your ceiling height. The starting points are in oversized chandeliers and extra large chandeliers, and the process is on the order process page.
