Chandelier Buying Guide
A large chandelier is difficult to change after it is built, so the questions are worth settling in a fixed order. This page is that order, and it points to the guide that covers each step in detail. Nothing here is a catalogue figure; where a number is needed, it is on the guide it belongs to.
1. Start from the room, not the fixture
The first decision is not a design decision, it is a constraint: how much vertical room does the fixture have, and what is above it. An 8–9 ft ceiling takes a standard drop. Below about 8 ft, the answer is usually a flush or semi-flush fitting, or a chain shortened so the fixture clears head height. In a two-storey room the ceiling height stops being a constraint and becomes the thing the fixture is sized to.
What decides the rest is the surface the fixture is seen against — a table, a stairwell void, a foyer floor — and the sightline from the main door. Those two facts narrow every later choice more than a preferred style does.

2. Set the diameter before the design
Three working conventions cover most rooms:
- Whole room: add the room's length and width in feet and read the total as a diameter in inches.
- Over a table: roughly one third of the table's width.
- Double-height void: roughly one third of the width of the space, measured at its widest point.
They are rules of thumb, and they assume an 8–9 ft ceiling. Below that, or over a table rather than a room centre, size from the surface directly under the fixture instead.

3. Set the drop, then confirm the clearance
Diameter and drop are separate decisions and are usually set on site against the real measurement. Over a table, a widely used convention is 75–85 cm (30 to 33 in) between the table surface and the lowest point of the fixture. In a corridor or foyer, allow at least 6 ft 7 in (2.0 m) of clear passage beneath it. Where headroom is tight, a shorter drop is the answer rather than a smaller fixture.

4. Decide how it hangs
Chain, wire suspension or flush mounting. Chain reads as a deliberate design element and is simpler to shorten on site; wire is visually quieter and suits a room where the ceiling detail is the feature; flush mounting keeps headroom clear but cannot tilt, so it is not the answer on a sloped ceiling. The suspension choice also fixes the ceiling detail your electrician will work to.

5. Decide the light
Light colour is chosen by how the room is used, not by the fixture. Warm 3000K suits living and dining rooms; 4000K is cooler and is the usual choice over a work surface or in a commercial lobby. Dimming is arranged against the dimming system the project already has rather than selected as a catalogue value, so it is worth deciding this alongside the electrical plan rather than after the fixture arrives.
6. Decide the material and the finish
Crystal and steel are the core build: a crystal or glass element on a stainless steel or electroplated frame. K9 crystal is cut to refract sharply and reads jewel-like; alabaster is naturally translucent and diffuses light into a softer, stone-like glow. Swapping between them changes the character of a fixture more than most other options do. Metal finish is a separate choice again, and can be matched to a reference.

7. Confirm certification, lead time and budget — in that order
Certification and lead time are project facts, not preferences: a commercial or inspected installation usually needs the certificate paperwork alongside the fixture, and most of the range is built to order, so the calendar starts when the specification is confirmed rather than when the order is placed. Budget follows size and configuration, so it is the last of the three to settle, not the first.
What to have ready before you ask for a quote
A quotation is answered against a specification, so these four facts are what make the reply useful rather than a range:
- The room or void dimensions — floor to ceiling at the fixing point, and the width at the widest point.
- A photograph or drawing showing the ceiling and, where relevant, the surface below it.
- The mounting surface: what the fixture will hang from.
- Quantity and target date.
Trade and project enquiries are handled through the designer & trade programme; the commissioning route itself is on the customization process page.

Where this guide stops
- The sizing conventions are not code. They are trade rules of thumb. Local building code and a structural engineer's assessment govern.
- A quotation is written, not quoted from a range. Trade and project work is priced against a specification; we do not publish trade pricing.
- We do not publish named project references. There is no case-study page here. If you need to see comparable work, ask us directly.
- We supply the fixture, not the site work. The ceiling fixing point and the electrical connection are carried out by a qualified electrician. What we supply is the fixture, the fixing and load information, and the installation sequence.
