We offer a wide range of chandeliers varying in size, finish, and style. Choosing the right size is not always straightforward — a fixture that's too small gets lost in the room, while one that's too large overwhelms the space. This guide gives you the exact formulas interior designers use to get it right every time.

1. Chandelier diameter — the room size formula

The most widely used rule in interior design: add your room's length and width together in feet. The result in inches is a reliable starting diameter for your chandelier.

For rectangular rooms this works for the longest span. For square rooms the formula applies directly. If the result feels too large, go 10–15% smaller — this is a starting point, not a fixed rule.

2. Chandelier height — the ceiling formula

Fixture height (from canopy to lowest point) should scale with ceiling height. This applies to pendant-style chandeliers, not flush-mount ceiling lights.

3. Hanging height — clearance rules

Hanging height is the distance from the floor (or tabletop) to the bottom of the fixture — separate from the fixture height itself.

4. Dining room & kitchen islands

Size the chandelier based on the furniture itself — not just the room. The chandelier width or diameter should be between half and two-thirds of the table width.

For very long tables (over 72 inches), a linear chandelier distributes light evenly and mirrors the table geometry.

5. Staircases & two-storey foyers

Staircase chandeliers are seen from two levels simultaneously, so both perspectives matter when choosing size and hanging height.

• Upper-floor reference: Hang the chandelier slightly below the top of the staircase so the top sits at eye level from the second floor.
• Architectural centring: Centre independently on a skylight or arched window above the door for best visual impact from outside.

6. Long hallways

For hallways, chandelier size is determined by width rather than overall room area.

For multiple chandeliers in a long hallway: centre each fixture across the width, space them 8–10 feet apart, and maintain at least 7.5 feet of floor clearance throughout.
