What Size Chandelier Do I Need? The Room & Table Rules
Quick answer: diameter in inches = room length + width in feet (a 12×14 room takes 26 in). Over a dining table, use two-thirds of the table width and hang the bottom 30–36 in above the tabletop.
The room rule
For open spaces with no table beneath — foyers, stair landings, living areas — add the room's length and width in feet; the sum is the chandelier diameter in inches. A 12×14 room: 12 + 14 = a 26-in chandelier. A 16×20 great room: a 36-in fixture.
The table rule
When the chandelier hangs over a dining table, size to the table, not the room: the diameter should be about two-thirds of the table width.
| Table width | Chandelier diameter |
|---|---|
| 42 in | 28 in |
| 48 in | 32 in |
| 54 in | 36 in |
| 60 in | 40 in |
| 72 in | 48 in |
When the two rules disagree, the table rule wins — a fixture sized to the room looks enormous over a small table.
Hanging height
Over a table, hang the bottom of the fixture 30–36 in above the tabletop. In open areas, keep it 7 ft above the floor so nobody walks into it. On an 8-ft ceiling a typical chain runs 2–3 ft; add 3 in of drop for every foot of ceiling over 8 ft. Buy the chain 6–12 in longer than you think — shortening it is easy, stretching it isn't.
Foyers, islands & special spots
- 2-story foyer: bottom of the fixture 7 ft above the floor, centered in the door sightline; let a long chain reach rather than buying taller.
- Kitchen island: one mini-pendant or small fixture per 2 ft of island, or two pendants over a 6-ft island.
- Bedroom: size to the room rule, hang so the bottom clears a standing adult — 7 ft minimum.
- Close to windows: keep 6–12 in from the glass and clear a fully open door swing by 6+ in.
Sizing mistakes
- Sizing a table chandelier to the room — the fixture overwhelms the table.
- Hanging too high or too low — 30–36 in over the table is the comfort zone.
- Buying a chain too short — vaulted ceilings eat chain fast.
- Ignoring walk clearance — keep 36+ in from walls and paths.
- One giant fixture over a long table — two smaller pendants light a 72-in table better.
