How to Size a Chandelier: The Complete Guide

← All sizing guides

A chandelier that's too small gets swallowed by the room; one that's too big overwhelms it. The good news: designers size chandeliers with a few simple formulas, and they work in almost every home.

Here's exactly how to get the diameter, hanging height, and scale right — for dining rooms, foyers, bedrooms, and everything in between.

Find your chandelier size

A starting point from the formulas below. Between two sizes, most designers go up.

The formula

Room size to diameter

Length + width, in feet
= diameter, in inches

A 12′ × 14′ living room → 12 + 14 = 26 → a chandelier roughly 26″ across.

The Roundout 9 Light Chandelier measures exactly 26″ across, if you want to see what that looks like in the room.

This is a starting point, not a law. Rooms with tall ceilings, bold architecture, or minimal furniture can handle going a size up. When in doubt between two sizes, most designers choose the larger — an ambitious chandelier reads as intentional; an undersized one reads as a mistake.

Over the table

Sizing over a dining table

Over a table, the table — not the room — sets the size. Two rules:

  • Diameter: one-half to two-thirds the width of the table. For a 42″ wide table, that's a fixture roughly 21″–28″ across.
  • Length (for linear chandeliers): one-third to one-half the table's length, and never longer than the table minus 12″ on each end. A 72″ table pairs well with a 24″–36″ linear fixture.

Longer tables scale up from there — the Averitt Linear Chandelier runs 42″, which sits in the one-third-to-one-half band for tables from about 84″ to 126″.

Hanging height

How high to hang it

  • Over a dining table: 30″–36″ from the tabletop to the bottom of the fixture with an 8-foot ceiling. Add about 3″ of height for every foot of ceiling above 8 feet.
  • In open rooms and hallways: keep at least 7 feet of clearance from the floor to the fixture's lowest point — 7′6″ is more comfortable where people pass directly underneath.
  • In a two-story foyer: if there's a window above the front door, center the chandelier so it's visible through the window from outside. As a rule, the bottom of the fixture should hang no lower than the second-floor line.
Entries and foyers

Foyer sizing

The length-plus-width formula works here too, but ceiling height matters more. For two-story foyers, choose a multi-tier or elongated design — a fixture 2 to 3 feet tall or more — so it holds its own in the vertical space.

The Skye Medium Six Light Multi Tier Chandelier is a good example of the proportion: 24″ wide but 58″ tall, so it fills the drop without crowding the entry. In a small entry, a flush or semi-flush fixture may serve better than a chandelier — something like the Harper Medium Semi-Flush Mount at 14.5″ wide; see the full semi-flush collection.

Common questions

Frequently asked questions

Can a chandelier be too big?

Yes, but it's rarer than too small. If the fixture's diameter approaches the width of your table, or people risk brushing it, size down.

What if my table is round?

Use one-half to two-thirds of the table's diameter, and favor round or drum fixtures over linear ones.

Do sputnik and open-frame designs follow the same rules?

Yes — measure their full diameter arm-tip to arm-tip. Their airy structure means you can comfortably go to the top of the size range.
