Guide

Size, base and colour

  1. 1

    Chandelier size

    A common rule of thumb: the room length plus width in feet gives the diameter in inches. A 12 × 14 ft dining room takes about 26 in.

  2. 2

    Bulb base

    E26 is the standard medium base; E12 candelabra is the small base on many chandeliers and sconces.

  3. 3

    Colour temperature

    2700K is the warm light of a classic bulb, 3000K a little whiter, 4000K neutral and 5000K daylight.
