Chandelier Size Calculator

Written by Rick Kovac, COO of Golden Lighting

The takeaway: Enter your room, ceiling and table, and this calculator applies the Golden Scale Method. You get a chandelier diameter, a fixture height and a hanging height in one step.

Your room

Room length (ft) Room width (ft) Ceiling height (ft)

Where it hangs Fixture style

Your table

Table shape Table length (in) Table width (in)

Enter your room length and width to see your size.

How the calculator works

It runs the three checks from The Golden Scale Method:

Room formula: room length + width in feet = the fixture's minimum diameter in inches.
Table ratio: over a rectangular table, the fixture spans 1/2 to 2/3 of the table's width, with its edge about 6 in inside the table edge. When the room and the table disagree, the table wins.
Scale check: airy designs can size up a step; dense or ornate ones should size down a step.

Then it adds height. The fixture should be 2.5 to 3 in tall per foot of ceiling. Hang it 30 to 36 in above the table, or at least 7 ft above the floor where people walk.

Every number here comes from Golden Lighting's design rulebook. The rulebook is built on published lighting standards, including the IES/ALA recommended practice for residential lighting (ANSI/IES RP-11-26) and the National Electrical Code, plus the judgment of professional lighting designers.
