Ceiling medallion size guide (in inches)
Quick answer
A quick rule for ceiling medallion size: add the room's length and width in feet, and use that number (or a little less) as the medallion diameter in inches as an upper guide, then check it against the fixture. In practice, 8 to 12 inches suits small rooms and hallways, 12 to 18 inches standard living and bedrooms, and 20 to 27 inches or more large rooms and grand chandeliers [1]. Choose about the fixture's width for a subtle look, larger for a bold one [1].
Medallion size is the question we are asked most by American customers. Too small and it looks like an afterthought; too large and it dominates the ceiling. Here are three ways to size it, and a chart in inches.
Method 1: room size
Add the room's length and width in feet. A 12 x 14 ft room gives 26: a medallion up to about 26 inches would not look out of place, though most people choose smaller, around 15 to 20 inches, for a standard 8 to 9 ft ceiling.
Method 2: the fixture
Van Dyke's suggests a medallion about the same diameter as the fixture for a subtle look, and larger than the fixture for a bolder look [1]. For a chandelier, a medallion roughly half to two-thirds of the chandelier's width is a common choice.
Method 3: ceiling height
Higher ceilings can take larger medallions because they draw the eye up; low ceilings suit smaller, flatter designs [1].
| Room size | Ceiling | Suggested diameter |
|---|---|---|
| Up to 10 x 10 ft | 8 ft | 8-12 in |
| 12 x 12 to 12 x 14 ft | 8-9 ft | 12-18 in |
| 14 x 16 to 16 x 20 ft | 9-10 ft | 18-24 in |
| Over 16 x 20 ft / grand dining | 10 ft + | 24-30 in+ |
Period and style
Georgian roses were often modest and classical; Victorian ones larger and more floral; Art Deco designs geometric and stepped [2]. Match the style of the house, not just the size.
