 How To Size a Medallion for a chandelier ? 


  Watch Tiktok video


 Let Dr Details Explain

 about Sizings 

Ceiling Medallions were created as fire barriers in the early 1800's when lighting was either oil, gas, or candle power.  To avoid fires they were made of non combustible plaster.  As a design precedent medallions are always larger than the lighting fixture.  If they are the same size as the light fixture they simply look wrong and this effect is amplified the higher the ceiling is.


  Here is a simple calculation to guide you 

  multiple widest part of the chandelier  by 38.2 % 


  Sizing is based on the Golden Rule called PHi

  This is the ratio calculation PHi (1.618) 


  Here is a simple example calculation to consider

  1- (.618) = (.382)  ie 38.2%

  This keeps within the Golden Rule of Phi


  18" chandelier (widest point) x 1.38 = a 25 inch medallion


  No rules rule so select 29", 25" or what ever matches your design


  Always remember that when you view the medallion mounted on the

  ceiling it will appear much smaller from your perspective at a lower level

  By selecting one that uses the  golden rule calculation, it will appear to

  be the right size with the correct visual distortion with higher ceilings





 The Hole Size and the Chandelier Canopy


  Photo shows the octagon box in the ceiling, the canopy which is part of the chandelier


 The Chandlier


 Does NOT

 go through

 the Hole

The chandelier canopy fits up to the medallion and does not go through the hole in the medallion.  The hole gives you access to the threaded rod affixed to the bracket that attaches to the receptacle box.

  Can I use any construction glue?

  Approved Construction Adhesive 


  Simple Answer:   No

  this material otherwise it might damage the medallion.

 Can I use any latex filler to cover the gaps?

 Spackling Compound


  Simple Answer:  Yes but ...


  If you use latex filler to cover the gap between the medallion and the

  ceiling it invariably dries out over time and shrinks.  This vinyl splacking

  compound is way better as it dries hard and can be sanded.

  Always  read the instruction before applying.

 What is a Canopy?

 Photo shows canopy



 The chandelier's canopy or cupola is shown above


 The canopy covers the electrical wires and the receptacle box in the ceiling

 The receptacle box is usually 3-3/4" octagon shape and is attached to the



 The canopy is attached to the treaded rod where the wires come out of the

 receptacle box


 The canopy does NOT go through to hole of the medallion rather it sits

 on the surface of the medallion


 The medallion may have a flat area around the hole or it may have a design

 You can select a medallion with a center flat area slightly larger than the

 diameter of the canopy or you can put the canopy directly to the decorative

 motif on the medallion covering part of the pattern. Since it is high up it is

 unlikely to be noticed. 


 For deep medallions you will need to acquire a longer threaded rod

 or extender to attach the connector
