The way to assess the Size for a Chandelier Canopy
A chandelier canopy is the cone-shaped cover which hides the wiring and also the junction box in the ceiling onto which the chandelier is mounted. A canopy only needs to be as broad as required to cover the hole in the masonry, so installing a canopy bigger than the hole is just an issue of taste. In many cases, a chandelier canopy is luxuriously using a ceiling medallion to create a prominent visual transition between the ceiling and the hanging chandelier.
Gauge the width of the junction box hole at the ceiling using a tape measure to determine the absolute minimum width necessary for the canopy.
Gauge the diameter of your chandelier across the widest points.
Measure the height of the room where the chandelier will be set up, from floor to ceiling.
Pick a ceiling medallion that is smaller than the diameter of the chandelier if the ceiling is less than nine feet from the floor or a medallion bigger than the chandelier’s diameter if the ceiling is higher than nine feet above the floor.
Expand the canopy which accompanied your chandelier above the middle of the ceiling medallion to ensure the transition between the medallion and the canopy will be visually appealing. If the ceiling medallion and canopy do not match well size or style-wise, measure the diameter throughout the middle of the medallion of the circumference which you just feel a canopy would match with the medallion very best, and select a canopy with diameter and style to match the medallion.
