How to Determine the Size & Placement of a Chandelier – Use This Formula
Add the length and width of the foyer area together and convert the total into inches. Example: The area is 18 feet by 14 feet. Added together this equals 32 feet. Then convert your sum to inches: the chandelier’s diameter should be approx. 32 inches in width.
Additionally, consider the following:
Sizing By Table Size
To determine the width of your chandelier by the size of your table, assuming you have an open floor plan or just want to make the chandelier the centerpiece of the room, then the width or diameter of the chandelier should be one-half to two-thirds the width of the table. With ceilings over the standard eight feet, base the size of the chandelier on the room size or living space. Make sure the width of the chandelier is one foot less than the width of the table, to ensure six inches of clearance on either side of the table.
Hanging Two or More Chandeliers
To hang more than one chandelier over a table, divide the table width by the number of chandeliers plus one and use the result as the width or diameter for each chandelier. Install the chandeliers spaced the same distance apart as the width of the chandeliers.
Height of the Chandelier
Hang the chandelier approximately 30 to 34 inches over the table with an 8 foot ceiling height. If your ceiling is higher than 8 feet, mount the chandelier an additional 3 inches higher for each foot of ceiling.
For ceilings higher than 8 feet, add about three inches to the hanging height per foot. So if your ceiling is 10 feet tall, your lighting fixture should be hung 36-40 inches over the table.
