The size of the chandelier depends on the room and table size. To determine the size of a chandelier for a dining room based on the room size, add the length and width of the room in feet and substitute inches for feet, giving you the width of an appropriately-sized chandelier for the room. For example, for a 10’x13′ dining room, the length and width adds up to 23 which means width of the chandelier should a 23”. For determining the size of a chandelier based on your table size, the chandelier should be at least 12″ smaller in width than the width of the dining table.
It is recommended to have 3″ for each additional foot of space between the floor and ceiling. Thus, you can multiply your ceiling height (in feet) by 3 to get the appropriate height of a chandelier. For example, if your ceiling height is 10″, the chandelier height should be about 30″ (10x3).
You can hang chandeliers above a dining table or kitchen island. Below is a diagram for placement of chandeliers. In dining rooms with 8′ ceilings, hang chandeliers about 30″ above the table. (Add 3″ for each foot of ceiling height over 8′.) Remember to order extra chain for higher ceilings.
