When hanging a chandelier over a bed, the bottom of the chandelier should be approximately 7 feet from the floor, according to SFGate. This height can be achieved by shortening the chain on the chandelier.
Hanging a chandelier over a bed is a romantic decorating idea, but it also requires additional bracing to keep it safe and secure. Appropriate sizes of chandeliers for the various bed sizes are a 36-inch-wide chandelier for a queen- or king-size bed and a 24-inch-wide chandelier for twin- and full-size beds. A heavy-duty swag hook and an expandable braced box kit provide the additional bracing needed for the weight of the chandelier.
