Installing a Ceiling Fan in a Room with a Low or High Ceiling

Not all rooms are created equal. Ceiling fan companies realize this and provide the consumer with numerous accessories and parts to help you with installing a ceiling fan in a variety of locations. Ceiling fans can be mounted flush on the ceiling or by using a downrod can lowered down from the ceiling. Installing a ceiling fan to low is very dangerous, and locating the fan to high will reduce performance and efficiency.

Ideally when installing a ceiling fan you want a clearance of approximately 7 to 8 feet from the ceiling fan blades to the floor. Ceilings less than 8 feet should use a hugger or low profile style fan, typically this style of fan measures 10 inches from the ceiling to the bottom of the fan blades. Standard fans usually measure 12 inches deep and are ideal for 8 foot ceilings. A ceiling that measure over 9 feet should use a downrod. Here is a simple guide to help you achieve optimum performance with your ceiling fan.

Ceiling height 9’   – downrod length 12”

Ceiling height 10’ – downrod length 18”

Ceiling height 11’ – downrod length 24”

Ceiling height 12’ – downrod length 36”

Ceiling height 13’ – downrod length 48”

Ceiling height 14’ – downrod length 60”

If the ceiling is sloped you will need a special mounting bracket, this will allow the fan to swivel and hang straight down. Most manufacturers offer many types of mounting brackets, but confirm before you purchase your ceiling fan that the style you require is available. With a sloped ceiling you should also be aware of the angle of slope and the blades diameter to ensure proper clearance.
