How to size a ceiling fan

A fan can provide instant relief on a hot day. Even though a fan doesn't actually lower the temperature in a room, it can make it feel up to eight degrees cooler just by the effects of the breeze on your skin. A ceiling fan's height allows everyone in the room to enjoy the breeze and will give your room an additional attractive element, adding to the decor.


An important aspect in choosing a ceiling fan is determining what size you need. They need to be large enough to provide an adequate breeze but not too big for the space.

Kitchen ceiling fans provide an additional element by helping ventilate a room. These ceiling fans, sometimes referred to as "over island ceiling fans" can help remove smoke and odors from a room while keeping you comfortable over a hot stove. These fans often have shorter blades and should remain flush with the ceiling to pull unfavorable odors up and out.


Dining Room

A dining room is typically a more elegant room in your home. A ceiling fan with a sleek design can add more than comfort to the room. When considering the diameter of your ceiling fan, you want to take into account the room's square footage.


• Rooms up to 75 square feet = Ceiling fans 29-36 inches in diameter
• Rooms 76-144 square feet = 36-42 inches
• Rooms 144-225 square feet = 44 inches
• Rooms 225-400 square feet = 50-54 inches


Be sure to keep this in mind when measuring for any of your rooms.



A ceiling fan in the bedroom can be very beneficial. Not only will it help provide you with a more restful sleep by cooling down your room, it can also create a nice humming noise, which can be very relaxing.


If you're unsure about what look you like best, you can choose a fan with reversible blades. This allows you to easily change the look should you decide to switch up your bedroom decor.


Bedroom Ceiling Fan


Living Room

In a living room, you will almost always need a larger ceiling fan. Another thing living rooms almost always require is a downrod. A downrod allows a ceiling fan to be dropped from the ceiling, bringing the breeze closer to its occupants.

Most fans come with a downrod, although depending on the height of your ceilings, you may need to purchase an extender. One more thing to consider - vaulted or peaked ceilings. You will need the downrod attached to a special base so that the ceiling fan can come down and still operate leveled.


• Ceilings 9 feet tall = 6 inch long downrod
• 10 feet tall = 12 inches
• 12 feet tall = 24 inches
• 14 feet tall = 36 inches
• 16 feet tall = 48 inches
• 18 feet tall = 60 inches
• 20 feet tall = 72 inches
