Ceiling Fan Height From Roof

You will want your new ceiling fan to hang between 8 and 9 above the floor regardless of ceiling height.

Ceiling fan height from roof.

If your ceiling is at least 8 high you may want to consider a fan with a short downrod rather than a flush mounted fan. On an 8 foot ceiling we recommend the standard pole which is a 3 4 inch downrod that comes with the fan. For safety the bottom of the fan needs to be at least 7 feet above the floor. Most ceilings are 8 feet high.

For adequate air circulation the fan blades should hang 8 inches or more from the ceiling. For every two inches of ceiling clearance below this minimum airflow through the fan decreases by as much as 25 percent. The optimum mounting height for a ceiling fan is 8 to 9 feet above the floor with a minimum of 7 feet for safety. This keeps the fan at least 7 above the floor and still provides for good air flow.

Most ceiling fans come with a short downrod about 3 4 inches in length. Standard ceiling fans include a downrod ranging in length from 2 inches to 10 inches which is suitable for standard size rooms with a ceiling height of eight to nine feet. When you hang a normal ceiling fan with a 3 4 downrod from a ceiling that is 8 feet high the blades will be about 7 feet from the floor. So whatever your ceiling height is in feet buy a downrod that will put the top base of the fan at 10 feet.

Most ceiling fans come with three inch downrods that suspend the fan blades. This will keep the blades at least 7 feet off the ground. Conversely spaces in the home with limited ceiling to floor height think bedrooms offices breakfast nooks etc require a low profile or flushmount ceiling fan. Most fan bodies including mounting hardware are 8 to 12 inches.

Most ceiling fans come ready to install on an 8 ceiling.
