Ceiling Fan Height From Roof

Most fan bodies including mounting hardware are 8 to 12 inches.

Ceiling fan height from roof.

This keeps the fan at least 7 above the floor and still provides for good air flow. 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. 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. However some manufacturers will include a 6 inch downrod.

For every two inches of ceiling clearance below this minimum airflow through the fan decreases by as much as 25 percent. Most ceiling fans come with three inch downrods that suspend the fan blades. 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. This will keep the blades at least 7 feet off the ground.

The optimum mounting height for a ceiling fan is 8 to 9 feet above the floor with a minimum of 7 feet for safety. However fan downrods can range all the way up to 177 inches depending on the manufacturer. You will want your new ceiling fan to hang between 8 and 9 above the floor regardless of ceiling height. 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.

For adequate air circulation the fan blades should hang 8 inches or more from the ceiling. For safety the bottom of the fan needs to be at least 7 feet above the floor. Most ceiling fans come ready to install on an 8 ceiling. Most ceiling fans come with a short downrod about 3 4 inches in length.

So whatever your ceiling height is in feet buy a downrod that will put the top base of the fan at 10 feet.
