Ceiling Fan Height From Roof
However some manufacturers will include a 6 inch downrod.
Ceiling fan height from roof. We also recommend the standard downrod on a 9 foot ceiling. 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. Most fan bodies including mounting hardware are 8 to 12 inches. Most ceiling fans come with a short downrod about 3 4 inches in length.
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 ceiling fans come ready to install on an 8 ceiling. For safety the bottom of the fan needs to be at least 7 feet above 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. For every two inches of ceiling clearance below this minimum airflow through the fan decreases by as much as 25 percent. This keeps the fan at least 7 above the floor and still provides for good air flow. 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.
On an 8 foot ceiling we recommend the standard pole which is a 3 4 inch downrod that comes with the fan. Most ceiling fans come with three inch downrods that suspend the fan blades. The optimum mounting height for a ceiling fan is 8 to 9 feet above the floor with a minimum of 7 feet for safety. For adequate air circulation the fan blades should hang 8 inches or more from the ceiling.
Most ceilings are 8 feet high.
