Ceiling Fan Size and Mounting Guide

Fan Size

 
When selecting a ceiling fan size, consider the size of the room it will be placed in. In the chart below, we provide recommendations for ceiling fan size based on the square foot measurements of a room. It's important to note that traditional ceiling fans are measured by the diameter of the fan from blade tip to blade tip (from the end of one blade to the end of the opposite blade). The most common fans range from 50 to 55 inches in diameter.


Room Size (in square feet)Suggested Fan Size
100 sq. ft. or smaller29-36 inches
101-144 sq. ft.38-42 inches
145-225 sq. ft.44-46 inches
226-400 sq. ft.48-54 inches
400+ sq. ft.56-60 inches

Fan Mounting

 
A ceiling fan should be positioned between 7 and 9 feet above the floor for optimal airflow. A mounting system should be chosen based on the room's height and mounting angle. We define the four common mounting systems below. Mounting systems can be bought separately from the fan or can be a part of the fan.

  1. Standard. The standard downrod length is 3-5 inches.
  2. Extended or downrod. Extended or downrod mounts are used with tall ceilings, allowing the fan to hang at the most effective height. Choose the correct downrod length to allow your ceiling fan to hang 7-9 feet above the ground.
  3. Flush. Flush mounted ceiling fans should be used when the ceiling is 8 feet tall or shorter. This allows the fan to hang at the proper height for ideal airflow.
  4. Sloped. Most ceiling fan mounting systems are meant to be installed on a flat ceiling. However, special sloped mounting adapters can be purchased for ceilings with a pitch or angle.
To cool a room, your fan should rotate counterclockwise. This pushes cool air downward. To heat up a room, switch your fan's rotation to clockwise, which pushes warm air down.
