What Size Ceiling Fan Downrod Do I Need?

Select the Right Downrod Length for Optimum Airflow and Comfort

 

A ceiling fan downrod is a metal pipe that connects the motor housing to the mounting hardware, stabilizing the ceiling fan and reducing the potential for wobbling. A downrod also aids in proper airflow by ensuring a safe distance between the ceiling fan blades and the ceiling, at least 8 – 10 inches, and between the fan blades and the floor, a minimum of 7 feet.

 

Downrods range in diameter and length depending on the ceiling fan type and application. Standard ceiling fans include a downrod ranging in length from 3 inches to 6 inches, which is suitable for standard size rooms with a ceiling height of 8 – 9 feet. However, fan downrods can range up to 177 inches depending on the manufacturer.

 

Here’s a simple guide to help you find the right ceiling fan downrod length for any room in your home. After reading, browse Del Mar Fans & Lighting’s selection of downrods from leading ceiling fan brands and shop our wide selection of ceiling fans.

Calculate Ceiling Fan Downrod Length

Ceiling fans provide optimal airflow when suspended 8 – 9 feet from the floor. Hanging a ceiling fan too high or too low can result in poor airflow in a room, causing your ceiling to work harder and use more energy than it needs to. The wrong height can also result in an ill-fitted looking ceiling fan.

 

A method commonly used to find the right downrod length is the ceiling height minus the height of the ceiling fan, minus the desired hanging height (usually 8 feet). For example, if your ceiling is 10 feet in height and your ceiling fan is 12 inches in height, you will need a 1-foot downrod to mount the ceiling fan 8 feet above the floor. You can also refer to the downrod length chart below for additional guidance in selecting the right measurement.

Additional Tips for Choosing a Downrod

When selecting a ceiling fan downrod, consider the length as well as the diameter, thread, and finish.

  • Interior Diameter - Downrods are commonly available with 1/2-inch interior diameters and 3/4-inch interior diameters; however, the Fanimation Fan Company offers downrods with 1-inch interior diameters. If you are selecting a downrod after purchasing a ceiling fan, verify the interior diameter of the downrod matches the fan you have at home. To ensure compatibility, choose a downrod from the same manufacturer as your ceiling fan.
  • Threaded vs Non-Threaded - Both threaded downrods and non-threaded downrods are safe to use during a ceiling fan installation. The downrods are secured by hitch pins and set screws that stabilize the downrod and prevent the rod from swaying.

  • Finish - Choose a downrod from the same manufacturer as your ceiling fan to ensure the downrod finish and the motor housing finish match. Some ceiling fan manufacturers may not offer a downrod in all available finishes, but they may offer a similar finish to ensure harmony. Many ceiling fan brands offer decorative downrod sleeves that sit on top of the motor housing, adding an ornamental detail.
