What Size Ceiling Fan Downrod Do I Need?

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.

Both threaded and non-threaded downrods are secure to use during a ceiling fan install.

  • 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.
     

Choose a similar downrod finish as your ceiling fan finish.

Hi Tutai, We don't carry 120" downrods but many manufacturers have couplings that allow multiple downrods. It seems two 60" downrods with a coupling would be the best fit for you and your church. If you'd like to send an email to sales@delmarfans.com we'd love to see which fans you're looking at and help you more depth! I hope this helps.

I have an uncommon problem. I cannot get heat upstairs in my small house. I would like to put a 24" reversible fan in the stairwell to move air up in the winter time. I have a 12' ceiling over the first landing. To get the air up more effectively should the fan be closer to the upstairs?

Hi Patricia, Thanks for the great question! There are exceptions to the ceiling fan direction "rules". Generally you would want to switch the direction of the ceiling fan based on the winter or summer seasons and whether you want to distribute warm or cold air. The exception is with a second-story ceiling or a high vaulted ceiling. Whether you should place the ceiling fan higher or lower in relation to the second floor is based on what you need to accomplish. The ceiling fan is generally too high to create a noticeable difference in wind chill so the fan can stay on the best setting for your purpose, in this case clockwise will pull the warm air up towards the upstairs bedrooms. I hope this answers your question! -Alex

Hi Patricia, Thanks for your great question. In order to heat the upstairs you want to install the ceiling fan closest to the room you are trying to heat or cool. I hope this answers your question!

Does it matter if the down rod is threaded or non-threaded. Will the fan I purchased fit either one as long as you put the pin in it?
