What Size Ceiling Fan Downrod Do I Need?

A ceiling fan downrod, also known as a ceiling fan extension, 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.

Match The Downrod Finish To The Ceiling Fan's 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?

Del Mar Fans & Lighting
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?
July 10, 2015 at 8:00 pm
Del Mar Fans & Lighting
Hi Brandon, There are a few different downrod types and sizes depending on the ceiling fan manufacturer. The fan you've bought could be single threaded or double threaded as well as an option of being 1/2 inch or 3/4 inch diameter. Feel free to contact us with the model information for a specific answer: sales@delmarfans.com

Ty Havard
I have an 11' 4" ceiling, so do I use the 18" downrod because I'm closer to 11'? The room is also 16' wide by 24' long so I am planning on 2 fans, what size should they be? Do I treat it like two 12 x 16 rooms, thinking 52's so not to overwhelm the room? Thanks.
August 4, 2015 at 9:53 pm
Del Mar Fans & Lighting
Hi Ty, It seems like you know what you want. Yes an 18" downrod will be the safe bet, a 24" can be used depending on the height of the ceiling fan itself. Two 52" ceiling fans will work great for space!

my ceiling is just shy of 2 stories. What size downrod should I use? I am replacing a builder special that died and the downrod there now is 43".
October 29, 2015 at 9:50 am
Del Mar Fans & Lighting
Hi Andrew, A two story downrod should be at least 36". The actual height of your ceiling and the height of the ceiling fan itself will tell you exactly how long the downrod should be. Keep in mind, the average hanging height is 8" above the floor. I hope this helps! I can answer any other questions at sales@delmarfans.com

Good Morning. I have 22" ceilings in a 18x18 room, what size downrod? what size fan?
November 1, 2015 at 10:19 am
Del Mar Fans & Lighting
Hi Allison, We ahve a wide variety of downrods as well as couplers that allow two downrods to be attached to one another. The blades of the ceiling fan should is not allowed to be below 7ft. In this case I would recommend a ceiling fan larger than 60" that would allow for a height of around 15ft. I hope this helps!

John Breinholt
I have a 22 foot ceiling. Is a 72 inch downrod sufficient, or should I go with 96 inches. Also, the fan has a 1 inch internal diameter downrod. Can I get by with a 3/4 inch or do I have to have it match the manufacturer?
November 22, 2015 at 10:59 pm
Del Mar Fans & Lighting
Hi John, It's recommended to fulfill the manufacturer's recommendations. The larger 1" downrod is used for a reason and indicates a sturdy ceiling fan. With that in mind a 72" downrod should be sufficient depending on the size of your room. The CFM of the ceiling fan will have the final say. I hope this helps!

I have a great room with 16 foot ceiling and it's 27' X 21'. It currently has 2 old ceiling fans from 1992. I am looking to replace them both but am unsure of the size fan and the correct down rod length. Can I get away with two 56" fans??
January 20, 2016 at 10:14 am
Del Mar Fans & Lighting
Hi Mai Lee, Thanks for a great question! Two 56" ceiling fans will do great in your room. The larger issue will be the downrod, depending on the new ceiling fan manufacturer. I recommend using a 60" downrod with your two 56" ceiling fans. I hope this is helpful!
January 20, 2016 at 10:24 am
Del Mar Fans & Lighting
Hi, A 72" downrod will be perfect to land your new ceiling fan at 7 feet if the total height of the ceiling fan is 22". If you want more specific answers our sales department is great! Sales@DelMarFans.com, I hope this helps.

Hello, I have a ceiling of 20 feet; what size downrod would you recommend?
February 10, 2016 at 12:14 pm
Del Mar Fans & Lighting
Hi Jimmy, Depending on the downrod diameter and your ceiling fan manufacturer I would reccommend a 72" downrod. The ceiling fan would, of course, need to have a high CFM to be effective. Some manufacturers have downrod couplers if you'd rather connect two 48" downrods. I hope this helps!

I'm putting a ceiling fan in an A-Frame loft that has a 15' peek. Fan will be used in reverse for pushing heat back down. Is it better to mount as high as possible or stay around the 8-10' height?
February 29, 2016 at 12:20 pm
Del Mar Fans & Lighting
Hi Brandon, Thanks for such a great question! Because ceiling fans, more than just circulating air, cool from evaporing moisture from our skin it's important to keep the movement of air in mind when deciding the location. Using a ceiling fan to keep a room warm will actually draw up the cooler air into the peak, displacing the warm air downward towards the ground. After grasping this concept I think it's easy to say an even amount of space between the cool air to be moved and warm air to be displaced would be the safest bet. Although half of 15' is 7.5' I believe utiilizing a 72" downrod would be the best option based on performance and aesthetics. If you need more information feel free to contact our sales department: sales@delmarfans.com. I hope this is helpful!

We are putting a ceiling fan in a room with 24' ceilings. Can we couple two 72" downrods or do we have to special order a single downrod?
March 11, 2016 at 9:44 pm
Del Mar Fans & Lighting
Hi Judy, That's a great question! Although two 72" downrods with a coupler is available and will work great, keep in mind there may be added wobble with the connetion in the middle. With that being said, some companies have longer downrods, like Casablanca's 117". The height trade-out for stability may be worth it. I hope this helps!

Barbara Brancheau
I am hanging a ceiling fan from a vaulted, 24' ceiling. Based on the questions and responses I see here, it sounds like 72" could be the appropriate downrod length. Next to our great room, we have an open hallway with a railing. The fan I'm replacing is on a 3' downrod. I understand I should come lower than that. My concern is that, if I drop the fan to 72", we'll be looking through the fan into the great room from the upstairs hallway. Because of that, should I consider a different length downrod, or is it acceptable to have the fan below the hallway railing?
May 2, 2016 at 8:39 pm
Del Mar Fans & Lighting
Hi Barbara, The correct downrod length is dependent on the slope of your ceiling. We have an education article walking you through the steps to determine your slope. The placement of your ceiling fan is personal preference, as long as it adheres to the NEC in your area. This is generally 7" from the ground to the fan blades. Keep in mind a running fan will be more audible the closer it is. I hope this helps!

I am hanging a ceiling fan in a "barn" like space. The ceiling is open, with what would be floor joists, exposed. The "floor joists" are approximately 7 feet above the floor. The distance from top of the "floor joists" to the peak of the space, where the fan electrical/mounting box will be located, is approximately 6 feet. (So distance from floor to mounting point (peak) is approx 7' + 1' + 6' = 14'. (Assumed 1' for height of "floor joists"). We would like to mount the fan motor with blades ABOVE the "floor joists" to maximum head room in the space. The fan is 3 bladed with an overall diameter of 56". What height would you recommend for the fan/blades? Do you feel we will get air flow through the "floor joists" to the space below?
May 8, 2016 at 6:24 pm
Del Mar Fans & Lighting
Hello Marty, The density of the floor joists will determine whether or not the 56" ceiling fan will be able to generate enough circulation in the barn building. The product of the dimensions of the exposed space in the building will provide the cubic feet of your building. The rating of your ceiling fan compared to your building's CuFt. will ultimately determine the usefulness of the ceiling fan. It will probably need to be larger than 56". I hope this helps

Marty Lustig
Thank you. 2 more questions: (FYI, We plan to have a 2nd fan about 10-12 feet away from the first fan.) 1. In your reply below, are you basically saying the closer the "CuFt of air moved by fan" is to the "CuFt of building", the more likely we are to get some air movement below the joists? (Or are you saying the inverse?) 2. From your experience, what height of the blades above the exposed floor joists is likely to provide success? High above joists? Close to joists? If you can give me a general sense based on your experience, we will then do some experiments with different length drop rods in the general area you recommend.

Marty, Each ceiling fan has a CFM rating. This is not alwasy the actual CFM's so I recommend exceeding this number. With 2 fans being used, essentially doubling the CFM, you will more effectively circulate the air. While using a downrod there will be movement so I would be more concerned with the fan blades being able to make contact with the joists. If you would like to discuss this further, please contact us at 800-724-5501
