Tips For Buying the Right Ceiling Fan Size

Ceiling fans are a welcome addition to any room. If you want to maximize its use, it is important that you buy the correct size of ceiling fan for a room. They come in a wide variety of sizes, so consider the following tips to help you determine what ceiling fan size you need for the room and the type of ceiling you have.

Ceiling Fans for Small Rooms

Not surprisingly, smaller rooms need smaller ceiling fans. Ceiling fan size can be determined by measuring the height and width of your room. If you are installing a fan in a patio, bathroom, den, or small bedroom, it is important to measure the height of the ceiling. If you have a low hanging ceiling you may want to purchase a flush mount ceiling fan. Flush mount or hugger fans hug the ceiling so they do not hang too low when the ceiling is less than 8’ high. Low ceiling adaptors or close-to-the-ceiling downrods are accessories specially designed for ceilings lower than 8’ and that fit many regular ceiling fans.

If you have a standard 8’ ceiling, you probably want to look for a fan with a short downrod rather than a flush mounted version since air circulation is usually better when blades have a little more distance from the ceiling. Most fans come ready to hang on a standard 8’ ceiling.

The size of the room is also important. If you have a narrow room or very small area, a short blade span of 29” to 36” is recommended. These mini ceiling fans are ideal for tiny spaces such as bathrooms, stairwells, and laundry rooms. If your room is approximately 9’ x 9’ you will want to consider ceiling fans with a blade span of 40” to 48”. These small room ceiling fans are ideal for smaller bedrooms and home offices.

Ceiling Fans for Large Rooms

Larger rooms can accommodate almost any size ceiling fan. If you want the air to circulate throughout the entire room it is probably best to invest in a ceiling fan with a larger blade span. Standard room ceiling fans with blade spans between 50” and 56” are perfect for medium to large rooms like larger bedrooms, kitchens, dining rooms, and living rooms. This size will sufficiently circulate the air without being overbearing in the room. If you have a large living room but want the air mostly concentrated over the seating area, a medium size ceiling fan will be adequate.

In larger living rooms or great rooms where you need the air to flow throughout the entire room you will want a large room ceiling fan with a blade span of about 60” to 72”. This blade span will generate more airflow and will be able to push the air through the entire room easily. Another option for very large rooms is to use multiple fans evenly spaced throughout the room to ensure a high level of even air comfort in every area of the room. Talking to an experienced ceiling fan consultant is often helpful in deciding how best to efficiently maximize air comfort and airflow in very large rooms.

The downrod is another important factor to consider when buying the right size of ceiling fan for your room. The downrod is the pole that allows the fan to hang from the ceiling at varying lengths. For larger rooms the downrod should be between 6” to 96” long depending on your ceiling height. Optimally, the fan should be 8’ to 9’ from the floor to maximize airflow.  If a fan is too close to the ceiling the airflow will decrease and you will lose out on the cooling effect. Making sure that the fan is approximately 18 inches away from walls, sloped ceilings, or other lights will help ensure its efficiency.

Ceiling Fans for Vaulted Ceilings

If you have a vaulted ceiling in your home the guidelines for ceiling fan size and downrod length may be a bit different.

For one thing, differing heights at various points along the ceiling would obviously require different downrod lengths. You should make sure that the downrod is long enough so that the blades are approximately 18” from the sloped side of the ceiling closest to it (or even more for better airflow) and should still allow the fan to hang 8’ to 9’ from the floor.

Different slopes can affect the hanging system as well. Many premium ceiling fans come ready to hang on a slope of 29 to 32 degrees. For steeper slopes, sloped ceiling adaptor kits are often available from the premium manufacturers. Casablanca Ceiling Fans, for example, has a sloped ceiling fan adaptor kit that can be used on a ceiling with up to a 56-degree slope and can be used on fans by other manufacturers as well.

Determining the right ceiling fan size can be difficult as well. The blade span of vaulted ceiling fans can vary. If your vaulted ceiling is low and your slope is small, you should determine the fan size based on the room size. If you have a higher ceiling and need a longer downrod, it’s best to purchase a fan with a larger blade span that can fully circulate the air. In any case, for vaulted ceiling configurations, contacting a local or online ceiling fan specialist is your best bet to make sure you buy and install the perfect size ceiling fan for the room.
