What Ceiling Fan Size Should You Get?

Selecting the right ceiling fan size is important to maximize airflow and minimize costs to keep your house energy efficient. Ceiling fans not only add to the décor of your house, they also make it more comfortable and relaxing. Making sure each room has sufficient airflow is the ceiling fan's job, so it is important that it matches the room it is in.

To optimize the performance of your fan, its size should be appropriate to how small or big your room is. For instance, a small fan in a large room would need to run at higher speeds for it to be effective. In the same way, a large ceiling fan in a small room would be too much and is a waste of energy.

Ceiling fans come in different sizes, number of blades, and blade spans that work with the square footage of your room. The fan blade length is important because the longer the blade, the wider area it can circulate the air around. Read more below to learn about how ceiling fan size is related to the room size.

Small Rooms

Small rooms include small bedrooms, laundry rooms, dens, and foyers. The room size should be up to 100 sq. ft., or 10 ft. x 10 ft. in dimensions. These rooms have a tendency to be hot because of the small space.

Putting a fan in these rooms would greatly improve air circulation and regulate humidity. For optimal performance, your ceiling fan should have a blade span of up to 42 inches.

Medium Rooms

Medium rooms would include kitchens, average size living rooms, and dining rooms. The room size can be between 100 sq. ft. and about 200 sq. ft., or 15 ft. x 15 ft. in dimensions. These types of rooms are typically the most used and where people usually gather, so it is just imperative to have proper airflow.

Putting a ceiling fan greatly improves the comfort level and keeps the rooms cool during summer and warm enough during winter. Ceiling fans with 42 inches to 52 inches blade spans would be ideal for these types of rooms.

Large Rooms

Large rooms like family rooms and master bedrooms have better air circulation in general, but are also susceptible to hot and cold spots. Room size can range from 200 sq. ft. to 400 sq. ft., or have up to 20 ft. x 20 ft. dimensions. These rooms also tend to have higher ceilings or vaulted ceilings, a larger and stronger fans are required.

For these types of rooms, ceiling fans with at least 52 inches blade span are ideal to distribute as much air as possible and keep the flow going.

Great Rooms

Great rooms are not common but are still present in some homes. These are usually large foyers and open-concept living areas. Like large rooms, there should be enough circulation by itself, but ceiling fans are still necessary to regulate the temperature a certain times of the year. These rooms are over 400 sq. ft. or at least 20 ft. x 20 ft. in dimensions.

Due to the massive size of great rooms, it is recommended to have at least two ceiling fans to cover as much area as possible. Doing this will also take off the pressure on a single fan to run in the fastest setting and therefore consume more energy. If only one fan is used, it is recommended to use fans with blade spans of at least 60 inches.
