Sourcing ceiling fans comes with a number of considerations, from ensuring the right size for proper airflow, to meeting codes, to simply choosing one that best fits the design style. When the project calls for a ceiling fan, here are the six factors to think about to get it right:
1. Fan Size
The size of a ceiling fan is typically referred to as blade span, measuring the distance across the fan from blade tip to blade tip. The smaller the room, the smaller the fan needed:
| Room | Room Size | Ceiling Fan Size Needed |
|---|---|---|
| Bathrooms, Breakfast nooks, Laundry, mud or other utility rooms | Up to 75 square feet | 29 – 36 inches |
| Bedrooms, Kitchen, Dining rooms | Up to 175 square feet | 42 – 48 inches |
| Large Bedrooms, Family Rooms, Media rooms | Up to 350 square feet | 52 – 56 inches |
| Great Rooms, Other Large Spaces | 350+ square feet | 60+ inches |
A standard 12×12-foot room, roughly 144 square feet, is well served by a fan in the 44- to 52-inch range. A 52-inch fan is appropriate for rooms up to approximately 350 square feet, while a 60-inch or larger fan belongs in great rooms and open spaces above 350 square feet. As a result, a 60-inch fan will typically overwhelm a standard living room falling under that threshold.
2. Ceiling Considerations
| If working with a ceiling that is… | Choose… |
|---|---|
| 8 feet or lower | A hugger or flushmount fan |
| ~9 feet high | A low-profile ceiling fan, which will have a short downrod |
| 9+ feet high | A ceiling fan with a downrod, ensuring the total hanging height is no lower than 7 feet above the ground |
| Sloped | 1. A fan that specifies “sloped-ceiling adaptable” to ensure the downrod can rotate to a certain angle and that the fan hangs straight. 2. A separate sloped-ceiling mounting kit. |
3. Hanging Height
Two tips on ensuring a ceiling fan hangs safely and properly:
- The bottommost point of a ceiling fan should hang no lower than 7 feet above the floor.
- To determine how much downrod is needed, aim to leave a minimum of 8 inches between the ceiling fan blades and the ceiling for maximum airflow.
4. Location Rating: Indoor, Damp + Wet
Every ceiling fan carries a UL location rating that determines where it can be safely installed, and matching the rating to the space is as fundamental as sizing the blade span. Dry-rated fans are engineered for conditioned indoor rooms, kept away from moisture. Damp-rated fans are built for covered, moisture-exposed spaces that are not directly wetted, such as covered porches, sunrooms, and bathrooms. Wet-rated fans are constructed to withstand direct exposure to rain and water, making them the standard for open patios and pergolas. The distinctions are not interchangeable: an indoor, dry-rated fan should not be installed outdoors, a covered outdoor space requires a damp-rated fan, and an open exposure requires a wet-rated fan built for the elements. Lumens’ ceiling fans span dry-, damp-, and wet-rated options for indoor and outdoor spaces alike.
5. Airflow: Cubic Feet per Minute
To ensure the ceiling fan brings the breeze, look at CFM: Cubic Feet per Minute. This is how much air a fan moves. It is affected by the fan’s motor, blade pitch and the span of the blades. The higher the CFM number, the more air a fan moves. As a benchmark, efficient ceiling fans commonly move roughly 4,000 to 6,000-plus CFM, a useful range to reference when weighing performance. Fans equipped with DC motors deliver more airflow per watt, translating to quiet, energy-efficient operation. For a recognized standard of efficiency, look to the ENERGY STAR designation.
6. Blades, Lights, Style + More
With function comes form, and there are also considerations to make to ensure the right fan is chosen without sacrificing design:
Number of blades: Four- and five-blade fans are the residential norm. Because blade count has only a slight effect on airflow, selection should be driven by design and motor quality rather than the number of blades. Lumens offers 3-blade, 4-blade and 5-blade options across the collection.
Light Kit: Some fans come with an integrated light for overhead illumination; some include a cover that can be used over the light itself for a no-light look while still having the option. And others forgo the light altogether. The choice is really about preference; if forgoing the light, be sure the room still has the right layers of light to create general illumination for the whole room.
Style: A ceiling fan’s finish and blade form determine whether it recedes or commands the room. A white or matte finish lets a fan settle quietly into the ceiling plane, present but understated. A sculptural silhouette, by contrast, can become an architectural focal point that rivals a chandelier, reading as intentional, modern, and timeless.
Accessories: Far from the pull-chain of yesterday, smarter controls are the norm for many higher-end fan brands. It’s now possible to kit out every fan in your project with compatible add-on light kits, wall controls, remote controls and even smart hubs that control multiple fans via WiFi.
