Ceiling Fan Basics
Ceiling fan blade spans range from 29 – 54 inches - the most popular being the 52-inch model. To determine which size you need, measure the room where the ceiling fan will be installed and follow these guidelines:
|Room Dimensions||Suggested Fan Size|
|Up to 75 ft2||29 – 36"|
|76 – 144 ft2||36 – 42"|
|144 – 225 ft2||44"|
|225 – 400 ft2||50 – 54"|

Ceiling fans should be installed, or mounted, in the middle of the room and at least 7 feet above the floor and 18 inches from the walls. If ceiling height allows, install the fan 8 - 9 feet above the floor for optimal airflow.
- Standard mounts come with a 3 – 5 inch downrod, which is the metal pipe that extends from the ceiling bracket to the top of the fan. Downrods are usually either 1/2 or 3/4-inch in diameter.
- Extended mounts can be used to hang the ceiling fan at the desired 8– 9 feet from the floor for tall ceiling heights. Downrods can be purchased from 6 inches (9 ft ceiling) to 120 inches (20 ft ceiling). Check with the manufacturer or sales associate to determine the right downrod length for you.
- Flush mounts anchor the fan directly against the ceiling. Most standard fans can be installed as a flush mount however, many manufacturers sell “hugger” or “low profile” ceiling fans that are specifically designed for this purpose. Hugger fans are ideal for rooms that have ceilings under 8 feet in height or in situations where a fan with optional light would hang down too low. Hugger fans will not move as much air as a regular fan because the blades are closer to the ceiling.
- Sloped mounts are used for angled or vaulted ceilings.

Wet/Damp Rating. Placing a ceiling fan in a bathroom or other humid locations? Purchase a fan that has been UL listed with a “damp” rating. For fans that may come in direct contact with water, like on a patio or front porch, look for a UL “wet” rating. These fans include features such as sealed/moisture resistant motors, rust resistant housing, stainless steel hardware, and all weather blades.
