Calculating the correct size ceiling fan for a vaulted ceiling is not difficult.
A ceiling fan is an economical way to cool the occupants in a room. It is also a decorative feature that often includes a light fixture. It is not difficult to calculate the size of ceiling fan necessary for a room with a vaulted ceiling. During the warm weather seasons, you can raise your thermostat 2 degrees and save up to 14 percent on your energy bill by using a ceiling fan, as stated by the Energy Star website.
Instructions
1. Measure the length and width of the room where you want your ceiling fan.
2. Multiply the two measurements together to calculate the square footage of the room. Generally, a room that is up to 50 square feet requires a fan blade span of 30 inches. For a room that is 51 to 100 square feet, select a span of 36 inches; up to 200 square feet, a 42-inch span; and use a 52-inch span fan blade for rooms that are 200 to 400 square feet. Any room size larger than 400 square fan blades with a span of 54 inches, according to the This Old House website.
3. Look for a mount made specifically for vaulted or angled ceilings. Generally, these are called slope mounts.
4. Add a downrod to the sloped mount so that the ceiling fan is positioned 8 or 9 feet above the floor. This creates optimal airflow in the room.
