Room Area = Length x Width; Fan Size based on sq ft: <=75=29-36 inches, <=144=36-42 inches, <=225=44-50 inches
Example: A 12 ft x 14 ft room (168 sq ft) needs a 42 inch to 52 inch fan. For best airflow in this 168 sq ft room, choose a 52 inch ceiling fan
How high should a ceiling fan hang?
Blades should be 7-9 feet from the floor and 10-12 inches from the ceiling. Use flush mounts for ceilings under 8 feet.
Does blade count matter?
More blades create smoother airflow but may move less air. 4-5 blades are optimal for residential use. 3 blades work well for modern/industrial styles.
