Airflow rating or flow rate is the most effective way to measure the efficiency of a ceiling fan.
Choose the largest fan with the highest wind speed that will fit into the space without overwhelming it visually to calculate the size of the largest fan that will fit the room just leave 2 to 3 feet between the closest wall and the tip of the blades 3 feet for ceilings 9 feet or.
The amount of the air volume is determined by the size of the fan and motor.
Enter the air flow coverage specification of the fan you anticipate using in square feet or in cubic feet per minute.
The amount of airflow a ceiling fan can produce per minute is most commonly measured in cubic feet per minute or cfm.
This figure should be compared with the room s overall cubic footage when deciding which fan will work the best for each.
A general rule of thumb is to choose a fan with 26 to 36 inch blades for a room up to 75 square feet a fan with 36 to 42 inch blades for a room from 76 to 144 square feet a fan with 44 inch.
