Ceiling fans are measured by the full size of their blade span (also called blade sweep), which is the diameter of the circle that you see when the fan blades are in motion. Or, in other words, fan blade span reaches from the tip of one fan blade to the tip of the blade directly across.
How do you determine ceiling fan size?
Compare the fan blade sweep, or diameter, to the room's square footage to determine the right ceiling fan for your room.
- Install a fan with a 42-inch sweep in rooms up to 144 feet.
- Install a fan with a 44-inch sweep in rooms from 144 to 225 feet.
- Install a fan with a 52-inch sweep in rooms from 225 to 400 feet.
What does 1200mm mean in ceiling fan?
The air delivered by a ceiling fan is proportional to its sweep. The blades on this ceiling fan have a sweep length of 1200 mm, which means it can deliver the optimum amount of air suitable for any large room.
