What size should my ceiling fan be?

What size ceiling fan do I need?

The size of your ceiling fan is important for looks, performance and safety.  

A common misconception to be aware of when searching for the right ceiling fan for your space is the very fact that the actual size of the fan is not what will determine it's performance. In equally important factor to take into consideration is the power of its airflow, otherwise, know as CFM (Cubic Feet per Minute). A fan that has a 60" diameter but gives off an airflow of 3500 CFM is very inefficient for its size and will not have the desired effect in a large room. It is true that usually the larger the fan the higher the CFM but there are a few other factors that effect it as well, such as RPM (number of Rotations Per Minute), Blade Pitch, number of blades and distance of blades from the ceiling. However, in addition to the CFM the size of the fan is important as well. A bigger fan will distribute it's airflow over a larger area while a smaller fan will concentrate its airflow over a smaller area.

 

Room Size

Blade Span

CFM

Under 80 sq. ft

29" - 38" 

Under 2500

81 - 160 sq. ft.

38" - 44" 

2000 - 3000

160 – 240 sq. ft.

45" - 52"

2500 - 4500

240 - 400 sq. ft.

53" - 72" 

3200 - 7000

  

Ceiling fan height 

For a ceiling that is lower than 7.5 feet, for safety reasons you'll need to get a hugger/flushmount fan.

As a general rule, for the strongest airflow, your ceiling fan should hang no more than 8 or 9 feet from the floor. For high or vaulted ceilings, purchase a downrod that will bring the fan down to the right height and make sure the fan has a long enough pull chain or comes with a wall switch or remote control

If you don't need a hugger fan we do not recommend it because the airflow is usually not very strong being that it's so close to the ceiling.
