Ultimate Guide to Ceiling Fans

Sizing your ceiling fan for your room
Choosing your ceiling fan to match your room size is the most difficult step in the process. There are two ways of doing this:
Blade Span Method: this is the easiest way, but it is not very accurate, as it assumes that fans with longer blades have higher airflow than fans with shorter blades - and that's not always true. Note that the 'blade span' in the table below is calculated by measuring the distance across the entire fan from one end to the other.
Airflow Method: if you have the airflow of a fan, this is best method.

The table below assumes a ceiling height of 8-9 feet (2.4-2.7 meters). If you have a higher ceiling you should go to the next room size up.

Room Floor Area Examples Recommended Blade Span Recommended Airflow

(144-225 feet² / 14-20.9 meter²)
Medium bedroom
dining room

Master bedroom

TV room
small garage
50-62" (1.3-1.6m) 2300-6500 feet³/min (3908-11043 m³/hr)
(over 400 feet² / 37.2 meter²)
Massive bedroom
large garage
open floor plan
Over 62" (1.6m) 5500-13500 feet³/min (9344-22936 m³/hr)

How much electricity will a fan draw?
On average a ceiling fan will draw less than a hundred Watt light globe.

Should I get a reverse cycle fan?
Absolutely, as it cools during summer and warms during winter. All the fans on Lighting Style are reverse cycle.

How much will a ceiling fan save in cooling (and heating) costs?
A ceiling fan can save up to 50% on cooling costs (compared to an air conditioner) and 15% on heating costs (compared to a heater).

Is a DC ceiling fan better or worse than an AC one?
Both DC and AC fans are completely fine and you should choose your fan according to your specifications and design requirements. That said, all things being equal a DC ceiling fan is generally more efficient and quieter.
