The Perfect Fan Size for the Perfect Room

April 11, 2016

 

Who says size doesn’t matter?

 

The size of the fan usually refers to the diameter from a one blade tip to the other on the other side. The size of the fan usually determines the area that it covers. However the size of the motor (power/wattage) and the pitch angle of the blades also plays a big role in its performance.
There are several fan sizes each with recommended room size:

  • <48” (122 cm) – smaller than 4 m × 4 m area (16 m¬2), e.g. small bedroom

  • 48” (122 cm) – 4 m × 4 m area (16 m¬2), e.g. common bedroom/small office

  • 52” (132 cm) – 5 m × 5 m area (25 m2), e.g. common living area

  • 60” (142 cm) – 6 m × 6 m area (36 m2), e.g. common living area/outdoor

  • >60” (142 cm) – larger than 6 m × 6 m area (36 m2), e.g. large living area/outdoor

However there are a few fans that have varied sizes that are either bigger or smaller.
Generally speaking, it is OK to have a fan that is slightly lar
ger, as opposed to a fan that is too small. The reason being is that a small fan may not be able to spread the air across the room effectively. Instead what might happen is that there will be a strong column of air directly underneath the fan, while the edges and walls of the room will have little airflow. 


From a design aspect, white and light coloured fans typically fit in better in smaller rooms. This is because darker colours such as silver, black or dark wood tend to make the fan feel heavy. This may often make the room feel small or crowded as the fan is very noticeable. However it is important to keep in mind that these are only suggestions. Every room has its own unique décor and that in the end, it has to feel right for you.


In terms of the ceiling height, the most standard ceiling heights are around 2.4 m or 2.7 m. It’s also important to take note if the fan has a light, as some lights may hang low. Another thing to consider for low ceilings is the type of fan. Timber and plastic bladed fans are often better for low ceilings as they are safer, while metal blades can be dangerous in low ceilings. 


Ceilings above about the 2.7 m to 3 m mark become a little be too high for a standard ceiling fan. In this case an extension down rod would be necessary to bring the fan lower. The distance of between the ceiling and the blades with the supplied down rod is usually around 30 cm. The extension down rods that are available are 90 cm most commonly, however in some cases 180 cm rod can also be ordered. The extensions are designed so that the electrician installing the fan cuts the rod to the desired length, as in most cases 90 cm is too much.
