Very large spaces may require a very large fan or even multiple fans. In the above example we have a 60″ diameter fan in a 5m x 5m room.
SELECT YOUR ROOM SIZE
For a small room we would typically recommend a 48″ diameter fan or smaller. In the above example you can see a scale diagram of a 48″ diameter ceiling fan in a 3m x 3m square room.
In a medium sized room we would typically recommend a fan within the 48″ to 56″ diameter. The above shows an example of a 52″ diameter fan in a 4m x 4m square room. 48″ or 52″ diameter fans are by far the most common because they are well suited to common sized rooms.
An effective solution for a very large room may be two regular sized fans. In the above example we have 2x 52″ diameter fans positioned above a sofa and dining table. As fans are designed to cool individuals below them rather than an entire room, this may be a more effective cooling solution vs a large central fan.
