Sorted by diameter
When looking for a suitable ceiling fan it is made clear very quickly that there is not only a large amount of shapes and colours available, but also that the models come in different sizes. In order to give a better understanding, almost all producers arrange their products by type of motor and their features as well as diameters. There are some easily recognisable textures and sizes that can be found at almost every brand.
Size does matter
But why are ceiling fans offered with different diameters anyway? The decisive factor for the recommendable diameter is the size of the room the chosen ceiling fan is going to be used in. The recommended diameter can be deducted from the surface area of the room.
Calculate the right diameter
The smaller the room is, the less air needs to be circulated inside; the larger the diameter of a ceiling fan, the better its ability to circulated air mass. In short that means small room, small diameter, big room, big diameter. In a table of room sizes the fitting diameter can be figured out within minutes. This should be the first step before deciding about design and colour of the ceiling fan.
In-between sizes
Judging from experience, it is safe to say that not every room is square-shaped or fits the criteria of the sheet of room sizes. Futhermore, ceiling fans work towards the ground within more square-shaped environments. Particularly when it comes to rectangular, long rooms it can cause insecurities because of the right size. In order to clear any doubts, rooms are therefore divided into effect squares, resulting in an amount of recommended devices with the corresponding diameter. When having to decide between two sizes, one should always go for the larger diameter, because there is always the possibility to lower the rotation speed.
