How To Choose A Ceiling Fan – Size Guide, Blades & Airflow

The ceiling fan is a compact device designed to mix air masses. Installed on the ceiling and creates a comfortable microclimate in the room. It belongs to the category of simple household fans

and therefore has quite an affordable cost. Purpose and scope of ceiling fan application

Ceiling fans give the air mobility, creating a pleasant and comfortable coolness. It feels like a whiff of a light breeze. Due to the constant rotation of the blades and the mixing of air masses, the fan creates an optimal microclimate in any room.

As for the scope of application, this device can be used at almost any facility:

  • Apartments and private homes;
  • Offices
  • industrial workshops, etc.

Besides, ceiling fans can be installed even in outdoor areas. For example, in summer cafes, on verandas or terraces.


Features of Ceiling Fans

Of the useful features at once, it is worth noting the effective cooling of the air. Since they are mounted in the ceiling and placed mainly in the center of the room, this contributes to the even distribution of airflow throughout the room. This function is available in all models, the blades of which rotate to the left.

If you choose such a fan to change the direction of the blades, you will have more opportunities. After all, this model is able not only to cool the air in the room but also to heat it. In the latter case, the air will rise upwards and spread evenly throughout the room.

Models with variable rotation are considered to be more popular. And this is understandable because they help save on air conditioning and heating (up to 25-30%).

Also, there are models on sale that can regulate the level of humidity. They are most relevant for the kitchen and bathroom, where this is just a constant problem.


Distinctive features of ceiling fans

Almost all models support the reverse function. This allows them to work in two modes: “summer” and “winter.” The side on which the blades will rotate can be adjusted with a controller or a simple switch.

In summer mode, the fan blades direct the air from top to bottom. This creates the effect of a light breeze, which pleasantly blows people in the room.

And in winter mode, everything works a little differently. During the heating season, warm air usually rises and accumulates under the ceiling. And the cool opposite – is at the bottom.

Accordingly, the fan blades direct the air from the bottom up. That is, they “raise” cold air, which is mixed with warm, and then scattered throughout the room. This normalizes the temperature in the room and reduces the cost of heating.

Buying Guide For Ceiling Fan 

Although the ceiling fans and have a simple design, their choice should consider a lot of criteria. Otherwise, you can’t expect to work effectively.

To make this easier for you, let’s consider choosing the ceiling fan correctly and what parameters you need to pay attention to.


Before you choose a ceiling fan, the first thing to do is decide where exactly you will put it. Most often, the device is installed in the middle of the room because this is the only way to achieve an even distribution of air. If the room is spacious, then 2 fans are bought (or more – depending on the area).

It is categorically not recommended to mount a ceiling fan over the bed. After all, with long-term exposure to airflow, discomfort is possible.


Fan size

Dimensions are chosen from the room area. In this case, you can give the following recommendations on the choice of a ceiling fan:

  • 30′ – for small rooms (kitchen, bathroom);
  • 42′ – for medium rooms;
  • 52′ – for spacious rooms (living room, bedroom).


Ceiling height

Also, before you pick up a ceiling fan, you need to know exactly the height of the ceiling in a particular room. After all, it directly depends on the safety and convenience of accommodation.

For example, for low ceilings (2.4 m), models attached to a long rod are not suitable. First of all, they’re going to get in your way. Secondly, they will not be able to distribute airflow efficiently.

According to experts, the blades should be at an altitude of at least 2.1 meters from the floor. This ensures safety for people in the room. And for effective air circulation, the optimal height is considered to be 2.4 m (you can control such fans with remote control).


power supply

Ceiling fans consume as much electricity as regular fixtures. 220 B power grid will be enough for their stable operation.

But if the fan is equipped with a built-in lamp, perhaps the wiring will not withstand such a load. In this case, it is best to consult with an electrician. He will inspect the room and tell him whether to lay a separate cable from the electric flap or not.

Remember that the more functional the fan is, the more electricity it consumes. If your electric network can not withstand the load of the model with a built-in lamp and other functions – perhaps it is worth taking the option only with the right functionality and at optimal cost.



The ceiling fan is a device for creating a comfortable microclimate and part of the interior of the room. Therefore, it should have an appropriate appearance.

There are no recommendations here: choose a ceiling fan that fits the interior of the room. And that you like in style, color, and other moments.


The diameter of the blades

This parameter varies from 300 mm to 1590 mm. The higher this indicator, the higher the intensity of the blowout. But even the more space the device will occupy.

Therefore, over the question of choosing a ceiling fan, you have to think for yourself because you have to choose your own model for each room.


The material of the blades

Fan blades are made from:

  • abs-plastic;
  • Aluminum;
  • Metal;
  • plastic.

In principle, the quality of all options is about the same. The same plastic blades are inferior to metal, except that the latter look more stylish and seem more reliable.


Protection class

Two digits mark the protection class. The first shows the degree of protection from foreign objects, the second – from water penetration. Accordingly, you need to choose where you plan to install the fan and what conditions it will work.

For example, MODELS with an IP20 class are protected from foreign objects with a more than 12 mm diameter but do not have water protection. These are suitable for the bedroom or living room.

And fans with the IP44 class are protected from items up to 1 mm in diameter (wires, bolts) and splashes falling in any direction. They can be installed in the kitchen and bathroom.



The higher the option, the more effective the fan works. However, the main thing here is not to overdo it. The optimal speed is 2500 rpm.



Power should be between 15 w and above. Only then can the fan function be guaranteed.

More features to look out for when choosing a ceiling fan

The most important criteria for choosing a ceiling fan were considered above. But several additional points should also be paid attention to.


In addition to the high power, you also need to look at its noise level. After all, ideally, the motor should be silent. For a comfortable stay in the room, the noise level should not exceed the mark of 40-46 dB.



As noted above, the blades of ceiling fans can be made from different materials. And here you have to choose based on personal preferences. For example, wooden ones have an aesthetic appearance but need constant care and have a high cost. And plastic – easy to operate, are cheap, and in terms of functionality in no way inferior to wooden counterparts.

A big plus will be the ability to replace the blades in case of damage or failure. And this feature is not all models. It is best to take a fan with interchangeable blades to not buy a new device because of the slightest damage.

Also, make sure that the blades are treated with a special composition to protect against moisture. After all, if it penetrates the blades, it will cause their deformation. As a result, the fan will start to vibrate – and there is nothing pleasant about it.


Metal components

In high-quality ceiling fans, all-metal components are made of durable metal. And additionally, they have applied a special galvanic coating.

In cheap models, all these components are made of a gel. That’s why they serve for quite a short time.


Fixing the fan to the ceiling

For the fan not to be irritated by the constant noise and vibrations, it must have an anti-vibration design. Also, not superfluous will be shock absorbers.


Fan blades tilt angle.

The optimal angle is 12-14 degrees. Only in this situation can the efficient distribution of air by room can be guaranteed.



Choosing a manufacturer is a personal matter for everyone, so it isn’t easy to advise here. If you can not decide on the brand, then look at the products from world-renowned companies:

Each of them produces quality fans in a wide range, so you can easily find a reliable and durable model on any budget.


Useful tips for choosing a ceiling fan

Finally, consider practical tips to help you buy a suitable ceiling fan:

  • You can only put a fan without a barbell if the height of the ceiling does not allow it to be installed (but for the normal movement of air, the blades must be at least 2.1 meters from the floor and not too close to the ceiling);
  • To make sure that the ceiling will withstand the weight of the fan – consult with the electrician on this issue;
  • If the fan is installed on a high ceiling – take a model with wireless control or remote control;
  • If you need a productive model, look for products marked Energy Star (it distributes air 20% more efficiently than other analogs);
  • Always check that the fan blades are spinning in the right direction: in winter – clockwise, and in summer – against it;
  • If you choose a solution for the kitchen or bathroom – take a model that is suitable for use in rooms with high humidity;
  • If you want to use additional lighting in the room – buy a fan with an integrated lamp;
  • Try to put the fan so that its blades do not overlap the light source;
  • If the fan is mounted outside, ensure that all its components are waterproof and designed for such operating conditions.

And another important point that you also need to know: the fan does not remove moisture from the air. This seems to be an understandable thing, but many people forget about it for some reason.

Now you know the basic rules for choosing a ceiling fan. Yes, there are many criteria, but, in principle, there is nothing complicated here. Just pass on each option and thus select a ceiling fan, which suits you on all points.
