Small ceiling fan

Ceiling fans are available in many sizes so you can choose the fan best suited for your room size. A small ceiling fan is ideal for rooms that are small, that is, for places that are less than or up to 75 sq ft. These fans can efficiently cool small rooms, office spaces, and other such small personal spaces.

Size of A Small Ceiling Fan

During summers, every room requires a fan for cooling and ventilation purposes. This is even more essential for small rooms and spaces since, without proper air circulation and ventilation, they can get very stuffy and hot.

Generally, a standard size small ceiling fans have a blade span ranging from 24″ to 36″ which makes them ideal for kitchens, hallways, walk-in closets, study rooms, to name a few. However, these fans can also be used in large rooms in case you want one fan to cover one part of the room. So, you can use two or more of small ceiling fans, each of which will cover one part of the room, thus providing an even and better air circulation throughout the room. They are lightweight and user-friendly.

Room Size And CFM (Cubic Feet per Minute)

While purchasing a ceiling fan, it is essential to keep in mind the room size. This process has been made quite easy for consumers now, as various fan manufacturing companies offer an array of fan sizes, in different styles and colours. Choosing the right size fan according to the room size optimizes the efficiency of the fan and allows it to spread the air in every corner of the room.

Here is a size chart that’ll help you to choose the ideal fan for your room.

Blade Span Room Size
29″ to 36″ Up to 75 sq. ft
42″ to 48″ Up to 175 sq. ft
52″ to 56″ Up to 350 sq. ft
60″ or larger Bigger than 350 sq. ft


The number of times the air enters or exits a room in an hour is calculated by following the HVAC system. A fan’s efficiency regarding airflow is measured in cubic feet per minute (CFM). The CFM of a room can be determined mathematically by calculating the cubic area of the room and the desired rate of air circulation for the room. This way you can choose the perfect fan for your room.

How to calculate the CFM for a room?

  1. Measure the dimensions of your room (width, length, and ceiling height).
  2. Now multiply these measurements to determine the cubic footage of the room. For example, if a room is 10 feet wide, 12 feet long and 8 feet high, then the room is 960 cubic feet.
  3. In this step, you need to multiply the cubic area of the room by the number of times you desire the air to circulate or exchange within an hour. For instance, if you expect the air to be exchanged twice per hour, multiply 2 times 960 to get 1,920.
  4. Finally, to calculate the CFM, you need to divide the above amount by 60. So, if you divide 1920 by 60, the CFM of the room will be 32.

Classification of Small Ceiling Fans

Small ceiling fans are available in many unique designs and shapes. They can be classified into various categories by:

Blade size – Small ceiling fans can range from very small to average and standard sized blade span, such as 4” to 12” and even from 38” to 48”.

Motor – While the small ceiling fans that are equipped with super-efficient DC motors deliver excellent air circulation, those with normal motors deliver decent airflow. But the DC ones are an obvious choice, not just because of their performance but also for energy saving. Also, dual motor fans can circulate air over a greater area.

Rating – Like all other fans, these fans also have ratings based on their efficiency, CFM, and quality. While the ones that are rated 4 or 5 are excellent, the ones with ratings of 3 or 2 are average and below average, respectively.

Location Type – Small ceiling fans can be classified under dry, wet, and damp depending upon their placing location. The dry ones are ideal for indoors while the other two variants are best suited for places with high humidity. Damp and wet ceiling fans are made from materials that are resistant to rain, dampness, and are anti-rust.

Why 42 Inch and Smaller Ceiling Fans Are Great For Your Home?

Often, the buying guides of different fan manufacturers have one common suggestion for every buyer – a 42” ceiling fan is the ideal fan for a home. While it is true that a large fan provides greater air circulation, there are other considerations to make such as the motor quality, blade span, room size, ceiling height and so on.

Using a 42” ceiling fan has the following advantages:

  • The size of this fan is neither too small nor too big, thus making it a perfect match for standard sized rooms. Also, they are not very heavy and are easy to install.
  • Most models of this size are quite reasonably priced, so they don’t burn a hole in your pockets. Besides, you can customize the look of these fans with light kits or pull chains to jazz them up.
  • Ceiling fans with 42” blades are designed in a way that allows good air circulation and ambient temperature within the room. If a room is huge, installing two 42” fans would provide better airflow in every corner of the room.
