Ceiling fans can be the perfect addition to your living room, bedroom, or any other part of the house. They provide a significant amount of comfort and relief from the heat and humidity. Many homeowners are now considering purchasing ceiling fans because they offer a wide range of benefits that include saving on power bills and enhancing the look of a room. They are also very easy to install, require minimal effort, and can be added to any space whether large or small. If you're considering purchasing a ceiling fan for your home or office, it's important to first assess which size will best suit your needs. This includes determining how much space you have in your room with regards to height and width as well as how many blades you want on the fan. When it comes to the right size of ceiling fans for your space, you need to keep some factors in mind. Ceiling fans come in a wide range of blade spans, from small mini fans with a blade span of 18 inches up to large ceiling fans with a 68-inch blade span. Choosing the right ceiling fan size will optimize the fan's efficiency and make the fan look right in the room. 


How are ceiling fans measured? 
Ceiling fans are measured in two ways - Blade sweep and Down rod length.


Blade sweep: Blade sweep, also known as the full size of a fan’s blade span, is the diameter of the circle that you see when the fan blades are in motion. Or, in other words, the fan blade span reaches from the tip of one fan blade to the tip of the blade directly across.


Down rod length:  This determines how low the ceiling fan will hang from the ceiling once installed. Spaces with tall ceilings will benefit from a ceiling fan with a longer down rod length. Rooms with low ceilings will need a reduced down rod length to accommodate the shorter floor to ceiling height.


Factors to consider before getting a ceiling fan 
The most important factor to consider before getting a ceiling fan is the room size.


 Room size: The size of the room is one of these factors that must be considered before purchasing a fan. There are two ways to measure how much space a fan will take up. One way is to measure the width or height of the room and then get a fan with the same dimensions as well as length. The other way is to get an oscillating fan that has more than one speed setting.
 
Common room sizes and our recommended fan size:


1. For smaller spaces/room (6’ by 6’ or smaller) 
For very small areas such as nooks, stairwells, laundry rooms, walk-in closets, or small bathrooms, we recommend 29" to 36" ceiling fans. These fans fit nicely into tiny spaces. Several of these mini ceiling fans are damp or wet rated and therefore designed to withstand frequent exposure to moisture like in bathrooms or outdoor patios.


2. For small rooms (9’ by 9’ or smaller) 
For rooms smaller than 9' x 9' we recommend 40" to 48" ceiling fans. These fans are ideal for small bedrooms, home offices, dens, and full bathrooms. For bedrooms, whisper-quiet ceiling fans are often needed.


3. For standard room (10’ by 10’ to 16’ by 16’) 
Standard rooms vary from 10'x10' to 16'x16' (100 to 256 sq ft) and includes large bedrooms, living rooms, and large kitchens. For these, we recommend 50" to 58" ceiling fans.
Powerful fans are significant in cooling rooms of this size. Under-sizing and underpowering fans often result in constantly running the fan at high speeds which increases energy consumption, delivers a stronger airflow, which may be less comfortable, and can limit the life of the fan. Whisper-quiet fans should also be considered when selecting fans in bedrooms.


4. For large rooms (17’ by 17’ to 20’ by 20’) 
Large rooms such as family rooms, large living rooms, large master bedrooms, and outdoor patios (ranging from 289 to 400 square feet) are best with 60" to 72" ceiling fans. These fans provide a large cone of air and can provide cooling throughout the room. Making sure the fan has reasonable power and airflow (CFM's) is very important for this size fan. Having a whisper-quiet fan can be very significant in bedrooms.
For great rooms, bonus rooms, game rooms, combination rooms, or any room or area larger than 400 square feet, we recommend using multiple standard size room fans ranging from 50" to 58" each. Powerful motors with high airflow (CFM's) are important. Ultimately, the right size fan for a room is not determined by the size of the room alone. You must also consider the layout of the room, where the fan will be positioned in relation to the area where the airflow is most needed as well as how high the ceiling is. 

5. For very large rooms (20’ by 20’ and bigger) 

For great rooms, bonus rooms, game rooms, combination rooms, or any room or area larger than 400 square feet, we recommend using multiple standard size room fans ranging from 50" to 58" each. Powerful motors with high airflow (CFM's) are important. Ultimately, the right size fan for a room is not determined by the size of the room alone. You must also consider the layout of the room, where the fan will be positioned in relation to the area where the airflow is most needed as well as how high the ceiling is.
