How to Choose a Ceiling Fan? (Size, Blades and Airflow)

Some jobs like picking the perfect ceiling fan for your house or the right size of the ceiling fan for your room can be slightly annoying. You do not, however, need to be concerned about this.

It might seem challenging to select the perfect ceiling fan according to your choices, and you might not like the fan you got if you don’t know how to pick it.

When purchasing a ceiling fan, there are several factors to consider. Your room dimensions, fan size, CFM, and airflow are some of the essential things that you should consider before getting a fan.

Here’s a step-by-step guide to selecting a ceiling fan for your home.

 

How do you determine the right ceiling fan size for your room?

How do you determine the right ceiling fan size for your room

The size of your space is the most important factor to consider when purchasing a ceiling fan. You can easily decide how big or small your fan should be by considering the square footage of your room. 

You may easily record the circumference of your ceiling fan’s blade sweep if you do not really understand how to estimate its size. It’s as simple as comparing the tip of one blade to the tip of the next blade across the room. 

If your ceiling fan has an uneven number of blades, measure each one from the centre to the tip.

After that, you can double the measurement. After you’re done measuring the size of your fan, you can now proceed to measure your room dimensions.

 

Fan Size Room Size Room Type
29” or less Less than 50 sq. ft.  Hallway, Laundry, Room, Walk-in Closet
36” Upto 75 sq. ft. Breakfast Nook, Large Bathroom
42” Upto 100 sq. ft. Bedroom, Office, Kitchen
52” Upto 225 sq. ft. Master Bedroom, Dining Room, Patio Area
56” Upto 400 sq. ft. Large Living Room, Great Room

 

If you have ample space and do not know which fan to choose, you can quickly go for 2 small fans. When sizing a ceiling fan, make sure there is 18 to 24 inches of space on all sides of the fan.

 

How do you calculate the fan’s hanging height?

How do you calculate the fan's hanging height

Building codes require hanging a fan at least 7 feet above the floor. If you choose to hang it about 8 to 9 feet above the floor, optimal circulation will allow. You can attach the fans with downrods for higher ceilings, like a ball ceiling fan for achieving the accurate height. 

Better airflow and circulation can be achieved, considering the more space there is between the roof and your fan blades. 12 inches is an ideal length space.

1. Low Ceilings: 

If your room ceilings are shorter than 8 feet, you can use flush mount fans. They are the ideal option. 

These fans do not lay hanging; instead, they are very close to the ceiling. This occurs because flush mount fans are not designed with downrods.

 

2. Average and High Ceilings:

If your ceiling is above 9 feet or higher, then a fan uses downrods so that it fits right. 3 to 72 inches is the range of a downrod. This is recommended as there is sufficient space between the fan blades in the ceiling. This results in better circulation of air.

The packaging of fans includes 1 or 2 downrods that come in different lengths. If you need a longer downrod, you can easily find it in the market.

 

Can you install a ceiling fan if you have a sloped ceiling?

Can you install a ceiling fan if you have a sloped ceiling

If your slope is up to 30°, more giant fans can easily accommodate. However, longer downrods might be required to achieve sufficient air circulation. 

However, if your slope is steeper and not allowed to install a ceiling fan, you can easily use angle mounts that are sloped ceiling adapters. 

 

Do you need a particular ceiling or junction box to mount your fan?

There are certain junction boxes that can be used for mounting your fan since it is necessary. 

The weight of your fan can be up to 50 pounds, which is why they require proper support. You need to anchor a ceiling joist to the boxes installed by an electrician for proper functioning.

 

Can your fan also light your room?

There are certain fans available that can help in lighting up your room. They come with inbuilt light kits that help in ambient illumination. You can find ceiling fans in both the options, one with lights and the other without.

 

Can you use a ceiling fan outdoors?

You can easily make use of ceiling fans outdoors. All you have to do is make sure it’s approved for damp or wet locations. Fans for damp locations can be utilised in enclosed places where they do not come into direct contact with water.

However, you can use wet location fans anywhere as they are susceptible to water. These fans are specially built for water and weather resistance, so they do not stop working after a storm.

 

How does a ceiling fan work?

Rotating pitched blades help the ceiling fan to work. The pitched blades allow airflow, which provides better air circulation. You can only feel the air on your body if the fan is in motion. 

Ceiling fans also circulate the cool or hot air produced by an AC or heater. Other factors like the size of your ceiling fan and the size of your room also play a significant role.

 

How can you control the fan?

How can you control the fan

Pull chain, handheld remotes, or wall control are various techniques for operating a fan.

1. Pull Chain:

These chains are located on the fan and allow you to maintain the speed or turn the fan on and off.

 

2. Remote:

Handheld remotes are highly useful since they allow you to control your ceiling fan from any location within a certain perimeter.

 

3. Wall Control:

You won’t have to worry about losing your remote if you get a wall control mounted.

You can easily walk up to the wall control and control the settings of your fan. You can turn the fan on and off, regulate its speed, and turn the lights in the fan on and off.

Some types of fans are available that come with two or more controlling options. 

 

What is CFM and Ceiling Fan Airflow? 

CFM stands for cubic feet per minute, while airflow describes how much air your fan can move. Airflow is measured in CFM. When your fan is at the highest speed, that is when CFM measurements take place. 

Watts are used to divide CFM. Higher CFM results in better fan quality and airflow. 70 CFM/W is required to consider the fan as efficient.

You can easily compare fans based on CFM. Your fans, on the other hand, should all be the same size. This is how you can tell if your fan is working properly.

  • Good CFM should be between 4000 and 5000.
  • CFM varies from 5000 to 6000 for better performance.
  • Over 6000 CFM is the best CFM.

 

What is a DC Motor Ceiling Fan, and what are the advantages of using one?

What is a DC motor ceiling fan, and what are the advantages of using one

Less than 70% of electricity is consumed by a DC motor ceiling fan compared to any other standard ceiling fan. 

A DC motor transforms electrical energy into mechanical energy. DC motor ceiling fans are considered more expensive than any other fans because they use higher quality motors. Several benefits are offered by DC motor ceiling fans. They are –

  • Silent virtual operation
  • Small motors resulting in smaller and lighter fans
  • Efficient energy is used to prolong the life span of your fan.
  • Higher talk results in a faster start of speed
  • Possibility for up to 6 different speeds

 

What should you consider while picking a Ceiling Fan Blade?

It’s critical to think about how many fan blades a ceiling fan has. However, nowadays, it is not about the technology but about the aesthetics that please your mindset.

The number of blades is solely for aesthetic purposes. In early times, a fan with more blades would be considered more efficient than a fan with fewer blades. Although, in recent times, CFM has determined the efficiency of a ceiling fan.

 

What effect do different blade coatings have on their performance?

Four significant materials are used for making ceiling fan blades. Different materials offer different functions. This is why you should think about the type of coating you want for the blades of your ceiling fan.

1. MDF:

MDF stands for medium-density fibreboard. Blades, sawdust, and other word remnants are compressed together to form MDF. After the blades are made from MDF, they are laminated to give them a finished look. 

These blades are pretty affordable and are used in cheap fans; however, that is not always the case. MDF material is not suited for the outdoors as they start looking droopy soon after installation. 

Although, if you are installing these fans in an indoor location, then they can work perfectly.

 

2. Plastic:

There are several fans in which manufacturers use ABS plastic since it is inexpensive and cheap. The best part about plastic is that it can hold any shape and, after finishing, can even look like wood

You can install fans made of ABS plastic outdoors too. You can efficiently finish ABS blades using 2 different laminates. Just like MDF, ABS blades can also be reversible.

 

3. Wood:

Wood is considered one of the best options for indoor fans. However, you can easily install wooden fans outdoors as well. They can easily survive in damp weather but not wet weather. 

Since it takes more resources and work to make wooden fans, they are more expensive than conventional fans. These blades are made of natural wood and are considered premium. 

The wood used to make wooden fans is lightweight and aerodynamic. These fans also have a thicker profile than other fans.

 

4. Metal:

Metal fans are the ideal option for larger rooms. However, you cannot hang a metal fan below 10 feet from the ceiling. Metal fans can be used both inside and outside.

Portable fans and oscillating ceiling fans also use metal blades. However, these fans can become rusty outdoors. Although, a protective cage is installed along with the metal fan so that everything is safe.

 

FAQs

1. Is a 3 blade fan better or a 5 blade fan?

Earlier, the more blades the fan had, the better it used to circulate air. However, nowadays, all the fans produce sufficient airflow, and the number of blades is just for personal preference.

 

2. What happens if your ceiling fan is too big?

If your ceiling fan isn’t equal to the size of the space, it can be harmful. A larger ceiling fan can easily injure you if you get into contact with it.
