Choose The Right Ceiling Fan Size According To The Room Size
Today, ceiling fans come in a wide range of options, but one has to consider a few things for purchasing the perfect ceiling fan for his/her home or office. It is essential to consider the blade span, ceiling type and height, and room size before buying a ceiling fan. Only then can you choose the right fan size to optimize the fan’s efficiency in a given space.
Installing the ceiling fan most appropriate for your room size will help ensure that you maximise your air flow. Once the room size is determined, you can choose a fan that will go with the decor of the room in question. For instance, a ceiling fan for the living room will be much longer in blade diameter than a kitchen ceiling fan. Here is a ceiling fan size chart according to the room size:
|Blade Span||Good for||Room Size|
|29″ to 36″||Bathrooms, Breakfast Nooks, Utility Rooms||Up to 75 sq. ft|
|42″ to 48″||Bedrooms, Kitchens, Dining Rooms||Up to 175 sq. ft|
|52″ to 56″||Large Bedrooms, Family Rooms, Media Rooms||Up to 350 sq. ft|
|60″ or larger||Great Rooms, Other Large Spaces||More than 350 sq. ft|
Length Of Downrod And Ceiling Height
Ceiling height is the height between the floor of the room and its ceiling. There is a variety of ceiling fans that one can choose from according to the ceiling height. The ideal fan height from floor to fan blades is approximately 8 feet. If you hang a ceiling fan too high or too low, it can affect the efficiency of the fan. Not only will it result in a reduced airflow in a room, but your ceiling fan will also consume more power while trying to push hard.
The most commonly used method to find the right downrod length is to take the ceiling height and subtract the height of the ceiling fan from it. After this, you subtract the ideal hanging height (usually 8 feet) from it. Here’s a length chart for selecting the proper downrod length:
|Ceiling Height||Pole Length|
|8 Feet||No Downrod|
|9 Feet||6 Inches|
|10 Feet||12 Inches|
|11 Feet||18 Inches|
|12 Feet||24 Inches|
|14 Feet||48 Inches|
|15 Feet or greater||60 Inches|
Recommended Blade Span
Ceiling fans are measured by the full size of their blade span, that is, the diameter of the circle that the fan blades make when in motion. So, for measuring the blade span of a ceiling fan, you measure one end of a blade to the end of another blade. Here is the chart for the recommended blade span according to the room size:
|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 longer||More than 350 sq. ft|
Ceiling Fan According To Height Of The Ceiling
To determine the best-suited ceiling fan for your home/office, you need to keep in mind the ceiling height and mounting options for the fans, such as close-to-ceiling, flush with the ceiling, extended from the ceiling, and a sloped ceiling.
- Close-to-Ceiling FansThis option is perfect for living rooms, bedrooms, or for any other room where the ceiling height is roughly 9 feet. Usually, a downrod of 3 to 5 inches is installed between the ceiling canopy and fan. The additional space thus created produces stronger air circulation.
- Hugger / Flush Mount Ceiling FansThis mount option is ideal for low ceilings (8 feet or shorter). There is hardly any space between the motor housing of the ceiling fan and the ceiling, thus, making it an ideal choice for smaller urban spaces, including apartments and condos.
- Extended From The CeilingRooms having high ceilings require longer downrods for maintaining the proper height of the ceiling fan. This option is best for conference rooms, lofts and expansive entryways with noticeably tall ceilings.
- Ceiling Fans On Sloped CeilingsIf a ceiling has any slope angled pitch, a sloped ceiling adapter is mandatory. Since not all ceiling fans are sloped ceiling adaptable, you need to check the details of the fan carefully. For sloped ceilings, most fans come with mounting hardware that will hang flat, or at an angle up to 30 degrees. But again, this varies from brand to brand.
Uses Of A Downrod And Why Do You Need One For Your Fan
A downrod is a metal pipe that connects the motor housing of the ceiling fan to the mounting hardware to stabilize the fan and reduce wobbling. It is sometimes required to achieve the correct distance between the fan blades to the ceiling. It positively affects the efficiency and amount of air it is capable of producing.
While choosing a downrod, consider the following:
- Interior Diameter – usually, downrods are available with 1/2-inch and 3/4-inch interior diameters. So, while purchasing a ceiling fan, make sure that the interior diameter of the downrod matches to that of your fan you have at home. It is best if you choose a downrod of the same brand as your ceiling fan.
- Finish – When you choose downrod of the same brand as your ceiling fan, it is the best match for the motor housing finish. You could also select from decorative downrod sleeves from the same brand to add to the ornamental aspect of your fan.
Fans For Small And Large Rooms
If the size of a room is 9′ x 9′ or smaller, the recommended blade span for small room ceiling fans ranges from 40″ to 48″. These fans are designed to provide good airflow in small bedrooms or office spaces. For rooms that are larger than 20′ x 20′, the recommended blade span for large room ceiling fans ranges from 60″ to 64″. These large ceiling fans are ideal for master bedrooms, spacious game rooms and living rooms, and rooms with high ceilings.
Ceiling Fan Blades
The size, number, and the blade pitch (angle of tilt) of the fan blades determine their performance and efficiency. Longer blades usually create more airflow than the smaller ones. A fan with longer blades will create more airflow than a fan with small blades, provided that the fan motor is of very good quality. But there is one factor that should be mentioned here – ‘drag’ factor. When the fan blades slice the air, they are met with an opposing force, a resistance which they have to overcome. This opposing force is what tends to slow down a ceiling fan’s motion. High performance motors make this an easy task for the blades.
Assembling And Installing Your Ceiling Fan
Although it is best to get your ceiling fan installed by a professional, you could also do it yourself with the help of this step-by-step guide.
- First, turn off the power on the circuit breaker.
- Detach whatever current fixture that you have (light bulbs, glass fitters, etc.), if any.
- Now, determine the strength of your junction box for this is what will hold your fan. If it is strong enough, mount the fan bracket to the junction box.
- Attach the downrod and the fan blades to the motor and hang it onto the mounting bracket.
- In case your fan model has a receiver module, install the receiver module into the mounting assembly. If there is no receiver module, you can connect the house electrical wires to the fan electrical wires.
Installing A Light Kit On The Ceiling Fan
- First, cut off the power supply to the fan from the main panel.
- Check if the fan has a housing assembly at its centre because you can install a light kit only when it is present.
- Unscrew the centre plate of the fan to expose the wiring.
- Check if your fan has a wire solely dedicated to add a light kit. Usually, it has a visible label on it. You will come across two wires: a white (neutral) one and a black (power) one.
- Carefully put white and black wires of the light fixture through the hole in the centre plate. Now align the matching wires parallel to one another and screw on a corresponding wire nut to each set: white to white and black to black.
- Firmly screw the light assembly onto the centre plate of the fan.
- Now attach the centre plate to the fan housing and install light bulbs, or shades, or pull chains according to your wish.
