How To Know The Right Ceiling Fan Size

The first thing you should do is determine your bedroom's square footage. Knowing how big it is, you can estimate the measurement of any furniture or fixtures you will buy. Measure it by multiplying the total length by its width.

Look at the example below for better understanding:

  • Length in feet x Width in feet = Total floor area in square feet

For example, the total length of your room is 10 feet long and 10 feet wide. So, 10 feet x 10 feet = 100 square feet

After that, check out the quick guide to sizing ceiling fans based on the image below:

When dealing with larger and longer dimensions, Add two or more smaller separate fans. Make sure to have at least 8 inches of clearance between the blades to prevent them from bumping with each other.

Be keen about this because it will help your appliance a lot. Installing a big ceiling fan in a small room may blow the air too powerfully while having a small fan in a big room will lead to the motor potentially overheating from overworking to keep the space cool.

How High Should You Hang Your Fan?

Ceiling fans should at least be 8 feet above the floor, and the blades should have a minimum of 18 inches of distance from the wall. If the ceiling height is less than 8 feet, choose a low-profile ceiling fan.

Nowadays, it comes in different styles that will suit a homeowner's taste, like the photo below.

But if it is more than 9 feet long, opt for the one with a downrod.

It can lower your fan to give the best cooling effect and helps stabilize it to prevent it from wobbling when turned on. This comes in different lengths depending on the height of your ceiling.

What Downrod Size Do You Need?

To make sure you got the correct measurement, calculate the length of downrod you need by referring to the following formula:

Ceiling Height - 8 feet (standard distance above the floor) = Downward Length

Let's say you have an 11 feet ceiling; using the equation above: 11 feet ceiling - 8 feet = 3 feet (36 inches)

Now, you can calculate your needed downrod length on your own. Do not worry if you have a sloped or angled ceiling. There are available bases for that to keep it straight, like what you can see in the photo.

How Many Blades On A Ceiling Fan Is Best?

The best ceiling fan blade will depend on your needs. Whether you are after the aesthetic, the money you'll save, or the level of performance. Ceiling fans can have up to eight blades, but the most common among the buyers on the market are the 3-, 4-, and 5-bladed ceiling fans.


This type is the most money saver among the rest. Three blades are lightweight, so they require less energy. Meaning, you pay less for the electrical bill. The downfall is producing more sound because it uses an uneven number of wings to balance.

They are often used in industrial places like the office and public spots where noise is not an issue and is the last thing they will care about.    


The opposite of a 3-blade, the 4-bladed ceiling fan is quieter due to the added weight. But since it's heavier, it consumes more electricity to be able to rotate them. It also costs more, but this is the ideal indoor ceiling fan.

Perfect for bedrooms where you need a quiet night since additional blades produce gentler wind.


The only reason a homeowner would purchase this is for personal taste. As discussed above, the heavier the blades, the heavier they will become, which means: more energy consumption and price and less noise.

According to research, curved and straight fans differ in produced noise and performance. A straight fan blade moves more air while curved blades create less noise.

  • Performance: Straight fan blades stall at a higher pressure, enabling them to circulate a stronger breeze than curved ones. If you opt for maximum performance to fight the heat, straight blades are for you.
  • Noise: Curved blades blow weaker, which makes it not that noisy. Noise-sensitive people can make this a good choice if they are after the silence.
