So, What Size Ceiling Fan For Outdoor Patio?
Before finding the best outdoor ceiling fans, you should first measure your room’s square feet. Secondly, it’s important to note that outdoor ceiling fans are bigger than indoor ceiling fans.
Why are outdoor ceiling fans bigger? I will explain.
In an enclosed room, air circulates, adding chilling effects faster. On the other hand, circulation spreads out in an open area, requiring a powerful motor for chilling effects.
If the same fan is used in outdoor and indoor cooling, it will cool a smaller outdoor area compared to indoor.
Read the table below to understand the recommended fan sizes for the patio.
|Floor Area in Square Feet||Fan Size in inches (Blade Span)|
|100 square feet||52 inches|
|101-225 square feet||60 inches|
|226-400 square feet||72 inches|
|401-625 square feet||84 inches|
|More than 625 square feet||Use multiple powerful fans|
If you missed it, the blade span is the circle’s diameter swept by fan blade assembly parts. Blade span is measured from the center of the fan to the blade’s tip, which is the radius.
To get the entire blade span, you multiply the radius by two.
Comparison Between Indoor and Outdoor Ceiling Fan Sizes
If you decide to remove your indoor fan and install it on the patio roof for a party or any other occasion, the results will not be the same. I earlier pointed out that.
To understand clearly, read the table below to note the effects of normal circulation and circulation spreading out.
|Blade Span (Inches)||Maximum Indoor Space (Square feet)||Maximum outdoor Space (Square feet)|
|42 inches||144 square feet||49 square feet|
|52 inches||225 square feet||100 square feet|
|60 inches||400 square feet||225 square feet|
|72 inches||625 square feet||400 square feet|
|84 inches||900 square feet||625 square feet|
In the above table, you can learn that there is a vast difference in chilling effects when the same fan size is used indoors and outdoor.
For instance, a 52 inches fan cools an indoor area of 225 square feet. In contrast, if you need to cool the same size outdoor area, you need a 60 inches fan blade span_ A difference of 8 inches.
Additionally, a motor that would rotate a 60 inches fan needs to be more powerful than the motor used in 52 inches fan. In short, it’s more costly to cool outdoor areas than indoors.

Spacing Requirements for Outdoor Patio Ceiling Fan
The challenge doesn’t require only purchasing and installing the fan. You need to understand specific requirements to make them effective.
However, you need to understand a few terms before learning the spacing requirements.
- Wind Chilling Effect
The fan helps circulate air around your body to absorb its heat, and in the process, you feel calm. This is known as the wind chilling effect. Note that the fan doesn’t have to lower the room temperature to create a chilling effect.

- Airflow Vs. Wind Speed
Airflow is the amount of air moved by the fan blades. Understand that airflow moves in terms of cubic feet.
On the other hand, wind speed is the speed of the breeze created by the fan’s blades.
A bigger fan might move slowly but moves hundreds of cubic feet of air. But on the other hand, it can create low wind speed.
And on a smaller fan, it needs to rotate faster to create high wind speed and airflow.

The Spacing Requirements
1. Between the fan and the Ceiling
The fan pushes the air downwards, and the Space is occupied by the air above. If the fan is installed too close to the Ceiling, airflow can be obstructed. The minimum spacing requirement is at least 8 inches.
2. Between the floor and the fan
The fan doesn’t have to be too low or too high for better chilling effects. At least 8 feet spacing is recommendable.
3. Between fan blades and wall
Close proximity between the two obstructs the airflow. The fan blade tip should be at least 18 inches from the wall.
4. Between two fans
You should ensure that the fan blade tips are 36 inches from each other. This gives room for better airflow from both fans.
Ideally, you can adjust the fan locations to make them effective instead of installing one at the center.

The outdoor patio is more prone to weather, unlike the indoor living rooms. So, find a fan that meets the following requirements;
1. Special ABS plastic blades.
2. Galvanized tubular steel that has a powder paint finish to prevent corrosion.
3. A motor casing with a waterproof seal to prevent moisture.
How Many CFM Do I Need for Outdoor Patio?
The cubic feet per minute should be 3 to 4 times the patio area. You should also learn the best outdoor patio fan ideas to install them accurately.
A CFM of 5000 to 8000 is considered powerful for efficient airflow.
How Many Fans Do You Need for a Covered Patio?
Depending on the patio size and the installation guideline, you can install one fan.
Note that some patios may be covered with wire mesh which allows air just as the open patios. In this case, you need to follow the outdoor fan guideline.
So, what size ceiling fan for outdoor patio? The size depends on the patio area in square feet. You can choose to install two fans for a rectangular patio.
