Ceiling Fans: Selecting the Right Size

There are so many different types, sizes, and styles of ceiling fans to choose from. With so many things to consider before you purchase — how to choose the best ceiling fans size?
In this discussion, we will focus on selecting the right ceiling fan size for the room where the fan will go.

General Things to Know

Ceiling fans vary widely in price, but as with any consumer product, you get what you pay for. High-end fans, generally those priced at $300 or more, will come with high-quality motors that are very powerful. The blade pitch-angle on these better fans will be set at a steeper angle, because the motor can handle the resistance of the fan-blades taking a bigger bite out of the air. This means that quality fans with a smaller blade-diameter might actually move more air than low-quality fans with a larger diameter. This is because lower quality fans have less powerful motors, and the fan-blades, by necessity, must be set at a lower pitch-angle in order for the motor to be able to handle the air resistance. A lower blade pitch-angle means the fan-blades take a smaller bite out of the air. You will want to read reviews and manufacturer’s claims to determine the right fan model to suit your needs.

Know Your Room Size

Start by determining the square footage of the room where the fan will go. You do this by taking a tape measure and measuring the length and width of the room and multiplying the two numbers to give you the area of the room in square feet. Table 1 discusses the recommended fan sizes for the rooms in your house.

There are cases where two smaller fans might work better than one large fan. If you have a large rectangular room (more long than square) that is over 300 square feet, you may want to consider using two smaller (under 50″) fans instead of one big fan to circulate the air more evenly in the room.
