If you’re looking for the best ceiling fan for your room, you need to know how to measure it properly. The blade span, CFM rating, Room square footage and height are all factors that you’ll need to consider. To be sure you buy the right size, you’ll want to measure the room from top to bottom.

CFM rating

When choosing a ceiling fan, it is important to consider the CFM rating. The higher the CFM, the more powerful the fan will be. It can also help you determine the fan’s efficiency. All ceiling fans manufactured in the United States are tested to determine how efficient they are.

A ceiling fan’s CFM rating tells you how much air it can move per minute. Higher CFMs will move more air per minute than lower ones. CFM is a better measurement than RPM for fans. This metric automatically considers the pitch, length, and number of blades in order to calculate the airflow rate. The stronger the breeze, the higher the CFM rating.

Area square footage

If you want to buy a ceiling fan, you must first determine how much square footage you have in your room. This measurement is easily done by multiplying the length and width of the room. A room measuring 10 x 12 ft by 12 ft has 120 square feet. You can also divide a room into sections of equal size to determine its square footage. For example, an L-shaped room has two sections of equal size, one of which should have a measurement of 120 square feet. Add the square footage from both sections together to get the total area.

Once you’ve determined the square footage of your room, the next step is to determine the appropriate ceiling fan size. You will need a tape measure, a pen or piece of paper, and a pencil to do this. You can also use your smartphone to measure the space. To calculate the total square footage of the room, divide the measurements by four.

Height

There are two ways to measure the span of a ceiling fan. The first method is to measure the distance from the center of the fan to the tip of one of the blades. Then, multiply the distance by two to get the diameter. If you have even blades, measure the length of one blade tip to its opposite tip.

The other method is to measure the height of the ceiling of the room. A low ceiling can cause the fan to fall on the head of someone standing on it, so you should measure the height of the ceiling to accommodate it. A ceiling that is lower than eight feet will not allow the fan to circulate air as effectively. A low-ceiling room can be cooled by a fan with a low profile. However, a hugger fan will work well in a high-ceiling area.

Blade diameter

When buying a ceiling fan, one of the most important measurements is the blade diameter. This is the diameter of the imaginary circle that the blades will form when they are spinning. The blade diameter will vary depending on the type and make of fan you are buying. The larger the blade diameter, the more air the fan can circulate in a room.

When purchasing a ceiling fan, it is important to measure the blade diameter and length. The length of each blade should match the length of the room. You can use a sizing chart to make sure that the blade diameter is appropriate for the room.
