Have you ever looked up at a ceiling fan on high speed and tried to follow one blade with your eyes or make it so you can see the individual blades? There's something mildly fascinating about that. The blades that you're starting at, along with the motor, are major determinants of how well air is circulated throughout the room. Both the number of blades and the pitch are important.

Knowing Blades

The first thing to know about blades is that, the less there are, the more circulation of air you will get. Most people think the opposite is true. In fact, four and five-bladed fans are the most popular sellers. You'll also want to determine the length you'll need. The longer the blade, the more air gets circulated over a larger area. In general, 52-inch fans push the air out and away from the fan making this size more appropriate for bigger rooms.

When it comes to blades, you'll need to look at the pitch, or degree. This is the angle at which the blades are tilted. Pitch runs between eight and 16 degrees. With a high pitch, more air will circulate at slow speeds than with a smaller pitch. In warm summer months, make sure the blades run counter clockwise in order to pull up hot air. In the winter, run your fan clockwise to pull down trapped warm air.

You'll also want to check out the quality of blades. If you want the best, go with seven-ply blades. These are furniture quality. Commonly, blades are made with multi-ply wood and have a photo finish. If your fan is going outdoors, opt for molded plastic.
