Why We Love Large Ceiling Fans. Big spaces need large ceiling fans if you want to get any real sense of air movement and these big fans can take care of that. If you want to be counted as a large ceiling fan, you will need a blade span (diameter) of at least 52 inches (over 4 feet) or more. Truly large ceiling fan designs get into the 6-foot and even 7-foot range and that means all the more refreshing air circulation for everyone.
As a general rule, ceiling fans use less wattage than box fans. A 42-inch ceiling fan on low speed uses only 24 watts of power. A 36-inch ceiling fan at high speed is still economical at 55 watts. A 52-inch ceiling fan on high speed supplies a tremendous amount of cooling power but only uses an affordable 90 watts of electricity.
