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.
Best Answer: The size of a ceiling fan as stated by ceiling fan manufactures is generally considered the overall diameter of the blade sweep which they call blade span. The best way to measure blade span is to measure from the center of the fan to the tip of one of the blades, which will give you the radius. Multiply that x 2 and you have the size or blade span of the fan. Measuring from blade tip to blade tip only works of the fan has an even number of blades. Since most fans nowadays have either 3 or 5 blades, the radius measurement is more often necessary.
