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.
More importantly, though, you'll need to choose the right size ceiling fan, according to the size of the room. Ceiling fans come in a variety of sizes ranging from 30 inches for small rooms to 70 inches for larger rooms. Fans that measure 52 inches are the most commonly used.
