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.
A guideline for sizing ceiling fans has been determined by the American Lighting Association. 1  For rooms 75 square feet or smaller, your ceiling fan should be 36 inches or less in diameter.  For rooms between 75 and 144 square feet, your ceiling fan should have a diameter of 36 to 42 inches.
