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.
Large living rooms, great rooms. Most fan manufacturers produce fans that span 60 inches or more. As fans get large, they will have longer, heavier fan blades. 60-inch (or larger) fans can circulate air over a very large area, but they do it slower. For maximum efficiency, your ceiling fan should be placed as close to the center of the room as possible. The tips of the fan blades should be at least 18 inches away from any wall. If the size of your room exceeds 20 feet, consider using multiple fans to ensure that the entire room gets a good breeze. Keep in mind, that not all ceiling fans are created equal.
