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.
The ceiling fan you install should be the right size for the room: 1  Rooms that measure about 75 square feet need a fan with a 29- to 36-inch blade diameter.2  For rooms measuring 76 to 144 square feet, choose a fan with a blade diameter of 36 to 42 inches.f you're installing a new electrical box, fasten it to a ceiling joist or a 2 x 4 wood brace between two ceiling joists. If there isn't a suitable joist or brace available, but you have access to the framing through the attic, add a brace that can support the fan.
