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.
Use the room's square footage to determine the proper size for your ceiling fan. Here are some general recommendations: up to 75 square feet: fan size of 29 to 36 inches. 76 to 144 square feet: fan size of 36 to 42 inches. 144 to 225 square feet: fan size of 44 inches. 225 to 400 square feet: fan size of 50 to 54 inches. over 400 square feet: use multiple ceiling fans following the above sizes. For instance, if you have an 800 s.f. room, you would need two 54-inch fans.
