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.
If ceiling height allows, install the fan 8 - 9 feet above the floor for optimal airflow. 1  Standard mounts come with a 3 â 5 inch downrod, which is the metal pipe that extends from the ceiling bracket to the top of the fan. Downrods are usually either 1/2 or 3/4-inch in diameter. Extended mounts can be used to hang the ceiling fan at the desired 8â 9 feet from the floor for tall ceiling heights. Downrods can be purchased from 6 inches (9 ft ceiling) to 120 inches (20 ft ceiling). Check with the manufacturer or sales associate to determine the right downrod length for you.
