Downrods range in diameter and length depending on the ceiling fan type and application. Standard ceiling fans include a downrod ranging in length from 3 inches to 6 inches, which is suitable for standard size rooms with a ceiling height of 8 â 9 feet.or example, if your ceiling is 10 feet in height and your ceiling fan is 12 inches in height, you will need a 1-foot downrod to mount the ceiling fan 8 feet above the floor.
A ceiling fan with a minimum blade span of 56 inches and a CFM rating of 5500 or higher is sufficient for a 23' x 17' room (or 390 square feet). However, if you want to install two ceiling fans, we recommend choosing two fans designed for half of the room size.
