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.ey Ann! a 52 ceiling fan should be fine for that size room, but we wouldn't suggest going much bigger than that since the recommended size ceiling fan for that size room is 50 inches.
