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.
Take the popular Fanimation ceiling fan The Huxley for example, which dimensions indicate the blades will be 18.75 inches from the ceiling with the downrod that is included (6 inches). This would mean on a 9 foot ceiling the blades would be 7 feet 5.25 inches from the floor.Now, if you wanted to maintain that 7 foot 5.25 inch blade height, but were installing it on a 12 foot ceiling, you would require an extra 3 feet or a 42 inch extension downrod.Basically, you can use the following mathematical formula to determine the downrod length you need.ow, if you wanted to maintain that 7 foot 5.25 inch blade height, but were installing it on a 12 foot ceiling, you would require an extra 3 feet or a 42 inch extension downrod.
