Ceiling fan mount and downrod by ceiling height — flush at 8 ft, downrod above
An 8-ft ceiling gets a flush mount; taller ceilings use a downrod of (height − 9) × 12 + 6 in. to land blades 8–9 ft up.
What this diagram shows
Two room sections. An 8-foot ceiling uses a flush (hugger) mount that keeps the blades about 7.5 feet off the floor. A 12-foot ceiling drops the fan on a downrod calculated as ceiling height minus 9, times 12, plus 6 inches (42 inches here), landing the blades in a shaded 8-to-9-foot comfort band. Each section dimensions the blade height off the floor.
