The main part of the fan to which all the blades attach measures 9.19 inches. With blades attached, the center of the fan to the edge of the blade is just under 14 inches, meaning the entire fan from one blade tip to the other is around 28 inches. The top part of the fan assembly that physically attaches to your ceiling measures in at 7.7 inches.
With the fan running and the light turned off, the ceiling fan uses approximately 75 watts of electricity. The fan uses two 60-watt bulbs, so you can approximate that with both light bulbs illuminated, electricity usage approaches closer to 200 watts. These calculations are for when the fan is set to the 'high' speed setting; electricity usage diminishes on lower speed settings.
Airflow in consumer products is generally calculated in terms of cubic feet per minute (cfm). Essentially, the amount in square feet of air that the fan can move in one minute. Cfm is an important and often overlooked factor in purchasing a ceiling fan. The cfm of the Hunter Retro Ceiling Fan is 5,932.
Airflow Efficiency compares the airflow of a fan the the electricity usage that airflow requires by dividing the airflow in cfm by the electricity usage in watts. This gives an approximation of the overall electrical efficiency of the fan. The airflow efficiency rating of the Hunter Retro is 79, a rating usually only seen in much larger fans.
