Wind turbines range in size from tiny micro turbines to enormous utility scale power production facilities. Large turbines may have blades that are over 40 meters long - meaning the rotor diameter would be 80 meters long - the length of a football field! The commercial-scale turbines are often placed on 80 meter towers, so the tip of the blades might reach as high as 160 meters (525 feet) in the air.
Smaller home- or farm-sized turbines usually have a rotor diameter of up to 15 meters (50 feet) and can be placed on 30 to 40 meter towers.
