For larger turbines, such as those used in offshore wind farms, the blades are significantly larger and heavier. These blades can weigh between 20,000 pounds (9,072 kg) and 30,000 pounds (13,607 kg) or more, with lengths extending up to 150 feet (46 meters). Thickness: The thickness of the blade varies, being thicker at the root (the base of the blade where it attaches to the. . A medium-sized Rampion, and the Bard VM, the world's largest wind turbine (to date). In contrast, home wind turbines are comparatively lightweight. Rotor mass trends are complicated by material solutions, aerofoil choice, and design tip speed, which directly impact the solidity and mass of a blade. The introduction. .
