The biggest turbines at the moment have blades over 50 metres long. The rotor diameter is then over 100 metres long, longer than a football field. Smaller home, or farm, turbines have blades up to 15 metres (50 feet). The blade length varies depending on output. Typical commercial wind turbines generating around 600kw have blades of 20m. you can find the approximate length of blades for your turbine if you know the required turbine output. L=( P/(Cp*0.5*density*pi*(wind velocity^3)))^0.5 value of Cp < 0.59. usually for good turbines 0.45

Per four hours worked, break times usually last between five and twenty minutes
