What size generator do I need for my home backup power requirements?

To choose a properly sized generator, add up the wattage of all appliances you intend to run simultaneously (amps x volts = watts). Then select a generator rated at least 1.5x that total to cover startup (surge) loads. Never overload your generator, as that can damage both the generator and connected devices.
