Which horsepower rating is the most common for garage door openers?

The most common horsepower rating for garage door openers is 1/2 horsepower. This rating strikes a balance between power and efficiency, making it suitable for the majority of residential garage doors, which typically weigh between 150 to 300 pounds.

A 1/2 horsepower opener provides sufficient lifting power for standard garage doors made of common materials such as steel or wood, while still being energy-efficient. Openers with this power rating are generally adequate for both single and double doors found in many homes, ensuring reliable functionality without excessive energy consumption.

Other horsepower ratings like 1/4 horsepower may be too weak for most residential applications, while 3/4 horsepower and 1 horsepower options are more powerful than necessary for standard garage doors and may result in higher costs and energy use.
