A ½ HP motor certainly enough for doors in the 8 ft. to 12 ft. (2.4 to 3.7 m) wide range. Use a ¾ HP motor for doors measuring over 14 ft. (4.3 m).
Keep in mind that an electric garage door opener is only meant to work as a substitute for human strength. Therefore, the door must be well-balanced at all times in order to maintain its dead weight at 8 to 10 lb.
(3.5 to 4.5 kg).
