What Size Garage Door Opener For A Double Door?
For most residential garages, the recommended opener size for a double garage door is:
½ horsepower (HP) to ¾ horsepower (HP)

Most experts recommend ¾ HP openers for double doors because they provide better performance and durability.
Why Double Garage Doors Require Stronger Openers
Double garage doors typically measure:
- 16 feet wide
- 7–8 feet tall
Because of their larger size, they weigh significantly more than single garage doors.
The garage door opener motor performs several important tasks:
- Lifting the door along the track system
- Controlling the opening and closing motion
- Maintaining consistent movement
If the motor is underpowered, it may:
- strain during operation
- wear out faster
- struggle to open the door smoothly
