What Size Garage Door Opener Do I Need

Choosing the right size garage door opener is crucial in ensuring that your garage door operates efficiently and safely. The size of your garage door opener depends on the size, weight, and type of machinery required to operate your garage door. In accordance with the two most common types of garage doors—two-car and three-car—here is the recommended size for a garage door opener.

Garage Door Openers for 2-Car Garage Doors

Two-car garage doors are the most common type found in residential properties. Chain drive, belt drive, or screw drive are the available types of garage door openers for two-car garage doors.

Standard Sizes

Here are some standard sizes for two-car garage doors:

12 x 7 feet

14 x 7 feet

16 x 7 feet

18 x 7 feet

The recommended horsepower for a two-car garage door opener ranges from 1/2 to 3/4 horsepower. A lower horsepower model may not be able to handle heavier doors or frequent use. However, if you have a lightweight aluminum or fiberglass door and don’t use it frequently, then a smaller motor may suffice.

Garage Door Openers for 3-Car Garage Doors

Although less frequent than two-car garages, three-car garages are nonetheless typical in many bigger homes. Due to the bigger size and weight of the three-car garage door, you should think about getting an opener with more horsepower. 

Standard Sizes

Here are some standard sizes for three-car garage doors:



The recommended horsepower range for three-car garages is between one and one-and-a-half horsepower (HP). This range provides enough power to lift heavy wooden or insulated steel doors while also providing smooth operation.

Factors Affecting Garage Door Opener Size

Aside from the size of your garage door, other factors can affect what size of opener you need. For instance, if you reside in a location that has strong winds or heavy snowfall, you might need an automatic lock system that offers more security and stability during severe weather.

Also, you may want to think about obtaining a quieter-operating opener if you intend to use your garage as a workstation or storage space in order to avoid disturbing your work.
