The help of technology when it comes to the heavy garage doors opening is beneficial. Nowadays, you can find several types of garage doors openers, according to the HP (horsepower) they have.

  • 1/3 HP – This garage door opener is suitable for light, single garage doors, which you will be able to lift manually. It is not an expensive option, but this opener won’t last long if you have a wood door.
  • 1/2 HP – This garage door opener can lift both single and double regular size garage doors.
  • 3/4 HP – This garage door opener will manage to open heavier doors. They are long-lasting and stable, but their price is higher. However, if you have a natural wooden door that can sometimes gain weight due to absorbing humidity, the strength this model provides is necessary.
  • 1 HP – This garage door opener is an excellent option if your doors are heavy and more than 16 feet (4.9 m) wide.

The motor on a garage opener can use both AC and DC. However, the DC ones are more effective, don’t produce that much noise, and are usually smaller and lighter.

The Size of Garage Door Opener

Since garage door openers is basically a motor, it is rated with HP (horsepower). In theory, a garage door opener rated with 1/2 HP should lift about 185 pounds (84 kg), while a 3/4 HP opener should lift more than 370 pounds (168 kg).

Unfortunately, it is entirely different in practice. The reason is that manufacturers base the ratings of openers on maximum output without calculating built-in safeguards on newer models.

Door weight

Horsepower rating

0 to 125 pounds (up to 57 kg)

1/3 HP (0.25 KW)

0 to 300 pounds (up to 136 kg)

1/2 HP (0.37 KW)
0 to 500 pounds (up to 227 kg)

3/4 HP (0.56 KW)

0 to 650 pounds (up to 295 kg)

1 HP (0.75 KW)

Therefore, the most common 1/2 HP garage door opener will probably lift less than 125 pounds (57 kg). In other words, you can buy this model if your garage doors are 8 to 12 feet (2.4 to 3.6 m) wide.

When you have heavier, over 14 feet (4.3 m) wide garage doors, you should use the 3/4 HP opener. This model can lift approximately 275 pounds (125 kg).

Keep in mind that these numbers are not 100% precise and depend on the age of the garage door opener and its production date. Plus, some of them contain nylon gears and excessive force auto-shutoff that stop working under the action of excessive force.

  • Side-hinged doors – It is a traditional type of door with two wings that open simultaneously.
  • Canopy and retractable garage doors – The difference between these two types is that canopy doors slide up over vertical track and form a canopy. The retractable door slides up over a horizontal track on the ceiling, moving inside the garage.
