What Are The Standard Garage Door Sizes?

by KE JIAYI 25 Apr 2023 0 Comments

When it comes to deciding whether or not to install a double garage door or two single garage doors, there are a couple of things you should keep in mind. It's nice that cost isn't one of them because a double door costs almost as much as two single doors. Though you may have to pay charges for two automatic garage door openers if you decide on buying them. 

Your garage door makes a big difference in how your house looks from the outside. One of the advantages of two single doors is that they can help narrow the space and add some visual harmony. By reducing the airflow into the garage every time it's opened, a single door can also reduce energy costs.

If you are planning to replace your garage door or add a new garage door to your home, it is vital to know the standard garage door size before buying the door. There are a number of different dimension combinations when it comes to garage doors, so it can be hard to define one specific size as a standard garage door size, but there are some sizes that are definitely more common than others. 

Your garage's size can have a significant impact on which type of door will work best for it in the long run. In order for a garage to accommodate two single doors, you need a wider garage (around 22 feet), whereas a double door can be installed in a garage that is smaller (18 feet). The additional space provided by a double garage door ensures that in case of a need to get into or out of the car, as well as the ability to accommodate an oversized vehicle. If you want two single doors AND a large car, consider extending each door to 9-by-8 to give yourself plenty of room.

Standard Sizes of Single Garage Doors

When you have a standard one-car garage, you will have enough room for a sedan or SUV to park. There may be separate garage doors for each opening of a two-car garage. Single garage doors typically open eight or nine feet wide and seven to eight feet high.

The standard garage door opening size isn't big enough for old garage doors. The size of houses has increased over the years, though. The garage door has also grown nine feet wide or more with this increase. Since cars keep getting bigger, garage doors have stayed the same height.

Standard Size of Double Garage Doors

Depending on how many garage bays you have, there may be two separate garage doors. Double garage doors make it much easier to park two cars in a garage. Additionally, you could park more than one car in your garage to protect more vehicles.

There is a standard size and height for double garage doors, which are 16 feet wide and 7 to 8 feet tall. In a garage with a double door, large cars can be parked with ample mirror space. The option is also popular for people who plan on using part of their garage as a workshop. 

Can I Change the Size of My Garage Door?

You just got a bigger car or an extra one? Are you having trouble parking your new SUV or van in your garage? Two cars could make it hard to get in and out of your garage, so you might have to increase the size of your garage door. 

Garage doors can be increased in height and width pretty quickly. In order to increase the dimensions of your garage door, we recommend you leave it to the experts. 

Before doing anything else, you should check the design requirements for your garage, and engineers will be able to help during this initial phase.

Keep in mind these important points. 

  • Garage door expansion might require a few specialists since it involves external cladding, internal cladding, supporting structures, and moving electrical points. 
  • Seeing if the garage is big enough for expansion is important. There has to be room for the garage door motor and enough space for it to open. 
  • The best way to increase the size of your garage doors is to change the load-bearing structural elements in your garage. These include the side posts and crossbars, as well as the support pillars on either side of the garage door. In order to avoid compromising the structural integrity of the building, these elements have to be considered. Garages under residential buildings are especially important. Whether it's possible to dismantle the outer cladding should also be considered. 
  • The garage door may need to be replaced once the increase is done. You may also have a problem with a weak motor handling the heavier, newer door. 

Suggestions for You

The width, height, internal headroom, and internal reveal of your garage have to be measured properly. You should rely on an experienced, qualified fitter for this, as they will also be able to explain your options clearly. A garage door's specifications vary, so you need to consider all these factors before ordering. 

Consider these things before buying garage doors: Are you having difficulty passing your car through the garage door opening, or do you intend to get a new car? 

When selecting single or double garage doors, it’s important to take into account energy efficiency, convenience, and aesthetics. Ultimately, the choice is a personal one, and you should choose the option that best fits your needs and budget.

Final Thoughts

When purchasing a garage door, it is important to measure the opening of your garage in order to get the right size. You will also need to measure the height of the opening, as this will determine the height of the door you need to order.

What is Lorem Ipsum? Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. Why do we use it? It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
