What Are The Standard Garage Door Sizes?

by KE JIAYI 20 Jun 2023 0 Comments

If you are building a new home or garage, then consider the standard garage door size because it is an important factor to know the standard garage door size, style, operating mechanism, and different dimensions of door sizes.

So, if you are looking for trustworthy information about standard garage door sizes, then here you will find out everything you need to know about standard garage door sizes.

You might be surprised to know there's no such thing as one-size-fits-all when it comes to garage doors. There is a range of 'standard' garage door sizes available in the market and to choose the right, you should know the exact dimensions of your garage door opening.

Standard Size(ft')
Width Height Size
4 21 4x21
7 16 7x16
8 7, 8, 16 8x7, 8x8, 8x16
9 7, 8, 9 9x7, 9x8, 9x9
10 7, 9, 10, 12 10x7, 10x9, 10x10, 10x12
12 7 12x7
16 7, 8 16x7, 16x8
18 18 18x18
24 8 24x8

Standard Garage Door Sizes

The standard garage door sizes may vary depending on your lifestyle, custom homebuilding or design, and even the purpose of your garage usage may cause a change in your garage door size. For instance, the door size will vary if you use your garage for trucks, large SUVs, or motorcycles.

However, the ideal standard garage door size is

  • The dimensions should be 9 feet wide by 7 feet tall or 8 feet by 7 feet broad for single-car garage door. A double garage door standard size is 16 feet by 7 feet.
  • The standard garage door size is taller with 9 by 8 single doors and 16 by 8 double doors in customized designs. In Florida, 10-foot garage doors are actually rather common for custom homes.

Standard Sizes Of Single Garage Doors

 Typically, the standard size of a single garage door is 7x6 feet 6 inches.  

Remember, for any regular residential place, these specifications (7x6 feet 6 inches) are the 'normal' garage door dimensions that are frequently employed by developers and independent builders. If you are considering a large garage door for your home, then you need to get a single large garage door to fit into a large opening.  However, it is difficult to fit the new large garage door appropriately by reconstructing the existing garage door space.

 Standard Size Of Double Garage Doors

Typically, the ideal double garage door size is 14 x 7 feet or 16 x 7 feet. Two automobiles can fit side-by-side inside double garage doors because of their normal width of 14 x 7 feet or 16 x 7 feet. Remember that you'll need adequate room around the automobiles to keep them safe and extend the doors open without running into other objects if you're creating a garage from scratch.

Size Of A Two-Car Garage Door

Most houses with multiple-car garages will have double doors, which are typically 7 or 8 feet tall and 16 or 18 feet wide. People who want to use their garage portion as a workshop or storage area frequently choose this option.

Dimensions Of An RV Garage Door

For individuals with exceptional requirements, such as parking several vehicles or an RV, large doors are available. These enormous garage doors are typically 10, 12, or 14 feet wide and tall.

The Standard Thickness Of Garage Doors

The standard garage door thickness is about 1/8 inch.  Insulation might or might not be necessary depending on how you use your garage. Install insulation if you spend enough time in your garage. Furthermore, for lowering energy expenses, well-placed insulation can warm your garage 12 degrees in the winter and cooler in the summer at approximately 25 degrees.

Is it Manageable To Change The Size Of My Garage Door?

Certainly yes! You can change the size of your garage door, but for this, you need to consider the opening structure of your garage, garage function, and consider your lifestyle while changing the garage door size.  So, the best way to discuss with your builder, discuss every possible alternative and cost as well.  A complete custom door might be the easier solution for replacing the garage door size.

To further enhance the drive-through clearance, one alternative is to install the frame behind the brickwork.

However, to change your garage door size, first measure your garage door carefully, for instance:

  • Measure the width & height of the door opening, also known as a "rough opening."  It is the closest inch and will resemble the same size as your door.
  • Secondly, you need to measure the space to the left and right of the opening (called the side room). 3.75 inches on each side are typically required for vertical track systems while some additional room is needed by some systems, measuring 5.5 inches. 
  • Then you need to measure the headroom, the distance between the opening and ceiling.
  • Lastly, calculate the backroom distance, which is the distance between the opening of the garage door and the wall behind the garage.  Important Considerations For Garage Door Sizes

Do big garage doors always make sense? Larger garage doors have additional practical considerations, although that depends. A door's measurements can also be stretched out, which can alter the way it looks and make the style you originally choose look different from what you see in the brochure.

Reliable Suggestions For You

Don’t measure your garage dimensions by yourself:

You must accurately measure every measurement of your garage, including the width, height, interior headroom, and inside reveals. It is strongly suggested you rely on the knowledge of a skilled, experienced fitter to complete this task effectively because they will also provide you wise advice regarding your options. Additionally, different garage doors call for various specifications, so all of these factors must be considered before placing an order.

Considering your current garage:

Think about your current garage door sizes, the difficulties you are facing, and the reason that compels you to change the door size. For instance, consider the factor that how you face trouble while getting your car in to fit properly through the current garage door.

 The Bottom Line

 Briefly, garage door size is an important factor to consider before placing your order for a door. The standard garage door size depends on the garage size, your residential property (house, business, or office), and your lifestyle.  So, consider garage door dimensions, operating mechanism, function, or purpose of your single or double garage door.

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).
