Although there are a few standard garage door sizes, homeowners have additional options thanks to the ever-expanding world of custom homebuilding and designing a garage that fits large SUVs, RVs, boats, trucks, and motorcycles. Therefore, we are going to talk about the standard garage door sizes in detail; please keep in touch to get a deep insight.

Garage Door Design Options:

The size and configuration of your garage itself will determine the appropriate garage door size. Garage designs range from compact areas intended for a single vehicle to larger, typical two-car garage door sizes to options for multiple vehicles.

If you purchased a pre-existing home, this choice was probably already made for you. But there are a number of things to take into account when building or remodeling a house, such as:

  • Numerous vehicles are based on individual tastes, preferences, and requirements.
  • Aesthetics and how the garage façade will impact your home's exterior.
  • The cost of upkeep for multiple doors or an opener system, as well as practicality.

Standard Sizes of Single Garage Doors

The 'typical' garage door measurements for a typical residential building are 7 x 7 feet or 7 x 6 feet 6 inches; both developers and independent builders frequently use these measurements. Unfortunately, average-sized modern cars have trouble passing through these-sized openings, especially when the doors are open.

However, keep in mind that larger garage doors won't fit properly if you're remodeling an existing garage without precise structural work being done.

Standard Size of Double Garage Doors

Double garage doors can fit two vehicles side-by-side due to their typical width of 14 or 16 feet (7 feet). When creating a garage from scratch, remember that you'll need enough room around the vehicles to park them safely and swing the doors open without running into nearby fixtures.

Can I Change the Size of My Garage Door?

Yeah, you can see this in the majority of scenarios. You'll need to think about structurally changing the garage opening, so contact a builder to review your options and the associated costs.

A completely custom door might be the easier solution. One option to further increase the drive-through clearance is to install the frame behind the brickwork.

Standard Garage Door Thickness:

The thickness of typical garage door panels is about 1/8 inch. Insulation might or might not be necessary, depending on how you use your garage. You might consider installing insulation if you spend much time in your garage. Proper insulation installed can maintain a 25-degree cooler temperature in the summer and a 12-degree warmer temperature in the winter in your garage. in addition to reducing energy costs.

Don't just take your own Measurements!

You must accurately measure every garage dimension, including the width, height, internal reveals, and internal headroom. We strongly advise you to rely on the expertise of a qualified, experienced fitter to complete this task correctly because they will also give you wise advice regarding your options. Different garage doors also call for various specifications, so all of these must be considered before filing an order.

Considering your Current Garage:

• Does your garage door's opening make it difficult to fit your car through?

• Are you planning to buy a large vehicle?

Whether you prefer an up-and-over garage door or a side-hinged garage door, Choose Garage Doors will aid in making your garage easier to access while offering you all the time and support you need when selecting the garage door that perfectly suits your needs.

How to Measure Your Garage Door?

We are happy to come out and measure your door if you are thinking about buying a new garage door so that you can make sure you are considering the appropriate options. However, suppose you prefer to do things independently. In that case, the following step-by-step instructions will help you measure your garage door and ensure it can fit in your garage with an opener and in both the open and closed positions.

  1. To the nearest inch, measure the "rough opening" of the door's width and height. This will resemble your door in size about equally.
  2. Measure the "side room"—the area to the left & right of the opening. 3.75 inches on each side are typically required for vertical track systems. Even more, the room is needed by some systems, measuring 5.5 inches.
  3. Calculate the "headroom," or the distance from the top of the opening to the ceiling. Most openers need an additional 3 inches of clearance and the 12 inches of headroom required by standard systems.
  4. Measure the distance between the garage door's opening and the garage's "backroom" wall. You will need additional backroom, possibly more depending on how the opener is installed, equal to the door height plus 18 inches.

Some Factors to Think About Before Purchasing New Garage Doors:

Are you constructing a new garage or purchasing a new garage door for an existing garage? Determine the precise size of door you require if you're looking to replace your garage door. This is where accurate garage measuring will be useful; we'll discuss it later.

  • You must be particularly aware of the available space in your garage for the "lifts." The tracks installed in your garage and allowing the door to open are called lifts. Which lift type you purchase will depend on your garage's goals and available space.
  • On the other hand, if you're building a new garage, you should consider what purpose you need it to fulfil. How many automobiles will you be parking in the garage? What size are they? What kind of architecture do you have in your house?
  • You are not required to have a certain garage door size just because your garage is a certain size. The doors in two garages of different sizes may be the same size. Different door sizes can exist in two garages of the same size.

These are all the points for choosing the right size for your garage and purchasing new garage doors.

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).
