Other than keeping your car safe, garage doors also enhance the curb appeal of your home. Many factors play a part in determining how well the garage door will increase the aesthetic value of your home.

One of the most important among all of these factors is the garage door size. 

As far as garage door size is concerned, there is no standard one. But there are a few sizes of garage doors that are more common than others. For example, the most common size for single garage doors is 8’x7’ and 9’x7’. For double garage doors, the most common size is 16’x7’. You can also build custom garage doors according to your needs. 

Let’s take a look at the details of the sizes of garage doors. 

What sizes do garage doors come in?

Since garage doors play a big part in maintaining the curb appeal of your home, you have to be extra careful in choosing one for your home.

You must ensure the door is the right type, made of a suitable material, and of course, is of the right size. This way, not only will you be able to increase the aesthetic value of your home, but the functionality of the garage as well. 

Now, when we talk about standard garage door size, we don’t recommend a size that has been standardized by any authority. Rather, a standard garage door size is the one that most people use and hence has become standard by default.

This size depends on what type of door you are using. Let’s take a look.

1. Standard single garage door size

Single garages are used to keep only one car, and hence the doors in them tend to be much smaller than in other garages. The most common size of single-car garage doors is 8’x7’.

But nowadays, doors with 9 feet width and 7 feet height are also becoming very prominent. 

2. Standard double garage doors

If you have two cars in your home, then single garage doors won’t do the job. You will need to know about large garage door sizes so that you can move both cars at the same time without worrying about them brushing into each other. 

So, what is the standard size of a garage door for two cars?

The most common size for double garage doors is 16’x7’, which is twice as wide as a standard single garage door. 

3. Standard RV garage door

If you have an RV, then regular garage doors will not be enough, since the size, especially the height of the RV is much different than regular cars. There are quite a few standard garage door sizes for RVs.

You can get 10’x10’, 12’x12’, or 14’x14’ garage doors for your RV, depending on the size of the vehicle. 

4. Custom Garage door

It’s not always necessary that you will have to have cars that conform to the regular size. For example, you might have a wide truck, and hence, need more width in the garage.

In that case, you should measure the height and width of your vehicle, and buy a different size garage door accordingly.

What should you consider when choosing a garage door size?

When you are thinking about choosing the standard size of garage doors for your garage, there are a few things you need to consider. These are –

1. A double garage door vs a couple of single garage doors

As mentioned earlier

Garage Door TypeGarage Door Size
Single8’x7’ and 9’x7’
RV10’x10’. 12’x12’, and 14’x14’
CustomAccording to the need of the owner

If you have two cars, you will need a double garage door. But there is another way you can install doors to your large garage. Instead of using one double garage door, you can now install two single garage doors.

This will reduce the strain put on the parts of the garage doors by a double garage door due to its weight, and will also complement the style of most houses. 

On the other hand, two single garage doors will mean more parts to look after and maintain. This will bring your maintenance cost up, and take up a lot of your time.

So, you need to take your time, and budget into consideration and chose a garage door accordingly. 

2. The size of your vehicle

The key to choosing the best overhead door size for your garage is to measure the size of your car. The standard size of a single garage door being 8’x7’ doesn’t mean you have to follow this measurement every time. 

For example, you have a truck and need a garage for it. Then you should measure the width and height of your truck, which will determine the garage door height for trucks and its width.

3. Attached or detached garage

Another thing you have to consider while choosing the size of your garage door is whether your garage is attached to your home or a detached one. Usually, detached garage doors are used to house large vehicles.

So, if you have a detached garage, then you should consider getting a  larger garage door, according to the size of your vehicle.
