How to Choose the Right Prefab Garage Size in VA, TN, KY, GA, and OH?

May 28, 2021      Shed Blog


When choosing to invest in a prefab garage to keep your vehicles and other valuables safe, the first thing you need to figure out is what prefab garage size will best meet your needs? Choosing a prefab garage size is one of the most important issues to consider when buying a new garage. While the cost of different types of garages can make it tempting to cut corners with the size of your garage, it’s important to keep in mind that the size of your garage in relation to the number of cars you want to store in your garage will have a major impact on the size. 

A Prefab Garage is a space where you can keep your car and tools safe by keeping them in an insulated place to keep them out of getting rusted under bad weather conditions. 

Also, a prefab garage could be used to store your car supplies, yard, and gardening tools, outdoor toys, or infrequently used items, if you need to store any items you rarely use or a temporary storage spot for items you ultimately plan to get rid of.

Learn the Average Prefab Garage Sizes

Before buying your prefab garage, you should decide how you want to use your garage, and then you can choose a prefab garage size that fits your needs. Many homeowners think it’s a good idea to go with one or two-car garages, but there is more to it.

There’s an average garage size for each garage style and a couple of secondary options. Knowing the space you’ll need is crucial before you decide. Don’t worry, we are here to help you choose the right prefab garage size for your needs.


What is the Average Prefab Garage Size?

The minimum size of single-car prefab garage size should be 12×16, but most cars will require a garage that is at least 12×20. The average garage size is 12 feet wide and 20 feet deep.

Some other one-car garage options are 12×20, 12×24, 12×28, and 12×30. These are some standard garage sizes that are offered almost everywhere. The bigger size garages will allow you to have more storage space while still having a car inside the prefab garage.


According to the “What is the Width and Length of the Average Car?” article, the average car is 6 to 6.5 feet wide. Now, if it’s a small car, it could be 5.5 feet. In any garage, you need 2 ft of clearance on either side of your vehicle in order to get in and out. So on average, you will need to have at least 10.5 feet width in your garage to store one car. And the length of the average car is about 13 feet. So you will need an average of 17 feet in length to be able to fit one car in your garage. 

At Timberline Barns, an average one-car prefab garage size 12×20 is starting at around $5,344 and can go up to $12,494. Prices for these prefab garages can vary depending on the different options that are available with the garage.

"I was very impressed..."


“I was very impressed with their customer service and the storage building/ garage (12×20) exceeded my expectations. They tailored it to exactly what I requested. My favorite part, though, was watching 1 man deliver, move the building of the trailer to the final spot, and set it up. All by himself. Me and my friends watched in amazement. And he was a great guy too. I highly recommend Timberline Barns.”

What is the Average 2-car Prefab Garage Size?

In short, the minimum 2-car prefab garage size should be 12×32, and to make extra space to get in and out of the car, it is recommended to go with 12 ft or larger. If you want to keep your vehicle looking nice and want extra space for other things, a bit wider and deeper will go a long way.

As we talked about before; the average car size is 6.5×13, and you will need 2 feet on each side of the wall to be able to fit your car comfortably in your garage. According to our calculations, you will need a 12×32 garage for a 2-car garage.

At Timberline Barns, a 12×32 average 2-car prefab garage prices start at around $8,344 and can go up to $12,494. Prices for these prefab garages can vary depending on the different options that are available with the garage.


What are standard prefab garage door sizes?

Average residential garage doors come in three sizes: 8×7 feet, 9×7 feet, and 10×7 feet.

At Timberline Barns, our residential standard garage door comes in 9×7 feet. This type of door will fit garages that house a single standard-sized car, SUV, truck, or van.

How much does a prefab garage cost?

At Timberline Barns, the average prefab garage prices can range from $5,344 up to $11,244 for the utility garage and $5,906 up to $12,494 for the lofted garage. That doesn’t include the foundation, delivery, or assembly. Completely pre-built garages cost anywhere from $5,000 to $20,000. These prefab garage prices can vary depending on the different options that are included with the prefab garage. For example, adding a lofted space can add to the price but will also give you additional overhead space for storage. You can add extra windows, doors, and vents to your prefab garage for more light and air circulation.
