One-Car Garage Sizes: The Complete Guide

One car garages come in many shapes and sizes. Some come with an A-roof, others with a Gambrel roof and all offer advantages and disadvantages. But one of the basic questions when considering a one car garage might be:

How large should a one-car garage be?

The minimum size of a one-car garage should be 10×18 but most cars will require a garage that is at least 12×20. If you are driving a Smart Car, then a 10×12 might work! But otherwise, even the most compact cars will require a 20-foot long garage to fit inside comfortably. You don’t want to be crashing into the wall while backing your vehicle into the garage!

The garage photo above features an 18×26 One Car Garage with an extra wide garage door and plenty of overhead space. 

What if I want more Space inside my One-Car Garage?

That is a great question. In the example to the left, you can see a larger vehicle such as a full-sized pickup inside a 25-foot long garage. It is easy to see there is little room left for a workbench and other needs.

If you want extra space besides your space for a vehicle then you’ll need to do some extra planning. Make sure you measure your car or truck first, then decide on the best size for your one car garage and the extra space you need. 

A-One Car Garage with Office Space

Now let’s get creative. How about a 16×20 One Car Garage with an extra space for a home office, art studio or man cave?  You could store the vehicle in the garage and then have a space to tinker or gather with friends in the other section. Or use the extra space as a workshop and storage space. Add a workbench and some shelves and you’ll have the garage/workshop of your dreams!

Let’s look at more possibilities for your very own prefab one car garage.

Choosing the Right Sized One Car Garage

When you are deciding on the best size for a one car garage, ask the question

What am I going to store besides a car?

If the only thing you need room for in your single car garage is… a car… you may be able to get by with a smaller option. Here are a few examples of one-car garages of different sizes. We start by going from small to large, with less space to more space.

A-One Car Garage for your Smart Car

Smart cars are about all you’ll be able to fit into this Mini One Car Garage. At 10×12, this Standard Workshop Garage will give you space for a smart car and maybe a shelf on the back wall for storing some extra stuff. This tiny one-car garage would also be a good fit for a small tractor or lawnmower as well as other garden tools. 

This One Car Garage is so small that we don’t even have a price for it on our website. If you want prices, request a customized quote via our form. 

The Dutch Barn One Car Garage

Next, we take a giant step forward to the Dutch Barn Garages. Not every garage offers the same interior storage space even when the footprint is equal. Here, you see a Dutch Barn Garage that offers more interior height than most of our single story one car garages. The high barn roof design means you’ll have more space for storage in the loft area and less clutter on the floor. 

Get this garage if you want plenty of space for a loft.

Get Even More Space in a Two Story Garage

Maybe you don’t want to take up a lot of space from your property but you need lots of storage space. The Legacy Two Story MaxiBarn takes us to a whole new level (literally) and gives you almost double the storage space with a full second floor and a stairway with easy access.

This building can be quickly assembled on your site and you can be enjoying extra space in a matter of hours after our team arrives. 

Use a Double Wide for Your One Car Garage

Using a Modular Garage like the 20×24 above for a one car garage has definite advantages for the homeowner looking for storage space.

Now you can pull your vehicle inside while also having room for the mower, your bikes, utility vehicles, and much more. These modular garages are also ideal to be used as two-car garages by installing two garage doors.
