Square Footage of 2 Car Garage

Wondering what’s the square footage for a 2-car garage? Well, it’s a bit big, but not so big - about 20ft in length and 18ft in width.

It’s no big surprise seeing a family that owns more than one car, or maybe you’ve got one and wish to buy another to make it two. Owning two cars is not a problem - it’s not even a big deal. The real issue is where to park them.

Parking your cars outside will fade the paint too soon and expose the car to other potential dangers. This article explains the measurement for a 2-car garage. When you know the square footage for a 2-car garage, you can map out some space in your home to build parking space for your cars.

Square Footage for 2-Car Garage

While you may decide to make yours bigger, most 2-car garages have estimated length and width measurements: 20ft for the length and 18 ft. for the width. Of course, if you have longer or bigger cars like trucks, vans, and wagons, you may want to increase these measurements to have more space in the depth (length) and width.

Usually, the doors are about 16 feet wide, more than 80% of the total width. You could have two separate doors for the garage.

The square foot measurement is obtained by multiplying the width and length of the garage. By going with our measurements above, the footage for a typical 2-car garage is around 360 sq. ft. Again, this is basically the average measurement. Yours could be bigger.

Knowing the square footage for your garage is a good idea. It helps you do proper planning. Well, some houses have a smaller space for a garage, and some have a bigger space.

The garage may be a bit smaller than the estimated measurement above for smaller houses - but certainly, it’d accommodate two cars.

Furthermore, there are other common sizes for 2-car garages. These are pretty much bigger than 360 sq. ft. The sizes are 20 ft. by 20 ft. (400 sq. ft.), 24 ft. by 24 ft. (576 sq. ft.), and 24 ft. by 30 ft. (720 sq. ft.). Naturally, the size of the garages is dependent on the house size. Bigger houses tend to have wider garages than smaller ones. Also, if you’re building a garage by yourself, you’d want to give ample space (just as you’d want it) for your two cars.

Factors To Consider When Building a Garage

If your house has a garage space, you just have to stick with whatever size it is. However, if you’re planning to build your own garage space from scratch, there are factors you need to consider to come up with a perfect “size.”

These factors are relevant, especially if you’re the type that DIYs most of your car repairs or troubleshooting.

How Big Is Your Compound

The free space you’ve got left in the compound plays a huge role in determining the size of your garage. If you’ve got much bigger space, you’d want a bigger garage.

Car Sizes

What kind of cars do you have? Are they typically longer, bigger, or wider than regular cars? If yes, you’d want to consider these things when deciding the garage size. Longer vehicles will mean your garage will be longer than the estimates above.


Would you love to have a workshop in the garage? Where you could keep some regular items you use in troubleshooting the car, running oil changes, and other mechanical DIY services. If you’d have a workshop or want more space to keep some items, then you’d want a wider/longer garage.

Miscellaneous Purposes

Some people use their garage as more than just a car park - they set up other stuff in there for specific purposes. Perhaps you’d love to use the garage space for other activities. You should consider this factor when building one for yourself.

What More?

The square footage measurement for a 2-car garage may vary greatly depending on many factors. However, the commonly recognized square footage for 2-car garages is 20 ft. by 18 ft. (360 sq. ft.), 20 ft. by 20 ft. (400 sq. ft.), 24 ft. by 24 ft. (576 sq. ft.), and 24 ft. by 30 ft. (720 sq.ft.).

Any size aside, these ones are still okay - provided it gives you the perfect space for your two cars.
