Standard Carport & Garage Sizes and Dimensions

The standard 2-car garage or carport size is usually 20’x20′ or 22’x22′. However, these dimensions will only fit two small-sized cars: The average garage size doesn’t allow much extra room for movement, storage, or other purposes. That is why we usually recommend a 24’x25′ carport or garage for 2 cars.

What Size Carport Do I Need?

When you’re building a new garage or carport for your home, the most important question to ask yourself is, “What size garage do I need?” The answer to that question depends on the amount and size of the vehicles you need to be covered, as well as what else you plan to use the space for. Whether you’re wondering about the average 2-car garage dimensions or are searching for a carport big enough for the whole family’s vehicles, or interested in an RV carport for, we can help you find and customize the right structure for your needs.

Most people looking to buy a carport or garage are looking for somewhere to put their vehicles, so the first thing to consider is how many cars you need to keep covered.

Number of Vehicles   Standard Carport/Garage Width
112-18 feet
220-24 feet
330-38 feet
440-48 feet
550-60 feet

You’ll also want to think about how big your vehicles are. Do you need a 12-foot-wide single-car garage just big enough to fit your coupe, or would it be better to look at two-car garages spacious enough for a pair of sedans? If you have a couple of large SUVs, you’ll want to err on the larger side for your new storage structure; maybe 3-car garage dimensions would be a better fit, giving you plenty of space to walk around both vehicles. From the smallest one-car garage size to carports large enough for a whole fleet, Alan’s Factory Outlet has an option for every need at a great price!

What Size Carport Do I Need for 2 Cars Plus Extra Storage Space?

You’ll want to size up to at least a 2 1/2-car garage if you plan to use your new structure for storing other things in addition to your vehicles; if you buy a standard 2-car garage, the square footage won’t be generous enough for extra storage.

Frequently Asked Questions

What Is the Minimum Width for a Single-Car Garage?

The minimum width of a garage is typically 10 feet, and garage door sizes to fit are usually scaled down to the minimum width of 8 feet. But you’ll need to think about the size of your vehicle and the length of its doors before purchasing this size: It may be true that on average, the minimum single-car garage size is 10 feet wide by 18 feet long, but those numbers mean nothing if you can’t get the doors of your SUV open once you’ve parked inside!

What Is the Standard Size of a Single Garage?

The average one-car garage size is 12 feet wide by 20 feet deep, but other standard size options are also common, such as 12’x25′ and 18’x20′.

How Big Is a Single-Car Garage in Meters?

A standard single-car garage is 3.6 meters by 3.6 meters on average and usually has a door size that is 2.6 meters wide. This size allows your car to fit comfortably and leaves you some space to move around the vehicle.

How Long Is a Standard Garage?

The standard garage is 18 to 20 feet long.

How Deep Should a Garage Be for a Full-Size Pickup?

Since pickup trucks are usually much larger than the average car length, you’ll want to choose a garage that’s at least 24 feet deep. This will give you plenty of space to walk around the front and back of the truck.

What Size Garage Door Do I Need for 2 Cars?

Standard garage door sizes are around 9 feet wide for a single car, and you’ll find that the standard 2-car garage door dimensions are nearly twice that, averaging 16 feet wide.

What Size Is a 4-Car Garage?

The typical 4-car garage dimensions include a width of at least 36 feet, a depth of 20 to 24 feet, and a door width of about 16 feet per door (in a two-door configuration).

What Is the Minimum Width of a Carport?

The minimum functional width of a one-vehicle carport is 12 feet. This size will fit a small car to a midsize sedan, but if you have anything larger than that, you will need a larger carport.

What Sizes Do Carports Come In?

You can get carports in a wide variety of different lengths, widths, and heights, ranging from as small as 12 feet by 21 feet to as large as 18 feet by 42 feet. We also offer custom sizes.

How Much Space Does a Car Need in a Garage?

The ideal garage will be at least 4 feet wider and deeper than the size of your vehicle to ensure that you can walk all the way around it and get in and out comfortably, but this will vary depending on the length of your vehicle’s doors. Since the average width of a car is around 6 feet, that means that you’ll need at least a 10-foot-wide garage.

What Is the Minimum Ceiling Height for a Garage?

A garage ceiling needs to be no less than 9 feet high. This height can accommodate both regular doors and garage doors, but going up to 10 feet high is recommended, as it’s more comfortable and allows for taller garage doors.

What Is Considered a Large Garage?

A typical 3-car garage size or larger is usually considered to be a large garage. These garages are usually 32 feet wide by 22 feet deep, but they can go much larger depending on your needs.

How Much Room Do You Need to Open a Car Door?

You’ll usually need at least 2 feet to comfortably open a car door, but if your vehicle has very long doors, more space will be needed.

How Do I Calculate the Square Footage of My Garage?

To find out the square footage of a garage or another space, multiply the length of the interior by the width. For an average two-car garage size, measuring 20 feet by 20 feet, you would multiply 20 by 20 to get 400 square feet.

How Are Carports Measured?

The width of a carport is measured from outside to outside of the base rails, the height is measured by the length of the legs plus 1 foot, and the length of a carport is measured from front leg to back leg.

Let’s say you are looking to buy a 12-foot-wide boxed-eave or vertical-roof carport with 12′ legs to store your RV. With the 12′ legs, the clearance in the middle of the carport is 1’7″ taller than the leg height, for a total height of 13’7″. But that is just in the middle, so leave some extra room so you’ll have plenty of clearance.
