4-Car Garage Dimensions for Optimum Space Utilization

If you plan to erect a new 4-car garage on your property, you probably have many questions about what dimensions you need. Garages are for more than just parking your car, as they provide extra storage outside of your home.

Consider this article as your complete guide to 4-car garage dimensions, so you can build the ideal 4-car garage for your needs.

What Is the Standard Size of a 4-car Garage?

The standard size of a 4-car garage has a depth of 20 to 24 feet, a width of 34 to 44 feet. Each door is about 16 feet wide, and the height of a 4-car garage is the same as any other size garage. The standard height of a garage is between seven and eight feet, with plenty of room for most passenger vehicles.

Standard 4-car Garage Size in Square Feet

A standard 4-car garage is unusually between 800 square feet and 1060 square feet. This square footage is far larger than the size of a one-car garage which is usually between 150 square feet and 400 square feet.

An 800 square foot 4-car garage can likely not fit much else besides the vehicles, while a 1060 square foot garage will have extra space for storage and other items you want to keep in the garage.

Standard 4-car Garage Dimensions in Meters

The length, also called the depth, of a 4-car garage is between 6 and 7.7 meters deep. The width of a 4-car garage, which is how far across the doors stretch, is between 10 and 14 meters. And lastly, the height of a standard 4-car garage is around 2.5 meters tall, but never less than 2.2 meters tall.

Standard 4-car Garage Size in Yards

The depth of a 4-car garage is between 6.5 yards and 8 yards. The width of the 4-car garage will be between 11 and 14.5 yards. Finally, the height of a 4-car garage and all standard garages is about 2.5 yards, or somewhere between 2.3 yards and 2.6 yards.

Minimum Dimensions For a 4-car Garage

The minimum dimensions for a garage to fit four-passenger vehicles are a depth of 20 feet, a height of 7 feet, and a width of 34 feet. A garage of this size will snugly fit four vehicles but will not have extra room for storage and other bulky items people like to keep in their garage.

Minimum Dimensions in Square Feet

The smallest square footage of a 4-car garage is 800 square feet. For perspective, 800 square feet is about the size of four parking spaces in a parking lot. You may be thinking this means you have wiggle room around your cars for extra equipment, but parking inside a garage does not allow as much wiggle room as parking in an open parking lot.

Minimum Dimensions in Meters

The smallest width you can have for a 4-car garage is 10 meters. This size allows enough room for the two garage doors to fit two vehicles each. The height must be around 2 meters and no lower than that. And the smallest depth you can have in a 4-car garage is no less than 6 meters deep.

Minimum Dimensions in Yards

The minimum dimensions for a 4-car garage in the yard are as follows: a height of 2 yards, a depth of 6.7 yards, any less and longer vehicles like pickup trucks may not fit safely, and a width of about 11 yards across.

Oversized 4-car Garage Dimensions

To qualify as an oversized 4-car garage, the dimensions would need to be at least 44 feet wide, 24 feet deep, and 8 feet tall.

Minimum Dimensions in Square Feet

The smallest size garage that can be considered an oversized 4-car garage will be around 1,050 square feet. For perspective, this is almost the size of 6 parking spaces. To be exact, it’s about the size of 5.8 parking spaces, giving you an extra 250 square feet to fit equipment and other items around your vehicles.

Minimum Dimensions in Meters

The dimensions for an oversized -car garage in meters are as follows: width of 13.4 meters, a depth of at least 7.5 meters, and a height of 2.5 meters.

Minimum Dimensions in Yards

In yards, the minimum dimensions for an oversized 4-car garage are about 14.5 yards, with a depth of exactly 8 yards, and a height of at least 2.5 yards, but these garages are usually a bit taller to allow for ceiling storage.

4-car Tandem Garage Dimensions

First of all, what is a tandem garage? A tandem garage means the cars do not park beside one another, but two cars block in other two cars. These garages have pros and cons, as not all vehicles can be used freely, but they often work better for property layouts.

The standard dimensions for a 4-car tandem garage are about 20 feet wide, 40 feet long, and 7 feet tall. In tandem garages, the length and the depth are the same things.

Tandem Garage Dimensions in Square Feet

When discussing the square footage of a tandem garage, it will be about the same as a standard 4-car garage. So the average size will be around 900 square feet or the size of 5 parking spaces.

Tandem Garage Dimensions in Meters

The average 4-car tandem garage dimensions will be 6 meters wide, about 12 meters deep, enough to fit two cars, one behind the other. And the height of the garage should be just over 2 meters to allow large passenger vehicles to fit.

Tandem Garage Dimensions in Yards

In yards, the average dimensions of a tandem 4-car garage will be 6.5 yards wide, 13 yards deep, and 2.5 yards in height.

Standard Garage Height

The standard height for all garages no matter how many cars or if it is tandem or not is between 7 and 8 feet. The average height of a passenger vehicle is about 6.5 feet, so most cars can fit. Some garages are as tall as 12 feet, but even a large pickup truck should fit in an 8-foot tall garage.

Standard Height in Feet

Most garages will be 7 feet tall, as most people don’t have a reason to have a super tall ceiling in their garage. As mentioned, passenger vehicles are usually shorter than 6.5 feet.

Standard Height in Meters

The standard height of a garage in meters is just over 2 meters. To be exact, the average height of a garage is 2.1 meters.

How Deep is a 4-car Garage on Average?

On average, the depth of a 4-car garage is about 22 feet. Most people choose this depth because it isn’t too large of a garage but allows for some storage space.

Standard 4 Car Garage Door Dimensions

A standard 4-car garage will have two garage doors. Each door will be about 8 feet wide and 7 feet tall for a total area of 56 square feet.

Standard Garage Door Height

The garage door height usually is slightly smaller than the height of the garage itself. So a 7-foot tall garage will have a door that’s about 6.8 feet tall. But a garage that is about 8 feet tall will have a garage door closer to 7.5 or 7.8 feet tall.

Standard Garage Door Width

The standard width of a garage door is about 8 feet wide. So two doors across will be 16 feet put together plus a few feet for the space on either side of each door.

Things to Consider When Planning a 4-car Garage

Below are some factors to keep in mind when planning your new 4-car garage.


If you have lots of gardening or maintenance equipment that you store in your garage, plus four vehicles, you’re going to want some extra wiggle room around the cars. Many people store items like snowboards, bicycles, and sports equipment in their garages.

If you have many items like the ones mentioned above, you should consider opting for an oversized 4-car garage, so you have plenty of extra room to fit your items.

Other Machinery

Do you have a lawnmower or a snowplow you need to store? Machinery and large equipment should factor into your final decision on the dimensions of your garage.

Vehicle Usage

If you only use two of your vehicles, or one, most of the time, a tandem garage may be a good choice for you. Tandem garages fit better on some properties and only require one garage door, saving money during construction.

Property Size

Of course, you can only build a garage as large as your property will allow. Make sure you know how much available space you have on your property.


It’s always wise to set a budget when starting a large project like building a garage. Consider how much space you actually need and set your budget accordingly.
