Are you designing your dream garage? If so, it’s important to know the ideal dimensions for your custom garage. The standard garage size for one car is 12 feet wide by 20 feet long (12×20), but this may not be suitable for you. Since the ideal garage size will vary person to person, there are several factors to take into consideration, including the number and type of vehicles you have, how much storage space you need, and more. In this article, we’ll show you several different sizes and dimensions to help you discover the perfect garage size for your not-so-standard cars.

Garage Dimensions at a Glance

The garage widths above generally provide enough space to open your car doors without scratching your paint or hitting the walls.

One-Car Garage Size

The average one-car garage size is 12 feet wide and 20 feet deep (12×20). This size is just large enough to fit one full-size car, minivan, or SUV. A single-car garage usually has a 9-foot-wide garage door. If you plan to store tools, lawnmowers, and other equipment in a one-car garage, you should opt for an 18-foot-wide garage (a “one-and-a-half-car” garage). You may also want to consider a garage that is deeper than 20 feet, which provides extra storage space. Additional sizes for a one-car garage include 12×25, 12×30, 18×25, and 18×30.

Width: 12 feet or more

12 feet or more Depth: 20 feet or more

20 feet or more Door Width: 8 to 10-foot wide

Two-Car Garage Size

A standard two-car garage size is a minimum 20 feet wide by 20 feet deep (20×20). Depending on the type of car you have, a standard 20×20 garage can be a bit cramped for two cars. You’ll want to ensure you can open car doors without hitting the other car or the wall. A 22-foot-wide garage is a more comfortable fit for two average-sized cars, and a 24-foot-wide garage allows two larger vehicles to park side-by-side. These vehicles can fit in a garage that is 20 feet deep, but a deeper garage will provide ample space. Other common sizes include 20×30, 24×25, and 24×30.

Width: 20 feet or more

20 feet or more Depth: 20 feet or more

20 feet or more Door Width: two 8 to 10-foot wide doors or one 16-foot wide door

Two-and-a-half-car garage

A standard two-and-a-half-car garage is generally 26 feet wide and at least 20 feet deep (26×20). This is a little larger than the usual two-car garage, but smaller than a three-car sized version. The extra space is ideal if you have additional vehicles such as a motorcycle, or for a storage or workshop area.

While the standard size for a three-car garage is 32 feet wide and 22 feet deep (32×22), a more ideal size is 36×24. The larger dimensions create additional room for trucks or storage.

Other popular dimensions for detached three-car garages include 32×24, 34×24, and 36×28.

To cut costs on this particular garage size, placing three garage doors on the side of your garage is less expensive than placing doors on the front (gable) end.

Width: 30 feet or more

30 feet or more Depth: 20 feet or more

20 feet or more Door Width: one 8 to 10-foot wide door and one 16-foot wide door

Four-Car Garage Size

The average four-car garage size is at least 40 feet wide and 20 feet deep (40×20), but a 24×45 garage is a more spacious size to park four cars comfortably. This allows you to park the less frequently used cars in the back of the garage and your daily drivers in the front. While a four-car garage isn’t as common as the others, many people who purchase this size use their garage as a workshop. Similar to the three-car size, if you want to park all your cars in parallel, it’s more affordable to place four garage doors on the side of your garage as opposed to the front (gable) end, because this design has a shorter, less-expensive roof.

Width: 40 feet or more

40 feet or more Depth: 20 feet or more

20 feet or more Door Width: four 8 to 10-foot wide doors, or two 16-foot wide doors

Garage Door Dimensions

As for garage doors, the standard height is seven to eight feet. The height, also referred to as the length, measures from the threshold to the door top. Door lengths are generally the same for all garage sizes unless you have an unusually tall vehicle like an RV.

Garage door widths, on the other hand, vary by garage size:

One-Car: 8–10 feet wide

8–10 feet wide Two-Car: Two 8–10 feet wide or one 12–16 feet wide Two 8–10 feet wide or one 12–16 feet wide Three-Car: One 8–10 feet wide and one 12–16 feet wide One 8–10 feet wide and one 12–16 feet wide Four-Car: Two 12–16 feet wide

Choosing a Garage Size: Factors to Consider

Now that you have an understanding of different garage sizes, the next step is to consider your intended use and needs. Below are a few factors to keep in mind while customizing your space.

How many vehicles do you own? Aside from cars, you may also need parking space for motorcycles, golf carts, scooters, ATVs, and bikes.

Size of Vehicles

It’s also ideal to know the average sizes of your vehicles, since some cars are small, and some are very big. A full-size car, minivan, or SUV is typically 14 to 17 feet long and at least 6 feet wide. In this case, a garage size at least 24 feet deep is ideal.

Attached vs. Detached Garage

To decide on the type of garage, consider the pros and cons of each. If you have an attached garage, it is really easy to get into your house after parking. However, attached garages must be custom-built on-site to connect to the house, and hiring a builder will be more expensive than buying a prefabricated (pre-built) detached garage. As for detached garages, a metal garage is the most affordable option. Since they’re prefabricated, they waste less material and help cut costs on labor. Additionally, detached garages offer more privacy.

Storage Space

If you need additional storage space for lawn and gardening tools, off-season decorations, and other recreational items, opt for a garage with more square footage than the average size. This will allow enough space between storage items and the parked cars inside. Many people use their garage for more than parking and storage. It can serve as a workshop for your DIY projects, a lounge area during the warmer seasons, and more. With this in mind, some people may prefer a two- or three-car garage size even if they only own one car.

Which Garage Size Is Best for You?

The best garage size will be the one with the right amount of space for your needs. What better way to achieve this than creating a custom metal garage? It’s affordable, sustainable, and quick to install.
