Optimal Width for a Two-Car Garage: A Comprehensive Guide

Ever found yourself wondering about the dimensions of a two-car garage? It’s a question that often pops up, especially when planning a new home or considering a renovation. In this article, we’ll delve into the specifics of garage sizes and what you need to consider for a two-car setup.

Key Takeaways

  • A standard two-car garage typically measures between 20 to 24 feet wide. This width provides enough room for two average-sized vehicles and facilitates comfortable movement around the garage.
  • The garage’s interior layout, including plans for workbenches or additional storage, can affect the need for a wider space. A well-planned layout maximizes utility and reduces clutter.
  • Factors such as vehicle size and type, and storage and functionality needs can influence the ideal width of a two-car garage. Owners of larger vehicles or those requiring additional space for storage or functions may benefit from a wider garage.
  • Adequate space is needed for opening vehicle doors, meaning an extra width of 4 to 6 feet is typically ideal. This avoids hitting walls, other vehicles, or objects within the garage.
  • Extra features inside the garage, like shelves, cabinets, workspace or fitness area, require careful planning and additional space allocation. For example, you might need an extra 7 feet for shelving units and a workbench.
  • The dimensions of a two-car garage depend on individual needs and preferences. Taking into account your vehicle’s space requirements and planning for future needs will ensure a functional, spacious garage.

Understanding the Dimensions of a 2 Car Garage

Standard Width for Convenience

Most two-car garages are typically between 20 to 24 feet wide. It offers enough space for two average-sized vehicles, providing that slight buffer zone if doors of both vehicles were opened simultaneously. Remember, this standard width ensures comfortable movement around the garage, too, without the worry of scratches or dents.

Importance of Interior Layout

Equally crucial is the garage’s interior layout. While exterior dimensions are vital, the effective utilization of available space inside shapes your garage’s functionality. For instance, if you’re planning a workbench or additional storage, you may require more width. Factoring in these features while deciding on a two-car garage’s width creates an accommodating and efficient space for all your storage and vehicle parking needs. Remember, a well-planned layout reduces clutter and maximizes your garage’s utility.

Factors Influencing the Width of a 2 Car Garage

Given the standard size of a two-car garage, variations factor in based on individual characteristics. Let’s delve into the specifics that influence these dimensions.

Vehicle Size and Type

First off, vehicle size and type significantly impact garage width. Broadly speaking, a small sedan occupies less space compared to an SUV or a pickup truck. For instance, an average mid-size sedan measures roughly 6 to 6.5 feet in width. In contrast, a larger vehicle, such as an SUV or a pickup truck, takes up about 6.5 to 7 feet. So, if you own larger vehicles, you’ll likely find the need for a wider garage space. Remember, garage width isn’t just about fitting in your cars; it’s about comfortably moving around them, opening doors without hitting walls or the other vehicle, and ensuring your vehicles stay protected.

Storage and Functionality Needs

Next, consider storage and functionality needs. If your garage doubles up as a workshop, storage area, or recreational space, you’ll need additional square footage. Whether it’s shelving units, workbenches, gym equipment, or even bicycles and lawn equipment, each adds to the breadth required. For instance, shelving units might require an additional 2 to 3 feet, while a workbench might need anywhere from 3 to 5 feet. As a rule, any additional functionality beyond parking vehicles necessitates extra width. By taking into account your specific storage and functionality needs, you can design a garage that’s not just wide enough but also efficient and well-organized.

Design Considerations for Optimal Utilization

Incorporating smart design choices enables us to optimize two-car garage spaces, regardless of their width. By carefully considering factors such as room for opening doors and the inclusion of additional features, we can maximize utility and efficiency.

Space for Opening Doors

An important consideration often overlooked is the space needed for opening vehicle doors. Without adequate space, there’s a risk of hitting walls, other vehicles, or various objects within the garage. For most cars, a clearance of 2 to 3 feet is sufficient for comfortably opening doors. Thus, with two cars parked side by side, an extra width of 4 to 6 feet seems ideal. This space also permits easy movement between vehicles.

Additional Features Inside the Garage

Many homeowners choose to incorporate additional features inside their two-car garage. This can range from installing shelves and cabinets for extra storage, to setting up a small workspace or fitness area. Here, optimal design plays a key role. For instance, with an average width of 2 feet required for shelving units and 5 feet for a standard workbench, you need to reserve about 7 feet for these features. These figures vary, of course, depending on personal requirements and space available.

Remember that these additions, while enhancing the functionality of your garage, also necessitate a larger footprint. Careful planning, thus, is critical to ensure that these features integrate seamlessly with vehicle parking and do not impede functionality.

Choosing the Right Dimensions for Your Needs

Determining the perfect dimensions for your double garage depends largely on individual needs and preferences. While bearing in mind standard two-car garage widths, the spaces you tailor within those set parameters make the difference.

Assessing Your Vehicle Space Requirements

Knowing your current vehicle sizes provides a baseline when deciding on garage dimensions. Do an inventory of the cars you own. Make a note of their widths including mirrors, and consider the space they need for movement such as opening doors. If your vehicles are spacious SUVs, for instance, then you’ll require bigger garage dimensions compared to compact cars.

Use my example: I own a mid-sized sedan and an SUV. Including the space for opening doors and maneuvering around, I found a 24-feet wide garage optimal.

Planning for Future Needs

It doesn’t hurt to future-proof your space. You may stick to sedans now, but who knows? You might be the proud owner of a broad pickup truck in the future. Allocating additional space for such eventualities ensures your garage stays relevant with your lifestyle changes.

Also, consider the propensity for storage needs to grow over time. Allow for extra width to accommodate shelves, cabinets, and workbenches. Remember, you’ll also need walking space without infringing on parking areas.

For instance, in my garage, I factored in a 5-feet wide space for storage and work areas, accounting for future additions of tools and rarely used items.

Determining two-car garage width involves understanding current spatial requirements while factoring in potential future needs. Careful planning guarantees your garage remains a functional, rewarding addition to your home over time.


Having the right dimensions for your two-car garage is more than just about parking. It’s about future-proofing your space. You’ve got to consider current car sizes and potential future vehicles. You might decide to buy an SUV or a truck down the line, and you’ll want to ensure your garage can accommodate these larger vehicles. Plus, it’s not just about the cars. You might need extra space for storage or a work area. So, when you’re planning your garage, don’t just think about the here and now. Think about what you might need in the future too. That’s the key to a functional, optimized garage space.
