How many square feet is a two car garage?


When it comes to determining the size of a two-car garage, it’s essential to consider various factors such as the number and size of vehicles, storage needs, and available space. In this article, we will explore the average square footage of a two-car garage and provide insights into the considerations that can affect its size.

Average Square Footage of a Two-Car Garage

The average size of a two-car garage typically ranges from 400 to 600 square feet. However, it’s important to note that this is just a general guideline, and the actual size can vary depending on several factors.

Vehicle Size: The size of the vehicles you plan to park in the garage is a crucial consideration. If you own two compact cars, a smaller garage may suffice. On the other hand, if you have larger vehicles like SUVs or trucks, you may need a larger garage to accommodate them comfortably.

Storage Needs: Apart from parking vehicles, many homeowners use their garages for storage purposes. If you have additional items such as lawn equipment, tools, or bicycles that you plan to store in the garage, you will need to account for that extra space when determining the size.

Space Constraints: The available space on your property will also play a significant role in determining the size of your two-car garage. If you have limited space, you may need to consider a compact or narrow design to fit within the available area.

Factors Affecting Garage Size

While the average square footage provides a general idea, several factors can influence the size of a two-car garage. Let’s explore some of these factors in more detail:

Door Configuration: The type of door configuration you choose can impact the overall size of the garage. Traditional single-car garage doors are typically around 8 to 9 feet wide, while double-car garage doors can range from 14 to 18 feet wide. If you opt for wider doors, it will require more square footage to accommodate them.

Additional Space: If you plan to have additional space in your garage for a workbench, storage cabinets, or a small workshop area, you will need to factor in that extra square footage. This additional space can vary depending on your specific needs and preferences.

Building Codes and Regulations: Building codes and regulations set by local authorities may dictate the minimum size requirements for a two-car garage in your area. It’s crucial to check with your local building department to ensure compliance with these regulations.


In conclusion, the average square footage of a two-car garage typically falls between 400 and 600 square feet. However, it’s important to consider various factors such as vehicle size, storage needs, and available space when determining the size of your garage. Additionally, factors like door configuration, additional space requirements, and local building codes can also influence the overall size. It’s always recommended to consult with professionals or local authorities to ensure your garage meets all necessary requirements.
