How many square feet is a one car garage?


A one-car garage is a common feature in many residential properties. It provides homeowners with a designated space to park their vehicles and offers additional storage or workspace. If you’re considering building or purchasing a one-car garage, you may be wondering how many square feet it typically occupies. In this article, we will explore the average size of a one-car garage and factors that can influence its dimensions.

Standard Size of a One-Car Garage

The standard size of a one-car garage can vary depending on several factors, including the region, local building codes, and personal preferences. However, the most common dimensions for a one-car garage are approximately 12 feet wide by 22 feet deep, resulting in a total area of 264 square feet. This size allows enough space for a single vehicle and some additional storage or workspace.

It’s important to note that these dimensions are considered standard, but they are not set in stone. Some homeowners may choose to build larger or smaller garages based on their specific needs and available space.

Factors Influencing Garage Size

While the standard size mentioned above is a good starting point, several factors can influence the size of a one-car garage. These factors include:

Vehicle Size: The size of the vehicle you plan to park in the garage will play a significant role in determining the necessary dimensions. If you own a compact car, the standard size may be sufficient. However, if you have a larger vehicle, such as an SUV or truck, you may need to consider a wider or longer garage to accommodate it comfortably.

Additional Storage or Workspace: Many homeowners use their garages not only for parking vehicles but also for storing tools, equipment, or other belongings. If you require additional storage space or plan to set up a workshop, you may need to increase the size of the garage accordingly.

Local Building Codes: Local building codes and regulations can dictate the minimum size requirements for a one-car garage in your area. It’s essential to consult with your local authorities or a professional builder to ensure compliance with these regulations.

Alternative Sizes

While the standard size of a one-car garage is commonly used, it’s worth noting that alternative sizes are also available. Some homeowners may prefer a narrower garage to maximize space in other areas, while others may opt for a wider garage to accommodate larger vehicles or provide additional storage.

If you have limited space or specific requirements, you can consider alternative dimensions such as 10 feet by 20 feet (200 square feet) or 14 feet by 20 feet (280 square feet). These variations can be customized to suit your needs while still providing adequate space for a single vehicle.


In conclusion, the average size of a one-car garage is approximately 12 feet wide by 22 feet deep, resulting in a total area of 264 square feet. However, various factors, including vehicle size, storage needs, and local building codes, can influence the dimensions of a one-car garage. It’s important to consider these factors and customize the garage size to meet your specific requirements.
