How many sq ft is a 2 car garage?


A two-car garage is a popular addition to many homes, providing a convenient space for parking vehicles and storing other items. But how many square feet does a typical two-car garage occupy? In this article, we will explore the average size of a two-car garage and discuss factors that can influence its dimensions.

Standard Size of a Two-Car Garage

The standard size of a two-car garage can vary, but a common dimension is around 20 feet wide by 20 feet deep, resulting in a total area of 400 square feet. This size allows for two standard-sized vehicles to be parked comfortably side by side, with enough space for opening car doors and maneuvering between the vehicles.

However, it’s important to note that this is just a general guideline, and the actual size of a two-car garage can differ based on various factors.

Factors Influencing Size

Several factors can influence the size of a two-car garage, including:

1. Vehicle Size: If you own larger vehicles such as trucks or SUVs, you may need a wider or deeper garage to accommodate them comfortably. In such cases, the standard 20 feet by 20 feet size may not be sufficient, and you might consider increasing the dimensions accordingly.

2. Storage Needs: Apart from parking vehicles, many people use their garages for additional storage. If you plan to store items like tools, lawn equipment, or bicycles, you may need to allocate extra space for storage cabinets, shelves, or workbenches. This can influence the overall size of your two-car garage.

3. Additional Features: Some homeowners opt to include additional features in their garages, such as a workshop area, laundry facilities, or a small office space. These additions can increase the overall square footage required for the garage.

4. Local Building Codes: Building codes and regulations can also impact the size of a two-car garage. It’s important to check with your local authorities to ensure compliance with any specific requirements or restrictions.

Considering these factors, it’s clear that the size of a two-car garage can vary significantly from one homeowner to another.

Other Garage Sizes

While a 20 feet by 20 feet garage is a common size for a two-car garage, it’s worth noting that there are alternative dimensions available. Some homeowners may prefer a wider garage, such as 24 feet by 24 feet, to provide more space for maneuvering or additional storage. Others may opt for a deeper garage, such as 20 feet by 30 feet, to accommodate larger vehicles or create extra workspace.

It’s essential to assess your specific needs and consider any future requirements when determining the size of your two-car garage.


The size of a two-car garage can vary depending on factors such as vehicle size, storage needs, additional features, and local building codes. While a standard size is around 20 feet by 20 feet, homeowners may choose different dimensions to suit their specific requirements. It’s crucial to carefully consider these factors and plan accordingly to ensure that your two-car garage meets your needs effectively.
