How Wide Is A Two-Car Garage?

Garage Door Size Guide For Portland Area Home Owners

When planning a new garage or considering a renovation, understanding the dimensions that best suit your needs is essential. For many homeowners, a two-car garage offers the perfect balance between space and functionality. However, determining the ideal width for a two-car garage involves considering several factors, including vehicle size, storage needs, and personal preferences. This guide will explore the standard garage size for two-car garages, options for smaller 2 car garages, and how they compare to single-car garages.

Understanding Standard Garage Door Sizes

The standard garage size for a two-car residential garage in Portland typically ranges from 16 to 18 feet in width and 7 to 8 feet in height. This size is designed to comfortably fit two average-sized vehicles side by side with enough room for the doors to open and close without issues. The minimum recommended width for a two-car garage door is 16 feet, but opting for a few extra feet can significantly increase usability and comfort.

Smaller 2 Car Garage Dimensions

For homeowners with limited space or smaller vehicles, a smaller 2 car garage can be a practical solution. These garages can be as narrow as 15 feet wide, but this reduced width might limit the types of vehicles that can be parked inside and reduce extra storage or workspace. It’s crucial to consider the size of your vehicles and your needs for additional space when deciding on the dimensions of a smaller two-car garage.

Comparing to a Single Car Garage

A single car garage typically measures around 8 to 10 feet in width and 7 to 8 feet in height. While a single car garage may 

suffice for households with only one vehicle, a two-car garage offers more versatility, allowing space for an additional vehicle, storage, or even a workshop area. Upgrading from a single car garage to a two-car garage can enhance a property’s value and utility.

Factors to Consider

Vehicle Size: 

Measure your vehicles to ensure they will comfortably fit within the garage’s dimensions, allowing for ease of movement around them.

Storage Needs: 

Consider whether you need additional space for storage, tools, or hobbies, and plan the garage size accordingly.

Future Needs: 

Think about potential future needs, such as acquiring a larger vehicle or requiring more storage space.

Local Building Codes: 

Check local building codes and regulations, as they may dictate minimum size requirements or setbacks that affect your garage plans.


What is the most common size for a two-car garage?

The most common size for a two-car garage is approximately 16 to 18 feet in width and 7 to 8 feet in height.

Can you fit two SUVs in a smaller 2 car garage?

Fitting two SUVs in a smaller two-car garage may be tight, especially if the garage is on the lower end of the width spectrum. Carefully measuring your vehicles and considering the garage’s internal layout is essential.

Is it worth upgrading from a single to a standard garage size for two cars?

Upgrading to a two-car garage can offer increased storage, flexibility, and potentially add value to your property. If space and budget allow, it can be a worthwhile investment.

How much extra space should I allow for storage in a two-car garage?

Ideally, allow at least 2 to 4 feet of additional space on each side or the back of the garage for storage, depending on your specific needs.


Choosing the right width for a two-car garage door involves balancing your current needs with future possibilities. Whether you opt for the standard garage door size, a smaller configuration, or something in between, careful planning will ensure your garage serves you well for years to come. Remember to consider vehicle sizes, storage requirements, and local regulations to create a functional and efficient space that meets your needs.
