When planning a new garage, one of the most common questions is how big is a two car garage. The answer is more nuanced than you might think, as you need to consider not just the size of your vehicles but also the clearance needed for opening doors comfortably, moving around, and storing other items.
A standard two-car garage is typically 20 feet wide by 20 feet deep. This gives you 400 square feet of space. However, this minimum size often leads to a cramped experience. Modern vehicles, especially trucks and SUVs, are wider and longer than ever before.
Building or buying a home with a garage that’s too small is a frustrating and costly mistake. This guide will walk you through the exact dimensions you need, factors to consider, and how to plan for a garage that truly works for your lifestyle.
How Big Is A Two Car Garage
The traditional 20×20 foot two-car garage is becoming a relic. While it’s the baseline you’ll often see in building plans, it’s rarely sufficient for modern life. Let’s break down what these dimensions actually mean for your cars.
In a 20×20 space, two mid-sized sedans will fit, but just barely. You’ll have to park perfectly centered to avoid scraping the walls. Once inside, opening the car doors fully becomes a challenge. You’ll likely have to shuffle out sideways.
For a much more functional and comfortable garage, the recommended minimum size is 24 feet wide by 24 feet deep. This 576 square foot footprint provides crucial extra space. It allows for full door opening, space for a workbench or storage shelves, and easier movement between the vehicles.
Standard Dimensions And Minimum Clearances
Understanding standard clearances is key to good garage design. These are the buffers of space that make a garage usable, not just a parking slot.
First, consider vehicle width. The average car is about 6 to 6.5 feet wide. A full-size pickup or SUV can be over 6.5 feet wide without mirrors. Now, add the essential clearance.
- Side-to-Side Clearance: Aim for at least 2 feet of space between the two vehicles. This allows doors to open without dinging the adjacent car. Also, plan for a minimum of 3 feet between each vehicle and the side walls for safe entry and exit.
- Front-to-Back Clearance: A depth of 20 feet leaves little room in front or behind the cars. With a 24-foot depth, you gain space for storage cabinets, bicycles, or a deep freezer at the front wall without blocking the vehicles.
- Door Clearance: Remember the garage door itself. You need space for it to open and close without obstruction. An overhead door needs the full clear width of the opening.
Accounting For Modern Vehicle Sizes
Cars have grown. According to industry data, the average new vehicle has gotten significantly wider over the past two decades. A standard 20-foot width assumes cars that are no longer the norm.
Parking two modern SUVs, like a Chevrolet Tahoe and a Honda Pilot, in a 20×20 garage is nearly impossible without constant door contact. Their combined widths, plus the necessary clearance, easily exceeds 20 feet.
If your household includes larger vehicles, you must adjust your plans. For two full-size trucks or SUVs, a garage width of 26 to 28 feet is a wise investment. The extra cost during construction is minor compared to the daily inconvenience of a too-tight fit.
Popular Vehicle Dimensions for Planning
- Midsize Sedan (Toyota Camry): Approx. 6 ft wide, 16 ft long.
- Full-Size SUV (Ford Expedition): Approx. 6.5 ft wide, 18 ft long.
- Crew Cab Pickup (Ford F-150): Approx. 6.5 ft wide, 19 ft long.
- Compact SUV (Honda CR-V): Approx. 6 ft wide, 15.5 ft long.
The Impact Of Garage Door Size And Placement
The garage door is the gateway, and its size and style directly impact how you use the space. A common mistake is installing a single 16-foot wide door for a two-car garage.
A single wide door means you have a large, obstructive door track running down the center of your ceiling. This can limit storage options and light placement. The recommended setup is two separate 8-foot or 9-foot wide doors. This provides a structural support column in the middle, which can actually be useful for organization.
Door height is another critical factor. Standard door height is 7 feet, but many modern SUVs and trucks are taller. An 8-foot tall door prevents scrapes and gives you flexibility for roof racks or future vehicle changes.
Planning For Functionality Beyond Parking
For most people, a garage is more than just a carport. It’s a workshop, a storage facility, a gym, or a hobby space. Failing to plan for these functions is a missed opportunity.
When you ask “how big should my two-car garage be,” you must also ask, “what else will I do in it?” The depth of the garage is especially important for adding functionality without sacrificing parking.
Incorporating Storage And Workspace
Effective storage is the key to a clean, usable garage. Clutter on the floor quickly eats into your parking space. Planning for built-in or modular storage from the start maximizes every square foot.
Consider these storage solutions and the space they require:
- Wall-Mounted Cabinets and Shelving: These keep items off the floor. Plan for at least 2 feet of depth along the side or back walls for this purpose.
- Overhead Storage Racks: Perfect for seasonal items. They utilize the vertical space above your cars but require a ceiling height of at least 9 feet for safe clearance.
- Workbench Area: A basic workbench is about 2 feet deep and 4-6 feet long. You’ll need an additional 3-4 feet in front of it for you to stand and work comfortably.
Allowing For Walkways And Movement
A garage should not be an obstacle course. Safe, clear walkways are essential. You should be able to walk around your parked car, access storage, and carry items without squeezing through tight gaps.
Designate a primary walkway, often from the entry door to the interior house door. This path should be at least 3 feet wide and kept completely clear. Also, ensure you can open the driver’s doors of both vehicles fully and step out onto a clear floor space, not directly in front of a shelf or trash can.
Key Factors That Influence Your Ideal Size
Your perfect garage size is personal. It depends on your specific vehicles, your hobbies, your climate, and even local building codes. Let’s examine the variables that should guide your decision.
Local Building Codes And HOA Regulations
Before you draw a single plan, check your local building department and Homeowners Association rules. These regulations can dictate minimum and maximum sizes, setback requirements from property lines, and even the style of garage doors allowed.
Some municipalities have specific square footage limits for accessory structures. Your HOA might require that the garage matches the house’s architecture in a way that influences its footprint. Always get this information first to avoid costly redesigns later.
Climate And Seasonal Considerations
If you live in an area with harsh winters, a larger garage offers significant benefits. The extra space allows you to store snow blowers, shovels, and salt without crowding the cars. It also provides room to brush off snow and ice inside the garage before driving out.
In warmer climates, you might prioritize space for lawn equipment, gardening supplies, or outdoor recreational gear like kayaks or bicycles. The depth of the garage becomes crucial for storing these longer items along a side wall.
Future-Proofing Your Investment
Think about the next 10-15 years. Your vehicle needs may change—you might get a larger family car, an electric vehicle requiring a charging station, or a boat or trailer that needs indoor storage. Building a slightly larger garage now is far cheaper than remodeling later.
Consider adding extra electrical outlets, planning for a 240-volt circuit for an EV charger, or ensuring the door height can accommodate a future RV or van. These foresights protect the long-term value of your home.
Step-By-Step Guide To Determining Your Size
Now, let’s put this all together into a practical plan. Follow these steps to calculate the ideal two-car garage dimensions for your specific situation.
- Measure Your Current Vehicles: Get the exact width and length of both cars you park regularly. Include the side mirrors in the width measurement if they are not folded automatically.
- Add Minimum Clearances: To the total combined width of your vehicles, add 4 feet (2 feet between them and 1 foot on each outer side as an absolute minimum, but 3 feet on each side is better). For depth, add at least 3 feet to the length of your longest vehicle for front/rear clearance.
- Define Your Additional Functions: List your must-have non-parking uses. Will you have a workbench? Storage for bins? Space for a freezer? Sketch where these will go and how much floor or wall space they require.
- Create a Simple Layout Sketch: Use graph paper or a simple digital tool. Draw rectangles for your cars at their full size, then draw the storage areas and walkways. This visual will instantly show you if a 24×24 or 26×26 footprint is necessary.
- Consult a Professional: Take your sketch to a contractor or architect. They can advise on structural feasibility, cost implications, and ensure your design complies with local codes.
Common Mistakes To Avoid
Learning from others’ errors can save you time, money, and frustration. Here are the most frequent pitfalls homeowners encounter with two-car garage dimensions.
- Ignoring Door Swing: The most common complaint is not being able to open car doors. Always plan for the full arc of the door, not just the car’s static width.
- Forgetting About the Steps: Many garages have a step up into the house. This step can intrude into the parking space, making it difficult to open the door of the car parked nearest to it. Account for this in your depth measurement.
- Underestimating Storage Needs: Everyone accumulates stuff. What starts as an empty garage soon fills with tools, sports equipment, and holiday decorations. If you don’t plan dedicated storage, your cars will lose their space.
- Neglecting the Turn Radius: A garage that’s too shallow makes pulling in and out difficult, especially for longer vehicles. You need adequate depth for a comfortable turning approach.
FAQ Section
What Is The Average Size Of A Two Car Garage?
The most commonly built two-car garage is 20 feet by 20 feet. However, the recommended and more functional average size for new constructions is moving toward 24 feet by 24 feet or larger to accommodate modern vehicles and storage.
Is A 20X20 Garage Big Enough For 2 Cars?
A 20×20 garage can fit two small to mid-size cars, but it will be a tight squeeze. It often does not allow for comfortable door opening or any additional storage. For most households, it is considered the absolute minimum and is frequently inadequate.
What Are The Dimensions Of A 2 Car Garage With Storage?
For a two-car garage that includes meaningful storage or workspace, aim for at least 24 feet in width and 26 to 30 feet in depth. This allows for full-width parking clearance while dedicating the back or side wall area to shelves, cabinets, or a workbench without compromise.
How Wide Should A Garage Be For 2 SUVs?
For two full-size SUVs or trucks, a garage width of 26 to 28 feet is advisable. This accounts for the vehicles’ wider bodies (often over 6.5 feet each) and provides the recommended 2-3 feet of clearance on all sides to prevent door dings and allow for easy entry.
Can You Fit 2 Cars In A 22X22 Garage?
A 22×22 garage is a significant improvement over a 20×20. It provides much more manageable space for two average-sized cars, allowing for better door clearance and a small amount of extra storage along the walls. It’s a good compromise if you cannot build a full 24×24.
