If you’re planning to build or buy a home, a key question is how wide is a two car garage. The interior width of a two-car garage must provide enough space for both cars and room to open their doors comfortably. Getting this measurement right is crucial for daily convenience and protecting your vehicle’s paint.
This guide will give you the standard dimensions, explain why extra space matters, and help you plan for your specific needs. We’ll cover everything from minimum building codes to ideal layouts for storage and workspaces.
How Wide Is A Two Car Garage
The standard width for a two-car garage is 20 feet. This is the most common size you’ll find in modern home construction. It’s designed to fit two average-sized vehicles side-by-side.
However, 20 feet is often considered a minimum. Many homeowners and builders now prefer a width of 22 to 24 feet for a more functional space. This extra few feet makes a significant difference in usability.
Here are the typical dimensions for a standard two-car garage:
- Width: 20 feet (minimum) to 24 feet (recommended).
- Depth: 20 feet (minimum) to 24 feet (common for trucks/SUVs).
- Door Width: Two single doors at 8-9 feet each, or one double door at 16 feet wide.
Why The Standard Width Is Often Too Narrow
A 20-foot wide garage leaves exactly 10 feet of width for each vehicle. The problem is that most cars are over 6 feet wide. A midsize sedan like a Toyota Camry is about 6.1 feet wide, and a full-size SUV like a Chevrolet Tahoe can exceed 8 feet.
When you park two 6-foot wide cars in a 20-foot garage, you have only 8 feet of total remaining space. That’s just 4 inches of clearance on each side of each car. This makes it very difficult to get in and out without dinging doors on the wall or the adjacent vehicle.
For comfortable use, you need additional clearance. Most experts recommend at least 2 to 3 feet of total space between the two vehicles. This allows you to open car doors fully and move between the cars. That’s why the 22 to 24 foot width is becoming the new practical standard.
Key Factors That Influence Your Ideal Garage Width
Your perfect garage width depends on more than just your cars. Consider these factors before finalizing your plans.
The Types Of Vehicles You Own
List your current vehicles and their widths. Remember to plan for future purchases. Trucks, SUVs, and vans are consistently wider than the cars of 20 years ago. If you own or plan to own larger vehicles, you need more space.
- Compact Car: ~5.8 to 6.2 feet wide.
- Full-Size Sedan: ~6.2 to 6.5 feet wide.
- Midsize SUV: ~6.5 to 7.5 feet wide.
- Full-Size Truck/SUV: ~6.8 to 8.2 feet wide.
Local Building Codes And HOA Regulations
Always check your local building codes first. They set the legal minimum dimensions for structures. Your city or county may have specific requirements for garage footprinnt and setbacks from property lines.
If you live in a community with a Homeowners Association (HOA), review its covenants. HOAs often have strict rules about exterior aesthetics, including garage door styles and sizes, which can impact your design.
Need For Additional Storage Or Workspace
Do you use your garage for more than parking? Many people need space for bicycles, lawnmowers, tools, shelving, or a workbench. Each of these items requires additional floor space or wall space that must be accounted for in your width and depth.
A workbench is typically 2 feet deep. You’ll need another 3 feet of clearance in front of it to work comfortably. This can easily consume 5 feet of your garage’s length or width.
Step By Step Guide To Measuring For Your Two Car Garage
Follow these steps to determine the right width for your specific situation.
- Measure Your Vehicles: Get the exact width of both cars, including the side mirrors if they are not folded. Measure from the widest point.
- Add Door Swing Clearance: Determine how wide your car doors open. Add at least 2 feet to each vehicle’s width to account for door opening. This is the “parking bay” width needed per car.
- Calculate Total Vehicle Space: Add the two “parking bay” widths together. For example, two 6-foot cars needing 2 feet of door swing each would require: (6ft + 2ft + 2ft) + (6ft + 2ft + 2ft) = 20 feet total. This shows how a standard 20-foot garage provides zero extra walkway space.
- Factor In Walkways And Storage: Add 1 to 2 feet of space between the two parking bays for a walkway. Also, consider if you want storage along the side walls. Each set of shelves or cabinets can be 1 to 2 feet deep.
- Finalize Your Ideal Width: Combine all these numbers. Using the example above, adding a 2-foot walkway between cars brings the ideal width to 22 feet. Adding 1-foot deep shelves on each side wall brings it to 24 feet.
Comparing Single Vs Double Garage Door Options
The width of your garage opening is just as important as the interior width. You have two main choices.
Two Single Doors
This traditional option features two separate 8-foot or 9-foot wide doors. Each door operates independently.
- Pros: Better seal against weather, can open only one door for energy savings, often a classic look.
- Cons: The center column (mullion) takes up space and creates a visual barrier. It can be a tight target when driving in.
One Double Door
A single, wide door, typically 16 feet wide, that opens as one unit.
- Pros: Provides a completely clear opening, making it easier to center the garage and drive in. Modern look.
- Cons: Can be less energy-efficient as you must open the entire wide door. May require a heavier-duty opener.
The trend strongly favors single double doors for their convenience and cleaner appearance. Ensure the door width is at least 16 feet for comfortable access.
Common Mistakes To Avoid When Planning Width
Learning from others errors can save you time, money, and frustration.
Ignoring Future Vehicle Purchases: You might own compact cars now, but your next vehicle could be a pickup truck. Building to your current needs without considering the future is a common pitfall. Always build with some extra capacity.
Forgetting About Wall Thickness And Interior Finishes: The stated width of a garage (e.g., 24 feet) is usually the interior clear space. The foundation and framing will extend beyond this. Also, if you add drywall, insulation, or wall panels, they will slightly reduce the interior clearance. Discuss “finished interior” dimensions with your builder.
Overlooking The Space Needed For Door Tracks And Openers: The garage door opener and the tracks the door runs on intrude into the ceiling space. For a double door, the center-mounted opener can hang down and limit overhead storage or the ability to park a tall van. Side-mounted jackshaft openers solve this problem but cost more.
Not Accounting For The Human Element: People need space to walk, carry groceries, and get children in and out of car seats. Cramping the design for the sake of saving a few square feet of foundation will make you regret it every single day.
Optimizing A Narrow Two Car Garage
If you already have a narrow garage (like 20 feet), these tips can help you maximize the space.
- Install Vertical Storage: Use the walls for shelves, cabinets, and pegboards. Get items off the floor.
- Use The Ceiling: Install overhead racks for storing seasonal items like holiday decorations or camping gear.
- Define Parking Zones: Use floor tape or parking mats to mark where each tire should go. This encourages consistent, straight parking to maximize the available space between vehicles.
- Add Door Protection: Install side wall padding or “door guard” systems where the car doors are most likely to make contact. This protects both your car and the wall.
- Consider A Car Lift: If ceiling height allows, a lift lets you stack two cars vertically, effectively turning your two-car garage into a four-car garage. This is a major investment but a ultimate space-saver.
FAQ: Frequently Asked Questions
What Is The Minimum Width For A Two Car Garage?
The absolute minimum width, often set by building codes, is 20 feet. However, this is very tight and only suitable for two very small cars. It does not allow for comfortable entry and exit or any storage.
Is A 24 Foot Wide Garage Better Than A 20 Foot One?
Yes, in almost every practical way. A 24-foot wide garage provides the extra space needed for modern wider vehicles, door clearance, walkways, and side storage. The additional cost during construction is relatively small compared to the long-term utility and convenience gained.
How Much Space Should Be Between Two Parked Cars In A Garage?
You should aim for at least 2 to 3 feet of space between the sides of two parked cars. This gap allows passengers to get in and out comfortably, provides a walkway, and significantly reduces the risk of door dings.
Can A Two Car Garage Fit Two Trucks?
It depends on the garage size and the trucks. Two full-size pickup trucks, which can be over 8 feet wide with mirrors, will not fit in a 20-foot garage. They would require a minimum of a 24-foot wide garage, and even that would be snug. A 26-foot width would be more appropriate for two large trucks.
What Is The Standard Depth Of A Two Car Garage?
The standard depth is 20 feet, but 22 to 24 feet is increasingly common. This extra depth is needed for longer vehicles like crew-cab trucks and SUVs, and to have space in front of the cars for storage bins or freezers.
Final Recommendations For Your Project
When planning your two-car garage, prioritize space over cutting costs. The few thousand dollars saved by building a 20-foot wide garage instead of a 24-foot one will feel insignificant compared to the daily annoyance of a cramped space.
Here is a final checklist:
- Aim for an interior width of 22 to 24 feet.
- Choose a depth of 22 to 24 feet for modern vehicles.
- Select a 16-foot wide single double door for easiest access.
- Verify all dimensions with your builder as finished interior measurements.
- Plan for wall and overhead storage from the beginning.
- Always check local building codes and HOA rules before finalizing plans.
By understanding the answer to “how wide is a two car garage” and planning beyond the bare minimum, you’ll create a functional space that protects your vehicles and serves your family’s needs for years to come. Taking the time to measure carefully and think about your lifestyle will result in a garage you can actually use, not just a place to cram your cars.
