If you’re planning a new build or a renovation, you’ve probably asked yourself, how wide is a 2 car garage? Determining the width for a 2-car garage involves more than simply doubling a single car’s width; functional space is a critical component. You need room to open doors, walk around, and store items without dinging your vehicle.
This guide will walk you through the standard dimensions, important considerations, and practical tips to ensure your garage meets your needs.
Getting the width right is the first step to a functional and frustration-free space.
How Wide Is A 2 Car Garage
The most common answer is 20 feet wide. This is the standard minimum you’ll see in many modern homes and building plans. However, this measurement is often considered tight by today’s standards.
A width of 20 feet provides just enough space for two average-sized sedans. You’ll be able to park them, but opening the car doors fully might be a challenge. There will be little to no room for anything else along the side walls.
For a more comfortable and usable garage, the recommended width is 24 feet. This extra four feet of space makes a significant difference in daily use.
Understanding Standard Garage Dimensions
Garage dimensions are a combination of width and depth. While width is our primary focus, depth is equally important for fitting longer vehicles or having space in front of the cars.
Here are the typical dimension sets for a two-car garage:
- Minimum/Tight Fit: 20 feet wide x 20 feet deep.
- Standard/Common Build: 24 feet wide x 24 feet deep.
- Spacious/Recommended: 26 feet to 30 feet wide x 24 feet to 30 feet deep.
The 24×24 foot garage has become a very popular choice because it offers a good balance of space and cost. It allows for two midsize cars with comfortable door clearance and some wall space for storage or a workbench.
Why The Standard 20-Foot Width Is Often Too Narrow
Relying on the 20-foot minimum can lead to a cramped garage. The main reason is the size of modern vehicles. The average width of a new car or truck has increased over the past few decades.
Consider these typical vehicle widths:
- Compact Sedan: Approximately 6 feet wide.
- Full-Size Sedan or SUV: Approximately 6.5 to 7 feet wide.
- Full-Size Pickup Truck: Can exceed 8 feet in width (including mirrors).
If you park two 6.5-foot wide vehicles in a 20-foot garage, you have only 7 feet of total space left between them and the walls. That space disappears quickly when you account for the following:
- Door opening clearance (2-3 feet per door).
- Wall studs and drywall.
- Storage items like shelves or bicycles.
A 24-foot width provides a much more practical buffer, giving you room to actually use your garage beyond just parking.
Calculating Your Ideal Garage Width
You can determine a good width for your specific situation with a simple calculation. Start by measuring the width of your vehicles, or the types of vehicles you plan to park.
- Add the full width of both vehicles together.
- Add at least 3 feet of space between the two vehicles. This allows for door opening and walking space.
- Add at least 1.5 feet of space on each outer side (3 feet total) between the vehicles and the side walls.
For example, two 7-foot wide SUVs would need: 7′ + 7′ + 3′ (between) + 3′ (sides) = 20 feet. This shows the absolute minimum. For comfort, add an extra 2-4 feet to this total, bringing you to the recommended 24-foot width.
Key Factors That Influence Your Garage Width Decision
Your lifestyle and how you plan to use the garage are the biggest factors in choosing a width. Here are the critical elements to consider.
Vehicle Size and Type
This is the most obvious factor. If you own or plan to own trucks, large SUVs, or vans, you must plan for their width. Don’t forget to account for side mirrors, which often add 6-12 inches to the total width of the vehicle.
Measure your actual cars, including mirrors, for the most accurate planning. If you are building for resale, consider the common vehicles in your area.
Door Opening and Walk-Around Space
The primary purpose of extra width is to allow car doors to open fully. This prevents dings and makes it easier to get children in and out of car seats or unload groceries.
Adequate walk-around space is also important for safety and convenience. You should be able to walk between the vehicles and the walls without turning sideways.
Storage and Workspace Needs
For many homeowners, the garage serves as a storage area, workshop, or gym. A narrow garage forces all storage to the back wall, which can then interfere with parking depth.
Extra width allows for:
- Shelving units or cabinets along the side walls.
- A workbench or tool area.
- Space for trash cans, recycling bins, or sports equipment.
- Freezer or refrigerator placement.
Local Building Codes and HOA Regulations
You cannot simply build any size garage you want. Always check with your local building department for minimum (and sometimes maximum) size requirements, setbacks from property lines, and other zoning rules.
If you live in a community with a Homeowners Association, review its architectural guidelines. HOAs often have strict rules on the appearance and sometimes the size of outbuildings like garages.
The Importance Of Garage Depth
While width gets the most attention, depth is crucial for a functional two-car garage. A garage that is too shallow can be just as problematic as one that is too narrow.
A depth of 20 feet is the absolute minimum, but it may not be sufficient for longer vehicles like crew-cab pickup trucks or full-size SUVs. With a 20-foot depth, the rear bumper of a long vehicle may be dangerously close to the garage door.
The recommended standard depth is 24 feet. This allows you to:
- Comfortably park most vehicles with room to walk in front of them.
- Have storage shelves or cabinets at the front wall.
- Install a workbench without it being in the way.
For maximum flexibility, consider a depth of 26 to 30 feet. This is sometimes called an “oversized” or “deep” garage and is ideal if you want to store a lawn tractor, create a significant workshop, or have ample storage in front of the vehicles.
Planning For Garage Doors And Interior Layout
The size and configuration of your garage doors directly impact the interior layout and usability. The most common setup for a two-car garage is a single, wide 16-foot door. However, this is not your only option.
Single Door vs. Double Doors
Each garage door style has its advantages.
- Single 16-Foot Wide Door: This is the standard. It provides a clean look and a wide opening. However, the center post is eliminated, which means the door itself is heavier and requires a robust opener system. If the door mechanism fails, both parking spots are blocked.
- Two Separate 8-Foot or 9-Foot Doors: This traditional style features a supporting column in the center. The advantages include lighter individual doors, the ability to open only one door for energy savings, and if one door fails, the other stall remains accessible. The center column does take up some interior space.
Accounting for Door Swing and Clearance
When planning your interior layout, you must consider the swing of the garage doors when they are open. Most standard sectional doors swing down and then curve back along the ceiling.
You need to ensure there is enough ceiling height so the open door does not interfere with the roof of a tall vehicle like a van or SUV with a roof box. High-lift door tracks can be installed to move the door closer to the ceiling, freeing up this space.
Cost Implications Of A Wider Garage
Building a larger garage naturally increases cost. The expense comes from several areas:
- Foundation and Slab: More concrete and site preparation.
- Framing and Roofing: More lumber, sheathing, and roofing materials.
- Garage Doors: A wider single door or additional doors.
- Siding and Finish: More exterior materials to cover the larger walls.
However, the cost increase for going from a 20-foot width to a 24-foot width is often marginal in the context of a whole build or renovation. The long-term benefits of a functional, spacious garage usually far outweigh the initial added expense. It can also significantly improve your home’s resale value and appeal.
Special Considerations And Custom Solutions
Some situations call for thinking beyond the standard dimensions.
Accommodating a Workshop or Gym
If you intend to have a permanent workspace, you need to allocate that space in your plan. A dedicated workshop area might require an additional 4 to 8 feet of width or depth.
One effective layout is to plan for a third, narrow bay (e.g., a 28-foot wide three-car garage) where the third bay is dedicated to workspace or storage, leaving two full bays for vehicles.
Planning for Future Needs
Think about your future. Are you likely to get a larger vehicle? Will you need more storage as your family grows? Building a slightly larger garage now is much more cost-effective than trying to expand it later.
Consider running extra electrical outlets, installing better lighting, and planning for insulation during the initial construction, even if you don’t finish the interior right away.
Tandem or Side-by-Side Layouts
The classic two-car garage is side-by-side. However, a tandem garage, where one car parks behind the other, is a solution for narrow lots. This layout requires careful planning for depth (often 36-40 feet) and a system for moving the front car when you need the back one.
Final Steps Before You Build Or Renovate
Before finalizing your plans, take these final steps to ensure success.
- Create a Mock-Up: Use chalk, tape, or even park your current cars in a open space with measured boundaries to simulate the proposed garage size. Open the doors, walk around, and see how it feels.
- Consult Professionals: Talk to a reputable architect, builder, or garage contractor. They can provide local insights, cost estimates, and identify potential issues you may have missed.
- Review All Regulations: Double-check building codes, zoning laws, and HOA rules one last time to avoid costly changes or violations.
Taking the time to plan correctly will result in a garage that functions beautifully for years to come, adding both utility and value to your home. Remember, when asking “how wide is a 2 car garage,” the best answer is the one that fits your specific life, not just the minimum standard.
Frequently Asked Questions
Here are answers to some common questions about two-car garage dimensions.
What is the standard size for a 2 car garage?
The most common standard size is 24 feet wide by 24 feet deep. This provides a comfortable fit for two average-sized vehicles with room for storage and door clearance. The absolute minimum is often 20×20 feet.
Is 22 feet wide enough for a 2 car garage?
A 22-foot width can work, but it is still a compromise. It is better than 20 feet but not as comfortable as 24 feet. It may be suitable for two smaller cars but will feel tight with larger sedans or SUVs. Careful parking will be necessary to avoid door dings.
How wide should a garage be for 2 trucks?
For two full-size pickup trucks, you should consider a width of at least 26 feet, and 28 feet is even better. Trucks are wider, especially with mirrors, and their doors are long. The extra space is essential for preventing damage and allowing easy entry and exit.
Can you fit 2 cars in a 20×20 garage?
Yes, you can physically fit two cars into a 20×20 foot garage, but it will be very tight. You will have little to no space to open doors fully or walk around the vehicles. It is not considered a functional or convenient layout for regular use.
What is a good depth for a 2 car garage?
A good, standard depth is 24 feet. This depth comfortably accommodates most vehicles with space in front for storage or walking. For longer trucks, SUVs, or if you want significant front-wall storage, consider a depth of 26 to 30 feet.
