Getting the right size is important when planning to build or remodel your garage.A 2-car garage is a popular choice for many homeowners. When many families own two (or even more) cars, a two-car garage is helpful to keep your vehicles away from possible thieves and robberies.

Remember the news of the 4 wheels of Honda Civics being stolen? That's why you need a garage. Don't have a Civic? A garage stops people from breaking the windows and scratching the paint.

When a two-car garage is different from a regular one-car garage, what dimensions do you need? In this article, we’ll help you understand the best dimensions for a 2-car garage and everything you need to consider when building your garage. Hopefully, you can give the best protection to your cars.

Part 1: Some Common Dimensions of Two-Car Garages

Since everybody's situation is unique, there is no standard answers to the best two-car garage size. But we do have some common garage plans here:

Garage size 
(W*L ft)
Square Ft Suitable for
18x20 360 Minimum size for two-car storage. You may not open the car doors fully.
20x20  400 A rather wider size for two cars. 
22x22 484 Offer more space. Perfect for two mid-size and full-size cars. 
24x24 576 Good for two full-size sedans and SUVs.
24x30 720 Best options for pick-ups. Has much space for storage, a workplace, or a home gym.

Let's come to the selection part here.

Minimum Two Car Garage Size:

If you have two small cars like two sedans (even the full-size ones that are 18 feet long) and have no plan to put stuff in the garage, the 18*20 dimension is good for your two-car garage plan. It's narrow and has almost no storage. 

Also, you can't likely open the car door fully. If it's a large full-size or luxury car, the truck may hit the wall when you pop it.

The only benefit is it saves money! Also, if you don't have much space land left on your property, this will be the perfect option.

For Wider Vehicles like SUVs, Wagons, Minivans:

For SUVs, wagons, and vans that are about 6 feet wide, we strongly recommend a 20*20 garage plan. It fits the width body of SUVs. The doors won't hit the wall when you open them. And the car trunk won't hit the wall when you pop it. But if both vehicles are wide, you may not have much space left for storage and other activities.

For more storage space, you can get a 22*22 garage plan. 

A Longer and Wider Full-size Vehicles and Pick-ups:

For large cars, a 24*24 is a better choice. It's wide enough for two 6.5 feet width cars. Also, you can place shelves, tables, and other stuff in the garage.

Maximum Two Car Garage Size (You can expand it as you wish):

To park your full-size pick-ups and vans? A 24*30 will be awesome. No need to explain. It's just long enough to park your pick-ups. Also, you have space for storage, a workshop, or even a home office.

Part 2: FAQs about Building A Two-car Garage

There's never a standard size to your garage option. Customize it based on your situation. Take out a piece page and write down your answers to the following questions. Then, consult the construction or design team for the final draft.

What Size Are Your Vehicles?

Why do we need a garage? For the vehicles. So, the sizes of your cars decide the dimensions of the garage.

Measure the width and length of your largest and longest vehicle, ensuring it fits comfortably side-by-side with space for door opening without collisions. That's one foot at least for a slim adult. When one of your family members is strong or overweight, add extra feet to the garage if you don't him/her to be trapped in the car.

Do You Need Storage Space For Other Items?

There must be some space left after parking your vehicles in the garage. After measuring the sizes of your cars, you can think about some storage needs like bikes, tools, a mower, a motorbike, or your vacation gear (snowboard, fishing rod, etc). 

Plans for shelves, cabinets, or a workbench to maintain organization and free up home space are up to you as well.

If the expected room is not enough, consider expanding the garage before building it.

Can a 20*20 garage fit two vehicles?

Yes, it's a pretty common size that many homeowners will use. But this is applicable when your vehicles are not large. Also, the thickness of the walls matters. The ideal number will be 6 inches (and less) for a small two-car garage wall. 

Will You Use The Garage For Other Activities?

Are you up to exercising? How about doing some technical work? 

If you lift some irons and plan to build a home gym, the garage can be a good spot.

Some like carpentry works, car repairing (even tuning), or pottery-making. In these cases, a garage can be built to fit these purposes as well.

Just pay attention that any purposes will need extra space in the garage. It increases your budget.

How Much Space Do You Need To Walk?

You need to get out of the vehicle and walk out of the garage. So, you need to consider some extra room for you and everyone that gets into the garage.

If one of you is overweight, double or triple the space.

Is It Cold in Your City?

Never underestimate the power of climates. In some areas, winds, rains, and snow in the winter will make you suffer. It may freeze the door and keep you waiting outside for minutes. This is devastating.

You may need to heat the garage with some heaters mounted on the wall or ceiling. Or you can add insulation to the garage and seal windows and doors to keep the cold outside.

Both require extra space in the garage.

Do You Own Electric Cars?

If you have a Tesla or any other electric vehicle and plan to install a charging point at home, consult the company. Ask if you need to install a wall or ground connector. Never forget the exact dimensions of the equipment.

What Is The Available Space On Your Property?

Do you have enough land left on your property to build a two-car garage? If yes, just go ahead and start your plan.

Consider property constraints and setbacks. Be realistic about available space to avoid overshadowing your house or yard with an oversized garage.

Do You Need A Permit to Build A Garage?

This is a complex question. It varies based on local laws and community regulations.

First of all, call the local government for the details. See if you need to get permission from the local department.

Then, go to the community office to consult if you need their permission to build a garage.

And finally. make sure the contractor you hire is 100% qualified to build a garage.

What's Your Budget?

A larger garage costs more. We can't give you the exact cost of building a garage. Regions, seasons, duration of construction, materials, blueprint, and sizes will all affect the cost of building a two-car garage.

Consult the local contractors and ask for a price.

What's The Cheapest Way to Build a Two-car Garage?

The cheapest way to build a two-car garage is always to do it all by yourself. You need to DIY a blueprint for the garage, buy materials, get them home, and build it from the ground.

However, every step involved, except the blueprint, requires plans, patience, skills, knowledge, and techniques. You can apply to a garage blueprint found on some design software (Check Part 3 for EdrawMax, download and edit a floor plan for the two-car garage ) and edit it for free.
