Minimum 2 Car Garage Dimensions

2 car garage dimensions

We all like perfection. And let’s face it, most of us have less than perfect garages (or none at all!). So, when preparing for the perfect prefab two car garage to fit your needs may, the first question should be:

What are the Minimum 2 Car Garage Dimensions?

how big is an average 2 car garage

Most experts say the minimum recommended dimensions for a two-car garage is 20x20. This size two car garage will give space for two smaller vehicles. You won’t have much space for storing extra knick-knacks, but it should get the cars inside.

So what are a few challenges of buying the smallest two car garage?

  1. If you store two cars inside the two car garage, there will be very little space for the garden tools, a workbench or other accessories.
  2. The garage doors will be 8’ wide instead of 9’ or 10’. Although your small car will easily fit through the garage door, an extra foot on your garage doors can make a big difference when using the mirrors to back into the garage.
  3. The car doors might hit the walls. When you open the car doors inside the minimum sized 20x20 garage, you might just end up scratching the car door when you’re in a hurry to get in and out.

In short, the minimum dimensions for a 2 car garage should be 20'x20' and to make extra space to get in and out of the car, it is recommended to go with 24'x24' or larger.

If you want to keep your vehicle looking nice and want extra space for other things, a bit wider and deeper will go a long way.

While 20x20 is the minimum size of a two car garage, if you want to keep your vehicle looking nice and want extra space for other things, consider going a bit larger.

What is the Average Size of a Two Car Garage?

Note that there is a difference between the minimum size of a two car garage and average size 2 car garage.

Have you ever met an average-sized person? The problem with average is that no one person perfectly fits the “average” mold. It simply means a middle ground, and your needs may be above average or less than average.  

Let’s break it down the average garage size question further:

a. Width: What is the best width of a 2 car garage?

The average width of a car is around 6 to 6.5 feet. Add a few feet on either side to get in and out of a vehicle and you will soon be close to the 20-foot width of the minimum garage size. If your property has space and your township gives permission, we recommend going at least 24’ wide. You will love the extra width for getting in and out of your car when it is parked inside the garage. If you can’t go 24’ wide on your garage, a 22’ wide garage would still give you a bit more space to play with.

b. Length: How long should your two car garage be?

That all depends again on the size of your vehicle and what you hope to do inside the two car garage besides parking. Most of us want to store more in our two-car garage than Old Bessie and her sidekick. Add an ATV, a motorcycle, or even a few bicycles and your garage can quickly become crowded. Put some shelves on the walls, or add a workbench or two and watch your floor space shrink!

c. It depends on the size of your vehicle and what else you wish to store

Keep in mind that a typical sedan (here we go again) is about 17 feet long. If you want room to get around the back of your vehicle with the garage door closed you may want to go more than 24 feet deep. You might also consider adding 4 more feet for a workbench so you have space to tinker with the car inside. If you really want space to work on your vehicle inside the garage, then you should consider a 30’ long two car garage.

Bottom line, the average size two car garage is 24x24 or 24x30, but it also depends a lot on what you want to put inside. Note, we said "average sized garage," not the minimum sized two car garage.

Here are a few visual aids from Decosoup.com to help give think about what the best dimensions of a 2 car garage might be for you. It may help you decide to build bigger.

What are the height dimensions of a two car garage?

Think about this: Extra Height in your garage means extra storage space.

You might think that all car garages have a standard ceiling height. Even that is adjustable according to your needs. Note the difference here between a standard two car garage from Sheds Unlimited and a garage with attic space. Obviously, the height dimensions of the two garages are quite different and offer a vastly different amount of storage space.

However, just to keep it simple, the average ceiling height in a two car garage is about eight feet and the typical garage door is 7 feet high. If you have a full-sized pickup truck or van to store inside the garage you may need to go with a larger dimension in both two car garage and garage door size.

Keep in mind that in order to install an opener a minimum of two inches of headroom is needed above the garage door where it comes closest to the ceiling during travel. One advantage of looking at a Sheds Unlimited Two Car Garage is that most of our garages have the options of increasing the height dimensions.

Here are a few examples of the Height Dimensions of our Two Car Garages:

How to expand the Interior Dimensions of your Two Car Garage

If you only have a certain amount of ground you can cover on your property, there are several ways to get more storage space inside your two car garage.

  1. Add shelves inside the car garage for using up the wall space
  2. Increase the height dimension of the two car garage with higher walls.
  3. Install an attic truss system. The attic two car garage comes with a full sized stairway and a floor space for lots of extra storage space.
  4. Go even higher with a full second floor and even add dormers to create a garage with apartment space or a small workspace. The Legacy Two Story Garages are amazing when it comes to extra room.

Going higher gives you the same ground cover but much more interior space for whatever you want to do with it.

What is the price of a two-car garage?

We knew you'd come to that question! Everything comes with a cost, even an average size two car garage!

If you want the long answer, read out post on How much does a two car garage cost

Otherwise, here are just a few of Sheds Unlimited’s Spring 2018 prices. They may of course change without advance notice, but you can always find the updated prices online.

  • Believe it or not, you can get a 20x20 Modular Two Car Garage for only $9,105! That includes the floor, setup on your prepared pad and all. It will be ready-to-go for a very reasonable cost. They even offer 20 miles of free delivery!
  • Next step is a prefab garage built on a concrete pad. The basic cost for a 20x20 with two doors and setup with 20 miles of Sheds Unlimited will be $10,862. A 24x24 2 car garage will start at $13,278. Now that price is a basic one-story two car garage. If you want more, it will cost!
  • Attic Garages give you a lot more space for the money. A 24x24 Attic Two Car Garages comes with a stairway, 8’x24’ storage area in the attic and an 8/12 roof pitch all for $18,640. Again, that is built on a concrete pad within 20 miles. Extra mileage fees apply outside of that.
  • Think bigger and go with a two story garage. The 24x24 Workshop Two Story Garages start at $23,298. Don't miss the dormers! They create the space to build your man cave on the second floor!

In Summary, how big should my two car garage be?

The focus here should be on “my” two car garage. Since everyone’s needs are different, go as large as needed to accommodate your need. One of the most common comments people make concerning garage size is, “I wish it were bigger.” I’ve never heard anyone say their garage is too big. Think about going larger than a typical two-car garage; it will give you extra space.

you guys are the best!

everyone on the phone was great in helping us pick out the right shed and worked with us through a couple changes.

you were significantly less expensive than our local 'discount' shed stores.

your installer was super nice and nestled the shed right into a pretty tight spot in the backyard.

the shed is great and we could not have asked for a better experience.

thanks again,

Richard Stegner from Shelter Island N.Y.

Very happy with the construction of the shed. Far superior to others I looked at. They were a pleasure to work with.

David Robertson from Alexandria, VA

We have a very unique yard that slopes downward and is difficult to access. Home Depot agreed to the job back in May after looking at pictures of the yard and access points, and we scheduled delivery for July. Their crew called out the morning of the delivery and we rescheduled to August. August came, and the delivery crew from Home Depot showed up only to tell me they were not willing to do a Job that difficult. Then I found Sheds Unlimited. I worked with Ben over the phone and Gideon in the field. Gideon and his crewmember found a way to get the shed pieces down a steep embankment and assemble the shed- all in the pouring rain! This was their 2nd shed assembly of the day. I was very impressed by their hard work and the fact that they stuck with the job despite its difficulty. Thanks everyone!

I live in Flemington, NJ and we just ordered a Shed from Shed Unlimited and the entire process was awesome. We are so pleased with the service we received. The price was "unbeatable" and the installation was amazing. A one man job...incredible to see set up. Easy 1-2-3. The quality of the Shed is great. I highly recommend Shed Unlimited. Thank you for your service, the quality and everything.

Eva - Flemington, NJ

I am an artist that needed a studio/shed. After searching the web I found a local artist who had also purchased a studio through sheds unlimited. She had great things to say about her experience. I was happy with the level of service and professionalism these guys showed me. Everything from the sales end to the final delivery. It was quite a process. There were some mistakes made but the team was amazing about remedying them and delivering a shed I am thrilled with. The workmanship is beautiful and I couldn't be happier with the end result. The only drawback was I had to wait awhile but it was worth it. I would definitely use sheds unlimited again if I have the need.

Kelly M. from Carversville, PA

Two years ago, Sheds Unlimited built us a 14 x 20 cabin for our land in WV. We love it! When we needed a shed for our home in Delaware, we immediately contacted Ben Shue again and scheduled an appointment to meet with him. We explained what we wanted and again, he listened and made suggestions. As before, he understood what we were looking for and kept in our price range. The shed was ready when he said it would be. The delivery driver was awesome. He came when he said he would and he was very efficient. We have recommended Sheds Unlimited to our friends and will go back to them if we ever need another shed. Thanks to the whole team! You're awesome!

Alex and Theresa Garcia from Magnolia, DE

We received the MaxiBarn August 29, 2013 and it has been the best thing we have purchased in a number of years. It was transported to us from Gap, Pensylvania by a very professional young gentleman who knew exactly what to do to place it on the pad we provided. Nothing was disturbed on the lawn and we were very pleased with the delivery and set up procedure. It provides enough space to house my husband's lawn equipment with remaining space for other storage purposes. The maxi barn was painted per our specifications and matches the garage and house perfectly. We requested modifications for the placement of the 2 windows and doors and Sheds Unlimited was able to accomodate perfectly.
I definitely would recommend Sheds Unlimited for not only reasonableness of cost but also for their professional services and providing us with a very well built shed.
