Minimum 2 Car Garage Dimensions

[field_lastmodifieddate] Sheds Unlimited Sheds Unlimited

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.

    LOVE my shed, so easy to order my custom shed. Great people and thanks so much to the guy that delivered it thru the pouring rain. He did a wonderful job!

    Sue from Hillsborough, NJ

    There was not a single interaction that wasn't outstanding with Sheds Unlimited. I was forced to delay delivery TWICE. That's an issue for a business wanting to clear space of the shed built for me, but they were VERY understanding. When they delivered, it was the exact time frame stated. The delivery guy was OUTSTANDING...like a family member the way he was concerned with proper placement. It was VERY difficult spot to manuever and he took his time, was very patient and fantastic attitude, in spite of the challenges. He wanted it to be placed correctly almost if not more than me!! He took time to talk about the shed, gave me the keys to my new structure and even allowed me to pay by credit card. Such a great person to work with and outstanding representative of this outstanding company. The shed itself is OUTSTANDING. Such fantastic quality built (12x8 Workshop). Paint is perfect, everything is perfect!! I could NOT be the price anywhere locally, even INCLUDING the additional cost for delivery, the price was still FAR lower than quotes near me. The is NOTHING you should be concerned about buying from Sheds Unlimited. I've already recommended them to a friend, who is about to order having seen the quality build. I would recommend them to ANYONE (who I liked!!). No worrys. Buy with confidence. Thank you so much Sheds Unlimited, for your quality build, your outstanding people and the pricing that you offer in these tough economic times!! All the best to you!

    Just a note to commend you and your crew for building and delivering my well built Mini-Barn. The Barn arrived earlier than contracted, thanks to Kyle. The delivery expertly handled by Levi, that man knows how to work the 'Mule'.
    Again, thanks and you can put me down as a satisfied customer.

    Sheds unlimited was a pleasure to deal with. All my questions were answered promptly by e-mail or phone call which is very rare these days. We were very pleased with the quality of the shed and the expertise of the gentleman working the mule to install it.

    Alisa fonti from Branchburg,nj

    Great experience!  Mark was great to work with.  I would highly recommend getting your sctructure from Sheds Unlimited.

    Brian from Wallingford, PA

    We had a wonderful experience with the staff at Sheds Unlimited. All were very knowledgeable, helpful and pleasant to work with. John helped us to design and customize a premier one car garage that we could not be happier with. Shane did a great job getting the shed into place and installing the finishing touches. The entire staff was top notch. The new garage really dresses up our back yard and we are so excited to use it. We highly recommend Sheds Unlimited. You will not be disappointed.

    Courtney from Morgantown, PA

    Can't say enough good things about dealing with everyone at Sheds Unlimited in purchasing our new 2-car, 2-story, 24'x30'  Maxibarn Legacy garage.  From the design, to the production and especially the construction, we couldn't have been more pleased.  Their crew of three came to install our garage four weeks earlier than planned.  They arrived at 11:30 a.m, worked until after dark, started the next day at 7:00 a.m worked again until after dark, arrived again at 7:00 a.m the next morning and were finished, cleaned up and gone by 1:30 p.m.  What was most beneficial for us, in addition to the lower cost, was that the building interval was kept to under 3 days, as opposed to having a contractor on site for months.  Couldn't be more pleased with our new garage with second floor storage!

    Charlie K. from Yorktown Heights, NY

    Superior quality and outstanding customer experience from start to finish. Everything went very smooth and we highly recommend Sheds Unlimited including their authorized foundation contractor who did an exceptional job.  Thank you

    First, I would like to say that everyone I spoke to at Sheds Unlimited was very accommodating. I needed more space in my 2 bedroom house, and I specifically needed a workspace for my growing home business, as well as an art studio. We were looking to create an alternate building in our backyard rather than live through the nightmare of adding on to our house.

    Delmar was great at working with me from the start, and ran through several different estimates with me. They did a complete interior package for my shed in knotty pine and even installed radiant electric heaters that I purchased from another company so they could be hardwired behind the paneling and not have the ugly corrugated metal wires be left visible. I also chose to add a 8'x12' loft to my 12'x22' building, and they made me a beautiful detachable ladder so it could be moved when not in use. (Although, they made it so pretty I never want to move it!) Delmar was great at making sure I got the custom building I wanted.

    Delivery was nothing short of amazing. We live in a very hilly area with tight, narrow streets. The tractor trailer couldn't even turn to get up our street, so our delivery guy loaded our shed on the mule and rode it up our steep street. Then he had to deliver it on an incredibly sloped, narrow yard. I am sure we were one of the harder deliveries he's had, but he worked at it like a trooper.

    I am extremely pleased with my art studio out back. The work was meticulously done and well-built. They installed closed cell insulation which has made the shed easy to warm up even in 20 degree weather. It took the utility company 3 1/2 weeks to get me power after the shed was delivered, and because the shed was so well insulated, I could actually work out there in a heavy coat and not freeze in 35-40 degree weather. I think the combination of insulation and wood paneling also acts as a good sound proofer as well. I live in a pretty urban area and feel like the shed is very quiet compared to our house - I don't hear the outside noises of doors slamming and people talking as much when I am in there.

    I would highly recommend this company. For the amount of space we got, we paid a lot less than we would have if we had put on an addition to our house of a comparable size. And best yet, it only had to be delivered!

    Melissa Nannen from Bala Cynwyd, PA

    Our shed came out beautiful! You did a fine job. Ordering and delivery were
    both a breeze. We are very happy with our shed and would not hesitate to
    recommend Sheds Unlimited to anyone! Many thanks to Ben Shue and the
    young man who skillfully set it in place it for making it so easy.
