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.

Michael from Medford NY

From the 3 trips we took to Sheds Unlimited to look thru their already built structures to the final 4 minutes it took to set our (14 x 26) shed on the foundation, it was nothing but a great experience! Kyle was so great with getting our design exactly how we wanted it. Nate was also great with setting our shed in place! The sheds here are really built with pride and craftsmanship and it show! If you haven't, go look thru some of the sheds on site....they are really amazing to see.

Neil & Heather from York, PA

We ordered a great quality shed from Sheds Unlimited. Not only was it the best price (after checking ~5 places) it is built to last!

Liam from Quakertown, PA

Excellent Job! Delivered as promised, very well built. The whole process went very smoothly. Thanks so much for my new, awesome, 20' x 32' garage with 10' walls, 2x6 construction, scissor truss 12' inside center ceiling height, custom window configurations, metal roof, etc.

Brian Ames from Philadelphia PA

To begin with I had great confidence in Sheds Unlimited before even meeting them or talking to them. Having a Pennsylvania German ancestry, which is not that different from the Amish, I know how hardworking this group is. Both of my parents grew up on farms and it was always work before pleasure. Sheds Unlimited did a very thorough job of making sure I got the exact shed that I wanted. They were in touch with a lot of planning questions to make sure I was happy with what I got and were very specific and detailed. And when the 2 men arrived here with the material to build the shed, I could tell right away that they were going to do a good job. One of the young men was Amish and even though he was nice and polite, he worked every single second he was here without taking any breaks. The shed was up and complete in a couple hours. The work ethic of the Amish is similar to the Pennsylvania German work ethic and they did not disappoint. And of course the shed looks great. You will be glad you hired Sheds Unlimited.

Steve Bubbenmoyer from Rehoboth Beach

I am extremely please with my 8X18 mini barn shed. The quality is superior to local shed companies and for a much better price. The two gentleman that delivered my shed went above and beyond to make sure the shed was perfect. They touched up the paint and cleaned any dirt from delivery.

Chris C. from East Moriches, NY

My husband and I looked for a new shed at many places. Sheds Unlimited was a step above the other places. Their lot is huge, and they have so many prebuilt sheds to look at. Even if you want a custom built, it makes it nice to be able to see the options in person first. The employees were all very nice and helpful, from the first time we looked, to delivery. The delivery went very smooth, and I was impressed at how easy they made it look to get my shed where I needed it. We did give the delivery guy a tip. I would recommend this company and their sheds to anyone in the market for one.

Heather Knaub from Reading, PA

What a terrific shed! It is exactly what we ordered and is very well built. Customer service was wonderful to work with. And then there was the  delivery... Absolutely AMAZING! Imagine getting a 28x14 building up narrow and twisting roads to the top of the Blue Ridge Mountains... I still can't believe the driver and "mule" managed it - but they certainly did. A couple time I closed my eyes thinking our building was a goner, but, nope it was placed perfectly. Afterward I asked the driver about it - he smiled and said only that, "this one was a bit more of a challenge."  Thank you Sheds Unlimited!

I needed a 10x16 shed placed in my backyard where a truck would not fit for delivery.  The mule was the perfect solution. On his first delivery of the day the driver caught a low telephone wire that caused some shingle damage to my shed roof.  The very next day the company had someone at my house to make the needed repairs and the shed looks great.  Love the shed and have already given SU recommendation to neighbors.  Thanks to Sergey and Austin for making the process so easy.

Eileen from California, MD

I could not have asked for a better experience from the time I ordered the shed until it was delivered the other day. The price and customer service was amazing. I highly recommend Sheds Unlimited for anyone who needs a shed.
