How Big is a Three Car Garage? (or how big should it be?)

What is the right size for a 3 car garage?

If you’re tired of parking your extra vehicles outside, squeezing around your spare freezer whenever you want to climb into your car, and having no extra room in your garage for your lawnmower, you may want to consider buying a three-car garage.

But how big should your three-car garage be? You might be asking. You don't want a three car garage built only to wish it had more space for things besides cars! Let me walk you through all the things you should consider when deciding on the dimensions of your three car garage.

How big is a three-car garage?

The size of a three garage can range from 20'x30' to 30'x60' but keep in mind that going with the smallest size will limit space for storing other things. You will want to consider how much space you have, how big your cars are, and what else you intend to do with your new garage space. Read on, and we’ll help you find the three-car garage size that is right for you. The one in the photo is a 24x30 Three Car Garage with attic space

Minimum three car garage size.

At the bare minimum, a three car garage is 20X30. You might choose this size if you have limited land space, and your cars are very small. Another reason you might go with the minimum size is if you need a place to park small equipment, such as lawn mowers and golf carts. However, if you want to park three cars, you should consider going for something no smaller than 24x36 or even bigger. You may be able to squeeze all three of them into a 20x30 three car garage, but it won’t give you much wiggle room or extra storage space.

The average size of a three-car garage.

Your average, everyday detached three car garage will be about 22x32, with those couple extra feet offering just enough breathing room to snugly fit your three cars. However, many people opt to go even larger, in order to comfortably give you space to open the doors without hitting the walls or the car in the next bay. It’s also handy to have extra room for bicycles, or a workbench, or storage space.

What size should my three car garage be?

The first step in deciding how big to make your garage is to look up the dimensions of your vehicles. You should leave at least two feet of space in front of and behind your longest vehicle, two feet between each of your vehicles, and two feet between your vehicle and the wall.

However, sliding in a few extra feet will make things more comfortable for everyone. A width of 36 feet will provide a nice amount of space for three vehicles side-by-side, leaving space to open doors without scratching the vehicles next to you, and room to walk around the vehicles.

Go even bigger to a 24x40 three car garage and I'm pretty sure you won't regret it later. Those few extra feet will be very nice when you need to get in and out of the vehicles sitting inside your three car garage. 

Vehicle length varies much more than width does, so the depth of your garage will vary a lot more depending on the length of your vehicles. You should also consider the size of the largest vehicle you could see yourself driving in the future, even if you don’t currently own one that is that long. The depth of a garage varies anywhere from 20 to 30 feet.

Remember, no one ever complains that their garage is too large!

Other 3 car garage size considerations

What do you want to do with your garage? How you answer this question will also help you determine how large your three car garage should be.

  • How many cars do you want to park? If you only have two cars, you can use the extra bay for your storage needs. But if you have three cars, make sure to add extra space for storage!
  • Will you need extra space to load or unload a wheelchair?
  • Do you want to add storage shelves? Where would you like to place them?
  • Do you want to add an extra freezer or refrigerator?
  • Do you want space for a workbench?
  • How much lawn and garden equipment will you need to store? Do you have a lawnmower? How about a snow blower? How many wheelbarrows do you want to store?
  • What sports do you enjoy? Your garage will be a great place to store your sporting equipment, so make sure you have space for it.

Service was excellent and the finish product speaks for itself. 12X12 maxibarn. it's beautiful.

William Knowles from Ossining NY 10562

From start to finish, dealing with Sheds Unlimited was a great experience. After visiting Gap, PA, looking at the sheds, and dealing with Ben our salesperson, we selected a 12' x 10' Classic shed. We needed to have the shed built on-site. Ben guided us through the details, James arranged delivery, and Leon and Nate delivered and assembled the shed in under 4 hours. Incredible! The shed looks great and is well made. We couldn't be happier with our purchase.

I needed a new shed to replace my old metal one that was destroyed by hurricane Sandy. Going to the local building stores they wanted a lot of money for shed that didn't look like it was constructed very well. I began looking on line for an 8 x 12 shed and came across Sheds Unlimited and am VERY happy I did! They were extremely pleasant to work with and they answered my every question regarding placement and delivery.....I knew I was going to get a quality built shed. It was delivered on time without a scratch and the young man who delivered worked very hard squeezing it between my garage and my fence to get it into my yard! I highly recommend Sheds Unlimited for anyone considering a new shed!

We have just received our Classic Woodshop Shed and it is Beautiful!

We started our journey with Sheds Unlimited with Mark Beachey; he walked us through all the different features and price points and was extremely patient with us in our decision process. He was very helpful and knowledgeable. We finally selected the Classic Woodshop Shed and started planning for its arrival. We explained to Mark that we would be traveling and that mid September would be the best time for the Shed to be delivered. Mark stated that that would coincide with their building schedule and we should have no problems getting it delivered in that time frame. Mark was a delight to work with.

We were told in an email that Austin Beachey would be handling the coordination of the delivery and to contact him via email. This is where communication seemed to break down. We sent our email, with a picture of our completed pad, and received no response. We called, to speak to Austin, and the receptionist stated that she could not locate him. We provided our phone number and email address, and were assured that Austin would reply to our phone call. After waiting a week with no response, we called a second time and attempted to speak to Austin, but we were in the mountains and the phone signal was very weak on our end. We were able to let him know that we would send a second email with pad picture to start the delivery planning. The second email was sent, with pad picture, and we received no response. After the third email, we finally heard from Austin and received a tentative delivery date of sometime the following week or the beginning of the week after. No real date was provided. Then we waited and waited and waited. At the end of the first week we sent another email query, and this time Austin responded. He said that he had responded to our most recent communications, but the email that he sent to us with the “delivery date” had gotten stuck in his draft folder. It happens. Chalk it up to electronics. We accepted that and moved on. We were given a delivery date of Monday September 25 at 2:30. GREAT! Finally the shed would be here. Got a call Monday morning on the 25th from Austin stating that the driver was going to be delayed and it was going to be closer to 4:30 pm. No problem. Shed was going to be here at 4:30 … still no problem.

Delivery of the shed: 4:30 p.m. - no shed … 5:30 – no shed. The delivery truck finally showed up around 6:30 p.m.; two hours late. That I dealt with, BUT at 6:30 at night it was starting to get dark. By the time the one and only person that delivered the shed was able to get it off the truck and onto the Mule, it was very dark. We helped guide the driver in getting the shed from the truck to and positioned on the pad. Our lot is 300 feet deep and very dark where he had to place the shed. We had to provide lights for the driver to be able to see to put the shed on the pad. Finally got the shed on the pad and situated around 8:45 pm. Our delivery driver was great and worked very hard to get the job done. We give him 5 stars.

Keys to the shed: We do not have a key to get into the shed. The driver explained that he normally has a Master Key that will open the door and allow us access to the shed's interior to get our set of keys for the shed locks and to inspect the shed. The driver did not have a Master Key to enter the shed. He stated that he had explained this fact to Austin, but that piece of information was not provided when Austin notified us of the later than expected delivery of our shed. The driver explained that, when we called to pay for the shed, we should ask to have a key delivered to us. We’ve had the shed two days, and we have yet to enter our shed to inspect it. When I spoke to the receptionist the next morning, she stated that the company is mailing us a key and it will take about 3 days; we believe the key should have been FedEx’ed overnight.

Recommendations: Have someone personally contact (not via email) the customer regarding the pre delivery and post delivery to ensure everything is on track and all parties are kept informed. This allows all parties involved to communicate any unexpected circumstances and to solve issues before they become problems. Always have two delivery drivers. Getting the shed off of the flat bed, on to the Mule, and moved to the pad is a very impressive operation, but the process is filled with moments of danger. If the delivery driver had gotten hurt, the customer would have had no idea how to give aide … Safety above all else!

The bottom line is that we will highly recommend Shed's Unlimited to friends and family; we would go back to Shed's Unlimited to purchase another shed should we need one; and we were happy with most of the process. We acknowledge that the communication challenges could have been handled better on our end. Thank you ALL for your work in planning, building, scheduling and the delivery of our beautiful new shed.

The entire process was fantastic! From designing the structure to delivery, everyone was incredibly helpful and professional. I'm thrilled with the quality of the building and look forward to using it as my studio for years to come.

I worked with Sheds-unlimited over the phone. They explained to me how to prep the site. Took about 1 day to level the ground build the base and add the stone.
The Shed showed up as promised in about 20 minutes it was off the truck and in place. What I like the best is everyone knows what they are doing at Sheds-unlimited no messing around or problems. Price was excellent and shed is extremely well built.

Custom shed is the way to go..I thought I would take advantage of a shed that was built over winter..to take advantage of the savings..not a good thing. the ridge vent was missing along with the plate across the doorway... and from being stored in the field down back all the water run-off through that area the shed was twisted the side door still is not opening the way it should. the rear 4 x 4 was hanging when it was placed on the pad and others twisted. I reported the problems and the way they talked to me this was a normal thing.. and they were fighting with the township so they could get the storage problem taken care of down back. I will have a carpenter do the repairs and install the ridge vent.. You get what you pay for. PAY THE EXTRA..I still like the shed and will get all repairs done.
