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

[field_lastmodifieddate] Sheds Unlimited Sheds Unlimited
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. Whether you're looking for a three-car garage in Maine, NY or any other state, you don't want the 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 3 car detached 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.

This is the second shed that I have bought from Sheds Unlimited as I have moved twice in the last 5 years. I think the quality of the workmanship, materials and ease of ordering make them a winner every time. Pricing is as good if not better than anything that you can find at Home Depot or Lowes but the quality of the product is far superior. Thanks again for a great shed and buying experience.

It was a pleasure to deal with Sheds Unlimited.The shed was very well constructed. The delivery person was very professional and did a great job positioning the shed.Would highly recommend Sheds Unlimited to anyone looking for a shed.

Stephen McGrath from Sparta New Jersey

Our local zoning board had a ton of requirements that resulted in us changing our shed order 3 times. Sheds Unlimited was very flexible and helpful. In the end we love our shed and are happy that we went to Shed's Unlimited to get it. We highly recommend.

I purchased a 12x28 Economy Workshop Garage. At first we wanted a pre-fab garage but changed it to a build on site. It took 6 weeks to schedule delivery, but two days before deliver sheds unlimited called to reschedule. After speaking with several representatives, they were able to build my garage a day after the original date. When they arrived, my order was incorrect and missing items. It took another trip to finish. When the representative came to complete the work, he handed my fiancée a reimbursement check. Although my first impression of sheds unlimited wasn’t great, they did everything in their power to correct the situation. The garage looks great and is well built.

...except, "Thank you!" Whole experience could not have been better. Sarah took the order and it was completed exactly as placed. Delivery and set up was flawless. If we had room I'd order another one just for the pleasure of dealing with these folks. This outfit has it's stuff together from beginning to end. My only suggestion to future customers is one that was passed along (only half jokingly) to us..."Buy a size larger than what you think you need!!") Thanks, again, Sheds Unlimited!

Super sweet shed should suffice significantly, seriously!

Chip from Newark, Delaware

I began making casual inquires in January about having a 28x44 garage built and delivered all the way to Maine and from then until after the garage was built it was a 100% positive experience. Gideon was very helpful and responsive as a project manager, he answered all my questions about features & options, concrete cure times, my local building codes, and build timing. I changed my mind on the design a few times early on but that was no problem. If that wasn't enough, the day the two trucks arrived in July with my unassembled garage I was very impressed with the work crew. Like a well-oiled machine they were efficient and smooth. I should mention polite and friendly too. Three days later I had my car and truck parked inside. All my neighbors were impressed with their speed and quality. I want to thank AJ, Dani,Elmer,Gideon,Kyle and Mark for building me the workshop garage I've been wanting for 25 years. I am recommending them to everyone I know!

I just wanted to let you know how happy I am with the shed I bought from you this past summer. I purchased it to park my Harley in. I finished off the interior and just added some indoor/outdoor carpet for the final touch. Thank you so much for building and selling such a high quality shed at a very reasonable price My Harley and I appreciate it. God Bless!
