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.

I was worried that they would not be able to put the shed where i needed it. Not only did it get there, but it was put there in short order. This company has delivered a quality product on time, with professional results. I would recommend them to anyone.
That again.

Chris cassel from Cape may, NJ

Purchased a 10' x 16' semi-custom shed from Sheds Unlimited in the summer of 2013. Every part of the process was superb including the quality and delivery of the final product. Highly recommended.

Sascha Prochaska from Mendham, NJ

The crew at Sheds Unlimited were really a pleasure to work with. From start to finish all were very helpful. David answered all my questions wether it be via phone or email. He was always patient. Shane did a wonderful job on the delivery/install at my home. I woud recommend this company in a heart beat.
Thank you all very much for a job well done.

DD from Cherry Hill

We purchased a shed for our backyard, working with Kyle as our salesman. He was helpful, informative and prompt. When our site was ready for delivery, Austin arranged shipping in a matter of days. The shed was delivered and placed on site so efficiently that we were amazed.
I could not recommend Sheds Unlimited more highly. Everything, from selection to delivery, was excellent.

Sherry Bellamy from Takoma Park MD

Sheds Unlimited provided great customer service. Due to a number of issues on our end, we needed a longer than typical time for preparation of the site. They willingly worked with us on the timing of the delivery and on-site construction of our new barn-style shed. The crew arrived on time and completed the project in an amazing short time. If you are a cost and quality conscious customer - you will be happy with Sheds Unlimited.

Mary Jones from Baltimore, MD

The process to customize any one of the standard designs is ingenious. Surgey was helpfull in choosing the options and placing the doors. The delivery process went better than we expected based on the tight access to the pad.

We were extremely impressed with the precision in which Ryan  manipulated the muel.

Joe from High Bridge NJ

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 

Mark K from Douglassville, PA

We love our new shed! The company was very easy to work with. Good value for the money. The delivery at night in the rain though our tight side yard to the shed pad in the back  and perfectly aligned was amazing.
