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 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.

Wiring with Sheds unlimited was wonderful! They made the shed buying process so easy seamless. I would highly recommend them! The shed is a very nice quality. I am very happy with my purchase!

Susan Omeara from PA

Great dealing with Sheds Unlimited. Visited the new site and saw the quality of work which was the same in the shed that was delivered yesterday, great. The delivery person was wonderful. Very friendly and knew what he was doing and how to get the shed in place. Dealing with Mark and Austin was so easy. They knew all the answers to the questions I had. I will deal with them if I need another shed.

Kim from Worcester, PA

The shed is absolutely beautiful. We ordered a 12 x 10 stock shed which was delivered on time and as advertised did not leave any marks in the lawn. The shed even came complete with a lock on the door. Nothing to do other than enjoy the shed. It is very roomy and well built and holds more than you think it would. We would recommend Sheds Unlimited to anyone!!!!

Angelo Cirinelli from Fairfield, NJ

We were impressed with the level of service. The construction process was very fast and only took two days from start to finish, The quality of the 20X32 garage is excellent and we would recommend Sheds Unlimited.

Ted Currier from Center Valley, PA

Delivery was on time , price of shed was well below competitors prices, delivery men were able to place our shed where other companies would not even try, I would highly recommend Sheds Unlimited!!

Tom Harwood from Frederick

Very satisfied with this shed. Ordered a 10'x18' workshop unit and am 100% happy with the product. Order process was easy and the phone rep was very helpful, and once delivered the delivery man was able to route the 10' wide shed through a narrow 11' space between house and fence, and place it dead center on the stone pad. Good luck finding a cheaper manufacturer for an equal quality product; I couldn't. Would recommend these guys to anyone.

Jason N. from Red Bank, NJ

If you get your shed or garage from anywhere else, your not gonna be happy! Sheds Unlimited is the only company that I would deal with. I had them come to my house and build me (in 3 days!) THEE most beautiful, (made to my specs) 24x32 garage with two 24' dormers upstairs. Even THEY were so impressed with their work, it's featured in their "Legacy" line of Garages. Later, I ordered an adorable Chicken Coop. I couldn't be happier! Their craftsmanship is second to none, they are on time, polite and totally professional. You will not find this from your local builder! Thank you SO much!!

Kenny Strain from NJ

Ordering was easy. Delivery was easy. Great experience. Thanks!

marty from Pearl River, NY

Love my new shed. It was delivered last week. I thought I bought it too big, 8x14, but it's already filling up. It was delivered exactly on time. And what a master that young man is. He maneuvered those tight spaces and around a tree, it was a real pleasure to watch. And he did it in the rain, never losing his cool, and positioned the shed exactly where it was supposed to go, amazing. Again, I love my new shed, and it was great doing business with you. Much success to you.
