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.

Sheds Unlimited installed 3 sheds for our family over the past 4 years in two locations. Our first two sheds were delivered pre-assembled, while our most recent purchase was a build on site. All three sheds turned out great with high quality craftsmanship and friendly reliable delivery/installation. Accordingly, we'll never go anywhere else should we ever need another shed - great job Sheds Unlimited!

Ed & Lauren from Alexandria VA

Responsive on the phone, and courteous. I priced out a bunch of home office sheds--can't even tell you how many I checked out. I wound up ordering one of the in stock ones, and I can't be happier. Quick delivery, careful placement of the shed, and the price was great. It is literally like another room in your house--complete with insulation, electric, house-grade windows...even light bulbs. Definitely recommend!

Stacy Carey from Long Island, NY

I bought a garage from Sheds Unlimited a year ago, and I am still very pleased. Everything was just as I had specified. They were very easy to work with, and the price was competetive.
Even though it was a large ('24 x '48) building, their crew had it up in a day. Even our county buulding inspector commented on the quality of the workmanship. Everyone who sees my garage loves it.
Sheds Unlimited is an honest, concientious firm. I would reccomend them to anyone!

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. 

Mike from East Berlin, PA - Lake Meade

Dealing with Sheds Unlimited was a great experience from start to finish.   The customer service from sale to delivery was incredible.  Kyle was  highly responsive to emails and phone calls through the entire purchasing process.  The same goes for AJ in coordinating the delivery of the shed.  The delivery person was friendly and did a great job getting the shed through a tight opening.

The quality and price of the shed was excellent.  I would highly recommend Sheds Unlimited.  Thanks for a great purchasing experience. 

Jason from Morrisville, PA

My wife & I recently bought a "home office" shed from Sheds Unlimited.  We were very pleased with the entire experience.  Our sales rep (Ben) was excellent, taking us step by step through the process (which was very simple).  The shed itself is very sharp & well made, precisely to our specifications.  All of their people we met (the men who installed the pad and the delivery driver) were professional, courteous and very good at what they do.  We heartily recommend Sheds Unlimited.

Vicki & Terry Kehr from York, PA

Great experience working with this company. I contacted Sheds Unlimited on 9/26 needing a shed. It was delivered on 10/6. The customer service rep was very help in selecting a shed within my budget. I would recommend Sheds Unlimited.

Karyn Lasky from New Egypt, NJ

This was one of the best decisions I made was to have a shed built by Shedsunlimited. Everything went smooth, and the shed was built on site and it turned out just great. Neighbors stop by and comment how great it looks and how it compliments our home and property. The workers were hard working and hardly stopped at all until it was finished. They cleaned up all the debris and painted the nail holes and touched up where needed. If you are looking for a quality shed or garage look no further than SHEDSUNLIMITED, and believe me I am a critical person and I was amazed at the end result.
