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.

Hello,
1st, Sheds unlimited was very helpful meeting the various and extensive requirements of the township.
2nd, The garage was delivered on time exactly as ordered - there were no mistakes.
3rd, The final location of the garage wasn't the easiest to get to but they did a great job, including anchoring it to the pad.
Finally I am very happy with the quality and build.

Chuck from Havertown, Pa

My husband and I shopped many places in our area for a shed-screenhouse combo, but no one built them. We were in Pa in November, and visited the shedsunlimited location in Gap. David was very helpful and gave us lots of information to look at. We got our combo last week and it was everything that we wanted. They have done an excellent job, it is great. Everyone that I spoke to during the process was very nice to deal with and the delivery person was great. We couldn't believe one person could move a 12x24 shed by himself. We would do business again with this company and would refer friends too.

Shopped around and this was the best deal out there. Shed was built to last. Had to wait for delivery but it was worth it!! Very pleased with customer service.

Joe S. from Bel Air Md.

I bought the small A frame coop on a trailer with the electric package. I wish I would have remembered the automatic door. It would have made it all perfect.he quality and workmanship is impressive. The delivery was timely and the men were very accommodating. I need a large shed and I will use this company again.

Rose Turner from Carmel

We purchased a 10x16 classic shed with upgraded features such as pressure treated flooring, ridge venting 6ft door and an additional 3 ft side door.

The overall process from the website to the sales team was flawless. The website prepared us when it came time to select all the options. The sales team took us to the next level with their expert help with design, color selection and delivery. The delivery was on time and the 1 man operation was incredible. Daniel set up our shed in a very tight situation without any damage to the shed and surrounding property. Overall, it is a good product with good service and is the reason why I returned after 10 years. My only complaint has to do with the scheduling group. They placed 2 sheds on the truck with my shed delivered first but installed on the truck second. Daniel had to remove 1 shed to get to mine and then replace shed #1 back onto the truck. This did take up time which was unnecessary. I kept this at 5 stars since this did not impact my delivery but it did impact Daniel and his ability to remain on schedule for the next delivery.

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

The price was the main reason I picked Sheds Unlimited to begin, and was worried that the quality might be lacking. They brought the shed early, which really helped me out, and it looks great - very sturdy.

Lowell from West Chester, PA

I work with a lot of contractors and companies in both my day job and side job and there is nothing worse than the ones that need to have their hands held through the process. Sheds Unlimited was definitely not one of those kinds of companies. I told them what i wanted once and that is exactly what showed up at my house. When i did have to speak to the reps (Mark L. and Austin) it was very easy as they knew exactly what they were doing. The greatest part of my experience is when i placed my order I asked Mark if there was any way this could be a priority order, and he told me he would make a note for manufacturing that i needed this ASAP, and when Austin the man in charge of shipping called he referred to this note, and my shed was delivered weeks early. The prices were also great for the amount that came with the shed. I found my shed was about 100-200 more then competitors basic models, but the competitors were just basic and primed. My shed came with 2 windows, 2 sets of doors, paint and shutters, so i was very happy to pay this amount.

Thanks Sheds Unlimited!

Justin Johnson from Mantua NJ
