Whats The Average Garage Size
The answer to this question varies.
There are no standard garage dimensions. Still, many homeowners think the answer is as simple as a one-car , two-car, or three-car garage.
But this can vary, too. And you certainly want something wide enough to get in and out and open your car door!
A one-car garage is clearly the smallest choice. On average, a one-car garage is 12 feet wide and 22 feet deep. Other common sizes are 14 x 22 feet, 16 feet x 24 feet, and 14 x 24 feet. These bigger one-car garages are great for storage space in addition to the space for your vehicle.
Two-car garage dimensions are generally 18 feet wide by 20 feet deep. But, if you want space to fully open the doors of the car, or you want more storage area or a workspace, there are other common sizes, including 20 x 20, 22 x 22, and 20 x 22.
Three-car garages are the most spacious and provide ample parking and storage space. Some homeowners choose to renovate one of the garage areas into a living space, a bedroom, or even a rental unit. These garages are usually 32 feet wide by 22 feet deep .
Depending on the area you have to work with, a garage builder can make the garage for you at any of those average sizes. Some builders also offer custom-built garages that fit your unique size and shape needs.

Is Your Garage Big Enough Let’s Do The Numbers
Park your Ford Explorer in the garage with at least one foot between it and the garage door. That leaves about 30 inches in front of the vehicle if your garage is 20 deep. Subtract 25 for the workbench and you now have 5 to spare. My advice? Stay slim. REALLY slim.Now, lets park your Ford Explorer in a 24 deep garage. With the same one foot between it and the garage door, you have about 4 1/2 feet between the front bumper and your workbench. But, you say, Ill just back my car out of the garage when I need to do some work? Why not choose a 2 car garage plan that allows enough room to actually walk from one side of the car to the other, without opening the garage door?
Do I Need A Permit For A Garage
Each city or region sets its own rules, but they are pretty straightforward when it comes to building a garage. The garage might need to be constructed from fireproof materials, or the electrics and plumbing might require a permit.
In some areas, it depends on the size of the garage. In some local zoning departments, single-car garages dont need a permit, but double-garages do.
Your structure needs to be single-story, less than 750 square feet, minus a roof deck, and with beams spanning 14 ft or less to qualify for a subject-to-field-inspection permit.
If the garage meets all these requirements your garage complies with the planning laws.

The Next Steps To Get A 2

Now is the time to get started!
Car Garage Dimensions: Wall Height

A common wall height in a two-car garage is 8 feet. An overhead clearance of 8 gives the interior of the garage a nice feel that is not too cramped. You may be able to go higher in some cases, however, youll soon begin to run into height restrictions for delivery if youre planning on buying a modular 2 car garage. Shippers of modular garages need to keep the height of the building on the trailer under about 13 6 to be able to pass under bridges and overpasses. So if you want a wall height that is much higher than 8 when it comes to your 2 car garage dimensions, youll probably need to go with a prefab or stick-built garage rather than a modular garage.

How Wide Is A 3 Car Driveway
If you are going to have three-car traffic on your driveway, then the width of 16 feet will not do anymore. You should instead go for extended driveways that can even allow you to turn around and even drive backward through your yard. For such the three-car driveway, a width of at least 30 feet would do. It is optimal to go for 40 feet if you can afford it.
A 25 Car Garage Is Around 500 Square Feet
A 2.5 car garage, not surprisingly, is bigger than a 2 car garage. Its around 500 square feet in total, which means it has an extra 3 feet of width and one more foot of height than a standard 2 car garage.

Is There A Cheaper Alternative
Technically, you can go below 20 x 20 and opt for 18 x 20 for a two car garage, which saves money but is not ideal. Here are a few quick numbers to refresh on before considering an 18 x 20 garage:
- 6-6.5 car width
- 1-3 feet width when opening car doors
- At least 10-12 space between each car
An 18 x 20 2 car garage simply does not have enough space to comfortably fit 2 cars. Unless you have two exceedingly small cars and no need for storage, 18 x 20 is just not enough.
Another thing to consider is that depending on your car length, the garage door clearance may not be enough. To put it simply, the only way you could fit 2 cars comfortably in an 18 x 20 is if the cars are small. That, and If there is enough space between the car and the garage door.
You need about 2 6 of space between your car and the garage door. Otherwise, most garage doors will not shut because their sensors wont allow it without the proper spacing.
Choosing 18 x 20 over a 20 x 20 is only a few hundred dollars difference and is not worth it if you need space.
Can You Fit Two Cars In A 20 X 20 Garage
It is possible to park two cars inside a garage that is 20 feet long and 20 feet wide. There will be no room for anything else, and there is a possibility that you will not be able to open your doors all the way. Despite this, both cars should be able to be parked without any additional difficulties.
Once you have determined how big your two-car garage needs, other decisions must be made. Because of this, things can quickly get complicated because you must consider regulations, building codes, and neighborhood constraints.
After determining the size of the garage you want to construct, the next step is to conduct research to identify the best building plan and obtain the necessary permits.
It is also the time to determine if you want to build it yourself or hire a construction company to do the work for you. If you want to build it yourself, it is time to make that decision.

Do You Need A Workshop
If you are like me, the answer is simply yes when it comes to a workshop out in the garage. More storage? Yes. More room for tools? Double yes! With my standard two car garage size, I find myself having to back one or both vehicles out when I am working on something. A third stall for a workshop or extra storage is a functional option worth entertaining.
What Is The Best Width Of A 2

A cars width is typically between 6 and 6.5 feet of space. You will need about 20-foot width of the minimum garage size if you provide a few extra feet on either side to enter and exit a vehicle. If there is room on your property and your township approves wide garages, we advise going at least 24 wide.
When your automobile is parked inside the garage, you will appreciate the extra width for entering and exiting the vehicle. A 22 broad garage would still provide you a little more room to work with if you cant go 24 wide.

How To Measure Your Garage Door
If youre considering purchasing a new garage door, were happy to visit and measure your door to ensure youre looking at the right options. But, if youre the do-it-yourself type, here are step-by-step instructions for measuring your garage door and ensuring your garage can accommodate an opener and the door in both the open and closed positions.
1. Measure the width and height of the door opening called the rough opening to the closest inch. This will be approximately the same size as your door.
2. Measure the space to the left and right of the opening called the sideroom. Most vertical track systems require 3.75 inches on each side. Some systems require even more space, at 5.5 inches.
3. Measure the distance between the top of the opening and the ceiling called the headroom. Standard systems require 12 inches of headroom, and most openers require an additional 3 inches of clearance.
4. Measure the distance from the garage door opening to the back wall of the garage called the backroom. You will need backroom equal to the door height plus 18 inches, possibly more based on opener installation.
The Minimum 2 Car Garage Dimensions
A two car garage is a garage that fits exactly two cars without leaving much space for much more. If all you do in the garage is park and go, this may be a perfect option for you. Remember that it also does not leave any extra space for storage.
The recommended size for a 2-car garage is between 18×20, 20×20 and 22×22. These dimensions offer very little room for movement, storage, or much else. Two small-sized cars will fit, but you will have to provide space elsewhere for your work tools, a bench if you desired one, and other items.
If you prefer smaller doors for your garage, a two car garage may be a good fit for you, but who likes small garage doors? The bigger, the better in most cases. Why would you choose 8 doors when you can get 9 or even 10 garage doors? Larger garage doors are also easier to operate when getting in and out of the garage. But remember, the right size for your needs will depend on the activities you plan to carry out within your garage.
This small-sized garage may not offer enough space to let you open your doors as widely as you would want to. You will need to be extra careful when navigating inside.
But why would anyone subject themselves to this when you can get a longer and deeper garage? A 24×24 garage is only slightly longer and deeper, but its functionality is epic.

Three car garages are usually 32 feet wide by 22 feet deep. Much like 18 x 20 2 car garages, 32 x 22 feet snugly fits 3 cars. Your other, larger options include 36 x 25 feet, 38 x 26 feet and 40 x 30 feet.
/2 Car Garage Dimensions
When you want a wider space, go for a 2 and ½ garage dimension. This is more than enough to make the garage a workstation on free days and to install storage and hanging cabinets in the garage. The wider it is, the better it is for your cars to breathe and make it look better.
A 2 and 1/2 garage car garage dimensions, for car owners, is defined as between the dimensions of a two-car garage and a three-car garage. This means that it is between 24-30-ft in doorway width and not less than 40-50-ft in terms of depth. Given this, it would also require greater space in the home.

Picking The Perfect Garage Size
This is a lot of information to sift through, but hopefully, this helps you plan out your garage transformation.
Even if your homes garage is an odd size, knowing the standard garage sizes can help save time planning for your garage upgrades.
In my mind, the bigger garage you can afford, the better. Even if you dont have enough cars to fill it just yet, youll have enough space to convert one of the bays into a workshop or extra storage for tools and seasonal items.
Theres nothing wrong with getting a larger garage than you need. I guarantee youll find a use for the extra space.
What Is The Ideal 2

This is the point where preference, interest, and perspective come to play for homeowners. Selecting the ideal 2-car garage size is solely your decision to make. Theres no perfect garage size you have to go for whichever measurement you feel will house your cars comfortably and be helpful for other purposes.
A 20x 20 two-car garage is considered the smallest of all 2-car garage sizes. This size will comfortably sit a single car or two small cars without extra storage space. For instance, a 16.5ft long X 6.5ft wide Ford explorer SUV and 16ft long X 6ft wide pickup truck will sit comfortably in a 20 by 20 2-car garage. But there might not be enough space for other things.
A 24 by 24 two-car garage will not only house these cars comfortably but also provide enough room for other purposes. Heavy-duty trucks and other giant-sized vehicles will do well in a 24 by 30 2-car garage.
So, what you consider ideal may not be suitable for another person. Thus, its best to go for your preference to avoid wasting resources or constructing something you wont enjoy in the long run. Lets quickly whats worth considering when selecting the ideal 2-car garage:
