Standard Garage Size: Diagrams & Dimensions Up To 4 Car Garages
“How big is a garage?” I started to wonder as my brother began talking about building custom shelving in his. Is there a standard garage size or at least a typical average measurement that would get us close?
Of course, what we actually did was measure his garage ourselves, but I still wanted to know the answer. I figured I’d share that here since so many of us are constantly starting projects or planning to buy a house, etc.
It’s useful information that I hope helps out a ton of people with their pre-planning stages. What you’ll see as you read through is that there are standard garage dimensions no matter the types of garages, but these sizes come in ranges.
I consider that a good thing and hope to come in at the larger end, but these ranges will give you an idea, whether you’re drawing up blueprints or wondering if you have enough space to use it as a workshop, man cave, or whatever else.
Length How Long Should A 2
In regards to length, this all depends on the size of the vehicle that you intend to park inside the garage. Consider that the average sedan is about 17 feet long and you still want extra room around the back with the door closed. With that said, you could opt for a two car garage that is 24 feet deep. However, for additional space for a work bench or storage, consider going as long as 30 feet for your two car garage.
Overall, the average size of a two car garage is 24 x 24 or 24 x 30, depending on what you will be storing inside.

Standard Garage Door Height
The height of a typical garage door is around 7 feet, but sometimes you can find the height to be up to 8 feet. This is based on the location of the house and the interior walls of the garage. Detached garages are normally 7 to 8 feet high.
On the other hand, if the garage is attached to a house, you have a connecting door from the house to the garage so the height will differ. In some cases, the upper story continues over the garage, thus increasing the ceiling height. This means the garage needs to be a little taller to accommodate the decreased floor height.
The biggest advantage of having a taller ceiling in your garage is the added space for storing gardening tools or bikes on the wall. Just make sure the tools you hang on the wall dont interfere with the floor or the garage door.
With that in mind, I will now explain the standard vehicle, garage, and door dimensions for 1, 2, 3, and 4 cars.
How Can You Calculate The Average 2

Time to know if your garage fits perfectly for parking your new and old car. Its not as hard as you imagine to determine how many square feet your garage is. In that case, lets take a trip back in time to high school and recollect the area formula, which is:
Area = Length x Width
Substitute the value of your garages length and width in the above formula to find the area of your garage.

How Tall Is A Standard 2
Of course, there is one more dimension that you might want to think about: height. This might be where you have more room to work with. You could, for example, opt for a much taller garage so that you could include attic storage space. This is a good way of working around a smaller downstairs floorplan.
Most 2-car garages are around 12 feet tall. If you wanted to have additional attic storage, then you might build to a height of between 13 feet and 20 feet.
It is obviously important that you check the height of your vehicle before you set any plans into stone.
Know The Average Garage Sizes
Once youve decided how you want to use your garage, its time to pick a size. Many homeowners think its as simple as choosing a one, two or three car garage, but theres more to it.
Theres an average garage size for each style and a couple secondary options. Knowing the space youll need is crucial before making a decision. Well help you with the sizing below.

Living Spaces Tend To Need More Room
Sometimes, people use garages for other purposed instead of storing their cars. They might want to use it as another room, maybe a powder room or an additional living room. Its always a good idea to have a room which gives your family more space to spend time in.
Moreover, one can also decide to turn it into a bedroom. Whatever the homeowner decides to do, the garage space needs to be adjusted accordingly. A standard sized garage, i.e., a 2 cars garage, might be good for a living room but not much so for a bedroom, as bedrooms usually require extra space.
Two Car Garage Dimensions With Loft
The dimensions of a typical two-car garage will not suffice for constructing a two-car garage with a loft because of the additional space required. The dimensions of the building in most floor plans are 34 feet wide, 30 feet long, and 25 feet high.
With a loft added to your garage, you will have extra space for storing household goods, tools, seasonal decorations, or even a hobby workshop. Will there be stairs leading up to this place, or will a ladder be sufficient for getting there?
When deciding whether to have a second floor, the first thing to consider is whether your structure can accommodate that additional height. Because most neighborhoods have height restrictions, you will need to research and determine how much room you can have.
Suppose you have plans to convert the second story of your garage into a living area. In that case, you need to take extra precautions with the electrical and insulation systems, as gasoline and car exhaust do not get along very well with them.
Every region has its conception of what constitutes a conventional size for garages that can accommodate two cars. This is due, in part, to the fact that the country in question has a limited selection of automobiles of varying sizes and models.
If people prefer driving compact cars, then their garages will likely be on the smaller side. When drivers are given access to larger trucks and vans, they have a greater demand for additional space because the vehicles occupy more room.

Comparing Two Car Garage Dimensions By Cost
If you are building a two car garage from the ground up, it is costly, but many find it worth it. As mentioned earlier, everything from labor and materials to permits and dimensions plays a role in the total cost.
Dimensions | |
576 | $49 |
Of course, the numbers above refer to averages. That does not mean that every 24 x 24 2 car garage will cost $28,000. It could cost more or less.
Cheaper alternatives such as modular garages can save you a small fortune. The word modular in building refers to parts that are constructed off-site and brought in to be installed.
A modular 20 x 20 two car garage could cost under $10,000. That is $9,000 less than what you would expect from having a 2 car garage built otherwise.

How Many Sq Ft Is The Average 2
The standard garage size for a 2-car garage can be 360 sq ft , 400 sq ft , 484 sq ft , 576 sq ft , or 720 sq ft square feet. In order to calculate the perfect square footage for a 2-car garage, you will need to measure out your desired space, taking into account the dimensions of your vehicles, the amount of storage space you require, and any other amenities you might want, such as a workbench or sink.
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.

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.
