Choosing the Ideal Garage Size for Your Storage Needs
Is there a standard garage size for all homeowners? NO. The perfect garage size will always be tied to several factors like the purpose of your infrastructure, amount of space needed, and most importantly; the type and number of cars you own.
This means that the ideal garage size is obviously going to vary across different individuals since everyone needs enough space that perfectly suits their storage needs.
In our D-I-Y building guide we’re going to cover various garage sizes and dimensions to help you choose the best storage size for your home regardless of the number of cars you own.
Be it you have 1, 2, 3 or even 4 cars, we believe you’ll eventually find an option that suits you. Let’s cut the BS and delve into it.
Standard Garage Size For 1,2,3, & 4-Car Dimensions
Choosing a perfect garage size for your car storage is a piece of cake if you understand the ‘width’ and depth/length measurements of your vehicle.
The width of your garage is the distance measured from right to left sides facing the garage door. On the other hand, the depth is usually estimated from the front edge of a garage, to its backwall.
The typical garage depth is usually constant and accommodative across all car garage sizes except for homeowners with long vehicles which demand more space. The ideal height for garage doors stands at 7 to 8 feet, while the ceiling measurements range between 8 - 10’ from your floor.
Always keep in mind that your garage doors need to be wide enough to open for your car to get in and out freely thus avoiding scratches. There’s actually no problem having a door wider than your vehicle’s measurements because it’s actually a safety precaution.
Before we jump into detail, the table below illustrates general garage dimensions that you may consider.
Average Car Garage Size & Dimensions at Glance
|Car Garage Size||Width||Depth||Area (sq. ft.)|
|1-car||12-18 ft.||20-30 ft.||240-540|
|2-cars||20-24 ft.||20-30 ft.||360-660|
|3-cars||30-36 ft.||20-30 ft.||600-1,260|
|4-cars||20-30 ft.||20-30 ft.||800-1,680|
1-Car Garage Size & Dimensions (12' × 20')
If you’re seeking to store just a single car in your garage, there’s just a few options you can choose from. Quite straightforward!
- 12 to 16 Feet - Width
- 20 to 24 Feet - Depth
- 8 to 10 Feet - Door width
- 7 to 8 Feet - Door Height
The average garage dimensions for one car range between 12 - 16 Ft. wide, and 20 - 24 Ft. deep/long. For the garage door size, the standard dimensions should be 8 to 10 feet wide, and a height of 7 to 8 Ft. tall.
The illustrated measurements are ideal to offer enough room for a 1-car garage storage, coming with some extra space for a number of shelves or tool chest if you need to incorporate any.
If you need additional space for custom storage or luxury, we recommend you select the high-end measurements in all dimensional aspects (i.e . width, depth, & height)
2-Car Garage Size & Dimensions (22' × 20')
The two-car garage option is the most popular garage size used by homeowners in USA. Analysis has shown that most homes come with a 2-car garage.
The standard garage size for 2 cars ranges between 22 - 26 Ft. wide, and 20 - 24 Ft. deep. In this case, you’ll notice that garage door structures and dimensions begin to vary, depending on the owner’s preference.
You can choose to have either a single, double-width door frame measuring 12 - 16 ft. wide, or maybe two independent doors 8 - 10 ft. wide. In both instances, the garage door is ideally 7 - 8 ft. high/tall.
- 22 to 26 ft. - Width
- 20 to 24 ft. - Depth
- 12 - 16 ft. - Door Width
2.5-Car Garage Size & Dimensions (Two-and-a-half-car-garage)
The two-and-a-half-car garage is metaphorically used to define a bigger 2-car garage version built to shelter extra vehicles like motorbikes, or provide additional space for a workshop or storage purposes.
The standard 2.5-car-garage size is relatively larger than the 2-car garage. It measures 26 to 30 Ft. wide, and a minimum of 20 Ft. deep i.e. 26’ × 20’, 26’ × 30’, or 28’ × 30'.
3-Car Garage Size & Dimensions (36' × 24')
More vehicles to be sheltered demand a wider car garage to provide adequate storage space. The three-car garage expands in width but its depth stays constant just as the 2-car garage’s.
An average 3-car garage size measures between 31 to 36 ft wide, and 20 to 24 ft deep. It can also have either single, double-wide door or multiple doors that range between 8 to 16 ft. wide. Remember, the ideal door height is constant across several car garage sizes.
- 31 to 34 ft. - Width
- 20 to 24 ft. - Depth
- One, 8 to 10 ft. & One 16 ft. - Doors Width
- 7 to 8 Feet - Door Height
When positioning your garage doors, we advise you to put your three doors on the garage’s sides since it’s a relatively cost-effective option when compared to placing them in the front.
4-Car Garage Size & Dimensions (40 × 20')
The standard garage size for 4 cars should be 40 - 45 Ft. wide, and 20 - 25 Ft. deep. Very few people need a 4-car garage because most Americans don’t need the enormous space this garage size comes with.
It’s therefore very rare to see one in the United States homes compared to the popular 1 and 2-car shelters. It’s however an ideal option for homeowners who require extra workshop space and also individuals who need to park 4 cars.
For convenience purposes, you should park your favorite, daily rides in front of the ones you use the least.
- 40 - 45 Ft. wide
- 20 - 25 Ft. deep
