At A Plus Garage Doors, we’ve worked with homeowners all over Utah and Nevada to match the right door and layout to their garage space. Let’s take a closer look at the most common garage sizes (from a single car garage to a 2 car garage and 3 car garage) and how to choose the right one for your needs.
Why Garage Dimensions Matter for Homeowners
More Than Just Parking: How You Use the Space Matters
Most people think of garages as places to park their cars, but they often do much more. They’re a place for storage, home gyms, workshops, and even hangout zones. That means the right garage dimensions should take more into account than just the size of your cars.
Planning for Storage, Workbenches, and Future-Proofing
Adding extra width or depth to your garage can give you space for shelving, bikes, tools, or even a deep freezer. And if you think you might upgrade to a truck or SUV later, planning now for additional space in your 3 or 2 car garage can save you frustration (and construction costs) down the road.
What Are Standard Garage Size Guidelines?
Overview of Common U.S. Garage Sizes
- Single Car Garage Size: ~12 ft wide x 20–24 ft deep
- 2 Car Garage Dimensions: ~20–24 ft wide x 20–24 ft deep
- 3 Car Garage Dimensions: ~30–36 ft wide x 20–24 ft deep
These are averages, and actual sizes vary based on vehicle types and homeowner preferences.
Factors That Influence Garage Design in Utah
Utah homes often need extra space for winter gear, all-season tires, or ATVs. Many Utah homes also need their 2 car garage to have space to house multiple family-size cars, so average sizing takes that into account. Plus, local zoning, lot size, and HOA rules can influence your final layout. It’s always smart to consider how much space you actually use, not just what fits on paper.Â
Ideal 2 Car Garage Dimensions
Minimum vs. Comfortable Width and Depth
While a 20′ x 20′ garage technically fits two vehicles, it’s a pretty tight squeeze. A more comfortable size is 24′ wide by 24′ deep, which allows for easier door opening, movement, and even some storage on the sides.
Headroom and Ceiling Height Considerations
Standard garage ceilings are usually 8 feet high, but taller ceilings (up to 12 feet) can accommodate storage lifts, larger garage doors, and vehicles with roof racks or rooftop tents, ideal for trucks or lifted vehicles common in Utah.
Common Layout Mistakes to Avoid
Avoid placing storage right where doors open, and leave at least 2 feet of clearance around parked vehicles if possible. It’s also smart to think about garage door size: double doors typically need a 16′ opening, while two single doors each require 8–9 feet.
3 Car Garage Dimensions: When You Need More Room
Standard Size vs. Oversized Options
Obviously larger than a 2 car garage, a typical 3 car garage starts at 30′ x 20′, but most homeowners prefer 36′ x 24′ or even wider for extra maneuverability and space. Some opt for a double bay and a single bay combo, which adds versatility and is great for toy storage.
Pros and Cons for Families and Hobbyists
More space means more flexibility for storing tools, bikes, or even creating a small workshop. The trade-off is a higher construction cost, but for growing families or hobbyists, the benefits often outweigh the expense.
Single Car Garage Size: Compact but Practical
Dimensions That Work for Small Cars
The typical single car garage size is 12′ wide by 20–24′ deep. This is enough for most sedans and compact SUVs, though it can be tight for full-size trucks.
Best Use Cases for Single Car Garages
Single garages are great for narrow lots, rental units, or detached garages used primarily for storage. They’re also a good option when paired with carports for flexible vehicle storage.
Designing a Garage That Fits Your Lifestyle
Vehicle Types, Storage Needs, and More
Do you have oversized vehicles? Do you need to store tools, seasonal gear, or even recreational vehicles? These factors will help you determine whether a standard or custom garage layout is best, or whether you should opt for a 2 car garage, a 3 car garage, or something different entirely.
Attached vs. Detached Layout Considerations
Attached garages offer convenience and are mostly the norm, while detached garages can provide quieter, more flexible use of space. Both options can be built to fit a 2 car garage or more, just be sure to plan for utilities and access in either configuration.
