The EzFeasy Guide to Standard Sizes, Options, and Considerations

When planning a new home or renovation, the garage often becomes a focal point, especially if you want to add a double garage. Besides providing space for two vehicles, a double garage offers extra storage, potentially a small workshop, and can even become an organised area for hobby equipment or tools.

But what size does a double garage need to be? In Australia, there are recommended dimensions and minimum size requirements to consider, plus a few key design points to ensure your garage fits your lifestyle.

EzFeasy covers everything you need to know in this article, from standard sizes to future-proofing your garage.

Double Garage Sizes in Australia

What is the Standard Size of a Double Garage in Australia?

Australia’s standard double garage dimensions typically range from 5.5 to 6 metres wide and 5.5 to 6 metres deep. This gives enough room for two vehicles with a bit of buffer space around them for easy entry and exit, especially if one or both vehicles are large. A garage of this size balances functionality and space efficiency, making it suitable for most residential homes.

How Big is the Minimum Size of a 2-Car Garage?

If you’re working within a limited area, you might wonder about the minimum dimensions needed for a functional double garage. In Australia, 5.4 metres by 5.4 metres is generally accepted as the minimum size for a two-car garage, per Australian Standard AS 2890.1. While this space can fit two cars, it’s considered snug, leaving little room for storage or additional use. For those wanting extra space for storage or a small workspace, it’s advisable to aim closer to the 6×6 metre standard.

Is 5 Metres Wide Enough for a Double Garage?

According to AS 2890.1, which outlines guidelines for off-street parking, 5.4 metres is the minimum width for a double garage to accommodate two cars comfortably. Any garage width under 5.4 metres is generally classified as a single-car garage with storage space, rather than a fully functional double.

If you have a width of only 5 metres, you may struggle with side clearance, particularly with larger vehicles. For ease of access and manoeuvrability, it’s best to stick to the standard minimum or consult with EzFeasy for design options that make the most of compact spaces.

How Many Square Metres is a 2-Car Garage?

For a standard double garage measuring 6 metres by 6 metres, you’re looking at 36 square metres of floor space. This provides enough room for two vehicles, plus additional storage for tools or a small workspace. If you have larger vehicles or plan to use the garage for recreational gear, a slightly larger garage, such as 7×7 metres, can offer more versatility and provides around 49 square metres.

Key Considerations for Designing Your Double Garage

Vehicle Size

Think about the make and model of your cars. Larger vehicles, like SUVs or 4WDs, will require more space than compact cars.

Storage Needs

If the garage will serve as a storage hub, consider adding extra space or built-in cabinetry to keep things organised.

Door Width

Double garage doors typically range from 4.8 to 5.5 metres wide. Choose based on your space and parking needs.

Access Requirements

Factor in side and rear access if you’ll need to move in and out of the garage frequently.

Future-Proof Your Garage

When designing a double garage, it’s wise to plan for future needs, like integrating electric vehicle (EV) charging facilities or adding extra storage space. Preparing now for EV compatibility means wiring your garage to accommodate a charging station or high-capacity outlets without needing retrofitting later.

Multiple power points can also be handy for other potential uses, such as a second fridge, solar battery, or power tools. For more tips on creating an electric vehicle-friendly garage, check out this helpful article.

Storage is a Premium in Today’s Smaller Block Sizes

For homes with smaller land sizes, consider going up instead of out to maximise garage storage. Increasing the ceiling height lets you add overhead racks or shelving, creating room for lesser-used items like Christmas decorations, trophies, or university textbooks. Vertical storage keeps these items accessible but out of the way, freeing up floor space and helping you make the most of every cubic metre.

When wall space is tight, think about garage doors with windows to bring in natural light without sacrificing wall storage. This allows more hanging space for long, slender items like brush cutters or bicycles, keeping the garage organised and functional. For a variety of storage solutions, check out Garage Smart.
