Choosing the right carport size is one of the most important decisions for Australian homeowners. A carport is not only a place to park your vehicle. It affects how your driveway works, how your home looks, how easily you can move around the property, and whether the structure will meet your long-term needs.
For many homeowners, the first question is simple:
Should I choose a single carport or a double carport?
The answer depends on your driveway size, number of vehicles, vehicle type, local weather, council requirements, budget, and how you plan to use the covered space in the future.
In this guide, we compare single and double carports in Australia, explain typical size requirements, and help you decide which option is right for your home.

What Is a Single Carport?
A single carport is designed to cover one vehicle. It is usually the most practical option for homes with limited driveway space, narrow side access, or only one main vehicle to protect.
A typical single carport in Australia may be suitable for:
- One sedan
- One hatchback
- One SUV
- One ute
- One EV
- One motorcycle plus storage space
- A compact residential driveway
Single carports are often chosen by homeowners who want weather protection without taking up too much outdoor space.
For smaller homes, townhouses, side driveways or properties with a narrow frontage, a single carport can provide a good balance between protection, cost and available space.

Typical Single Carport Size in Australia
The exact size depends on your vehicle and driveway layout, but a common single carport size is usually around:
| Dimension | Typical Single Carport Size |
|---|---|
| Width | 3.0m to 3.6m |
| Length | 5.4m to 6.0m |
| Height | 2.4m to 3.0m |
For larger SUVs, utes or vehicles with roof racks, you may need extra height and width.
When planning a single carport, remember that the structure should not only cover the vehicle. It should also leave enough space to:
- Open car doors comfortably
- Walk around the vehicle
- Load groceries or luggage
- Access the garage or front entrance
- Use an EV charger if needed
- Avoid hitting posts or side panels
A carport that only matches the vehicle footprint may feel too tight in daily use. It is usually better to allow extra clearance where possible.
What Is a Double Carport?
A double carport is designed to cover two vehicles side by side. It is ideal for households with two cars, families with multiple drivers, or homeowners who want extra covered space for flexible use.
A double carport can be used for:
- Two daily vehicles
- One car and one ute
- One car and one trailer
- A car plus motorcycles or bicycles
- EV charging and regular parking
- Covered storage or outdoor work area
- Future vehicle needs
For many Australian families, a double carport is a long-term investment. Even if you currently own only one vehicle, the extra space may become useful later.
Ready Canopy’s double carport kits are suitable for homeowners who need wider driveway coverage and more flexible outdoor shelter.
Typical Double Carport Size in Australia
A common double carport size in Australia is usually around:
| Dimension | Typical Double Carport Size |
|---|---|
| Width | 5.5m to 6.5m |
| Length | 5.4m to 6.0m |
| Height | 2.4m to 3.0m |
For two large SUVs or utes, you may need a wider structure.
When designing a double carport, allow enough clearance between the vehicles. Many homeowners underestimate how much space is needed to open doors comfortably on both sides.
A double carport should ideally allow:
- Both vehicles to enter and exit easily
- Comfortable door opening space
- Walking access between vehicles
- Space for bins, tools or bikes if needed
- Safe clearance from boundary fences
- Enough room for driveway turning movements
If your driveway is wide enough, a double carport can make daily parking much easier.
Single vs Double Carport: Quick Comparison
| Feature | Single Carport | Double Carport |
|---|---|---|
| Vehicle capacity | 1 vehicle | 2 vehicles |
| Typical width | 3.0m–3.6m | 5.5m–6.5m |
| Typical length | 5.4m–6.0m | 5.4m–6.0m |
| Best for | Narrow driveways, one vehicle, smaller homes | Families, two cars, wider driveways |
| Cost | Lower | Higher |
| Council approval risk | Usually lower, depending on size and location | More likely to require approval |
| Future flexibility | Limited | Better |
| Installation complexity | Simpler | More planning required |
| Best user | Single-car household or compact property | Family home or multi-car household |
Which Carport Size Is Best for Your Driveway?
Before choosing a carport, start with your driveway. The size and shape of your driveway will often decide what is realistic.
Measure the following:
- Driveway width: Measure the usable width, not just the total land width. Consider garden beds, fences, walls, garage doors and existing paths.
- Driveway length: Make sure the carport can cover the full vehicle length while still allowing safe entry and exit.
- Vehicle height: SUVs, utes and vehicles with roof racks may need more clearance.
- Door opening space: Leave enough room on both sides of the vehicle to open doors comfortably.
- Turning radius: A carport should not make it harder to turn into the driveway or garage.
- Boundary setbacks: Many councils have rules about how close a carport can be to property boundaries.
- Drainage direction: Consider how rainwater will flow from the roof and away from the driveway.
If you have a narrow driveway, a single carport may be more realistic. If you have a wider driveway or multiple vehicles, a double carport may offer better long-term value.
Vehicle Type Matters: Sedan, SUV, Ute or EV?
Australian vehicles vary greatly in size. A carport suitable for a small hatchback may not be ideal for a large SUV or ute.
For Sedans and Hatchbacks
A standard single carport is usually enough for one sedan or hatchback. However, you should still allow space for door opening and walking access.
For SUVs
SUVs are wider and taller than many passenger cars. A slightly wider and higher carport may be more comfortable.
For Utes
Utes often need more length and height, especially if they have canopies, trays, toolboxes or roof racks.
For EVs
EV owners should also consider the charging position. If your charger is mounted on a wall near the driveway, make sure the carport design allows safe and easy cable access.
A double carport can also be useful if one side is used for EV charging and the other for a second vehicle.
Does a Double Carport Cost Much More Than a Single Carport?
A double carport usually costs more than a single carport because it requires more materials, a wider frame, larger roof area and potentially stronger structural design.
However, the price difference is not always double.
A double carport may provide better value per covered square metre because some design and installation costs are shared across the larger structure.
The final cost depends on:
- Carport size
- Frame material
- Roof material
- Wind rating requirements
- Freestanding or attached design
- Site preparation
- Concrete slab condition
- Council approval requirements
- Installation method
- Optional side panels or gutters
If budget is your main concern, a single carport is the lower-cost option. If long-term flexibility matters more, a double carport may be the better investment.
For a broader price breakdown, you can later connect this section to a dedicated carport cost Australia guide.
Council Approval: Does Carport Size Matter?
Yes, size can affect council approval requirements.
In Australia, carport approval rules vary by state, local council, property zoning, structure height, setback distance, roof area and whether the carport is attached to the house.
A larger double carport is more likely to require approval than a smaller single carport, especially if it is close to boundaries, near the street frontage, or affects stormwater drainage.
Before purchasing a carport kit, check:
- Local council requirements
- Boundary setback rules
- Maximum height limits
- Site coverage limits
- Stormwater management rules
- Wind rating requirements
- Whether engineering documentation is needed
- Whether the carport is attached or freestanding
Because rules vary across Australia, homeowners should always confirm with their local council or a qualified building professional.
You can also review our council approval for carports guide before planning your project.
Single Carport: Best Situations
A single carport may be the right choice if:
- You only need to cover one vehicle
- Your driveway is narrow
- You have limited front yard space
- You want a lower-cost solution
- You need a simpler installation
- You want to keep more open outdoor space
- You own a smaller vehicle
- You want to avoid overbuilding the driveway
A single carport is often the most efficient option for compact Australian homes, townhouses and side driveways.
It can provide useful protection from sun, rain, falling leaves and daily weather exposure without dominating the front of the property.
Double Carport: Best Situations
A double carport may be the better option if:
- Your household has two vehicles
- You own larger vehicles such as SUVs or utes
- You want extra covered space
- You plan to buy an EV in the future
- You need room for bikes, trailers or tools
- Your driveway is wide enough
- You want better long-term property functionality
- You prefer a balanced structure across the front of the home
For family homes, a double carport often makes more sense over time. Even if one side is not used for a second vehicle every day, the extra covered space can still be useful.
Attached vs Freestanding Carport Design
Whether you choose a single or double carport, you also need to decide between attached and freestanding designs.
Attached Carport
An attached carport connects to the house or an existing structure. It may provide convenient access between the vehicle and home entry.
It can be useful when:
- The driveway is directly beside the house
- You want covered access to the front door
- The structure can be safely fixed to the building
- The roofline and drainage can be integrated properly
Freestanding Carport
A freestanding carport is independent from the house. It is often more flexible and may be easier to position on open driveways.
It can be useful when:
- The driveway is away from the house
- You do not want to modify the existing building
- You need flexible placement
- The home structure is not suitable for attachment
For some driveways, a cantilever carport kit may also be worth considering because it can reduce the number of posts near the parking area and create a more open-sided design.
Why Aluminium Carports Are Popular in Australia
Material selection matters in Australian conditions. Carports are exposed to intense sun, rain, heat, wind, coastal air and temperature changes.
Aluminium is a popular choice because it is:
- Lightweight
- Corrosion-resistant
- Suitable for outdoor use
- Low maintenance
- Clean and modern in appearance
- Compatible with powder-coated finishes
- Easier to handle than many heavier materials
For coastal suburbs or humid regions, corrosion resistance is especially important. A powder-coated aluminium frame can provide a modern look while reducing maintenance needs.
This makes aluminium suitable for both single and double carport structures.
How to Measure Your Driveway for a Carport
Before choosing a carport kit, take accurate measurements.
Use this simple checklist:
1. Measure the available width
Measure from fence to wall, garden edge to driveway edge, or boundary to garage line. Do not assume the driveway is the same width throughout.
2. Measure the available length
Allow enough length for the vehicle and roof overhang if applicable.
3. Check vehicle size
Look up your vehicle’s length, width and height. Add extra clearance for mirrors, doors and roof accessories.
4. Check garage door clearance
If the carport is in front of a garage, make sure it does not block door movement.
5. Check slope and drainage
A sloped driveway may require additional planning for posts, footings and water runoff.
6. Mark the proposed footprint
Use chalk, tape or temporary markers to visualise the carport footprint before ordering.
7. Walk around the marked area
Pretend to park, open doors, walk around the car and access the home. This often reveals space issues early.
Taking time to measure properly can help avoid choosing a carport that feels too tight or too large.
Should You Choose a Standard Kit or Custom Size?
A standard kit may work well if your driveway is simple, flat and close to common dimensions.
However, many Australian homes have unique driveway conditions, such as:
- Narrow side access
- Sloped driveways
- Curved entry points
- Existing garden beds
- Boundary fences
- Garage door clearance issues
- Large SUVs or utes
- EV charger locations
- Council setback limitations
In these cases, a custom-sized carport may be more suitable.
Customisation can help adjust:
- Width
- Length
- Height
- Post position
- Roof style
- Frame colour
- Gutter direction
- Side coverage
- Vehicle clearance
A well-sized carport should feel like it belongs to the home rather than being forced into the space.
Common Mistakes When Choosing Carport Size
Avoid these common planning mistakes:
Choosing based only on vehicle size
Your carport should allow practical movement, not just cover the car.
Forgetting door clearance
A narrow carport may protect the car but make daily use frustrating.
Ignoring future vehicle needs
If you plan to buy a second vehicle, ute or EV, consider future requirements.
Not checking council rules early
Approval issues can delay installation or require design changes.
Underestimating height
SUVs, utes and roof racks often need more clearance than expected.
Overbuilding a small driveway
A double carport may not suit every property if it dominates the frontage or reduces access.
Ignoring drainage
Water runoff should be managed properly to avoid driveway or boundary issues.
Which Carport Is Right for You?
Choose a single carport if you want a compact, cost-effective and practical shelter for one vehicle.
Choose a double carport if you need two covered spaces, extra flexibility and better long-term usability.
As a simple rule:
- One small or medium vehicle + narrow driveway = single carport
- Two vehicles or family home + wide driveway = double carport
- Large SUV or ute = consider extra width and height
- EV charging setup = consider cable access and covered working space
- Long-term flexibility = double carport may provide better value
The best choice is the one that fits your driveway, vehicle, daily routine and future plans.

Final Thoughts
Choosing between a single and double carport is about more than the number of cars you own today. It is about driveway space, long-term convenience, council requirements, vehicle size, budget and how your home may be used in the future.
A single carport is compact, affordable and suitable for one-vehicle households or narrower driveways. A double carport provides more space, better flexibility and stronger long-term value for families and multi-car homes.
Before making a decision, measure your driveway carefully, check local council requirements and consider how your vehicle needs may change over time.
With the right planning, a carport can improve your home’s functionality, protect your vehicle and create a more practical outdoor space for everyday Australian living.
FAQ
What is the standard size of a single carport in Australia?
A common single carport size in Australia is around 3.0m to 3.6m wide and 5.4m to 6.0m long. Larger SUVs or utes may need extra width and height.
What is the standard size of a double carport in Australia?
A typical double carport is around 5.5m to 6.5m wide and 5.4m to 6.0m long. The right size depends on vehicle type, driveway space and door clearance.
Is a double carport worth it?
A double carport can be worth it if you have two vehicles, a family home, a wide driveway or future EV charging needs. It also provides more flexible covered space.
Do I need council approval for a double carport in Australia?
Council approval requirements vary by state and local council. A larger double carport is more likely to require approval, especially if it is near boundaries or affects stormwater drainage.
Can a single carport fit an SUV?
Yes, many single carports can fit an SUV, but you should check the vehicle’s height, width and mirror clearance before choosing a size.
Is aluminium good for carports in Australia?
Yes. Aluminium is lightweight, corrosion-resistant, low maintenance and suitable for Australian outdoor conditions, including coastal and humid areas.
Should I choose an attached or freestanding carport?
An attached carport may be suitable if your driveway is beside the house and you want covered access. A freestanding carport is often more flexible and does not rely on the existing building structure.
How do I know what size carport I need?
Measure your driveway width, length, vehicle size, door clearance, turning space, boundary setbacks and drainage direction. Then choose a carport that allows practical daily use, not just basic vehicle coverage.
