The Most Common Carport Sizes in Australia

If you’re in the market for a carport, you may like to understand the most common carport sizes in Australia; the common sizes used across Australia and why those numbers matter. Too often, people grab whatever looks cheapest or “standard” and end up with a carport that’s cramped, too low, 

Here’s the no-nonsense breakdown on carport sizes, what works, what to question, and practical tips to get it right the first time.

Common Carport Dimensions: Bigger Isn’t Always Better, But Too Small Is Worse

Single Skillion Carport, (Flat roof Carport): Usually 3m x 6m

The typical single carport is 3 metres wide by 6 metres long. Some suppliers offer a minimum size of 3.0m x 5.4m, but don’t be fooled by “minimum” here—less space means squeezing your vehicle in and having no room to breathe or store stuff.

The standard 3 x 6 size gives you enough space to:

1. Open your car doors comfortably.
2. Store a few items on the side or at the back.
3. Avoid backing out blind or scraping paint on posts.
4. Usually has a clearance height of 2.4m or 2.1m. 2.4m clearance is extremely popular.

Why is this the most common size? Simply stated, a few suppliers have one or two ‘standard’ sizes that they offer ‘off-the-shelf.’ Plans, certification, and engineering drawings are all sitting ready for use, so the off-the-shelf is usually cheaper. That’s why more are sold, not necessarily because it is a generous size that suit most customers!

Double Carport: Typically, 6m x 6m

For two vehicles side-by-side, 6 metres by 6 metres is the go-to “standard”. It allows ample room for:

1. Both cars to park without overlapping edges
2. Doors to open wide enough for easy in/out
3. Some additional storage or workspace, if needed
4. Clearance height usually around 2.4m.

You might find tighter options like 5.5m x 5.5m on the market, but don’t kid yourself: these leave less wiggle room and increase the risk of dings, scratches, and general frustration.

Why is this the most common ‘double carport’ size? Again, as above, a few suppliers have one or two ‘standard’ sizes that they offer ‘off-the-shelf.’ Plans, certification, and engineering drawings are all sitting ready for use, so the off-the-shelf is usually cheaper. That’s why more are sold, not necessarily because it is the best size that suit all customers!

Triple Carport: Around 9m x 6m Carport

If you need space for three vehicles, expect about 9 metres wide by 6 metres long. We are not aware of any Australian supplier who has a 9x6 off-the shelf, so it will be a custom-made job. If it is going to be custom-made, get your measuring tape out! Measure the area to be covered and buy a carport to cover the whole area. If you find it’s 10.3 x 5.8m that’s good. Get your carport designed to fit the space. Also, you are not restricted to a 2.4m clearance. It can be made to any clearance height you choose.

Cheaper off-the-shelf carports are usually relatively easy to install DIY. The custom-made range through Car Covers and Shelter comes with state-of-the-art engineering drawings. Every joint is clearly illustrated with a YouTube video link to help make installation easy.

Height: Don’t Overlook It

All off-the-shelf, less expensive carports are designed to a maximum 2.4 metres clearance They are 

A low carport can guzzle your head clearance and damage rooftop accessories. Better safe than sorry here.

Important Considerations: What the Industry Won’t Always Tell You

Your Vehicle Size Is King

These standard sizes cannot be modified in any way, what you see is what you get. Changing them in any way will be the certification is no longer valid. Your vehicles might be larger—or you may want comfortable space around them. Looking at the design of your carport, rule of thumb would be:-

1. Allow at least 300mm extra width per side of your vehicle for easy door opening and movement.
2. Add 600 to 900mm extra length so you’re not bumper-to-post every time you park.

Council Rules Are Not Optional, The Most Common Carport Sizes in Australia

Before you order or build, check with your local council’s regulations. They often have strict limits on:

1. Maximum carport size and height
2. Setback from property boundaries
3. Materials and design standards

Ignoring these can lead to fines or forced removal. It’s bureaucratic, but unavoidable.

Think Ahead: Your Future Self Will Thank You

Even if you’ve only got one small car now, many homeowners choose slightly larger carport dimensions for:

1. Buying a bigger or second vehicle down the track
2. Extra storage for bikes, tools, or garden equipment
3. Improving property resale value with a more versatile carport

 

Quick Practical Checklist Before You Buy a Carport

1. Measure your vehicle(s) precisely (length & width)
2. Add at least 300mm clearance per side and 600-900mm lengthwise.
3. Better still, if you have more space, design a carport to cover the whole area.
4. Choose width/length based on single, double, or triple sizing standards.
5. Pick eave height suitable for your tallest vehicle or gear on top.
6. Consult your local council for size, height, and setback rules.
7. Consider future needs—not just your current car(s)
8. Don’t compromise on clearance to “save” a few bucks—space is safety.

 

The Most Common Carport Sizes in Australia, Summary

The most common carport sizes in Australia—3m x 6m for singles and 6m x 6m for doubles—are popular because that’s what is offered to you in cheaper carport kits! They do strike a balance between tight and spacious, affordable, and functional. But don’t assume these dimensions will suit every situation. Measure your installation area and vehicles, think about access, check local rules, and plan for what you’ll need next year, not just today.

Don’t fall for marketing pitches selling you “compact” or “space-saving” less expensive carports that end up as frustrating tight squeezes. The cheapest isn’t always best—sometimes spending a little more on space is the smartest investment you make.
