The cover arrives. You throw it over the car. And immediately something is wrong.
It pulls tight around the bonnet. Or it pools on the ground at the rear. Or it fits fine until a strong southerly comes through and starts flapping against your paintwork like a sanding cloth.
Wrong sizing is the most common reason car covers fail -- not the material, not the brand. The size.
This car cover size guide will walk you through how to measure your vehicle correctly, how to match those measurements to the right cover category, and which popular Australian vehicles need special attention. Whether you drive a compact hatchback or a dual-cab ute with a bull bar, here is what you need to know before you order.
Why Getting the Right Size Matters
A cover that is too small stretches over body panels, creates constant tension, and can cause fine scratches over time. It also tends to blow off in wind because there is not enough overlap at the hem to stay secure.
A cover that is too large is just as bad. Excess fabric flaps in a breeze, and that flapping acts like sandpaper against your clear coat. Loose covers also trap moisture underneath rather than letting it breathe, which leads to watermarks, surface rust, and mould -- particularly in humid coastal parts of Australia.
Universal "one size fits all" covers are the biggest culprits. They are built around a generic average and rarely account for the actual dimensions of Australian vehicles, which are increasingly large SUVs, 4WDs, and dual-cab utes with additional accessories. That is exactly where a "custom-fit car cover" earns its keep.
Step 1: How to Measure a Car for a Car Cover
Get the measurements right before you do anything else. You need three numbers: length, width, and height.
Length (the most important measurement)
Stand beside the car, not above it. Measure in a straight horizontal line from the front bumper to the rear bumper.
Do not run the tape over the bonnet, up the windscreen, across the roof, and back down the boot. That measures surface area, not vehicle length, and will give you a figure 15 to 30 percent larger than your actual cover size. It is the most common measuring mistake and leads directly to ordering a cover that is too long.
If your vehicle has a bull bar or a tow bar, add that extra length to your base measurement. These accessories are the single most common cause of fitment problems in Australia, particularly on utes and 4WDs. A standard tow bar adds roughly 80mm to 150mm. A bull bar can add 150mm to 300mm or more, depending on the style.
You can also find your vehicle's stock length in the specifications section of your owner's manual, or by searching the make and model online. Then add manually for any accessories fitted to your specific vehicle.
Width
Measure across the widest part of the vehicle. For most cars, that is from the outer edge of one side mirror to the outer edge of the other.
If your mirrors fold in, a cover can be fitted with them folded and width is less of a concern. If they do not fold, your width measurement must include them.
For reference, here are approximate average widths for common Australian vehicle categories (mirrors excluded):
- Small / compact SUV: approx. 1,800mm
- Medium SUV: approx. 1,840mm
- Ute (dual cab): approx. 1,870mm
- Large / upper SUV: approx. 1,980mm
CarsGuide average vehicle widths by category.
Height
Measure from the ground to the highest fixed point on the vehicle. If you have a roof rack, rooftop tent, or an aerial that does not retract, measure to the top of that accessory.
A cover that does not clear the full height will sit under tension at the highest point, stressing the seams, and leaving sections of your roof or rear exposed.
Step 2: Identify Your Vehicle Category
Once you have your measurements, match them to a vehicle category. This car cover size chart covers the most common body types on Australian roads:
| Vehicle Type | Typical Length (Australia) | Common Examples |
|---|---|---|
| Small Hatchback | 3,900mm to 4,300mm | Toyota Yaris, Mazda 2 |
| Medium Hatchback / Sedan | 4,300mm to 4,700mm | Toyota Corolla, Mazda 3, Hyundai i30 |
| Large Sedan / Wagon | 4,700mm to 5,000mm | Toyota Camry, Subaru Outback |
| Small / Medium SUV | 4,300mm to 4,700mm | Mazda CX-5, Hyundai Tucson |
| Large SUV / 4WD | 4,700mm to 5,200mm | Toyota Prado, Land Rover Defender |
| Ute (dual cab) | 5,200mm to 5,500mm | Toyota HiLux, Ford Ranger, Mitsubishi Triton |
| American-style Ute | 5,500mm to 6,100mm | RAM 1500, RAM 2500 |

The average car length in Australia sits at around 4,700mm across all categories. But Australians have been buying more SUVs and utes than sedans for years. If that is your vehicle, do not size for the average.
Step 3: Universal, Semi-Custom, or Custom-Fit?
Once you know your measurements, you have three types of cover to choose from. The difference matters more than most people expect.
Universal Covers
Universal covers are sized by broad category, something like "sedan up to 4.5m." They are the cheapest option, but they are built around median dimensions. If your vehicle is longer, taller, wider, or has accessories, expect a poor fit.
Loose areas flap and scratch. Tight areas stress fabric and seams. For any vehicle worth protecting, that is a bad trade-off.
Semi-Custom Covers
Semi-custom covers are designed for a specific body style and length range, for example "SUV 4.7m to 5.0m." They are a better fit than universal and more affordable than fully custom. For a stock-standard vehicle with no significant modifications, semi-custom can work reasonably well.
Custom-Fit Covers
Custom-fit covers are made to your vehicle's exact measurements. No rounding to a size bracket. No assumptions about body shape. Every centimetre is accounted for.
We Got You Covered makes every cover to order from Melbourne, with no universal sizing applied. The cover fits correctly from day one, stays secure in wind, and does not create pressure points on paintwork. Every cover ships free across Australia and is backed by a 2-year warranty.
For a classic car, a show car, or any vehicle with aftermarket modifications, custom-fit is the only sensible option.
Common Car Cover Sizing Mistakes to Avoid
These are the mistakes that lead to returns and frustration. Knowing them in advance is worth it.
Measuring over the top of the car. Running the tape over the bonnet and roof gives you surface area, not vehicle length. It produces a figure that is far too large and leads to ordering a cover that is too long.
Forgetting accessories. A bull bar, tow bar, aftermarket spoiler, or rear-mounted spare tyre all add to your effective length. Measure the full footprint as the vehicle actually sits, accessories included.
Choosing the smaller size when falling between brackets. Always go up a size. A cover with a small amount of extra length is easy to manage and puts no stress on the fabric. A cover that is slightly too short will strain constantly, is harder to put on, and is more likely to come loose in wind.
Assuming "fits sedans" covers your specific sedan. Sedans vary by 400mm to 500mm or more across different models. A cover sized for a Corolla will not properly fit a Camry. Always check your exact length, not just the body type category.
Quick Car Cover Size Guide for Popular Australian Vehicles
Here are sizing notes for the best-selling vehicles in Australia. Outdoor car covers for all of these are available made to order.
| Vehicle | Stock Length | Notes |
|---|---|---|
| Toyota HiLux (dual cab) | approx. 5,330mm | Add 150 to 300mm for bull bar |
| Ford Ranger (dual cab) | approx. 5,350mm | Add 150 to 300mm for bull bar |
| Toyota RAV4 | approx. 4,600mm | Check for roof rack height |
| Mitsubishi Triton (dual cab) | approx. 5,275mm | Add for bull bar and tow bar |
| Mazda CX-5 | approx. 4,550mm | Standard SUV sizing |
| Hyundai Tucson | approx. 4,500mm | Standard SUV sizing |
| Toyota Prado (5-door) | approx. 4,825mm | Check for snorkel and roof rack |
| Toyota Corolla (hatch) | approx. 4,375mm | Distinct length from sedan version |
| Toyota Corolla (sedan) | approx. 4,640mm | Measure if you have a spoiler |
| Kia Cerato (sedan) | approx. 4,640mm | Standard medium sedan sizing |
| Subaru Outback | approx. 4,870mm | Wagon; include roof rails in height |
These are manufacturer-listed stock lengths. If your vehicle has any aftermarket additions, measure it directly rather than relying on these figures.
FAQ
Q: How do I know if a car cover will fit my ute's bull bar?
Measure from the very front of the bull bar to the very rear of the vehicle, including any tow bar or hitch receiver. That total figure is your effective vehicle length. Choose a cover that meets or exceeds it. A custom-fit cover can be made to your exact total length, which is the safest approach for any heavily accessorised ute or 4WD.
Q: Should I size up if my measurement falls between two cover sizes?
Always go up a size. A cover with a little extra length puts no stress on the fabric, is easier to fit, and will not leave any part of the vehicle exposed. A cover that is even slightly too small will pull at the edges constantly and is more likely to come loose in wind.
Q: Do I need a different cover for indoor and outdoor use?
Yes. Indoor covers should be soft, breathable, and dust-resistant. The material needs to let moisture escape while protecting paint from dust and accidental contact. Outdoor covers need to handle UV radiation, rain, wind, and in parts of Australia, hail. The materials, construction, and fastening systems are quite different between the two. Using an indoor cover outdoors regularly will shorten its life significantly.
Q: Can I use a universal cover on my SUV or 4WD?
Technically, but expect a compromised fit. Universal covers are built around average sedan dimensions. On a large SUV or 4WD, they typically run short in length, tight across the roofline, and loose at the sides. That loose fabric flaps in wind and can scratch paint. A custom outdoor car cover will protect your vehicle far more effectively.
Q: Does height matter if I just have a small antenna?
A standard rubber aerial is usually flexible enough that a cover sits over it without problem. A fixed extruded aerial is a different situation. We Got You Covered has specific guidance on handling permanent extruded aerials -- worth reading before ordering if your vehicle has one.
Get a Cover Made for Your Exact Vehicle
