Caravan Awnings Sizes & Dimension 2026 | Charts & Advice

Getting your caravan awning sizes and dimensions right can make or break the comfort of a campsite setup, whether you're doing laps around the Victorian High Country or settling in for a few weeks at a coastal caravan park in Far North Queensland.

Before you commit to anything, take a proper measurement of your caravan's side wall, check what projection your typical campsites can accommodate, and have a look at how much payload capacity you've got left after the van is kitted out.

Caravan Awnings in 2026 Come in 4 Common Types:

1. Roll-out awnings
2. Box and cassette awnings
3. 4WD and freestanding awnings
4. Full-room caravan annexes

There are 2 common caravan awning mounting configurations:

1. Wall-mount (side-mount)-by far the most common for caravans and motorhomes
2. Roof-mount: used on campervans and some off-road trailers

Below is a guide on the most common caravan awning sizes, dimensions, configurations, and materials.

Roll-Out Caravan Awning Sizes & Dimensions

Roll-out awnings are the most popular type fitted to Australian caravans, and for good reason. They're simple to operate, proven in the field, and widely supported with replacement parts and accessories. Roll-out awnings are sold in foot increments in Australia, though the metric equivalents are what matter for site planning.

Common caravan sizes range from 3.0m (10ft) through to 6.4m (21ft), with 3.7m to 6.1m being the sweet spot for most full-size caravans.

• Available lengths: 3.0m (10ft) to 6.4m (21ft)
• Most common sizes for standard caravans: 3.7m (12ft) to 6.1m (20ft)
• Standard projection (extension from caravan wall): 2.4m to 2.5m
• Roller tube diameter: approximately 102mm (varies by brand)
• Fabric weight (vinyl): 450 to 500g/m² (laminated 3-layer construction)
• Typical weight: 18kg to 35kg depending on size and whether hardware is included.
• Shade coverage example: a 4.9m (16ft) awning at 2.5m projection covers approximately 12.25m²

Box and Cassette Caravan Awning Sizes & Dimensions

Box and cassette awnings take things up a notch in terms of protection and presentation. The entire awning, including the fabric, arms, and mechanism, retracts into a hard aluminium cassette that mounts flush against the caravan wall.

When stowed, the unit adds roughly 100mm to your van's profile, which is great news for tight campsite access and towing clearance.

The Fiamma F45 S is probably the most recognised box awning on Australian roads, and it's a popular upgrade for caravanners who want something a bit more polished than a standard roll-out. Box awnings suit longer-stay setups where you want reliable operation and protection for the fabric, particularly in coastal and tropical conditions.

• Available lengths (Fiamma F45 S): 1.9m, 2.3m, 2.6m, 3.0m, 3.5m, 4.0m, 4.5m
• Standard projection: 2.5m (consistent across all lengths)
• Cassette profile: compact aluminium housing that sits flush against the caravan wall when closed
• Shade surface area: approximately 8.3m² (3.5m model, calculated as 3.31m canopy x 2.5m projection)
• Weight: approximately 25kg (3.5m model), approximately 27kg (4.0m model)
• Canopy dimensions (3.5m model): total length 348cm, canopy length 331cm, projection 250cm
• Canopy dimensions (4.0m model): total length 398cm, canopy length 381cm, projection 250cm
• Fabric: UV-resistant vinyl canopy, washable, polar white or deep black cassette options

4WD and Freestanding Awning Sizes & Dimensions

These aren't just for serious off-roaders. A growing number of Grey Nomads and weekend explorers are opting for a freestanding or vehicle-mounted side awning as a versatile alternative to a fixed wall-mount setup.

They suit camper trailers, rooftop tent rigs, and dual-cab 4WDs equally well, and many can be positioned independently of the vehicle once set up. If you're doing a Big Lap with a mix of campgrounds and bush camping, a 270-degree wrap-around awning can transform the whole side and front of your rig into a shaded outdoor area without needing to attach walls or annex panels.

• Standard side awning (180°): typically 2.0m x 2.5m (5.0m² coverage)
• 270-degree freestanding awning: shade coverage varies by brand, typically 9m² to 11.5m² (e.g., Darche Eclipse 270 provides 11.5m²)
• Weight (270° model): approximately 23 to 28kg depending on brand and frame material
• Fabric weight: typically 280 to 320g/m² ripstop polyester or polycotton canvas with UPF 50+ and 1500 to 3000mm waterproof rating
• Pack size: varies by model; most mount to a roof rack cross-bar and stow in a carry bag or bracket system against the vehicle
• Projection: 2.0m to 2.5m depending on model and mounting position

Full-Room Caravan Annex Sizes & Dimensions

A full-room caravan annex turns your awning into a proper enclosed living space. These fabric rooms zip or clip onto the lead bar of your roll-out awning and are popular with caravanners who stay in one spot for days or weeks at a time.

Annexes come in heavy-duty canvas or poly-cotton blends designed for the extremes of the Australian climate. Sizing is dictated by your awning, so the annex width must match your awning length precisely.

• Annex width: matches awning length (3.0m to 6.4m)
• Depth: typically 2.5m, matching standard awning projection
• Wall height: typically 1.8m to 2.0m
• Privacy screen dimensions (separate roll-out accessory): 2.8m, 3.1m, 3.4m, 3.7m, 4.0m, 4.3m, 4.6m, and 4.9m wide x 1.8m tall (choose to match your awning length)
• Full floor area example: a 3.7m awning with 2.5m projection creates a 9.25m² annex footprint
• Full floor area example: a 6.1m (20ft) awning creates a 15.25m² annex footprint
• Fabric: typically heavy canvas or poly-cotton blend, 280 to 320gsm

Additional Caravan Awning Considerations

1. Payload impact (ATM and Tare Mass):

Any awning added after delivery is not included in your caravan's Tare Mass, which means it directly reduces your available payload. A roll-out awning with hardware typically adds 20 to 35kg.

If your caravan's ATM is 2,500kg and Tare Mass is already 1,900kg, your payload budget is just 600kg and every accessory, from the awning to water and gear, comes out of that figure. Always check your compliance plate and recalculate payload after adding accessories.

2. Mounting height requirements:

Standard awning arm hardware requires a minimum caravan wall height of approximately 1,620mm at the mounting point. If you have a tall caravan or a high wall profile, look at tall hardware variants.

Pop-top caravans and some compact vans may suit ultra-short hardware instead. Always measure the wall height before ordering a hardware kit.

3. Projection versus campsite width:

A 2.4m to 2.5m projection is standard in Australia and suits most caravan park sites. However, busy coastal parks, some national park sites, and popular free-camping spots can have tight pitches where a full 2.5m extension may push beyond your site boundary. If you camp in those locations regularly, check site dimensions in advance and be prepared to partially extend.

Fabric and brand compatibility:

Roll-out awning barrels and replacement fabrics are not interchangeable between all brands. If you're buying replacement vinyl or planning to upgrade the fabric, confirm compatibility with the barrel diameter and end cap design before ordering.

Privacy screen sizing:

Awning privacy screens and end drops attach to the lead bar of your roll-out or box awning. Standard screen heights are 1.8m, designed to suit most caravan wall heights. Screen width should match your awning's lead bar length: commonly available in increments from 2.8m to 4.9m wide. Measure the lead bar length of your awning, not the full caravan, to size a privacy screen correctly.

Top 6 Tips for Choosing Your Caravan Awning Size and Style

1. Measure your caravan's side wall before anything else

The maximum awning length is dictated by the mountable wall space on your caravan, typically measured from the front mounting bracket position to the rear. Anything longer risks overhanging the bumper or awning rail ends. Get the tape out and measure in metres before looking at product sizes.

2. Check your payload budget before selecting a size

Awnings are heavier than most people expect. A roll-out awning with hardware can add 20 to 35kg to your rig. On a lightweight off-road camper trailer with an ATM of 1,200kg and Tare Mass already at 900kg, that leaves 300kg for everything including water, food, gear, and passengers. Know your payload limits and weigh up the awning as part of that calculation, not as an afterthought.

3. Match the awning type to your trip style

Grey Nomads doing long stays at caravan parks will get the most out of a full-length roll-out with a privacy screen or annex walls. Weekend bush campers and 4WD tourers are often better served by a compact box awning or a freestanding 270-degree unit that can be set up quickly without needing level ground or fixed arms.

4. Know the typical pitch size at your usual campsites

A 2.5m projection is standard, but coastal caravan parks, national park sites, and popular free-camping spots can have tight or irregular pitches. If you regularly park in places where space is limited, a 2.2m to 2.4m projection awning may serve you better than the full 2.5m. Some sites will simply not allow full projection at all.

5. Think about stowed pack size and towing width

Box awnings add approximately 100mm to your caravan's towing profile when closed. Roll-out awnings with arms folded back can add 250mm to 400mm depending on the arm design and bracket position. Australia's maximum vehicle width including accessories is 2.5m. Know your caravan's base width and make sure the stowed awning won't push you over that limit.

6. Size your privacy screen to the awning, not the caravan

A common mistake is selecting a privacy screen the same length as the van. The screen needs to match your awning's lead bar length, which is typically the awning length you purchased. Pick the size that matches your awning, and you'll get a proper fit to the lead bar track.

Whether you're planning a slow loop through the Kimberley, a season on the Murray, or a weekend down the Great Ocean Road, choosing the right caravan awning size starts with knowing your measurements and your payload limits.
