Caravan Annexe Matting Sizes & Dimensions Guide Australia 2026

Getting the right caravan annexe matting sizes and dimensions makes a genuine difference to how comfortable and usable your campsite feels.  Standard caravan awnings in Australia measure between 2.4m and 2.5m wide arm to arm, and your mat needs to match that width and complement the full run length of your annexe to give you a clean, functional outdoor living space.

Payload is another dimension that often gets overlooked when buying matting: annexe matting counts toward your caravan's available payload (ATM minus Tare), and across the size range available, weights vary from around 4.5kg for a compact 3m mat up to approximately 10.5kg for a full 7m piece of 600gsm PVC foam. 

Before you buy, measure your awning from arm to arm, know your payload budget and understand suits your typical camping surfaces.

Caravan annexe matting in 2026 comes in 5 common lengths:

1. 3m x 2.5m (compact caravans and camper trailers)
2. 4m x 2.5m (small caravans, approx 4.6m to 5.5m body length)
3. 5m x 2.5m (medium caravans, approx 5.5m to 6.1m body length)
4. 6m x 2.5m (medium-large caravans, approx 6.4m to 7m body length)
5. 7m x 2.5m (large caravans, over 7m body length)

There are 3 common caravan annexe matting styles:

1. PVC foam (foamed PVC)
2. Woven polypropylene (synthetic mesh)
3. Multi-layer knit

3m Caravan Annexe Matting Sizes & Dimensions

A 3m annexe mat is the practical choice for compact pop-top caravans, lighter camper trailers, and weekend getaway setups where the annexe is used as a shaded entry rather than a full outdoor living room. 

It suits caravans with a body length up to around 4.3m and works well for couples on regional Victorian roads or short coastal getaways where setup and pack-down speed matters. It is also worth considering if your payload is already tight, since the shorter length keeps the weight impact on your ATM to a minimum.

• Length: 3m
• Width: 2.5m (standard PVC foam); 2.4m (multi-layer knit styles)
• Area: approx 7.5 sq m
• Weight (600gsm PVC foam): approx 4.5kg
• Typical colours: grey, green, blue
• Includes: carry bag

4m Caravan Annexe Matting Sizes & Dimensions

The 4m annexe mat covers most small to medium caravans with a body length between approximately 4.6m and 5.5m. It is a versatile, widely stocked size that works well for a couple on a two or three week trip, giving enough floor space for camp chairs, a table, and a bit of room to move without feeling cramped. It is also a popular choice for hybrid camper trailers with full roll-out annexes.

• Length: 4m
• Width: 2.5m (standard PVC foam); 2.4m (CGear 4.3m x 2.4m multi-layer knit)
• Area: 10 sq m
• Weight (600gsm PVC foam): approx 6kg
• Weight (CGear 4.3m x 2.4m multi-layer knit): 4.8kg
• Typical colours: grey, green, blue
• Includes: carry bag

5m Caravan Annexe Matting Sizes & Dimensions

A 5m mat suits medium caravans with body lengths between roughly 5.5m and 6.1m. This is where many family setups land, and the extra metre over a 4m mat makes a noticeable difference when children are using the annexe as a play area or when you are staying put for a week at a caravan park.

For Grey Nomads doing longer stints on the Big Lap, the 5m size gives enough covered floor area to feel like a proper outdoor room without pushing the payload budget into uncomfortable territory. 

• Length: 5m
• Width: 2.5m (standard PVC foam); 2.45m (Supex SureMat); 2.4m (CGear 5.2m x 2.4m)
• Area: approx 12.5 sq m
• Weight (600gsm PVC foam): approx 7.5kg
• Weight (CGear 5.2m x 2.4m multi-layer knit): 5.8kg
• Packed carry bag (Weisshorn 5m example): approx 54 x 45 x 18cm
• Typical colours: grey, green
• Includes: carry bag

6m Caravan Annexe Matting Sizes & Dimensions

The 6m mat is one of the most popular sizes in the Australian market. It suits caravans with body lengths of roughly 6.4m to 7m, covering the full annexe footprint without excess mat folding beyond the awning arms. It is the default choice for families staying a week or longer, and for Grey Nomads with a full annexe setup.

Payload note: at roughly 9kg for a 600gsm PVC foam mat, it is worth factoring into your ATM budget. Choosing a multi-layer knit at this size saves approximately 2kg with no change in coverage.

• Length: 6m
• Width: 2.5m (standard PVC foam); 2.4m (CGear 6m x 2.4m multi-layer knit)
• Area: 15 sq m
• Weight (600gsm PVC foam): approx 9kg
• Weight (CGear 6m x 2.4m multi-layer knit): 7kg
• Packed carry bag (Weisshorn 6m example): approx 54 x 45 x 21cm
• Typical colours: grey, green
• Includes: carry bag

7m Caravan Annexe Matting Sizes & Dimensions

A 7m mat is the largest standard size in the Australian market, built for long caravans with a body length over 7m. It is especially popular with Grey Nomads in larger tandem-axle vans who set up for extended periods at places like a Red Centre campground or a tropical north Queensland caravan park.

The trade-off is weight: at approximately 10.5kg for a 600gsm PVC foam mat, this is the heaviest option in the range and the most significant for payload calculations. If your payload is tight, switching to a lighter material at this size can save 2 to 3kg with no reduction in coverage.

• Length: 7m
• Width: 2.5m (standard PVC foam)
• Area: approx 17.5 sq m
• Weight (600gsm PVC foam): approx 10.5kg
• Typical colours: grey, green
• Includes: carry bag

Additional Caravan Annexe Matting Considerations

1. Measure your awning arm to arm, not your van body length: The caravan body length listed by a manufacturer is not the same as your awning run length. Most awnings run approximately 1m shorter than the van body due to the front tunnel boot position. Use a tape measure from awning arm to awning arm before choosing your mat length. A mat that is too long will fold at the edges and become a tripping hazard; one that is too short will leave an uncovered gap at either end of your annexe.
2. Width compatibility with your awning: Most Australian caravan awnings sit between 2.4m and 2.5m wide. PVC foam mats are typically 2.5m wide, while multi-layer knit options such as CGear run at 2.4m. Matching the mat width to your awning spread keeps the mat neatly inside the footprint, prevents exposed edges lifting in the wind, and reduces the chance of a trip hazard in the dark.
3. Payload and ATM impact: Annexe matting is payload, not Tare. On a van with 600kg of payload already loaded with water, food, and camping gear, a 7m foam mat at 10.5kg is a meaningful number. A lighter material or shorter size can help keep you within your towing limits.
4. Ground surface compatibility: PVC foam performs best on grassed or soft dirt surfaces. On rough gravel, concrete, or abrasive outback tracks it wears faster and may not lie flat. Woven polypropylene and multi-layer knit handle a wider range of surfaces, including hard-standing powered sites.
5. Caravan park approval: Most Australian caravan parks require matting that is breathable and allows the ground beneath to stay healthy. PVC foam, woven polypropylene, and multi-layer knit mats all meet standard Australian caravan park requirements. Solid-backed rubber or impermeable mats are generally not accepted. If you are heading to a specific park for a long stay, a quick call to confirm their ground cover policy is worth the effort.

Common Caravan Annexe Matting Materials

While aluminium framing dominates the structural side of the caravan industry, annexe matting uses fabric and polymer-based materials. Your choice of material affects total weight, surface compatibility, pack size, and longevity. Here are the three main options in the Australian market.

PVC Foam (Foamed PVC)

PVC foam is the most common annexe matting material across Australian caravan retailers. It is manufactured from foamed PVC, giving it a soft, slightly rubbery feel underfoot. It comes in two weight grades: a standard 450gsm and a heavy-duty 600gsm.

Based on published Supex specifications, the 600gsm grade weighs approximately 1.5kg per linear metre at the standard 2.5m width. This means mat size directly determines total weight, and you can calculate your specific mat weight by multiplying the length in metres by 1.5.

Pros:

• Soft and comfortable underfoot, including barefoot use on warm days
• Breathable open-cell structure allows water, sand, and fine dirt to pass through
• UV treated and non-slip surface for safe everyday use
• Widely available at Australian caravan retailers and generally the most affordable option
• Approved for use in the majority of Australian caravan parks

Cons:

• Heavier than woven or multi-layer knit alternatives at equivalent lengths
• Wears faster on rough concrete, gravel, or abrasive outback dirt
• Can retain moisture underneath in prolonged wet conditions if not dried between uses

Woven Polypropylene (Synthetic Mesh)

Woven polypropylene matting is made from tightly woven synthetic fibres, often with a two-tone pattern and a polyester or similar coating that adds mildew resistance. This style is used in ranges such as the Camec outdoor flooring line and is a durable choice for caravanners who use their van across a variety of surfaces and conditions.

The open-weave structure promotes air circulation underneath, which helps preserve grass at caravan park sites.

Pros:

• Rot-proof and UV stabilised for extended durability in Australian sun and rain
• Mildew and mould resistant coating suits humid coastal conditions
• Pegging eyelets prevent the mat from lifting or becoming a trip hazard in wind
• Performs well across grassed, compacted dirt, and some hard-standing surfaces

Cons:

• Less cushioned underfoot compared to PVC foam
• Fine grit and sand can sit in the weave and requires shaking out after dusty campsites

Multi-layer Knit

Multi-layer knit matting, best known through CGear's internationally patented technology, uses a layered knit construction that allows sand and fine particles to fall through and not resurface. It is the lightest option available: a CGear 6m x 2.4m multi-layer knit mat weighs 7kg, compared to approximately 9kg for a comparable 600gsm PVC foam mat. T

hat 2kg saving is particularly relevant for Grey Nomads heading to fine-dust outback tracks or sandy coastal camping spots in Western Australia and tropical north Queensland.

Pros:

• Lightest weight option at equivalent sizes, saving 2 to 3kg over foam at the 6m length
• Sand and fine dust pass through the mat and do not resurface underfoot
• Reinforced edges and D-ring pegging points for a secure, low-profile setup
• Highly durable and tear-resistant knit construction

Cons:

• Higher price point than PVC foam or woven polypropylene
• Slightly narrower at 2.4m, compared to the 2.5m standard width for foam mats

For most caravanners doing regular caravan park stays on grassed sites, 600gsm PVC foam is the practical default and the best value entry point. If you regularly camp in sandy, dusty, or outback conditions, multi-layer knit is worth the investment for the sand-free benefit and the weight saving.

Woven polypropylene sits in the middle ground, offering better durability across mixed surfaces than foam without the premium price of knit technology.

Top 6 Tips for How to Choose Caravan Annexe Matting Size and Style

Getting the right annexe mat is straightforward once you know what to measure and what to prioritise.

1. Measure your awning arm to arm, not your van length
   The body length your manufacturer quotes is not the same as your awning run. Most awnings sit approximately 1m shorter than the van body due to the front tunnel boot. Measure arm to arm with a tape measure before you buy.
2. Factor matting weight into your payload
   Annexe matting is payload, not Tare. A 7m PVC foam mat at 10.5kg is a meaningful chunk of a 600kg payload allowance. At the 6m size, switching from foam (9kg) to multi-layer knit (7kg) frees up 2kg with no change in coverage.
3. Match the material to your camping surface
   PVC foam suits grassed caravan parks and soft dirt. If you camp on rough gravel, hard-standing powered sites, or abrasive outback tracks regularly, woven polypropylene or multi-layer knit will hold up better. Foam degrades faster on abrasive surfaces.
4. Stick to 2.4m or 2.5m width
   Most Australian caravan awnings spread between 2.4m and 2.5m arm to arm. Matting at this width sits neatly within the footprint and avoids exposed edges that lift in the wind or become a trip hazard after dark.
5. Consider pack size and storage space
   A 6m PVC foam mat packs to roughly 54 x 45 x 21cm in its carry bag, which fits most tunnel boots comfortably. At 7m, the roll is noticeably bulkier. Multi-layer knit mats roll to a smaller diameter at the same length due to their thinner construction.
6. Check your caravan park's ground cover policy
   Most Australian caravan parks require breathable, grass-friendly matting. PVC foam, woven polypropylene, and multi-layer knit mats all meet the standard requirements. For eco-focused parks or national park campgrounds, a quick call ahead of arrival is worth it.

Getting the right caravan annexe matting size comes down to three things: measuring your awning accurately, knowing your payload budget, and matching the material to your typical camping ground.
