Caravan Cover Sizes & Dimensions 2026

Getting the right caravan cover sizes and dimensions is one of those details that separates a cover that works from one that flaps around in the wind and does more harm than good. 

Too short and the cover will not reach; too loose and it will rub against your paintwork. Before you buy, grab a tape measure and get the correct body length of your caravan.

Caravan covers in 2026 come in three common types:

1. Full-Height Caravan Covers
2. Pop-Top Caravan Covers
3. Camper Trailer Covers

Within each type, covers are available to suit these caravan body length ranges:

1. 12-14ft (approx. 3.66-4.27m)
2. 14-16ft (approx. 4.27-4.88m)
3. 16-18ft (approx. 4.88-5.49m)
4. 18-20ft (approx. 5.49-6.10m)
5. 20-22ft (approx. 6.10-6.71m)
6. 22-24ft (approx. 6.71-7.32m)
7. 24-26ft (approx. 7.32-7.92m)

Full-Height Caravan Cover Sizes & Dimensions

Full-height covers are designed for standard caravans with a fixed roof and full interior standing room. They are the most common cover type sold in Australia and suit everything from a compact couples van on a regional weekend trip to a large touring rig doing extended free camping.

Caravan covers in this category are dimensioned to accommodate Australia's standard caravan width, which is capped at 2.5 metres under Australian Design Rules, with most quality covers extending to around 2.64m in fitted width to allow for smooth fitting and removal. 

Heights vary by van, with standard Australian caravans typically sitting between 2.7 and 3.2 metres tall when measured to the roofline.

Compact Full-Height Caravan Covers (14-18ft / 4.28-5.49m)

These covers suit smaller touring vans, entry-level family rigs, and hard-floor off-road caravans used for weekend getaways and short touring trips. Based on verified ADCO Olefin HD and Aussie Traveller specifications from Australian retailers:

• 14-16ft: Fits caravan body lengths from 4.28m to 4.89m. Cover fitted width: 2.64-2.65m. Side drop (height): approx. 2.20-2.36m. Approximate weight: 11.9kg.
• 16-18ft: Fits caravan body lengths from 4.90m to 5.49m. Cover fitted width: 2.64-2.65m. Side drop: approx. 2.20-2.36m. Approximate weight: 12.7kg.

Mid-Size Full-Height Caravan Covers (18-22ft / 5.49-6.73m)

This is the most popular size range for Australian touring caravans. Grey Nomads heading off on the Big Lap and couples doing extended trips along the east coast will most commonly find their van falls into this bracket.

These vans typically have full ensuites, slide-out annexes, and dedicated sleeping areas. ADCO Olefin HD cover dimensions for this range, as listed by Australian retailers:

• 18-20ft: Fits caravan body lengths from 5.51m to 6.12m. Cover fitted width: 2.64m. Side drop: approx. 2.36m.
• 20-22ft: Fits caravan body lengths from 6.12m to 6.73m. Cover fitted width: 2.64m. Side drop: approx. 2.36m.

Large Full-Height Caravan Covers (22-26ft / 6.73-7.92m)

Larger vans are increasingly common among long-term travellers, families, and caravanners who need separate sleeping rooms, dual slide-outs, or extended storage bays.

Covers in this range need to be sized generously to ensure an even wrap without stretching at the corners. Verified ADCO dimensions for this range:

• 22-24ft: Fits caravan body lengths from 6.73m to 7.34m. Cover fitted width: 2.64m. Side drop: approx. 2.36m.
• 24-26ft: Fits caravan body lengths from 7.34m to 7.92m. Cover fitted width: 2.64m. Side drop: approx. 2.36m.

Pop-Top Caravan Cover Sizes & Dimensions

Pop-top caravans have a collapsible roof section that sits low when the van is being towed and raised to full height once parked. This lower roof profile makes a dedicated pop-top cover essential.

A full-height caravan cover will be baggy and too tall across the roof area of a pop-top, creating loose fabric pockets that catch the wind and pool water. Pop-top covers are built with a shallower side drop, typically around 1.77-1.80m, compared to the 2.20-2.36m drop of a full-height cover.

They are popular with weekend travellers, retirees at caravan parks, and couples who want reliable UV and weather protection between shorter trips along the Victorian coast or inland.

Small Pop-Top Covers (12-16ft / 3.66-4.88m)

These covers are well suited to compact pop-top vans used for regional weekends, couples' getaways, and short touring trips. Verified set-up dimensions from the Aussie Traveller pop-top cover range, as listed by Australian retailers:

• 12-14ft: Fits caravan body lengths from approx. 3.66m to 4.27m. Set-up dimensions (L x W x H): 4.30m x 2.65m x 1.77m. Weight: 9.4kg. Packed size: approx. 53 x 37 x 37cm.
• 14-16ft: Fits caravan body lengths from approx. 4.27m to 4.88m. Set-up dimensions (L x W x H): 4.90m x 2.65m x 1.77m. Weight: 10.0kg. Packed size: approx. 53 x 37 x 37cm.

Mid-Size Pop-Top Covers (16-20ft / 4.88-6.10m)

The most common range for popular Australian pop-top models. Many couples doing coastal caravan park stays or inland touring around New South Wales and Victoria will find their van fits here. Verified dimensions from the Aussie Traveller pop-top cover range:

• 16-18ft: Fits caravan body lengths from approx. 4.88m to 5.49m. Set-up dimensions (L x W x H): 5.50m x 2.65m x 1.77m. Weight: 10.9kg.
• 18-20ft: Fits caravan body lengths from approx. 5.49m to 6.10m. Set-up dimensions (L x W x H): 6.10m x 2.65m x 1.77m. Weight: 11.4kg.

As a comparison, the Premier Platinum pop-top cover in the 16-18ft range is sized at 4.80-5.40m body length, with a roof width of 2.4m and a side drop of 1.8m. Slightly different proportions between brands are common, which is why measuring your specific caravan and comparing those measurements against a cover's stated dimensions is always worthwhile before you buy.

Camper Trailer Cover Sizes & Dimensions

Camper trailer covers are designed for folded soft-floor and hard-floor camper trailers, not for raised or erected setups. When folded down for transport and storage, camper trailers sit very low, typically between 1.0m and 1.4m in overall height, which means a standard caravan cover will not give a proper fit and will create excessive loose fabric that flaps and abrades.

A well-fitted camper trailer cover sits snugly over the entire folded trailer, including the storage box and gas bottle holder, protecting from UV, road dust, and moisture during storage. They are ideal for families who do regular free camping or off-road trips and want to protect their trailer during the off-season or between school holiday runs into the outback or high country.

Cover size range:

Camper trailer covers typically range from 10-16ft in body length (approx. 3.05m to 4.88m), designed to suit the most common Australian folding camper trailer formats.

Cover width:

Approx. 2.4-2.65m, to accommodate standard Australian camper trailer tub widths.

Side drop:

Significantly lower than pop-top and full-height covers to match the folded trailer profile. Check the manufacturer's stated side drop against your own trailer's folded height measurement.

Packed storage size:

When folded, most camper trailer covers pack into a carry bag around 50-55cm x 35-40cm in size, making them easy to store inside the trailer itself when travelling.

Additional Caravan Cover Considerations

1. Measure body length only, not overall length.

Caravan body length is measured from the front of the body panel to the rear panel, excluding the drawbar, A-frame, gas cylinder holders, stone guard, spare wheel mount, and any bike racks or jerry cans at the rear. Using your overall rig length instead of body length will result in an oversized cover that does not fit snugly around the van's body contours.

2. Always add 15-20cm before selecting a size.

Once you have your body length measurement, add 15-20cm and then choose the closest cover size above that figure. This buffer allows for easier fitting and removal and ensures the cover is not stretched tightly at the rear corners, which is where tearing most commonly occurs.

3. Consider cover weight against your payload budget.

Most caravan covers weigh between 9kg and 13kg depending on size and material. While small relative to a full touring load, this is worth keeping in mind if your rig is already close to its ATM (Aggregate Trailer Mass). Payload capacity equals ATM minus Tare Mass, and a heavier cover stored inside the van while travelling does count toward that figure.

4. Breathability is essential in Australian conditions.

A non-breathable cover traps moisture against the caravan's exterior, which causes mould, rust, and paint damage over time. This is a particular concern in tropical north Queensland, along the humid east coast, and in areas with significant overnight temperature variation. Look for covers with a breathable side panel or mesh venting system.

5. Check the securing system suits your storage situation.

A cover that fits correctly will not billow in the wind, but the securing system still matters. Quality covers use a combination of elasticated hems, buckle straps, and undercarriage skirt clips. If your van is stored in an exposed location or somewhere prone to strong winds, a cover with multiple clip-down points and a robust strap system is a safer choice than one held only by a drawstring hem.

Top 6 Tips for How to Choose the Right Caravan Cover Size and Style

These are the practical things worth thinking through before you commit to a cover.

1. Measure from body panel to body panel, not from hitch to bumper.

Cover sizes refer to the van's body length only. Measure from the front of the body (not the drawbar or stone guard) to the rear of the body (not the spare wheel or bike rack). This is the measurement that tells you which cover size to buy.

2. Know your roof profile before you choose a cover type.

A full-height cover on a pop-top caravan will sit incorrectly and create loose fabric pockets that catch wind and pool water. Match the cover type to the roof style of your van. If in doubt, measure the overall height of your caravan when the roof is in its travel (lowered) position and compare it to the stated cover height.

3. Size up, not down, when between measurements.

If your body length measurement sits near the upper end of a size range, choose the next size up and add 15-20cm of allowance. A cover that is slightly generous is far easier to work with than one that is stretched tight and risks splitting at the seams or corner reinforcements.

4. Think about where and how you store the van.

A van stored under a carport or in a shed may only need cover protection during transport or occasional outdoor periods. A van stored on a driveway or in a paddock in full sun year-round needs a cover with the highest UV rating you can find, particularly on the roof panel.

Australian UV conditions are among the harshest in the world, and paint, seals, and rubber fittings all degrade faster under prolonged direct sun.

5. Consider ATM and payload before buying a heavy cover.

A heavier cover stored inside the caravan while travelling affects your available payload. ATM minus Tare Mass gives your usable payload capacity, and on many mid-size touring vans that figure is already heavily committed by water, food, clothes, and gear. A 13kg cover is not a major issue on its own, but it is worth knowing the number before you load up.

6. Check access features if you need to enter the van with the cover on.

Some covers include zippered panels along the side wall that allow you to enter the van without removing the entire cover. If you access the van regularly while it is stored, this feature saves a lot of time and reduces the wear and tear that comes from fitting and removing the whole cover repeatedly.
