Ventura Awning Size Chart

Choosing the right awning size is key for both looks and protection. A well-fitted awning improves your caravan’s appearance while giving you the shade and shelter you actually need. With Ventura awnings, getting the size right means your Pacific or Cadet model fits properly and performs as it’s meant to.

Ventura Sizing System: The Link to Isabella's A-Measurement

Ventura awnings follow the same sizing principles used by Isabella, which means full awnings are based on the A-measurement system. This shared approach creates consistency across both brands and makes it much easier for caravanners to select the correct size with confidence, especially when replacing an older awning.

Defining the A-Measurement for Ventura Full Awnings

The A-measurement is taken from the ground on one side of the caravan, along the full length of the awning rail, and back down to the ground on the opposite side. This single measurement accounts for both the height and length of the caravan and forms the foundation of Ventura full awning sizing.

Converting Your Caravan's A-Measurement to a Ventura Size

Once your A-measurement is known, it can be matched directly to Ventura’s full awning size chart. Each size covers a specific A-measurement range, allowing you to choose the closest match for the best possible fit. This ensures the awning sits neatly along the rail and reaches the ground with proper tension.

The Ventura G-Numbering System Explained

Some Ventura awnings also reference a G-numbering system. This usually relates to the depth and profile of the awning rather than its overall length. While the A-measurement determines the main size, the G-number helps identify how far the awning projects outward and the internal living space it provides.

Essential Sizing Checkpoints and Errors to Avoid

Accurate measurement is essential for Ventura awnings to perform properly. Common mistakes include measuring on uneven ground, cutting across the curve of the rail, or forgetting to account for obstacles such as windows, vents, and guttering. Always double-check your measurements before settling on a size to avoid costly fitting issues later.

Air Awning and Porch Awning Sizes

Ventura air awnings and porch awnings are sized differently from full awnings. Rather than using the full A-measurement, these awnings rely mainly on the straight rail length and fitting height. This makes them more flexible and quicker to set up, which suits touring caravanners in particular.

Sizing the Ventura Air Series (Air Cito, Air Dove)

Ventura Air awnings such as the Air Cito and Air Dove are designed for fast pitching and touring convenience. These models are sized by their overall width rather than the full caravan A-measurement, making them ideal for owners who prefer flexibility and easier day-to-day use.

Checking Connecting Height (H) and Rail Length (L)

For air awnings, two key measurements are required. The connecting height (H) is measured from the ground to the awning rail, while the rail length (L) is the straight section of rail available for attachment. Both measurements must fall within the awning’s accepted fitting range to ensure a secure and weatherproof fit.

Choosing Between 2.5m and 3.0m Deep Ventura Awnings

Ventura awnings are commonly available in both 2.5m and 3.0m depth options. A 2.5m deep awning suits most touring setups and is easier to manage in windy conditions, while the 3.0m depth provides noticeably more internal space. This makes the deeper option popular for longer stays and seasonal use.

Frame Options: Prenox Steel vs. IXL Fibreglass

Ventura awnings are available with either Prenox steel frames or IXL fibreglass frames. Prenox steel offers maximum strength and is well suited to seasonal pitching, while IXL fibreglass is lighter and more flexible. This makes it ideal for touring caravanners who prioritise ease of handling and faster setup.
