    UK Caravan Awning Size Guide – Find the Perfect Fit for Your Full or Porch Awning

    Looking for the right size awning for your caravan? Whether you’re after a full awning for extended stays or a porch awning for weekend getaways, our UK Caravan Awning Size Guide makes it easy to find the perfect fit. With over 40 years of combined experience and access to a comprehensive UK caravan database, we take the guesswork out of awning sizing.

    In this guide, you’ll learn how to measure your caravan for both full and porch awnings, understand A-measurements, and use our easy-to-read awning size chart. Plus, with our Fitment Guarantee and Free UK Delivery, you can shop with confidence.

    📏 Measuring for a Full Caravan Awning

    Your caravan’s A-measurement is the key to finding the correct size full awning. This ensures a snug, weatherproof fit that maximises your comfort and space.

    🛠️ How To Measure
    (Step-by-Step – The Hard Version)

    • Park your caravan on level ground.
    • Thread a string (ideally 10m+)  through the entire awning rail from one end to the other.
    • Keep your fingers crossed, you measured correctly.

    📏 Porch Awnings are more flexible.

    However a bit of careful consideration will pay off with a perfect fitting Porch Caravan Awning and years of Hassle Free Camping!

    🛠️ How To Measure and What to Look Out For

    • Height from ground to awning rail (H)
      Typically between 235–250 cm for most UK caravans.
    • Length of the straight section of the caravan awning rail (L)
    • Position of Windows & Doors to ensure good seal and weatherproof camping.

    😌 The Easy Way…

    Sit back, relax, and let us find your perfect awning!

    With access to a huge UK caravan database and over 40 years of combined experience in the trade, we can take the guesswork out of sizing.

    Quest Neptune 400 Velcro Groundsheet – Deluxe Sewn-In Style Awning Flooring for Neptune 400 Air Awning


    Quest Neptune 400 Velcro Groundsheet – Deluxe Awning Flooring System

    Upgrade your camping comfort with the Quest Neptune 400 Velcro Groundsheet, a purpose-built deluxe flooring system designed exclusively for the Quest Neptune 400 Performance Air Awning.

    Unlike standard universal groundsheets, this premium fitted groundsheet has been custom engineered to perfectly match the footprint of the Neptune 400 awning, ensuring a seamless and weatherproof interior environment.

    Constructed using strong, durable materials with a soft rubberised finish, the groundsheet provides a comfortable feel underfoot while remaining highly resistant to wear, moisture, and outdoor debris. This makes it ideal for both short touring trips and extended campsite stays.

    Installation is quick and effortless thanks to the Velcro-in attachment system, which secures the groundsheet neatly around the inner base of the awning. This design creates a tight weather seal, helping prevent rain, drafts, and insects from entering the living space.

    The groundsheet has also been precisely tailored around the air tubes, using a practical toggle and loop system that maintains a clean appearance while preserving the protective seal.

    For added versatility, the entrance area features a clip-up doorway section. During wet weather, the edge can be raised to stop rainwater from entering the awning. On dry days, it can be unclipped and laid flat to eliminate trip hazards and allow easy access.

    A separate groundsheet for the tunnel section is also included, ensuring the walk-through area between the motorhome and awning remains dry and protected.

    This thoughtful design makes the Quest Neptune 400 Velcro Groundsheet one of the most practical and comfortable awning flooring solutions available for modern inflatable awnings.

    Why This Groundsheet Is a Must-Have

    For motorhome campers using the Neptune 400 awning, this fitted groundsheet ensures the entire awning and tunnel area remain clean, dry, and comfortable, even during wet weather.

    Whether you’re relaxing inside the awning, storing camping gear, or using the space as an extended living area, this deluxe flooring system delivers practical protection and enhanced comfort on every trip.
