    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.

    All we need is your caravan make, model, and year of manufacture—and we’ll do the rest!
