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…

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.
