21 products
A size 18 awning fits a caravan with an A-measurement of 1075-1100cm, which you'll tend to find on twin-axle caravans. Below you’ll find our full range of size 18 caravan awnings, from quick-pitch air awnings to poled awnings built for a seasonal pitch. Brands include Camptech, Dorema, Sunncamp and Starcamp.
Size 18 caravan awning: air, poled or seasonal?
Size 18 awnings come in three main types, and here is how they differ:
Measurements near the boundary? Check awnings that fit a size 16 rail and size 17 awnings too.
We also stock awnings that fit a size 15 rail.
Size 18 air awnings
An air awning has inflatable beams in place of poles, so it goes up faster and with less fuss. Our size 18 air awnings include the Sunncamp Icon Air and Esteemed Air, the Starcamp Valor Air, the Dorema Daytona Air and the Camptech Hampton DL Air.
Size 18 poled awnings
Poled awnings use a frame of poles and are a dependable choice for long stays. Popular size 18 options include the Dorema Monza 240, Monza XL 270 and Diamond XL 270, and the Camptech Cayman, a lighter touring awning.
Size 18 seasonal and all-season awnings
If your awning will stay up for months, look at the seasonal models. They include the Camptech Atlantis DL, Savanna DL and Mayfair DL, the Hampton DL Air and the Dorema Horizon Air De Luxe. Several of our size 18 awnings come with a free gift, such as a carpet, electric pump or storm straps, so check each listing.
Size 18 awning in cm: will it fit your caravan?
Awnings are sized by your caravan’s A-measurement. Measure from the ground at the front of your caravan, up and around the awning rail, then down to the ground at the back. If it falls between 1075cm and 1100cm, a size 18 caravan awning is the right fit.
| Size | A-measurement (Camptech, Dorema and most brands) | Dometic |
|---|---|---|
| 15 | 1000-1025cm | 990-1015cm |
| 16 | 1025-1050cm | 1015-1040cm |
| 17 | 1050-1075cm | 1040-1065cm |
| 18 | 1075-1100cm | 1065-1090cm |
| 19 | 1100-1125cm | 1090-1115cm |
| 20 | 1125-1150cm | n/a |
| 21 | 1150-1175cm | n/a |

What size is a size 18 awning?
