MEASURING A CARAVAN FOR A FULL-SIZE AWNING

The universal and most reliable method for measuring a caravan awning is to use the caravan's A-Measurement. All full size awnings are categorised by the caravan’s A-Measurement Size.

How to measure a caravan’s A-measurement

A caravan’s A-measurement is the distance in centimetres from ground level, going up and then all the way around a caravan's awning rail and back down to the ground again at the other side.

Your caravan’s rail measurement should be contained in the owner's manual, on the page listing the caravan’s dimensions, this is shorter than the A-measurement. You can easily measure the A-measurement yourself by using a tent peg, tape measure and a ball of string.

Firstly, put the tent peg into the ground directly below the awning rail entrance at one end of the caravan. Then, tie the end of the string to it. If you don’t have a tent peg or if the ground is hard, just secure the string with a small heavy implement.

Next, feed the string all the way around the awning rail, all the way along to the ground at the other end of the caravan. If the awning rail has a prominent curve at the bottom sections, simply let the string drop down to the ground as in the diagram.

Cut the string where it meets the ground and measure it in centimetres. This will give you your caravan's A-Measurement which is your caravan full awning size. This measurement will fall into a range of standard awning sizes – i.e. if your A-measurement is 970cm, you would select your awning from the 950-975cm range. Sometimes, however, your A-measurement may be at the point between awning size ranges, in which case you should opt for the larger size. A larger size will allow for a bit of slack and also give you some room for maneuver, which could be useful on an uneven pitch.

MEASURING A CARAVAN FOR A PORCH AWNING

Measuring your caravan for a porch awning is very different to measuring for a full awning, as a Porch doesn’t wrap all the way around one side of your caravan. This type of awning is usually secured to the ground with pegs or guide ropes, similar to a tent.

The size you need for a Porch Awning relies on two measurements:

1) The height measurement (H), which is taken from ground level vertically up to the awning rail (H)

2) The length measurement (L), which is the straight section across the top of the awning rail.

There are however more things to consider when measuring for a Porch Awning. The most obvious is that the door should be within the section measured so that it opens comfortably into the porch. Also, ensure that side windows and refrigerator vents are taken into account and not obscured.

In the diagram example if a Porch Awning measuring the full length of L2 was fitted, the side wall of the awning would prevent the window from opening. Therefore, to ensure the window opened, you would need to measure the length from the point where the window begins (L).

MEASURING A MOTORHOME FOR AN AWNING

Most awnings for a motorhome fit best when using a Fiamma or Thule awning channel or driveaway kit.

There are options available such as magnetic driveaway kits or tie down straps which are thrown over the vehicle and pegged down if you do not have an awning channel available.

Measuring your motorhome to fit an awning requires two key dimensions as well as the consideration of fitment.

1 ) The height measurement (H) which is taken from the ground level vertically up to the fitment height (i.e awning channel). This is crucial to choosing the correct awning. This often varies depending on whether the vehicle is loaded or unloaded.

2) The length measurement (L) us normally used when sizing a fixed awning. More drive away awnings will take a similar length of rail but use a driveaway kit in between, therefore requiring approximately 3 meters of rail.
