How to Measure for RV Slide Out Awnings

If you own an RV, you know how important it is to have proper protection for your slide outs. Slide out awnings help prevent debris and water from accumulating on top of your slide outs, which can cause damage over time. However, in order to ensure a perfect fit, it is crucial to measure your RV slide outs correctly before purchasing and installing the awnings. Here’s a step-by-step guide on how to measure for RV slide out awnings:

1. Gather the Necessary Tools

Before you begin measuring, make sure you have the following tools handy:

  • Tape measure
  • Pencil and paper
  • Ladder (if necessary)

2. Identify the Type of Slide Out

RV slide outs come in different configurations, so it’s important to identify which type of slide outs you have before measuring. There are generally two types: box-style and flange-style.

Box-style slide outs have a rectangular shape with straight edges. Flange-style slide outs, on the other hand, have an angled flange along the top edge.

3. Measure the Width

Start by measuring the width of your slide out. For box-style slide outs, measure from one end to the other in a straight line. For flange-style slide outs, measure from the outer edge of the flange on one side to the outer edge of the flange on the other side.

4. Measure the Projection

The projection refers to the distance between the RV and the outermost point of the slide out when it is fully extended. To measure the projection, position yourself at the corner of the RV where the slide out is located. Measure from the side of the RV to the outermost point of the slide out along a straight line.

5. Determine the Fabric Size

Next, you need to determine the size of the fabric needed for your slide out awning. To do this, add 6 inches to both the width and the projection measurements. This additional fabric will provide sufficient coverage and allowance for installation.

6. Consider Other Factors

Aside from the measurements, there are a few other factors to consider when choosing a slide out awning for your RV. These include:

  • Color and design preferences
  • Quality of materials
  • Price range

7. Seek Professional Advice

If you are uncertain about the measurements or have any questions regarding the installation process, it’s always a good idea to seek professional advice. RV experts or dealerships will be able to guide you through the process and provide recommendations based on your specific needs.
