How to Measure a Casement or Awning Window

Have you received an estimate range for a casement or awning AC window panel? You can use the measurements of your window opening to identify which price tier applies. This is optional and takes only a few minutes.

Measure your window opening

Open your outward-opening casement or awning window fully. Measure the inside width from left to right and the inside height from top to bottom, using inches. Use the illustrated guide below to see where to measure.

How to measure the width and height of an outward-opening casement or awning window opening, calculate square inches and identify the price tier

Calculate the opening area

Multiply the width by the height to calculate the opening area in square inches.

Example: 22 inches wide × 36 inches high = 792 square inches.

Find your price tier

Compare the total square inches with the casement and awning pricing chart in your Aircon Rescue estimate email or on our Pricing page. In this example, 792 square inches falls into the over 600 to 1,000 sq. in. tier.

You don’t need to email us your measurements. This guide is simply here to help you narrow your estimate range.

What happens at your measurement appointment?

Our technician takes the exact measurements, checks window and hose compatibility, demonstrates the panel and confirms your final price during the home measurement visit (about 15 minutes). Your measurements are for estimating only.
