How to Properly Measure Your Window for a Fabric Casement Kit

Don't suffer in the heat with crank-out windows! These simple, rental-friendly solutions will allow you to have a casement window air conditioner this summer! So, before ordering your fabric casement window kit for your portable air conditioner, you’ll want to get accurate measurements to ensure a proper fit. Here’s how to do it:

Step 1: Open the window fully

• Swing the casement window open all the way so you have full access to measure the entire opening.

Step 2: Measure the window height

• Measure from the very top of the window opening down to the very bottom.

• Record this measurement in inches or centimetres, depending on the kit specs.

Step 3: Measure the window width

• Measure from the inside edge of the left frame to the inside edge of the right frame.

• Again, write down this width.

Step 4: Check your measurements

• Double-check both height and width to avoid mistakes.

• If your window has any unusual shapes (like an angled top), measure the widest and tallest points to be safe.

Step 5: Match to kit specifications

• Compare your measurements with the size range of the fabric window kits we offer on itsonelectric.com.

• The kit should fully cover your window opening while leaving enough space to zip around the AC exhaust hose.

TIP: If you are between sizes, choose a slightly larger fabric kit — you can always overlap or adjust it to make a tight seal.
