How to Measure Windows for Replacement

Spring is right around the corner so you may be thinking about replacing your old windows, so here’s some tips on how to measure windows so you can get a quote on the correct sized replacements the first time around.

Once you know how to measure windows, you’ll be able to call in an order in no time, but don’t worry Polar will also measure so we eliminate any sort of error.

Note: Window measurements are always given width first, then height.

Step 1. All measurements should be done from the exterior so open the window, head outside with paper and pencil and remove the screen. To make it easier draw a diagram.

Step 2. Measure the distance between the top of the structural window opening to the bottom.

Step 3. Take three separate measurements from jamb face to jamb face- at the top, middle, and bottom. When you are looking at the jamb face, you will see that there is a small vertical lip in the middle that acts as a guide for the window. You do not want to measure from that lip. You want to measure from the most flat, recessed portion of the jamb face. Record the smallest of these numbers as the width (w). Then take three measurements from the bottom of the head to the top point of the sill slope – at the left, middle, and right. Record the smallest of these numbers as the height (h).

Measuring your windows is that simple!
