Are Window Sizes Standard Or Should I Measure Them Before Going To The Store?

To get a quote in store, you must know the dimensions of your windows (height, width, depth). The more precise the measurement, the more accurate the quote… which will avoid unpleasant surprises on the final bill!

Here are some helpful tips on how to measure your windows:

Height and length

To calculate the actual space available, include the height and length of the trim because this usually covers part of the wall opening.


This one is more complicated to measure. To accurately estimate it, open the door to your home and measure the distance between the interior and exterior walls.

You’re guesstimating? Don’t worry about it! Most retailers will go to your home to take exact measurements prior to installation. The objective here is only to get an accurate quote.
