Standard Canadian Window Profiles

Though window styles can vary greatly, most homes are equipped with windows that are standardized to fit certain popular sizes. Before doing anything else, measure the windows you’re wanting to replace in your Calgary home. Though some occasionally run into a non-standard size, you will likely find that your windows match one of the following standards.

Standard dimensions and glazing options for fixed picture windows are as follows:

Dimensions (In) Low Profile Glazing Dimension (1.5in frame) High Profile Glazing Dimension (3in frame) Surface Area Low vs. High (In2) Percentage Difference
24×12 21×91/8 181/16×61/16 191.63 vs. 111.76 71%
24×24 21×211/8 181/16×181/16 443.63 vs. 328.51 35%
24×48 21×451/8 181/16×421/16 947.63 vs. 762.01 24%
48×48 45×451/8 421/16×421/16 2030.63 vs. 1774.51 14%
72×48 69×451/8 661/16×421/16 3113.63 vs. 2787.01 12%  

Some alternate styles, such as awning or casement windows, will have different measurements.

Standard widths can range from 36” to 78”. Heights can vary even more, from 48” to the extra-tall 80” window. On occasion, however, custom windows may be used instead of standardized styles in order to achieve a certain aesthetic. 

Bear in mind, a poorly fitted and installed window or door may not be noticeable to the naked eye. Your wallet, however, will notice due to higher energy bills. Badly fitted windows could also decrease your property value. This is why it’s always a good idea to choose a trustworthy and professional window and door provider like Window Mart.

A few other handy window terms to get acquainted with

Casing: Casing is the plain or intricately designed trim around your windows. Casing dimensions can vary by manufacturer, but typically vinyl casings are 3 ⅜” or 2 ⅝” and rounded windows are almost always 2 ⅝”.

Brickmould: Brickmold is what moulds your windows to your home and is paramount to assuring your windows are secure, air-tight, and energy efficient. It’s usually best to select a brickmould strip that matches the brickmould on your current windows.

Jamb Extensions: Jamb extensions help cover rough openings created when connecting your window to the casing. Their size depends on the width of the windows and wall construction.

Canadian Regulations

Another key point to remember when selecting new windows for your home in Calgary is that your windows must comply with Canadian laws and regulations on a local and national level.
