Common Casement Window Sizes

Casement windows come in several common sizes, the better to serve the majority of homeowners. But in addition to the more common sizes, there are options for custom-made windows that can fit almost any home.

Most Common Casement Window Sizes

The idea of standard window sizes is considered a myth to some in the homebuilding industry. However, most homes are built to a certain code or standard, and those standards are what the window industry caters to most often. Window dealers often choose a set of standards to which they build all their windows, no matter what the type, and then offer custom sizes for those that fall outside that range.

What is the typical range? Most manufacturers make casement windows that are between 24 inches and 30 inches wide, with a height between 48 and 56 inches. Bay windows, bow windows, and picture windows cater to much larger standard sizes.

Common sizes for casement windows in basements usually range from 18 to 24 inches wide by 12 to 18 inches high. Before you place that order for a casement window, consider the required amount of space necessary to exit. Talk to your local building inspector to make sure of the standards your windows must meet.

Custom Casement Window Sizes

What about those custom windows that you can't find in any warehouse? Custom casement window sizes are available for most homes through reputable dealers. If you can't get the custom size you require, consider using two or three common sizes for casement windows, side by side or placed one above the other, in order to fill the window area.
