Choosing the right window sizes for your home can seem daunting, but understanding standard sizes can simplify the process. Standard window sizes refer to commonly manufactured dimensions that fit most homes. These sizes help ensure windows are easily replaced and fit typical architectural designs.

In this blog post, the window replacement experts at Zen Windows St. Louis discuss the standard sizes of some of the most popular replacement windows so you can understand what to expect when shopping for your new windows.

Sizes of Different Window Styles

Each window style has its own definition of what’s considered standard in terms of size. Below are some of the most popular window style options and their standard sizing:

Sliding Windows

Sliding windows operate by sliding along a horizontal track. They’re perfect for spaces where you need a wide, unobstructed view. Standard sizes for sliding windows include widths of 36, 48, 60, 72, and 84 inches and heights of 24, 36, 48, and 60 inches. Due to their ease of use and large glass areas, these windows are commonly installed in living rooms, bedrooms, and kitchens.

Casement Windows

Casement windows are hinged at the side and open outward like a door, operated by a crank. They’re ideal for areas where maximum ventilation is desired. Standard sizes for casement windows range from 17 to 41 inches in width and 16 to 33 inches in height. Casement windows are often used in kitchens, bathrooms, and hard-to-reach places because they’re easy to open and close.

Single- and Double-Hung Windows

Single- and double-hung windows have two sashes within a single frame, with single-hung windows allowing the bottom sash to move while the top sash is fixed. Double-hung windows allow both sashes to move. Standard sizes for these windows include:

  • Two feet wide by three feet high
  • Two feet wide by four feet, four inches high
  • Two feet, eight inches wide by four feet high
  • Two feet, eight inches wide by five feet, two inches high
  • Four feet wide by six feet high

These windows are versatile and commonly found in bedrooms, living rooms, and dining rooms.

Hopper Windows

Hopper windows are hinged at the bottom and open inward from the top. They’re typically small and installed in basements or bathrooms where ventilation is needed but space is limited. Standard sizes for hopper windows range from 30 to 36 inches in width and 12 to 24 inches in height.

Awning Windows

Awning windows are hinged at the top and open outward, resembling an awning when open. These windows are often used in conjunction with larger stationary windows to provide ventilation while maintaining protection from rain. Standard sizes for awning windows include:

  • Two feet, five inches wide by one foot, eight inches high
  • Two feet, nine inches wide by one foot, seven inches high
  • Three feet, seven inches wide by seven-foot, eight inches high
  • Four feet wide by one foot high

Window Sizes for Custom Homes

In some cases, standard window sizes may not suit your home’s needs, especially in older or uniquely designed homes common in the St. Louis region.

These window sizes allow for replacement windows that perfectly fit the existing frame, ensuring a seamless look and proper insulation.
