Standard Window Width:Choosing The Right Style For Your Home

Standard window width often changes. When building a home, one of the first things you need to figure out is the width of your windows. Before you begin designing your home, you’ll need to follow the window size notation or window sizing process.

Standard Window Width

Establish your window openings and window dimension for each room. When replacing windows, if you choose different windows, then you’ll need the actual measurements for each space. Home windows with rough openings will be more difficult than installing common window sizes.

If your window measurements are wrong, your house will not be balanced. It’s essential for you to choose and measure which window style you want for your living space as example, and their sizes.

What Is The Standard Window Width?

Window width sizes range between 36 inches, 48 inches, 60 inches, 72 inches, and 84 inches. However, with common window sizes, most windows in US households are 36 inches wide. The standard window height is between 36 inches to 60 inches. You’ll notice that windows appear wider than they are tall because they’re assembled according to width, not height.  

Half Inch Rule For Window Dimensions

Half Inch Rule For Window Dimensions

Window manufacturers rely on window size notation for replacement windows. The purpose is to help you identify the window size for a rough opening. A window’s size notation is a combination of width and height.

The first two numbers are for width and the second two numbers are for height. For example, a 2628 replacement window would have a width of 2 feet and 6 inches and a height of 2 feet and 8 inches. Don’t forget that the measurements of the window are a half inch less than the whole number that identifies the window.

If a window says it’s 36 inches wide, it will 35.5 inches wide. Manufacturers know you need to take your window frame into account. Custom windows are different as they’re made specifically for your home. 

You can use a shim to stabilize the window before using caulk or foam to seal it. After you apply the facing, you’re done. For more info and help on installing windows and doors, check out this guide

A single hung window are made with a single movable sash and are raised from the end for ventilation. Similar to fixed windows, the top remains stationary. This is one of the cheapest window types and the most common.

When “average window size” is discussed, it’s this the window they’re talking about because it’s a standard window. The easiest way to tell if you have a single hung window is to look below the top sash on the exterior of the window. Double-hung windows have a small space between the sash and the jamb so slides up and down.

Double Hung Windows

  • Price: $450 to $600 per window
  • Width: 36 inches to 84 inches 

Double hung windows have two operating sashes. This allows for ventilation from the top, bottom or both. Since both the top and bottom open, they offer more ventilation and easier cleaning than single hung windows.

The windows are almost as popular as the single hung window style but they’re twice as expensive. Double-hung windows will have a small space between the sash and the jamb allowing it to slide up and down.

Double hung window sizes start at 24 inches and can go up to 48 inches horizontal. The standard bedroom window size is 24 inches x 36 inches.

Awning Windows

Awning windows are one of the few windows that are wider than they are tall. They are hinged on the top and open outward from the bottom. This allows protection from bad weather, which is why you can open them when it’s raining, for example.

An awning window is a popular garage and basement window where the top of the basement walls are above ground. 

Bow Windows

Arched Windows

  • Width: 24 inches to 192 inches. 

An arched window is used for aesthetic purposes rather than practical reasons. They make or break a design style, being found in both Victorian homes and Mexican homes. They can be found in almost any size and often have ornate features. They’re often installed in living rooms and are a popular home improvement project.

Unlike an awning window, arched windows don’t have to be round on top but they do need to be curved, even if it’s just a metal bar. Your window measurements will need to be exact and may require flashing materials. 

Casement Windows

  • Price: $270 to $750 per window
  • Width: 12 inches to 36 inches per window

Casement windows are the oldest movable or adjustable windows. The hinges move on the upright side of the vertical sash. They open like French doors, making them look much nicer than standard windows.

Glass Block Windows

Jalousie windows are very uncommon for multiple reasons. They are made up of multiple glass slats that open and close like blinds. They aren’t the most secure windows and they don’t offer much protection from the elements.

The mullion can be standalone and so can the transom, but they were designed to work together.

Hopper Windows

  • Price: $265 to $720 per window
  • Width: 14 to 50 inches

A hopper window is simply an awning window that opens from the bottom instead of the top. They make it easy for smoke to escape and are great for letting sunshine and fresh air inside. They look just like an awning window when closed. 

Like awning windows, they are generally smaller than other windows because they are primarily for ventilation rather than looks or letting light in.
