What Is The Standard Window Height?

What Is The Standard Window Height

Windows come in various styles, but many manufacturers provide windows with standard dimensions to make choosing windows easier on your wallet. Of course, you can always opt for custom-sized windows, but you’ll pay a pretty penny. Therefore, first look at window options that will fit into your existing standard rough openings or window frames.

Standard window heights vary based on the style of the window. For example, single and double-hung windows typically come in standard heights of 36, 44, 52, 54, 62, and 72 inches. Larger picture windows can range from two to 8 feet tall, while sliding windows are 24, 36, 48, or 60 inches tall.

These are some of the most common window styles, but there are also bay windows, awning-style, and casement windows. If you’re planning on installing or replacing your windows, it’s best to know all of your options. So, it’s time to get better acquainted with various windows and the available standard window heights.

The Standard Window Height Of Different Windows

Not every window is the same, so you can expect a variety of sizes. If you’re working with existing rough openings, you’ll likely look for windows that will fit the existing space. In some cases, this can limit your choices of window styles unless you plan to adjust the opening and pay more.

Keep in mind, a window’s actual measurements are typically a ½ inch less than stated. This ensures they can easily fit into the standard rough opening after installing flashing and other materials. So, a 36” x 36” window is actually 35 ½” x 35 ½”, a 36” x 48” window is really 35 ½” x 47 ½”, and so on.

Here’s a closer look at the standard sizes of the most popular window styles so that you can determine your available options.

1. Single And Double-Hung Windows

These windows are some of the most common types you’ll find in homes. Single-hung windows typically open from the bottom by lifting up the lower pane of glass. Double-hung windows open from the bottom and the top, hence the name.

The standard heights of single and double-hung windows are 36, 44, 52, 54, 62, and 72 inches. This makes the actual height of the window ½” less than these numbers.

The standard widths of single and double-hung windows are 24, 28, 32, 40, 44, and 48 inches.

2. Fixed (Picture) Windows

If you want to take advantage of excellent views, picture windows offer an unobstructed view of the outside. They’re also a great way to bring lots of natural light into your home. Picture windows can be larger since they are a single piece of glass and do not open.

The standard heights of fixed windows are anywhere from 12 inches up to 8 feet tall. Some of the most common heights are 18 inches, 2 feet, 52 inches, 54 inches, 62 inches, and 8 feet.

Picture windows feature standard widths of 2, 3, 4, 5, 6, and 8 feet.

3. Sliding Windows

Sliding windows get their name from how they open by sliding the glass either left or right. Because of how they open, these windows are typically wider than their height.

Standard heights of sliding windows are 24, 36, 48, and 60 inches. The standard widths of sliding windows are 36, 48, 60, 72, and  84 inches.

4. Awning Windows

Awning windows are a great way to open your window while shading your home from the sun and the rain. These windows are hinged at the top and extend outward and upward.

Awning windows have standard heights that range from 1 ½ feet to 7 feet, 8 inches. The standard widths of awning windows range from 2 feet to roughly 3 feet, 10 inches.

5. Casement Windows

Casement windows open outward from the sides on hinges. You can have a single casement window or double (twin) casement windows.

Some common heights for single casement windows are 45 or 53 inches. Double casement windows come in heights of 35, 47, or 59 inches.  But standard heights can range from 2 feet, 5.5 inches to 6 feet, 5.5 inches.

Popular widths for casement windows are 21, 25, or 29 inches. But standard widths can range from 1 foot, 2 inches to 2 feet, 11.5 inches.

6. Bay Windows

Undoubtedly bay windows add a special touch to any room, letting in lots of light. They’re also a great way to add character and architectural detail to your home.

You can find bay windows in various sizes, with standard heights ranging from 3 to 6 ½ feet tall. Standard widths of bay windows also vary, ranging from 3 ½ feet to 10 ½ feet.

How To Select The Right Size Windows

Remember, the actual size of a window will be about ½ inch less for both the width and height. So, if you have a rough opening of 3 x 3 feet, you would need a 3 x 3-foot window. However, the actual window would measure 35 ½” x 35 ½”.

The window size translates to a certain model number used by many window manufacturers. In this example, a 3 x 3-foot window would be called a 3030. This four-digit number simply represents the window’s width and height.

So, a window that is 28 inches wide and 36 inches tall would be a 2430 (2 feet, 4 inches by 3 feet). If the particular windows you’re looking at don’t have these types of numbers, provide the manufacturer with your measurements.

Or you can also tell them the model number as mentioned above. Based on this information, they can help you find a comparable size among their unique model numbers.

What If You’re Measuring For Replacement Windows?

Take care when taking measurements for replacement windows. You don’t want to end up getting a window that is about a ½” off from the necessary size. For this reason, you should take several width and height measurements to determine the smallest dimensions.

So, first, measure the width of your window, frame to frame across the top, middle, and bottom. Then, measure the height of your window, from frame to frame, at a minimum of two pints. If you have a very wide window, take height measurements at three points.

Make a note of all your measurements; you might be surprised to find a .25 to .5 inch variance. Select the smallest width and height measurements to determine your new window size.

If necessary, you can add shims to fit the window. It’s much easier than trying to enlarge an opening for a window that’s .25 too big.

But, don’t be fooled. Although it might sound simple, measuring for windows, whether brand new or replacement, can be challenging. If you are uncertain, it’s best to hire a professional installer to take the measurements for you.

Frequently Asked Questions

How far should a window be from the floor?

This measurement can vary based on many factors, including the size of the window, size of the room, ceiling height, and window style. Typically, the top of the window frame is equal to the door frames in the room. So, you could determine your floor-to-sill height from there based on your window size.

For example, if you have a standard 7-foot door frame, the top of the window will be 7 feet from the floor. If you have a three-foot-tall window, then the sill would be roughly four feet from the floor.

However, if you have a four-foot window, the sill would be about three feet from the floor. If you have a privacy window that is two feet tall, then the sill would be five feet from the floor. 

How much do replacement windows cost to install?

The average price for a replacement window, including the window and labor, can be anywhere from $200 to over $2,000. This is because there are a considerable number of factors that influence the price.

You have to think about the window size, material, style, special features, and any unique installation challenges. But, the average cost to replace a window is about $850.

Vinyl windows tend to be the more affordable, with wooden and fiberglass windows having some of the highest costs.

Bay windows will usually be on the more expensive side of the spectrum, with single-hung and fixed windows at the lower end. Casement, sliding, and double-hung windows tend to be just slightly more than single-hung and fixed windows.
