Below are the different types of windows and their corresponding standard heights and standard widths that you can choose from.


What Is The Standard Living Room Window Size?

The size of the window in your living room should be wide and tall enough to allow as much natural light to come in which usually ranges on average from 24 to 96 inches wide and from 12 to 96 inches in height. These ranges are pretty broad because every space is unique and therefore each has different window size needs as well. However, the most important thing to remember is to choose a window size that will not only bring in as much light as possible but also a window size that will perfectly fit into your space. Having more windows is always a better option than having blank walls in your living room because a well lit space reduces anxiety and stress levels plus it definitely increases home value.


What Are The Different Living Room Window Size And Styles?

Single Hung Windows

Single hung windows have one sash that is movable and can open from the bottom only. The standard width of a single hung window ranges from 36 inches to 84 inches and the standard height is between 24 to 60 inches. These types of windows are commonly seen in older homes because back then, they were one of the most common window types.

If you have ceilings of normal height and you are dreaming of having floor to ceiling windows, consider a stacked window design. To do this you combine single hung windows with a fixed window just like the picture above. The stacked window concept will provide a very bright and modern feel to any space. For smaller rooms, choose wider and shorter windows because this combination will make your space feel much more open.

Double Hung Windows

These are the common replacement windows in the United States. Double hung windows have two movable sashes which can slide up and down. The two main parts of the double hung window, the top sash and the bottom sash, can both be opened to provide enough of an opening for the fresh air to come in. The standard window size for this type of window varies anywhere from 24 inches to 48 inches wide and with the window heights between 36 inches to 72 inches.

Picture Windows

If you are looking for windows that will add architectural appeal and will bring more natural light into your living room, a picture window can be the window you are looking for. Picture windows come in a wide variety of sizes and styles. In most cases, when you see a borderless window that looks like a frame, then you are most likely looking at a picture window. They come in a wide range of sizes and often are used as living room windows. Below are the most common standard picture window widths and heights:

  • Standard Picture Window Widths – 24 inches, 36 inches, 48 inches, 72 inches, and 96 inches
  • Standard Picture Window Heights – Minimum height of 12 inches up to 96 inches maximum height.

If you have a rough opening that can fit one of the picture window sizes, grab this opportunity to get it because you are lucky enough to have a picture window in your living room without paying additional costs for a custom size picture window.

A good set of picture windows results in an effortless and modern styling living room.

Sliding Windows

These kind of windows are commonly used as kitchen windows, bathroom windows, as well as bedroom and basement windows. Slider windows open on side only because the sash window moves from left to right. They are typically windows that are wider than their height. Modern sliding glass windows provide high quality thermal insulation which makes them very energy efficient but aside from that, sliding windows are much easier to use compared to double hung windows. They open horizontally through sliding the sash back and forth, rather than moving the sash up and down.

  • Standard Sliding Window Widths – 36 inches, 48 inches, 60 inches, 72 inches, and 84 inches
  • Standard Sliding Window Heights – 24 inches, 36 inches, 48 inches and 60 inches

Bay Or Bow Windows

Just like picture windows, bay windows also add more architectural style than other common types of windows. They are built using two angled windows framing a picture window that are parallel to the inside wall of the house. The front center window is a non-opening and fixed window while the side windows can be opened to allow air circulation in the house. These typically come in different shapes such as square, hexagonal or octagonal and with window width ranges from 36 inches to 126 inches and height ranges from 36 inches to 78 inches.

Bow windows consist of four or more window units to create the effect of one large bow or curve-shaped window. Not all bow windows are operable for ventilation and they have a narrower window seat when compared to the large window seat that a bay window provides.

Bay or bow windows are windows that create a sense of grandeur and space which are compatible with traditional style homes. However, they also work very well with Victorian, Queen Anne and Tudor Revival homes.

Casement Windows

Casement windows open like a door because they swing wide, providing enough opening for better air circulation. This is an ideal window for you if you would like your window to provide plenty of ventilation. The standard casement windows are usually 14 inches to 35.5 inches wide and 29.5 inches to 77.5 inches tall.

Combining casement windows and picture windows will create windows that are perfect for a mid-century modern design home because of their clean and minimalist aesthetic.

Awning Windows

These type of windows are often used with other window styles. They are easy to open and close and because they open outward, you can open them during light rain. The standard awing windows are between 18 inches to 46 inches wide and 22 inches to 94.48 inches tall.

When paired with a casement window, it will become a window perfect for modern craftsman-style bungalows.

Sliding Glass Doors

Sliding glass doors are definitely not windows but can function as doors and as large windows for your living room. They are great options for smaller homes because sliding glass doors make your space feel much more open and are guaranteed to bring more light into your living room.

Living Room Window Size

The above pictures are the before and after photos of our living room and dining room area. The before picture, the wall separating the dining room and the back porch had two smaller windows with a single door. We decided to replace that whole wall space with two sliding doors because I really wanted to have floor to ceiling windows and at the same time, I wanted to have easy access from the living room to the back porch. In order to achieve that we utilized sliding glass doors.

Although, we bought pretty inexpensive sliding doors, we still ended up paying a lot of money because of the structural changes that our contractor made to create the look of two big windows. However, it is definitely worth the investment because our small living space does not feel small at all because there is a lot of natural light coming in. Aside from that, the sliding doors help our space to have a clean and modern architecture feel.

Custom Windows

If for some reason your living room has a rough opening that standard sized windows or the average window size will not fit, you will have two options. The first option is for you to adjust the window opening to fit the standard window size. However, if the adjustment of the window opening is complicated or more expensive, the second option, which is to order a custom window, will be a great option for you.

You can order the custom window from Home Depot, Lowes or your local window company. They will usually offer to measure your windows for free and then they will give you choices of what frame materials and glass you would like to have for the specific window type. After ordering, the windows will be made and shipped in several weeks. You will then be given an option to have the window directly delivered to your home or you can pick them up at the store and have them install the window for you for an additional cost. The cost of the custom windows are highly dependent on the size and type of windows that you would like to have.


Do Windows Need To Be Centered On A Wall?

The straight and the only answer is yes. Windows need to be centered because if they’re not centered, it will make the room look odd. It can also make the room feel like something is missing or undone. Centered windows give a simple and elegant look to any space even when utilizing only a few windows on a wall. It is necessary to keep all of them centered and aligned to make your windows eye appealing.

The above photo is an example of windows that were installed uncentered. Do you like what you are seeing?

Putting windows in between the fireplace is always a beautiful exemption to the rule. This is because the windows beside a fireplace will function as a frame to highlight the beauty of the fireplace.


What Is The Proper Window Spacing?

Designing living room windows is very important. Windows should be aligned evenly to give your living room space a well-planned look. In order to achieve a cohesive look, windows should be divided between singular and panel styles and spaced out correctly even when creating wall windows.
