Sliding Window Sizes

Sliding windows come in a variety of sizes. One of the reasons this is such a popular window type is because it can fit especially long and/or narrow wall spaces. Ultimately, your budget and the wall you are installing the window on will be the deciding factor on size. Here are all the sliding window sizes you can consider.

Sliding Window Sizes

The average size for sliding glass windows is a 48 inch x 48 inch sliding glass window. However, sliding windows can range in size from a horizontal width of 36″ to 84″, and a height from 24″ to 60″.

• The horizontal width of a sliding glass window can be 36 inches, 48 inches, 60 inches, 72 inches, and even as large as 84 inches.
• Your sliding window’s height can be 24 inches, 36 inches, 48 inches, or 60 inches tall.

Small Sliding Windows

These typically range in width from about 24 inches to 48 inches and in height from 12 inches to 36 inches.

Small sliding windows are ideal for areas where space is limited, or only a small amount of ventilation or light is needed. They are often used in bathrooms, small bedrooms, or for kitchen windows.

Large Sliding Window

Looking for something that lets in the most light possible? These can start from widths of about 48 inches and go up to 84 inches or more, with heights starting from around 36 inches to 60 inches or more. If you’re want something even bigger, you may want to talk to a window contractor about ordering something custom.

Large sliding windows can serve as focal points in a room and provide better ventilation compared to smaller windows. They are commonly found in living rooms, master bedrooms, or areas where maximized natural light and views are desired.

What Are the Most Popular Horizontal Sliding Window Sizes?

Of all the above options, most homeowners choose one of the following:

1. 24×48 slider window. These tend to be relatively inexpensive (under $200 in some cases) and can fit into small spaces. They are often used above tubs or showers, elsewhere in the bathroom, or in smaller areas that need light and ventilation.
2. 60 x 48 sliding window. These larger sliding windows are a good choice for dining rooms, larger kitchens, living rooms, and bedrooms. These windows also meet egress requirements (as would any slider window that is 48 x 48 or above).
3. 72 x 60 slider window. This large window still comes as a standard size from many manufacturers and is used often in living room and bedroom window replacements.
