You can find sliding screen doors in widths like 72 inches which are quite common. However, it’s important to note that their aluminum frame height may vary depending on each door’s dimensions. When choosing a security screen for your sliding door make sure you carefully measure the height of your door opening to ensure a fit. Screens that are too short can create gaps that intruders could exploit while screens that are too long can be challenging to install and operate properly. The average size for a sliding glass door is about 60 to 72 inches in width and 72 to 80 inches in height, Home improvement stores like Home Depot offer common door sizes, such as 36 x 80 inches. We recommended measuring the door frame at least twice to ensure the proper fit!
