Standard Sliding Patio Door Size (Complete Guide)

Installing a patio door in your home that is the appropriate size can significantly enhance both the appearance and the atmosphere of the interior spaces. The patio door will act as a passageway that connects the interior of the home to the exterior yard space. 

It is essential to determine the suitable size for your home in order to give the impression that it is larger and more appealing. A sliding patio door is your best option if you are limited in the amount of floor space that you have available.

The height of a sliding patio door can most accurately be determined by looking at the ceiling of your property. Both of these metrics have a strong positive correlation with one another. 

Because the ceiling is often between 8 and 10 feet high, the height of the sliding door will typically be around 80 inches, which is equivalent to 6 feet 8 inches. However, places with higher ceilings will require doors of a larger size to accommodate them. 

As a direct consequence of this, the typical heights of doors sold commercially are either 96 inches or 80 inches. Additional headroom may be required for customized doors that include a top window that adjoins the door. 


The width of your sliding glass door will be determined by the number of panels you choose to have in it. Patio doors will typically consist of two separate panels. In this situation, one door opens and closes by sliding behind the second door, which is located in the opposite direction. 

Doors that have three panels allow only the two outermost panels to open and close, while the panel in the center remains fixed. 

Sliding doors that have two panels will often have a width of sixty inches, seventy-two inches, or ninety-six inches, while sliding doors that have three panels will typically have a width of either 108 inches or 144 inches. 


The typical measurements for the height and breadth of sliding patio doors are 80 inches and 60 inches respectively. Nevertheless, the width and height of a patio door might differ from one manufacturer to the next depending on the specifications of the door. 

It is possible for the width to be either 72 or 96 inches, while the height might be 96 inches. 

What is the rough opening for a sliding patio door?

Simply said, a “rough opening” refers to the unfinished woodwork that will serve as the location for the door once it has been placed. A standard sliding patio door will have rough opening measurements that are greater than 60 inches wide and 80 inches high on average. 

This is the dimension that is typically considered to be the standard for a track for a sliding door. 

Rough apertures are normally larger in height and width by two inches than the door that will ultimately be installed. Simply adding two inches to each measurement will allow you to get the general opening measurements based on the size of the door. 

4 factors that determine sliding patio door size 

Sliding doors are the most common type of door because they are inexpensive. The beautiful looks of these patio doors are matched by their practicality. Choosing the right size for your patio door depends on a few different variables. For instance, 


The two most common varieties of patio sliding doors are single- and double-sliders. The door sizes available to you will depend on the style you choose. There are two distinct types, one with two panels and the other with three. Doors with two panels are the norm. 

When opening and closing a two-door section, one door slides behind the other. Doors with three panels allow the outer two to open and close while the middle panel stays stationary. 


When there is a limitation on the amount of available floor space, sliding doors are an excellent choice. When a conventional swinging door would be too large for a particular space, such as on a balcony or in a sunroom, these doors are an excellent alternative. 

Because a sliding door does not prevent any natural light from entering the room, the room will appear to be larger than it actually is. 


The beauty of your home’s inside can be accentuated with the installation of the proper sized sliding patio door. If you can find one that works with the design of your home, a sliding patio door is a sleek option for achieving a minimal appearance. 

Sliding glass doors let in light from outside and give the illusion of additional space in a room. This setting will put you in a prime position to take in the sights of your immediate surroundings. 

The environment will lift your spirits and provide you more room to throw a party. 


The size of the sliding door you intend to install is a significant consideration. Fortunately, sliding glass doors come in a wide variety of standard sizes, making it simple to purchase suitable replacements when the time comes.
