Common Sliding Patio Door Sizes

Are you planning to have new sliding patio doors installed at your home? If so, it helps to understand common sliding patio door sizes. Unlike replacement windows, which are custom-made to the precise dimensions needed for each window opening, patio doors typically come in standard sizes.

Two-Panel Sliding Glass Patio Doors

The most common type of sliding patio doors are two-panel doors. These doors feature two panels, one that remains stationary in place and another one that slides horizontally to open and close. Common sliding patio door sizes for this style include:

60 inches (5 feet) wide by 80 inches tall

72 inches (6 feet) wide by 80 inches tall

96 inches (8 feet) wide by 80 inches tall

These patio doors may also come in extra-tall options like 82 inches or 96 inches, but these are less common.

Three-Panel Sliding Glass Patio Doors

In addition to two-panel patio doors, there are also options for three-panel doors. These doors allow for a more panoramic view and a wider opening. Typically, one of the end panels will open, and then the middle panel can continue to open from there for an even wider opening. As you can imagine, the common sliding patio door sizes for three-panel door styles are wider. Common widths include 108 inches (9 feet) and 144 inches (12 feet) for three-panel sliding patio doors, with the same standard door heights as two-panel doors. While four-panel doors and higher are also available and feature even larger widths, these types of sliding patio doors are far less common in general.

Choosing the Right Patio Doors for Your Home

Choosing the right size of patio doors for your home is an important first step in your patio door replacement project. If you’re replacing existing sliding patio doors, you can simply measure the size of the existing opening. 

For a new construction home, there’s more opportunity to choose a different size of patio door. While this situation allows you to choose completely custom dimensions for your patio doors, it’s generally best to stick with one of the standard dimensions. If the patio doors ever need to be replaced, it will be easier to find a product that fits.
