If you've ever dreamed about peering into your garden from the comfort of your kitchen table, installing a sliding glass door can be the key to making it happen. Patio glass doors open up a space with ample sunlight while creating an easier pathway to and from your yard. Whether you're replacing your current glass sliding doors or are thinking about transforming a wall, here are the standard sliding glass door sizes to keep in mind.
Sliding Glass Door Dimensions
Sliding glass doors range from 60 to 144 inches wide and 80 to 96 inches high. When considering how to measure a door, keep in mind that the width covers the full distance between the outer frames, not just the width of each sliding panel.
Manufacturers stick to standard sizes for doors, windows, and cabinets for good reason. Standard sizes make the process of replacing a sliding glass door easier and offer a wider variety of styles that fit your home's design.
Sliding glass doors come in a few standard widths, heights, and layouts, as well as custom varieties. Let's take a look.
Sliding Glass Door Widths
The width of your sliding glass door will likely come down to how many panels you choose. Two-panel doors are the most common for patios. In this case, one door slides behind the other to open and close. In three-panel doors, the center panel remains in place while the surrounding doors open and close.
| Number of Panels | Typical Door Widths |
|---|---|
| Two-panel sliding doors | 60 inches, 72 inches, or 96 inches |
| Three-panel sliding doors | 108 inches or 144 inches |
Sliding Glass Door Heights
Since the standard ceiling height in a home is between 8 and 10 feet, sliding glass door heights typically fall around 80 inches, or 6-feet 8-inches high. Rooms with high ceilings or those looking for floor-to-ceiling doors may opt for taller glass doors. Taking all this into account, the standard sliding glass door heights are:
80 inches tall
82 inches tall
96 inches tall

A two panel sliding glass door is great for patios and other backyard entry. Depending on your home’s size and personal preference, there are a few options to choose from in terms of size. Standard two panel sliding glass doors are about 72 inches wide and 80 inches tall.

3-Panel Door Sliding Glass Door Sizes
A three panel sliding glass door is great for use as an entryway to backyards or patios in larger homes, or as a room divider. As a standard, these doors are 108 inches wide and 80 inches tall.
| Width (inches) | Height (inches) |

| Width (inches) | Height (inches) |
|---|---|
| 144 | 80 |

Custom Sliding Glass Door Sizes
On occasion, opting for a custom-sized sliding glass door will be the best option for your home and design. Perhaps you're hoping to transform an entire wall into wall-to-wall and floor-to-ceiling glass. Older homes may have different-sized holes in the wall as well. Or maybe you're looking to balance your door with existing windows.
In these cases, it's important to call a professional door installer to analyze your space before ordering the door. You may need a frame and panel in a custom size.
Some custom sizing options for glass sliding doors include:
Doors with four or five sliding panels
Bi-fold or telescoping doors
Frames with built-in lighting
Doors with adjoining windows
Doors with adjoining top window
Cost to Install a Sliding Glass Door
Installing a new patio door costs an average of $2,500 from start to finish. Sliding glass doors cost between $1,300 and $3,000. The size of your sliding glass door will play a role in the door installation cost, both because the frame requires more materials and the glass panels may be larger.
Keep in mind that opting for a standard sliding glass door size is a great way to save money on installation and parts. Not only will the manufacturer have more options of the standard sizes, but your contractor may not have to do additional work to an existing rough opening.
That being said, it's important to choose a door size that fits the aesthetic of your space, and in some cases, this calls for a door outside the standard measurements.
Frequently Asked Questions
The most common rough opening for a sliding glass door is 60 inches to 72 inches by 80 inches. A rough opening is the unframed space where your door will go.
Sliding glass doors list their measurements as width-times-height. They always include the full frame of the door from end to end, and not just the individual panels.
If you're measuring the doors in your home, measure the width from one side jamb to the other. Measure the height by starting at the bottom sill at the floor and all the way up to the top of the head jamb—the highest part of the frame you'll be able to see.
You can replace individual sliding glass doors if the manufacturer still makes a comparable panel, or with the help of a custom door installer. You can also replace the glass in a sliding door without replacing the door or the full frame.
