What are Common Sliding Glass Door Sizes?

A standard sliding glass door is 80 inches tall with a width varying from 60 to 72 inches or larger, depending on the space. In most homes, doorframes are measured to a standard size to make door replacements easy.
Sliding glass doors typically consist of two sections — 1) a fixed glass panel and 2) a sliding glass panel — though, three-panel doors are also available.

Two-Panel Sliding Glass Door Sizes
Standard two-panel sliding glass doors are 80 inches tall and come in varying widths. The width of the door listed below refers to the entire width of the unit, not just the part you walk through. The actual door opening will be slightly less than half the width of the door.
Common widths for two-panel sliding glass doors are:
- 60 inches, or 5 feet
- 72 inches, or 6 feet
- 96 inches, or 8 feet
Three-Panel Sliding Glass Door Sizes
Three-panel sliding glass doors are understandably much larger than two-panel sliding glass doors.
Standard widths for three-panel sliding glass doors are:
- 108 inches, or 9 feet
- 144 inches, or 12 feet
Four-Panel Sliding Glass Door Sizes
Standard four-panel sliding glass doors typically measure 144 or 192 inches wide and range from 80 to 96 inches in height. They offer a larger opening ideal for showcasing a a patio or deck. Like the three-panel design, the two center panels are usually fixed, with the outer panels sliding to create the entryway.
Sliding Glass Door Heights

Once you’ve landed on the right standard dimensions for sliding glass doors, it’s important to consider height. The last thing you want is a door that doesn’t fit in your room.
Outside of the 80 inch standard height for sliding glass doors, there are two other common sliding glass door height options:
- 82 inches, or 6 feet 10 inches
- 96 inches, or 8 feet
Sliding Glass Door Size vs. Cost
The total cost of a sliding glass door will vary based on several key factors:
- Size (larger sizes are typically more expensive)
- Materials (what the door and frame are made of)
- Upgrades (textured, patterned or colored glass, and non-standard hardware)
Remember, the framing material and hardware can play a significant role in the cost of the door. In general, a standard sliding door size (80-in x 60-in) two-panel sliding glass door will be the most affordable option.
However, it’s important to remember that a sliding glass door is an investment. If you have any desire to add a larger or custom-built sliding glass door to your home, it’s better to do so now than to replace it in a couple years to avoid extra repairs.

More to Know About Common Sliding Glass Door Sizes and Dimensions
There’s a lot more to know about sliding glass door sizes and dimensions. Read on for some of the most popular FAQ on the topic. If you have more questions, our team is always happy to assist.
Can sliding glass doors be custom-sized?
Yes, while there are standard sizes available, sliding glass doors can also be custom-made to fit your unique design requirement or space. Glass Doctor makes this easy!
How do I determine what size sliding glass door I need?
Measure the opening where the door will be installed, considering both the width and height. The number of panels and your available wall space will influence your best option.
Do more panels mean a wider sliding door?
Yes, adding more panels increases the overall width and is a way to bring in more light and create a larger opening to the outdoors.
How do I measure a sliding glass door?
It’s easy to measure a sliding glass door. We recommend following these steps:
- Measure the width: Start outside the glass door, measure horizontally across the door frame. Extend your tape measure from one side of the outer frame (brick, siding, or stucco) to the other. Take measurements at the top, middle, and bottom, and record the smallest value to ensure accuracy.
- Measure the height: Still outside, measure vertically from the bottom of the door sill to the top of the door frame or exterior wall material. Take measurements at multiple points (left, center, and right) and note the smallest measurement.
- Double-check inside measurements (optional): To be thorough, repeat width and height measurements inside the home, measuring the interior frame edges.
- Additional notes:
- Take note of any trim or molding that may affect replacement door fit.
- For multi-panel doors, measure each panel if necessary.
- Accurate measurements are essential for ordering the correct door size and avoiding installation issues.
This method ensures precise dimensions of a standard sliding glass door for replacement or new sliding glass doors and is suitable for most sliding and French patio door styles.
