What are Standard 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.

You can explore other sizing options below to get a better idea of what works for your space.

Two-Panel Sliding Glass Doors

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 Doors

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

Sliding Glass Door Heights

Once you’ve landed on the right sliding glass door size, 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, 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-sized (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.
