If you've ever dreamed about peering into your garden from the comfort of your kitchen table, installing sliding glass doors 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.

Standard Sliding Glass Door Sizes

Sliding glass doors range from 60 to 144 inches wide and 80 to 96 inches high. Keep in mind that the width covers the full distance between the outer frames, not the just width of each sliding panel.

Manufacturers stick to standard sizes for doors, windows, and cabinets for good reason. Standard sizes make the replacement process 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 PanelsTypical Door Widths
Two-panel sliding doors60 inches, 72 inches, or 96 inches
Three-panel sliding doors108 inches or 144 inches

Sliding Glass Door Heights

Since the standard ceiling height in a home is between eight 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

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 Replace 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 price, 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.


What is the standard rough opening for a sliding glass door?

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.

How do you measure the size of a sliding glass door?

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.

Can you replace sliding glass doors without replacing the frame?

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 without replacing the door or the full frame.
