Curtains for Sliding Glass Doors: Types

Curtains or Drapes

Curtain panels and drapes are the most common window treatments for sliding glass doors. Curtains and drapes on sliding glass doors should be wide enough to close in the middle and easy to open and close.

Curtains or drapes for sliding glass doors work in many weights depending on how much privacy you need, ranging from sheer curtains to blackout curtains.


A valance is a good choice for your sliding door if you live in a private area and/or if you don’t need privacy in a certain room.

These curtains hang down from the top of the doors and cover just the top. You can use a valance in combination with other window treatments like shades.


There are many shade options for sliding glass doors. You can use Roman shades mounted above the sliding glass doors or choose vertical blinds or sliding shutter panels.

How to Measure Curtains for Sliding Glass Doors

  1. First, decide how much area you want to cover with your curtains.  
  2. Next, measure the width of the total area and then multiply that number by 2 or 3 depending on how full you want your curtains. Then, divide that number by 2 in order to give you a number for both sides of the door frame. 

For example, if I measure my total width and come up with the number 100 inches, I would multiply this times 3 to get 300 inches. I would next divide this by 2 to get 150 inches for each side. This way, I can determine how many panels I need for each side.

  1. Measure the line from where you will mount your curtain hangers/rod down to about 1/2 inch above the floor. This number will be the length of your curtain panels.
  2. For a more custom look, buy curtains that you can mount at least 4-6 inches above the door frame if your wall allows.

Frequently Asked Questions (FAQ)FAQ

Can you put curtains on sliding glass doors?

If you decide that you want to cover more of the area beside the door like the windows or wall beside them, include the additional width into your calculation.

Why is my sliding glass door so drafty?
