How Many Curtain Panels Do You Need For A Sliding Glass Door?

How Many Curtain Panels are Required?

Most probably, you will need two curtain panels for your glass door. The standard glass door is somewhere between 60 to 72 inches which means that the curtain rods have a center post to hold up the panels.

This is also usually a requirement for rods that are much longer than 60 inches. Since the curtain won’t be able to slide between the center posts, one panel should be covering every side.

Some people fancy using traverse curtains which are free of the center post. In such curtains, you can always move one panel on one side whenever you please.

On the other hand, some people like four panels more because they can easily be arranged to keep the sunlight out throughout the day.

But if you are going for the four-panel curtain, you must bear in mind that if the glass door is frequently used, it can be unwieldy to move that many panels every time the door is used.

What Should be the size of the Curtains You Need for a Sliding Glass Door?

Once you have decided on the number of panels you want to put up, there is more thing you need to think about. It would help if you thought about how full you would wish your curtains to look.

You can either cover the door completely or you can get a panel that is twice as much in size as you need. This makes the drapes of the curtain look plush, but it can also be cumbersome to deal with the additional material at the same time.

If this glass door is one of those that are frequently used, keep the curtain simple to avoid the hassle.

Now, all that is left is measuring the door, and then you will know the exact size of the panel needed for your glass door.

What are the Steps to Measure a Sliding Glass Door for Curtains?

The first thing that needs to be measured is the height of the door. If the curtain rod is there, measure the vertical height because that will tell you the distance between the floor and where the curtains will hang.

If the rod is not installed, you need to add four inches to the height because the height of a standard door is 80 inches and adding the extra space for the rod makes it 84 inches.

After the height, you will then measure the width of the floor. The usual width of the glass sliding doors is five to six feet wide. More often, it is six feet. This makes it a width of 60 inches or typically 72 inches.

An additional 4 inches is added here to leave an overhang so that you can conveniently push the curtain back from the doorway. For a six-foot door, this makes it a width of 80 inches.

Simple mathematic calculations

  • 80 inches width is divided by two panels with a regular fullness = every panel’s width is 40 inches wide and 84 inches length.
  • 80 inches width is divided by four panels with a regular fullness = every panel’s width is 20 inches wide and 84 inches length.
  • If there is twice the fullness for two panels, then make each panel 80 inches in width and 84 inches in length.
  • If there is double fullness with four panels, use 40 inches-wide and 84 inches long panels.
