How wide should curtains be?

To ensure that curtain panels look ample when closed, they should have a combined width that is 2 to 2.5 times the width of the window/rod. That means if you are ordering Grommet style or Rod-pocket style, the total drapery width should be at least 2 times the window/rod widths. 

French pleat and Tailored pleat style panels have 2:1 to 2.2:1 fullness built-in, so if you are ordering French pleated or Tailored pleat heading style, you should order the panels that fit your window(rod) width. They will cover your window with a nice fullness. 

Ripple fold style curtains have 1.6x to 2.4x fullness built-in, you can order Ripple fold style in the ripple fold custom curtains page. Be sure to enter the coverage width (the track/rod width). 

Exceptions: If you’re hanging curtains just to frame a window and don’t intend to shut them, you can round down to 1.5 times the width. 

Stack Back Width

Stack back is the amount of space the curtains occupy when in the fully open position. We made a stack back calculator for your reference:  Click here for the Stack Back Calculator 

How long should curtains be?

There is no right and wrong answer to this question. A rule of thumb is that it is always better to go higher and to go full length, no matter what sizes are your windows. 

Where should curtains tops be?

Tracks look the best when they are mounted directly to the ceiling. They work perfectly with full height curtains. Rods are usually mounted between ceiling and window. If you find it hard to decide where to go. Go with the rule of thirds. 

Where should curtain bottoms be?

  • Floating above the floor. It creates a "breathable" floating look. If you would like to have straight curtains, this is the best option. 
  • Just hitting the floor. It is hard to make right but it creates a custom-made classic and tailored look. 
  • Puddling. Panels extend to the floor by one to three inches. It adds coziness to space. It is the best for those who are seeking European style and romantic feel. Another upside of the choice is that you don't need to worry about precision measurement in length. The downside is it is high maintenance, and if you have pets it might not be your best choice.

Measure from the floor to where you’ll hang the rod, then round up. You can always have the dry cleaner hem them a bit if needed. Custom-made panels are perfect for extra large windows and for tailored looks.

    Hi Gloria, Sorry I just saw your comments and wanted to reply really quick. You can actually see all the lot width for our fabrics here Most of our fabrics are 110 in width. Also since most of our fabrics have no patterns, they can be turned sideways to avoid seam lines. Please let me know if you have any other questions. Have a great day!

    I need 6 separate lined panels of drapes (gathered). You do not give the width of the fabric. I would like each panel to be __ by 140". What is the width of your fabric? If 54" is 1 width of drape what is the size as a finished panel. I have 2 sets of windows that I want a panel on each side and 1 between each set of windows. Help?
