What Is Curtain Stack Back?
Curtain stack back refers to the space your curtains take up on either side of the window when they’re fully open. This measurement is important because it determines how much of the window remains visible—and how much natural light you let in—when the curtains are drawn open.
Stacking Width for Pinch Pleat Curtains
For pinch pleat curtains, the stacking width typically makes up about 20% of the total curtain width you order.
For example, if your curtain width is 100 inches, the stacked fabric will take up around 20 inches of space when fully opened.
If your curtains open from the center, each side will stack back about 10 inches.
What is curtain stacking width, and why does it matter?
Curtain stacking width is the amount of space the curtains take up on each side when fully opened. It affects how much of your window is visible and how much natural light comes in. Knowing the stacking width helps you pick the right curtain size and rod length so your curtains won’t block the window when open.
I ordered pinch pleat curtains that are 100 inches wide. How much stacking width should I expect?
For pinch pleat curtains, stacking width is usually about 20% of the total curtain width. So for 100-inch curtains, expect about 20 inches of stacking when fully opened. If your curtains open in the center, each side will stack about 10 inches.
How do I choose the right curtain rod length based on stacking width?
Your curtain rod should be as wide as your window plus the stacking width on both sides. For example, if your window is 80 inches wide and you have 10 inches of stacking on each side, you’ll need at least a 100-inch rod to make sure your curtains fully open without blocking the window.
