What Is Stacked Width?
Stacked Width
Refers to the curtain width that gathers at each side when the drapes are fully closed.
In the calculator, the Stacked Width value represents the Fully Stacked Width — the total space your drapery takes up on one side when completely drawn open.
- A smaller stacked width allows more light to enter and minimizes obstruction to your window view.
- A larger stacked width gives a fuller, more luxurious look with a stronger visual presence.
- Thicker fabrics create a larger stacked width.
*Note: The figures above reflect unlined fabric only. Adding lining will increase the stacked width.
