What is Stack Back?
Stack Back Width
- Refers to the drape width that stacks at each edge when fully open.
- Minimizing the stack back width allows your curtains to sit aside and barely touch the windows or sliding doors. It makes for max light and view.
Stack Back Depth
- Referring to the drape depth that curtains stack back when fully open.
- Leaving enough space with the stack back depth in mind ensures a crisp look for your curtains to flush in with any hardware, including rod and cornice box.
How to Calculate Stack Back?
Below are the stacking ratios for different curtain head styles:
| Header Style | Grommet | Rod Pocket | Pinch Pleat / Euro Pleat | Back Tab / Tab Top | Flat Panel | Ripple Fold |
|---|---|---|---|---|---|---|
| Stack Back Width/ Coverage Width | 8-15% | 12-20% | 20-25% | 20% | 15-20% | 25-30% |
| Stack Back Depth | 6 1/2 IN | 2-3 IN | 3 1/2 IN | 3-4 IN | 4-5 IN | 4 1/2 IN |
Additional Notes
- Sheer curtains have a minimal stack back width. The thicker the fabrics, the larger the stack backs.
- The stack back size is calculated in a rough manner, it may vary along with fabrics, add-on linings, puddling, curtain rods, brackets, and even rings.
