What Is Horizontal Blinds Stack Height?
The stack height of blinds refers to the vertical space taken up by the slats and headrail when the blinds are pulled up. A smaller stack height allows more outside view, while a larger stack height covers more of the window even when raised.
What Affects Blinds Stack Height?
- Slat Size: Narrower slats (such as 1") stack more tightly than wider slats (2" or more).
- Blind Material: Faux wood blinds tend to have a slightly thicker stack compared to real wood or aluminum blinds.
- Window Height: Taller blinds with more slats naturally create a larger stack.
- Headrail Design: Upgraded headrails can minimize stack height and improve function.
Why Does Stack Height Matter?
Choosing blinds with the right stack height ensures you maximize natural light, preserve your view, and maintain a clean look when blinds are raised. This is especially important for smaller windows where stack height could block a large portion of the glass.
