How this curtain width calculator works

- Desired fullness. Enter the value in ×.
- Number of panels. Enter the value that applies to your situation.

What to do with the number
Fullness around 1.5× looks relatively tailored; 2× to 2.5× creates a fuller gathered appearance. Use rod width rather than glass width when curtains extend beyond the window frame.
