How curtain fullness changes the look.

Common fullness choices

• 1.5x: cleaner and flatter, good for small rooms or budget projects.
• 2x: a balanced default for bedrooms and living rooms.
• 2.5x: fuller folds, heavier drape, and more fabric cost.

Rod width should usually extend beyond the window so curtains can stack outside the glass and let in more light.

Measure before buying

Measure the window width, add side returns, multiply by fullness, then divide by the panel width. Round up to a whole panel count.
