FAQ
What fullness ratio should I choose?
Common ratios: 1.5× (budget), 2× (standard/aesthetic), 2.5-3× (luxury). Higher ratios create more pleats.
How to calculate curtain height?
Height = Window Height + 20-30cm (rail/pole) + 10-20cm (floor clearance). Adjust based on installation method.
Why is fabric area width × height?
It's an approximation of the cut fabric size. Actual usage depends on fabric width, pattern matching, and seam allowances.
