This curtain fabric reference table shows the fabric needed for a range of window/track width values, assuming a fullness ratio of 2, a fabric roll width of 1.4 m and a finished drop (incl. hems) of 2.5 m. Every figure is computed with the same engine that powers our Curtain Fabric Calculator, so the numbers are exact.
