How the Curtain Fabric Yardage Calculator works
Total curtain width = window width × fullness (2 means double fullness). Number of fabric widths = total width ÷ fabric width, rounded up. Yardage = widths × (finished length + hem and heading allowance) ÷ 36. Patterned fabric needs extra length to match the repeat, so add one repeat per width. Example: with Window or rod width 60 in, Finished curtain length 84 in, and Fullness 2 x, the result is Fabric needed (yards) = 8; Widths of fabric to cut = 3; Cut length per width (in) = 96.
