Curtain & window treatment fabric calculators

Window treatments are the branch where a fullness ratio and pattern-repeat matching change the number the most — skip either one and you'll come up short. Pick unlined curtains, lined drapery (which also totals lining yardage), or a flat roman shade panel.
