DrapePlan is a practical curtain calculator for makers, workrooms, decorators, and installers who need a clear estimate without opening a spreadsheet.
Enter your finished track width and drop, choose a saved fabric, set fullness, and review fabric quantities, lining, cut lengths, purchase metres, and estimated cost. Everything works offline, so you can calculate at the workbench, on site, or anywhere your job takes you.
