Curtain Tools
Free calculators from the workroom — the same math we run before cutting fabric. Each one turns a measuring question into ordering numbers, and hands them straight to the product configurator when you're ready.
Curtain Size Calculator
Enter your rod width and height, choose fullness and panel count — get exact panel widths, total fabric, and the finished drop.
Open the toolStack Back Calculator
Find how wide the rod should be — and how far past the frame — so fully open curtains stack on the wall, not on your glass.
