Curtain Planners
A whole-run planner is not three single-window calculators. It plans one continuous run from your own measurements.

Bay window: live in this test build. It gives whole-run rod length, panel count, panel width, stated fullness, and length style together.
Sliding door: live in this test build. It also gives stack space from the spaces you enter, and a door clearance note, so you can check that the door still slides.
Multi-window wall: live in this test build. It gives one continuous rod length, spacing from the gaps you enter, and gap coverage, not just each window alone.
On live desktop search on 28 Oct 2026, no page 1 result for the curtains terms checked gave a whole-run plan together, and single-window calculators gave only part of a plan. That is the gap these three planners are built to fill, from your own measurements, not a ranking claim.
Measure first: how to measure curtains. Guides that feed the tools: curtain fullness explained, curtain length guide, curtain heading styles, bay window curtain hardware, sliding door curtain stack space and door clearance.
