Check Curtain Fullness Before Buying Panels
Two panels can cover a window yet hang almost flat. Compare their combined flat width with the track width multiplied by the fullness you want, before ordering another pair.

Research prototype — checkout unavailable. Input is processed locally and a draft is saved automatically in this browser profile when storage is available. Reset to sample clears that draft; Pro history has its own clear button. A state link encodes your inputs in its URL: share only non-sensitive rows. Browser history, clipboard and anyone receiving the link may retain it. Optional AI use below leaves this device; it is not required.
Data note: Everything runs in this browser tab on the drapery fullness register: your window | track width cm | total flat panel width cm stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.
Perspective: Before: The fabric must serve the whole track, including the parts outside the opening. After: the drapery fullness register shows the working beside each named row so the reader can change the assumption and inspect the consequence.

Boundary and sources
Finished-width planning only. This does not specify fittings, cord safety, installation strength or fire performance; follow product instructions and keep cords away from children.
- Method: Required flat width is track width × desired fullness. Report max(0, required minus supplied); at ratio 2 the bedroom needs 300 cm and lacks 60 cm. Surplus at another window cannot cancel this shortage.
- All sample records are invented examples. The app does not fetch measurements, policies, files or personal records.
- Google’s official pricing page, fetched 2026-09-29, lists free-tier access including AI Studio. Optional formatting only; limits and availability can change. Free-tier content may be used to improve products. Never paste private records there.
