Calculation method
Calculation method
Gross area-equivalent strip length (cm)
W*H/stripWidth.
Loss-adjusted estimated strip length (cm)
(W*H-lossArea)/stripWidth.
Discarded area (cm²)
Explicit user seam/edge loss area.

Assumptions & limits
Assumptions & limits
- Area conservation estimate for a user-chosen continuous bias construction. Does not promise a realizable spiral cutting layout or exact uninterrupted yield; the explicit loss area must come from the chosen pattern or a measured trial. Supported limits: W,H,stripWidth>0; 0<=lossArea<W*H. This is explicitly a yield estimate, not a layout.
