Mixed stock cut lists — usable stock length scenarios.
How does changing usable stock length affect mixed stock cut lists when the other inputs stay fixed?
What this decision changes
Full required pieces must fit usable stock. Aggregate area or length alone cannot prove a feasible cut or roll allocation. Method basis: Cuts are sorted longest first and placed into the first stock with room. This gives a reproducible practical allocation, not a proof of the minimum possible number of stock lengths.
The focus is usable stock length. All other shared inputs remain fixed for each evaluated range.
Evaluate your supplied alternatives
Start with your measured plan and selected product data. The initial values and range are illustrative. Each scenario changes only usable stock length; the other entered values stay fixed.

Read the evaluated results
Look for jumps in purchased stock and rejected fits. The rows show actual evaluated allocations, not an assumption that every intermediate size will behave identically.
- Replace every illustrative baseline measurement and selected product value with the inputs for your actual task.
- Enter a comparison range on the focused input's stated unit and quantity basis.
- Review rejected combinations and use the exact detail lines to distinguish measured demand from whole purchases.
- Open an evaluated scenario in the full calculator to save its original inputs and quantity breakdown to a browser material project.
Keep the comparison within scope
Permitted orientation, complete-run requirements and reserved cut losses remain supplied inputs; sampled layouts do not promise a globally optimal cut plan.

Only the listed samples are evaluated. Intermediate values, alternate constraints and global cutting optimality are not inferred from the graph.
