STOCK FIT

Carpet roll length — available roll width scenarios.

How does changing available roll width affect carpet roll length 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: Each room is divided into full-width strips in the direction you choose. Pattern rounding and extra cut length apply to every strip. Different rooms can have different directions.

The focus is available roll width. All other shared inputs remain fixed for each evaluated range.

Roll length = Σ(strips × pattern-rounded cut length) × allowanceCarpet Roll Length Calculator

Evaluate your supplied alternatives

Start with your measured plan and selected product data. The initial values and range are illustrative. Each scenario changes only available roll width; 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.

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.

Uses supplied geometry, product properties and purchasing specifications.

Does not choose or certify construction dimensions, spacing, loads or regulatory requirements.

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