STOCK FIT

Wallpaper rolls — roll length scenarios.

How does changing roll length affect wallpaper rolls 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: Required strips round up across each wall. Cut length rounds up to a whole pattern repeat; half-drop mode includes a half-repeat offset before rounding. Equal cut lengths pool together.

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

Wall 1

Wall width

Where to get this value

Measure this dimension in your plan or on site and use the displayed unit. For irregular shapes, divide the geometry into the supported sections.

Wall height

Where to get this value

Measure this dimension in your plan or on site and use the displayed unit. For irregular shapes, divide the geometry into the supported sections.

Baseline: Wallpaper rolls to purchase — 3 rolls. Rejected combinations remain visible below.

Quantity to plot

Each bar is one actual calculated wallpaper rolls to purchase. Horizontal values: roll length in m.

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.
