SUPPLIED LAYOUT INTERVALS

Straight repeat fabric panel layout — vertical straight repeat scenarios.

How does changing vertical straight repeat affect straight repeat fabric panel layout when the other inputs stay fixed?

What this decision changes

The chosen interval or repeat changes discrete positions, full rows or complete pattern cuts. It is different from a blanket percentage added to area. Method basis: Order matched rectangular fabric panels on a straight repeat grid using usable roll width and two repeat directions. Only straight repeat. It does not infer a textile pattern, choose seam allowance or cover fire-rated fabrics.

The focus is vertical straight repeat. All other shared inputs remain fixed for each evaluated range.

Grid width/drop round up to whole repeats; panels across = floor(usable width / grid width); order = rows × grid drop + initial trim.Straight Repeat Fabric Panel Layout Calculator

Keep the comparison within scope

Compare intervals already permitted by your plan or product. No safe spacing, structural layout or fixing requirement is chosen.

Only straight repeat. It does not infer a textile pattern, choose seam allowance or cover fire-rated fabrics.

Dimensions, allowances, prices, properties and specifications are supplied by you. The tool computes their arithmetic consequences; it does not choose construction specifications or certify suitability.

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