Fabric Roll Yield at 66% fabric yield target: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop fabric yield target to 66%, then walk the calculation through step by step. Calculate the usable yield from fabric rolls used for mattress covers, borders, and quilting panels, accounting for pattern repeat waste and edge trim.

The inputs for this scenario

  • Usable fabric cut from the roll: 88 linear yards (held at the documented default)
  • Total roll length loaded: 100 linear yards (held at the documented default)
  • Fabric yield target: 66 % (the input this scenario stresses; the baseline uses 92)

Working through the calculation

  • The calculation starts from the formula this tool documents: Fabric yield (%) = usable fabric cut ÷ total roll length × 100.
  • Rate works out to 88 % at these inputs, and this is the headline figure for the scenario.
  • Gap to target works out to -22 points at these inputs.
  • Affected count works out to 88 count at these inputs.
  • Total count works out to 100 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where fabric yield target sits at 92% and the headline result is 88 %, this scenario lands almost exactly on the baseline at 88 %.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to fabric yield target, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It measures usable length only, not panel placement efficiency — a roll can hit yield target yet still waste fabric through poor nesting on width.
