01 / METHOD
How to use this calculator
- Use the same linear unit for marker length and width.
- Enter pattern area in the matching square unit.
- Include every piece represented in the marker.
- Investigate any result above 100% as a unit or data error.
02 / APPLICATION
Useful for
- Comparing marker revisions
- Tracking cutting-room material use
- Estimating offcut area
03 / BOUNDARIES
Assumptions and limitations
What the estimate assumes
- Pattern area is accurate and uses the same base unit.
- The marker boundary is rectangular.
What it does not model
- Utilization does not measure cutting quality, labor, or reusable offcuts.
- Splices, end loss, defects, and lay planning sit outside the marker boundary.
04 / NOTES
Frequently asked questions
What is good marker utilization?
It depends on garment geometry, sizes, fabric constraints, and equipment. Compare like-for-like markers rather than relying on one universal target.
Can utilization exceed 100%?
No. That indicates inconsistent units, dimensions, or pattern-area data.
