Production calculator
Calculate marker efficiency and fabric waste from the total pattern area in the marker and the marker length and width, in centimeters or inches.
Marker efficiency
82.67%
Marker efficiency % = pattern area / (marker length × marker width) × 100
| Symbol | Meaning | Unit |
|---|---|---|
| A_p | Total area of pattern pieces in the marker | cm² |
| L_m, W_m | Marker length and width | cm |
Marker area = marker length × marker width. Marker efficiency = total pattern area / marker area × 100. Waste is the rest. Results are shown as percentages and as areas in square meters.
See marker making for how to improve markers.
Defaults: pattern area 62,000 cm², marker 500 cm long and 150 cm wide.
Use the marker width that matches the cuttable width of the fabric you will actually cut. Try different size combinations in CAD: mixing large and small sizes often raises efficiency. Track efficiency by style type so you know what is achievable. See reducing fabric waste in cutting.
From the CAD system, which reports the area of all pieces in the marker. For manual markers, calculate or measure the area of each piece.
It depends on the product, pattern shapes, sizes combined and fabric width. Compare with previous markers for similar styles rather than a single general figure.
The marker decides how much fabric an order uses. How markers are planned, what limits efficiency (grain, direction, matching, width), how to calculate marker efficiency, and how to improve it without hurting quality.
Fabric is the largest cost in most garments, and the cutting room decides how much of it becomes garments. Where fabric is lost, how to measure it, and practical ways to cut waste through markers, spreading, end loss control and roll planning.
How to calculate fabric consumption for knit garments (by weight, from panel areas and GSM) and woven garments (by length, from the marker), with worked examples, wastage allowances and the mistakes that cause fabric shortages.
A walk through the cutting room from fabric receipt to bundles issued to sewing: inspection, relaxation, planning, spreading, cutting, numbering, fusing and audit, with the controls and measures that keep it accurate.
