Consumption formula
Fabric length per garment from the marker length, the number of garments in the marker and an end loss allowance.
Consumption per garment = marker length / garments in marker × (1 + allowance / 100)
| Symbol | Meaning | Unit |
|---|---|---|
| L_m | Marker length | m or yd |
| n | Garments in the marker | pcs |
| a | End loss and other allowances | % |
Use it once the CAD marker is made. It is the basis of the fabric booking for woven orders.
A shirt marker is 6.20 m long with 4 garments. The factory adds 3% for end loss.
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.
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.
