Estimate fabric kg per garment from marker length, width, ply and pieces.

Marker length (metres)Fabric width (metres)GSMGarments in marker

Estimated fabric: —

Estimate only; add marker wastage, shrinkage and process allowance separately.

Convert fabric weight between grams per square metre and ounces per square yard.

Weight: —

Calculate line efficiency from earned minutes and available minutes.

Output (pieces)SMV per piece (minutes)ManpowerWorking hours

Efficiency: —

Calculate defect rate from inspected quantity and defective pieces.

Defect rate: —

Compare used marker area with total fabric area.

Marker length (m)Usable width (m)Garment pattern area (m² total)

Utilization: —

Available production time divided by customer demand.

Available minutes / shiftBreak / downtime minutesRequired output (pcs)

Takt time: —

Find the slowest operation and compare with target cycle time.

Target cycle time (seconds)Operation times (seconds, comma separated)

Bottleneck: —

Estimate theoretical hourly output from cycle time and efficiency.

Cycle time (seconds / piece)Efficiency (%)

Output: —

Rough thread estimate from stitch count and thread ratio.

Stitches per garmentThread ratio (thread length / seam length)Allowance / wastage (%)

Thread: —

Planning estimate only; actual consumption varies by stitch type, SPI, fabric and machine.
