Fabric yield is the practical relationship between fabric weight and the number of garments produced. It is one of the fastest ways to estimate order feasibility, fabric requirement and cost per piece.
Why This Matters
Two polyester fabrics priced at the same rate per kilogram may produce very different piece counts if their GSM, width or garment pattern differs. Yield therefore connects fabric specification directly to commercial cost.
Key Components
- Fabric GSM
- Tubular DIA or open width
- Garment size and pattern area
- Sleeve length and style
- Marker efficiency
- Cutting loss
- Rib and contrast parts
- Size ratio in the order
Practical Method
The most reliable method is to use approved marker consumption. If one T-shirt consumes 0.20 kg of fabric, theoretical yield is 5 pieces per kilogram. In real production, actual yield will be slightly lower after end loss, defects and cutting wastage are included.
Working Example
If an M-size polyester T-shirt uses 0.17 kg and an XL uses 0.21 kg, a mixed-size order cannot use one universal pieces-per-kg value. Calculate the weighted average consumption using the actual size ratio.
What Buyers and Factories Should Check
- Use finished GSM, not greige GSM
- Confirm width after finishing
- Check marker efficiency
- Include size mix
- Separate main fabric and rib consumption
- Compare theoretical and actual yield
Common Mistakes
- Assuming one kg always gives the same number of T-shirts
- Ignoring GSM variation
- Using one size as the whole order average
- Ignoring cutting wastage
- Comparing fabrics only by ₹/kg
Best Practices
- Create a yield chart by garment style
- Use actual bulk marker data
- Track actual pieces produced per roll
- Investigate large differences between planned and actual yield
Final Thoughts
Fabric yield is one of the most useful numbers in polyester garment manufacturing. It translates fabric specification into pieces, cost and order planning.
