Quick answer
How do I calculate fabric requirement for an order?
Fabric requirement = garments to cut × consumption per garment × (1 + wastage%) × (1 + shrinkage%).
Garments to cut = Order qty × (1 + Excess%)
How it works
Fabric Requirement Calculator
Work out exactly how much fabric to book for an order — including excess cut quantity, cutting wastage and shrinkage.
Start from the garments you will actually cut (order plus excess), multiply by net consumption, then add cutting wastage and shrinkage to get the gross fabric to book.
Formula
The formula, in full
- Garments to cut
- Order qty × (1 + Excess%)
- Net fabric
- Garments to cut × Consumption
- Fabric to book
- Net × (1 + Wastage%) × (1 + Shrinkage%)
- Weight
- Metres × Width (m) × GSM ÷ 1000
Example
10,000 pcs with 3% excess
- 01Cut 10,300 pcs
- 02Net = 16,480 m
- 03Book = 16,480 × 1.03 × 1.03 = 17,484 m
Use “Load Example” above to run this example in the calculator.
Industry tip
Industry tip
“Book shrinkage only if your consumption was measured on unwashed patterns. If patterns are already graded for shrinkage, set it to 0%.”
Assumptions
What this calculator assumes
- Wastage and shrinkage are compounded.
- Weight is shown only when width and GSM are entered.
