Procurement decisions and comparisons
Fabric by Weight vs Length: Reconcile the Purchasing Basis
Fabric bought by weight and fabric bought by length use different quantity bases. A meaningful comparison needs the identified material, width, mass basis and treatment of usable quantity. Do not convert a quoted kilogram amount into garment yield using a guessed fabric weight or an unverified roll width.
For buyers checking nominated-fabric offers against garment material plans.
Keep the commercial unit beside the material identity
Record the supplier material reference, finish state and quoted unit exactly as offered. Ask whether the weight is net fabric or includes packaging and whether the length is measured under an agreed handling condition. Record nominal width separately from the width considered usable. A price per unit cannot be compared fairly when one offer includes a different width, finish or allowance. Preserve the original units in the comparison instead of hiding them behind a single estimated garment cost.
Build a conversion only from compatible measured inputs
If a planning conversion is necessary, request material mass per area and the corresponding width in consistent units. Ask who measured them, on which sample or roll and at what stage. A calculated relationship between area, width and mass is only as useful as those inputs. Label it as a planning estimate rather than an inventory receipt. Roll variation, unusable edges and cutting loss need their own evidence and should not be invented as a universal percentage.
Separate purchasing quantity from cutting consumption
Ask how the maker will reconcile purchased fabric, accepted rolls, cutting allocation and remaining material. A commercial fabric unit does not determine how many garments a marker will yield. Use an agreed marker or cutting plan for that separate question, with the intended size mix and material direction restrictions. If actual receipts differ from the estimate, record the measured basis before revising the plan. This prevents an apparent lower unit price from concealing a different usable quantity or material specification.
Decision and evidence checklist
| Decision | Include in the brief | Review evidence |
|---|---|---|
| Quoted quantity | Original unit and net/gross basis | Supplier quantity statement |
| Planning conversion | Width and mass inputs | Identified measurement record |
| Garment consumption | Size mix and cutting restrictions | Agreed material-use plan |
What this brief does and does not establish
This is a unit-reconciliation workflow. No fabric price, roll tolerance, cutting yield or MyOwnWear procurement practice is asserted; all measured inputs need project evidence.
Share the two fabric offers with their original units and material references; ask MyOwnWear to identify missing inputs before comparing garment material plans. Open the MyOwnWear RFQ form.
Buyer questions
Is fabric sold by weight necessarily knitted?
Do not infer construction from the commercial unit. Confirm the material identity.
Can nominal width establish usable fabric area?
Not alone. Confirm the agreed usable width and any excluded edges.
Does a unit conversion prove garment yield?
No. Garment yield depends on the actual cutting plan and accepted material.
