A usable size chart must state whether values are body or finished garment measurements and show exactly where and how each point is taken.
Frame the decision
Issue diagrams, base-size values, grade increments, tolerances and layer assumptions, then approve a physical size set against the same document.
Pattern, inspection and buyer teams should reproduce the same measurement from the chart without verbal interpretation.
Build the controlled worksheet
Keep these five topic-specific inputs together so the quotation, sample and inspection teams do not work from different assumptions:
- Measurement names: state the requirement, reference, status and approval owner.
- Point-of-measure diagrams: state the requirement, reference, status and approval owner.
- Finished garment or body basis: state the requirement, reference, status and approval owner.
- Tolerances: state the requirement, reference, status and approval owner.
- Base size and grade rules: state the requirement, reference, status and approval owner.
Evidence to request
- Approved source or drawing for measurement names
- Order-specific record covering point-of-measure diagrams
- Written acceptance basis for finished garment or body basis
- Controlled decision history for tolerances
- Release evidence connected to base size and grade rules
Evidence must identify the relevant product, material, revision or lot. Record any limitation, substitution or item still awaiting approval.
Risks to close before approval
- Using the same measurement name for different points
- Applying tolerances to body dimensions
- Changing grading without recalculating the order ratio
Assign an owner, due date and written disposition to each unresolved risk. Do not allow an informal answer to replace a controlled revision.
Use the result in the RFQ
Attach the worksheet, quantity, destination, required date and current sample status. Ask the supplier to list assumptions and exceptions against the same five inputs.
