How is fit and size grading handled before bulk production?

Direct answer

Grading converts the approved base size into the full range by applying measured increments to each point of measure. Before bulk, VANRD issues a size set (usually the smallest, base and largest sizes) and a measurement sheet with tolerances; the set is measured again after a wash cycle when the fabric shrinks. Bulk is then inspected against that sheet, not against the base sample alone.

What grading actually changes

Chest, body length, shoulder, sleeve, hem and neck opening each move by their own increment. A hoodie may grade 5 cm across the chest per size but only 2 cm in body length — the increments are not uniform, and they must follow the fit intent.

This is why a base-size sample alone cannot prove a range. A size L that fits does not guarantee an XL that still looks oversized rather than simply bigger.

Checkpoint	What to confirm	When
Base size sample	Silhouette, fabric hand, details	Sampling
Grading rules	Increments per point of measure	Before size set
Size set	Smallest, base, largest	Before bulk
Tolerances	Acceptable deviation per point	With size set
Post-wash measurement	Shrinkage applied to grading	Before bulk approval

Where size complaints come from

Two causes dominate: grading increments copied from a different fit block, and shrinkage applied to the base size but not to the grade. Both show up as “the larger sizes are off” rather than “everything is off”.

Specify tolerances in the tech pack. Without them, measurement disputes have no reference.

Field example

A brand's XL measured 2 cm short against the size set. The cause was shrinkage applied to the base size only, so the increment carried the error upward. VANRD recalculated grading on post-wash measurements, and the resubmitted set passed on the first inspection.

Numbers that matter

Grading uses a separate increment per point of measure, not a single scale factor
Approve a size set, not only the base size
Apply shrinkage to the grade, not only to the base size
Put measurement tolerances in the tech pack before bulk
