SAMPLING, FIT AND SIZE APPROVAL

Knitwear Size Set and Grading Before Bulk Production

A base-size approval is the starting point for grading, not approval of every size. Review what changes across the range before the product moves into production preparation.

Direct answer

A base-size sample proves one size within its approved scope. Grading creates new length, circumference, proportion, trim-position and fit relationships across the range. Review the graded measurements first, then use jump-size or physical size-set samples where numbers alone cannot support the decision.

APPROVAL BOUNDARY

Separate what the base size proved from what grading reopens.

Base size approved

The named sample can close specific questions.

  • Measurements on the identified size
  • Fit and balance on the reviewed body
  • Construction and trim positions on that sample
  • The material and finish actually reviewed
Full range still open

Other sizes create new relationships.

  • Length and circumference increments
  • Proportion across the intended size range
  • Neck, armhole, opening and rib relationships
  • Label, pocket, button and trim placement

SIZE-RANGE MAP

Grading changes more than the number printed on the label.

Each size is connected to the same product, but the increments do not affect every dimension or construction point in the same way.

XSReview the lower-range proportion
SCheck the step into the base block
MBase sizeApproved sample reference
LReview added length and circumference
XLCheck balance, openings and trim scale
01

Measurements

Body length, sleeve length and circumferences need intended increments and one agreed measuring method.

02

Construction

Armholes, necklines, ribs, openings and shaped areas may need different rules from straight measurements.

03

Appearance

Pockets, labels, buttons and visible details can look misplaced when their scale or position does not follow the garment.

CHOOSE THE VALIDATION PATH

Use the smallest review path that can answer the size risk.

01

Always begin here

Review the graded measurement chart

Check arithmetic, increments, measuring points, tolerances and the intended change from one size to the next.

Suitable for: every project
02

Target one risk

Make a jump-size sample

Choose a distant size when the wider range creates proportion, balance, opening or trim-placement questions.

Suitable for: focused high-risk checks
03

Compare size groups

Build a partial size set

Review representative small, middle and large sizes when the complete range can be divided into meaningful groups.

Suitable for: broad ranges with clear groups
04

Review every physical size

Build the full size set

Use all sizes when the fit, construction, target market or consequence of a wrong assumption requires complete physical validation.

Suitable for: highest fit or release risk

DECISION VARIABLES

The wider or less stable the product system, the stronger the physical review should be.

VariableLower physical-review needStronger physical-review need
Size rangeNarrow range with familiar incrementsWide range or distinct small and large size groups
SilhouetteRelaxed repeat block with stable proportionsFitted, shaped, cropped, longline or strongly proportioned style
Material responseKnown yarn, wash and recovery behaviourNew yarn, finish, stretch, recovery or dimensional response
ConstructionSimple straight relationshipsShaped shoulders, complex armholes, openings, ribs or engineered structures
Brand detailsFlexible trim positions with generous spaceFixed labels, pockets, buttons, metal trims or graphics sensitive to garment scale

BOUNDED PROCESS EVIDENCE

The recorded cases show separate approval steps, not a completed production result.

CASE 03Process record

An approved S-size sample became the base size.

The record states that the current sample had passed, was defined as size S, and still required a separate grading review.

Boundary: the other sizes and bulk-production status were not confirmed.

CASE 04Partial closure

Passed grading did not close the large-size and label questions.

The recorded plan kept the small-size sample, added a large-size sample, and placed the full labels on both for review. Grading and one metal-label position had passed.

Boundary: completion of the large-size sample, main label, size label, shipment and final approval remained unconfirmed.

SIZE-RANGE RELEASE RECORD

Keep the approved range and the remaining exceptions in one record.

Style / version Base size Target range Fit model / review condition Named approver Decision date
Approved for the range
  • Final graded measurement chart
  • Measuring method and tolerances
  • Sizes physically reviewed
  • Named fit and construction decisions
  • Approved trim and label positions
Still open before production freeze
  • Unreviewed physical sizes
  • Material, wash or recovery changes
  • Unconfirmed labels or trims
  • Exceptions to the graded rules
  • Any later change that reopens fit

Release rule: passing the grading chart does not approve labels, trims or the complete production file. A later yarn, wash, construction or base-block change can reopen earlier size decisions.

CONNECTED DECISIONS

Move from the current size question, not from a generic production checklist.
