Sweater Types by Gauge: Complete 3GG–18GG Technical Guide for Knitwear Manufacturing

What Gauge Means in Knitwear Manufacturing

Gauge (GG) refers to the number of needles per inch on a flat knitting machine.

• Low gauge (3GG–5GG) → thick, chunky, heavy

• Mid gauge (7GG–10GG) → balanced, structured, commercial

• High gauge (12GG–18GG) → fine, lightweight, premium

Gauge determines:

• Yarn thickness

• Fabric density

• Breathability

• Machine speed

• Yarn consumption

• Stitch clarity

Gauge also dictates the type of stitches that are possible (e.g., fine-gauge cable knitting is much more technical than bulky cable).

How Gauge Influences Yarn Selection

Low Gauge (3GG–7GG)

Best with:

• Chunky wool blends

• Acrylic blends

• High-bulk yarn

• Textured stitches

Mid Gauge (7GG–10GG)

• Wool blends

• Viscose blends

Fine Gauge (12GG–18GG)

Best with:

• Extra-fine merino

• Tencel/modal

• Silk blends

• Cashmere blends

• High-twist viscose/nylon

Cost Implications Based on Gauge

Chunky Gauges (3GG–5GG)

• Highest yarn usage

• Slowest knitting speed

• Highest production cost

Mid Gauges (7GG–10GG)

• Good yarn efficiency

• Balanced speed

• Most cost-effective

Fine Gauges (12GG–18GG)

• Slow knitting speed

• Higher cost due to fine yarn

• Premium price positioning

Brands must match gauge with pricing tier.

OEM/ODM Workflow for Gauge-Specific Knitwear

Design Interpretation

Factory analyzes:

• Intended silhouette

• Yarn selection

• GSM target

• Stitch structures

Sampling

• Tension tests

• Shrinkage tests

• Gauge calibration

• Fit sampling

Sampling time: 2–5 days depending on gauge.

Bulk Production

• Machine setting consistency

• Yarn lot matching

• MES monitoring

• Tension stabilization

Finishing & QC

• Steam blocking

• Dimensional accuracy

• Clean linking

• Pilling/shrinkage testing

Gauge heavily influences QC tolerance.
