Understanding gauge: what 3GG, 7GG and 12GG mean for your knit

Gauge is one of the most important — and most misunderstood — specs in knitwear. Here's a plain-English guide to choosing the right one.

Gauge (written as GG, for 'gauge') describes how fine or chunky a knit is — specifically the number of needles per inch on the knitting machine. Lower numbers mean chunkier knits; higher numbers mean finer ones.

A quick gauge guide

• 3GG–5GG: Chunky, heavyweight knits — cosy winter sweaters and statement pieces.
• 7GG: A versatile mid-weight — the workhorse gauge for many sweater programs.
• 12GG and finer: Lightweight, smooth fabrics — fine-gauge sweaters, polos and base layers.

Why gauge matters for cost and feel

Gauge influences yarn consumption, knitting time, drape, warmth and price. A chunky 3GG sweater uses more yarn but knits faster per piece; a fine 12GG garment uses less yarn but takes longer to knit and demands more precise finishing.

When you brief a manufacturer, specifying your target gauge alongside yarn and structure helps get an accurate sample and quote quickly. If you're unsure, share a reference garment and we'll match it.
