WHAT IS A GAUGE IN KNITTING？

The gauge of knitting sweaters is usually indicated by “G,” which refers to the number of needle holes per inch of fabric, either vertically or horizontally. It directly affects the density, fineness, and warmth of the sweater.

— A higher number indicates finer needles; that is, more needles per inch, resulting in a denser knit. This also results in a smoother and finer feel. High-density sweaters are less likely to pill and lose their shape, making them more comfortable to wear.
— For the same yarn count, a higher gauge indicates a thinner sweater, but this doesn’t necessarily mean reduced warmth. This is because increased density reduces the spaces between fibers, making it less likely for heat to escape. However, for a thicker, warmer sweater, choose a lower gauge and increase the yarn ply count.

Common knitting gauges include 1.5G, 3G, 5G, 7G, 9G, 12G, 14G, 16G, and 18G (both GG and G are gauge symbols). This refers to the number of needles per inch. The higher the gauge, the finer the knit; conversely, the lower the gauge, the coarser the texture. This difference is particularly noticeable around 9-gauge and beyond.

Generally, finer gauges are used for spring and summer collections because they produce thinner fabrics, while coarser gauges are preferred for autumn and winter as they yield thicker, more substantial materials. That said, many designers now use coarse gauges with openwork or perforated techniques to create spring and summer styles. Ultimately, the choice depends on the specific development and design intent.

A common issue designers encounter is during the development of fine stripe patterns. They may reference a fine-gauge design but request it to be executed in a coarse gauge while maintaining the stripe dimensions at a 1:1 ratio, which is often difficult to achieve. To put it simply: take 1.5-gauge and 12-gauge as examples. One revolution of a 1.5-gauge machine produces a fabric width of approximately 1.5 cm, whereas achieving 1.5 cm with a 12-gauge machine may require 7–10 revolutions. If the fine stripe in the design is only 1 cm wide, it would be impossible to execute with a 1.5-gauge machine!

Yarn Count: This is divided into the metric count (Nm) and the English count (Ne).

I hope this helps everyone better identify knit sweaters of different gauge types and understand stitch formations. The gauge examples provided are for reference only; more precise specifications should be determined based on R&D requirements.

Adjustments are necessary when working with different yarns and stitch techniques.
