Needle Size and Gauge




UK Needle Size vs US Needle Size

The needle sizes we use in the UK are slightly different to the needle sizes used in the US. So if you’re a UK knitter and you’re using a US pattern, or if you’re a US knitter using a UK pattern, you may find this conversion table helpful:

General Needle Size Recommendations

Below is a table showing the different weights of the yarns we sell and the needle size we recommend you use when knitting in these yarns.
Please remember that this is only a general recommendation, and in order to create a lacier or chunkier look in your knit you may choose a larger needle size. Smaller needles will create a tighter, fuller knit than larger needles. If you’re using a pattern, use the needle size suggested and the right gauge (see below).

Gauge and Tension

The gauge is very important but often ignored. If your end product is something you intend to wear and you don’t get the specified gauge right, your knitwear will not be the right size for you.
Before you start knitting, knit a swatch square in stocking stitch (or the stitch specified on the pattern). This swatch will show if you are knitting with the right tension.
Below are some suggested gauges; please bear in mind that these are SUGGESTED, and can really vary depending on many different aspects such as tension, needle size, stitch etc.

Metres of Yarn Needed

The table below shows how much yarn you may need in metres to knit. We stress that this is not always the case and is only approximate. It is of course dependant on the tension, the gauge, needle size, the knit structure (cabling) the size of the person and the style of the knitting (length of a scarf). But this table might help you estimate how much yarn you will need for you project.
