Yarn Weight and Needle Size Conversion Chart
I’m providing this Yarn Weight and Needle Size Conversion Chart to help you choose the right needle for your yarn or visa versa. Yarn weights in this chart give an approximation of appropriate needles size.
The exact needle size you choose is based off a variety of factors including:
Your own tension as you knit.
How dense or loose you want your piece to be.
Needle size and yarn weight specified in your pattern.
When in doubt, gauge swatch first! More on gauge swatches and knitting tension can be found here.
