Converting Yarn Weights

Do you want to use yarn from The Rocking Yak with a pattern you have already picked out? Here is how to choose the right yarn for your project.

The Rocking Yak Yarn Standard Yarn Weights
Knitting Needle size
Bulky Chunky, Craft, Rug 9 – 11 US / 6 – 8 mm
Medium Worsted, Afghan, Aran 7 – 9 US / 4.5 – 5.5 mm
Light Light Worsted, DK 5 – 7 US / 3.75 – 4.75 mm

Another way to double check is to find the weight they ask for in grams and yarns and then find the similar sizing on our labels. For example, if the pattern says 140g is 250yds, take 250yds, divide by 140g and multiply by 100g. (Our standard size balls are 100g). In this example, the length you are looking for in our 100g balls is 178yds. That would be our Fall Medium yarn which is approximately 100g/180yds.

Choose the correct weight of yarn from The Rocking Yak based on name or yardage and then knit a swatch. Change your needle size to get the right gauge. If you have too many rows and stitches, use a smaller needle. If you don’t have enough, try a slightly larger needle. Hand-spun yarn can have some variations so make sure your swatch is somewhat larger than 5 x 5 inches or 12 x 12 cm.
