Knitting Needle Substitution
Many patterns use more than 1 knitting needle size but only give tension for the main knitting needle size e.g. a smaller size will be used for ribbing. If you've had to change the needle size to get the correct tension how can you estimate the other needle size? Simply fill in the details below and our knitting needle size calculator will calculate the best needle size to try. You will need to supply the needle sizes in mm.

Knitting Yarn Calculator
If you are planning to substitute the pattern's recommended yarn you'll need to calculate how many balls of substitute yarn you will need. You'll need to know the amount of yarn in each ball of the recommended yarn and your substitute yarn. If you can't find the information you need from the pattern or ball bands then yarndex.com is a useful site for finding this information.
