How to use this tool
- Enter target width, pattern stitches per 10 cm, pattern stitch multiple, and extra foundation chains in the displayed units.
- Calculate and use each labeled result for crochet foundation repeat fit. Compare the result with a measured sample before committing materials.
Try this example
{
"width": 100,
"gauge": 18,
"multiple": 6,
"extra": 3
}Accuracy and scope
Use gauge measured in the actual stitch pattern; extra chains are pattern-specific and do not contribute to the calculated worked width.
