This category is for planning knitting and crochet projects, with a focus on yarn quantities, gauge, stitch counts and sizing. The aim is to make the arithmetic around a pattern easier to follow while keeping your own measurements central to the result.
Begin with your swatch
Record stitches and rows over a measured area, using the yarn, stitch pattern and needle or hook intended for the project. Keep your target dimensions and the pattern gauge alongside those measurements. A yarn substitution should consider length as well as ball weight; equal-weight balls do not necessarily contain equal lengths of yarn.
Planned tools include gauge adjustments, evenly spaced increases and decreases, yarn substitution and blanket quantities. Our general calculators provide existing measuring and conversion tools while this collection is being developed.
