Free crochet tools
Small useful things,
built carefully.
Every one of these is free, works without an account, and does the arithmetic the way a careful stitcher would — including telling you when a number is an estimate rather than a fact.
Row counter
Count rows, stitches and pattern repeats — several at once, named, side by side. Keyboard and tap, keeps the screen awake, saves your place on this device. No account.
Gauge calculator
Your swatch against the pattern’s gauge. Recalculates the cast-on for the size the pattern promised, or works stitches back from a finished measurement.
Knitting needle sizes
US, UK and metric side by side, with the yarn weight and gauge each size suits. Sizes with no counterpart are marked, not guessed.
Yarn calculator
How much yarn do I need? Calculate by stitch count, finished dimensions, or yardage estimate. Includes wastage + shrinkage adjustment and skein rounding.
Pattern resizer
Resize a crochet chart by stitch count or finished dimensions. Gauge correction baked in.
US ↔ UK terminology
Translate between US and UK crochet stitch names, hook sizes, and yarn weights.
Image-to-pattern converter
Turn any photo into a crochet, cross-stitch, knit colorwork, pixel art, or fuse-bead chart.
