Sock-Knitting Calculators & Tools
Free, practical tools for gauge, yardage, and fit — check your gauge, estimate yardage, pick a needle size, size a sock to a foot, cast on for any circular project, and keep track of rows as you go.
Gauge & Stitch Calculator
Turn a swatch's stitch and row count into stitches and rows per inch, then scale that gauge up to any target width or length. Also checks how far your gauge sits from a pattern's stated gauge, in either direction.
Sock Yarn Yardage Estimator
Estimate the yardage a pair of socks will take from your foot circumference, leg and foot length, and stitch/row gauge, converted through an approximate stitches-per-yard rate for your yarn weight, with a waste buffer built in.
Needle Size Guide & Converter
Convert a US needle size to millimetres or find the nearest US size for an arbitrary mm measurement, and look up the conventional needle range for lace through bulky-weight yarn.
Sock Size to Stitch Count Calculator
Convert a measured foot circumference and your stitch gauge into a cast-on count, with the standard sock negative ease applied and optional rounding to a stitch-pattern multiple.
Cast-On Count Calculator
A general-purpose cast-on calculator for any circular project — hat, mitten cuff, cowl, or sweater — with sensible ease defaults per garment and rounding to your stitch-pattern repeat.
Row Counter
Track a row count against a repeat length and a target total: repeats completed, position in the current repeat, rows remaining, and percent complete.
