US vs UK crochet terms: match the stitch, not the name

Only stitch names and their abbreviations change. A pattern that does not say which terms it uses needs a check first: see “Resolve an unlabeled pattern” below.

When a pattern doesn’t say US or UK

Look for a US/UK statement, a stitch glossary or an explicit stitch demonstration. The word “double crochet” alone is not enough. A photograph of the finished object is not reliable proof of the terminology.

A US double crochet begins with a yarn over and ends with two successive pull-throughs of two loops. A UK double crochet uses the single-crochet motion taught on this site. Compare the action when the label is unclear.

Keep a translation consistent

Translate every named basic stitch in a repeat, not only the title. Numbers, insertion points and chain spaces remain as written unless the pattern provides different regional instructions.

Gauge and tension can name the same measurement. Fiber spelling and hook labels may change too; use millimeters for the hook and the actual measured dimensions for gauge.
