US and UK crochet patterns can use different names for the same stitch. Check the terminology statement before starting. Stitchvella’s original patterns use US crochet terms.
Quick conversion
- US slip stitch = UK slip stitch.
- US single crochet (sc) = UK double crochet (dc).
- US half double crochet (hdc) = UK half treble crochet (htr).
- US double crochet (dc) = UK treble crochet (tr).
- US treble crochet (tr) = UK double treble crochet (dtr).
Why does the difference matter?
If you read a US double crochet instruction as a UK double crochet, you make a shorter stitch than the designer intended. That changes the fabric and can change the size. Translating only a few rows creates inconsistent results.
How can I tell which system a pattern uses?
Look for an explicit “US terms” or “UK terms” statement and the abbreviation key. US single crochet and UK half treble are useful clues, but an unclear pattern is worth checking with its designer. Do not rely on spelling or the designer’s location alone.
Do I need to convert hook sizes too?
Stitch names and hook labels are separate issues. Prefer the hook diameter in millimetres when comparing tools. Use the yarn and gauge specified in the pattern; converting stitch terminology does not mean changing the yarn.
How do I follow a US pattern if I learned UK terms?
- Write the terminology system at the top of your project notes.
- Make a small personal conversion key for the stitches used.
- Practice a swatch in the intended stitches.
- Check both stitch and row gauge.
- Keep the same system throughout the project.
Always follow the designer’s special-stitch definitions. A custom stitch abbreviation may not follow a general conversion chart.
