Crochet Abbreviations (US and UK)

Why do crochet patterns use abbreviations?

Written out in full, a pattern would run for pages. Abbreviations keep instructions short and let you scan a row at a glance. A line like "sc in next 5 st, 2 dc in next st" is faster to read than a full paragraph, and once the codes are familiar, your eyes stop translating and just follow along.

Most US patterns list their abbreviations near the top or in a key. When one is missing, a standard reference fills the gap.

What are the most common crochet abbreviations?

Here are the ones you will meet in almost every US pattern:

1. ch: chain
2. st / sts: stitch / stitches
3. sl st: slip stitch
4. sc: single crochet
5. hdc: half double crochet
6. dc: double crochet
7. tr: treble (triple) crochet
8. yo: yarn over
9. sk: skip
10. sp: space
11. rep: repeat
12. rnd: round
13. inc: increase
14. dec: decrease
15. tog: together (as in dc2tog, two stitches worked together)
16. BLO / FLO: back loop only / front loop only

How are US and UK crochet terms different?

Both systems use the same set of words, but they point to different stitches. The names are shifted by one. What the US calls a single crochet, the UK calls a double crochet. This one shift is the number-one source of pattern confusion, so it is worth a careful look before you start.

Here is the key comparison:

1. US single crochet (sc) = UK double crochet (dc)
2. US half double crochet (hdc) = UK half treble crochet (htr)
3. US double crochet (dc) = UK treble crochet (tr)
4. US treble crochet (tr) = UK double treble (dtr)
5. US slip stitch (sl st) = UK slip stitch (ss)

How do I tell if a pattern is US or UK?

A few quick tells will sort it out:

1. Look for a stated key. Many patterns say "US terms" or "UK terms" up front.
2. Check the spelling and words. "Gauge" and "yarn weight in yards" lean US. "Tension" and "double knitting" lean UK.
3. Scan for "sc". Single crochet exists only in US terms. If you see "sc" anywhere, the pattern is almost certainly US.
4. Match the hook sizing. Millimeters plus a letter (5.0 mm / H-8) is common in US patterns.

What do I do once I know the abbreviations?

Read the whole line before you pick up the hook. Find the repeat section, usually marked with an asterisk or brackets, and count how many times it runs. Then work stitch by stitch, checking your count at the end of each row or round.

Counting is where most mistakes hide. Miss one stitch in a repeat and the row comes out short, which throws off every row after it. Say the numbers out loud, or use a row counter to hold your place when you set the work down.

If you keep patterns and counts on your phone, an app like Worsted can count rows for you, store the pattern PDF, and track the yarn in your stash so everything sits in one spot.

What should I remember about crochet abbreviations?

Crochet abbreviations are just shorthand for stitches and actions. Learn the common US codes first: ch, sc, hdc, dc, tr, sl st, and the increase and decrease pairs. Then remember that UK patterns shift every name up by one, so US sc equals UK dc.

Confirm which system you are reading before the first stitch, keep an eye on your counts, and the pattern will read like a clear set of directions.
