Crochet patterns look like encrypted messages the first time you see one. Rows of abbreviations, numbers in parentheses, asterisks indicating repeats, and a general tone that assumes you already know what everything means. The truth is that pattern language follows a consistent logic, and once you crack the code, every pattern becomes readable. This guide walks through it step by step.
Crochet patterns use standardised abbreviations to keep instructions compact. Here are the ones that appear in nearly every pattern:
ch = chain. The foundation stitch. A series of loops pulled through each other to create a starting row.
sl st = slip stitch. A flat stitch used to join rounds, move across stitches without adding height, or create a finished edge.
sc = single crochet (US term). The shortest and most common stitch. Insert hook, pull up a loop, yarn over, pull through both loops.
dc = double crochet (US term). Taller stitch. Yarn over before inserting the hook, then work off the loops in pairs.
hdc = half double crochet (US term). Height between single and double crochet.
tr = treble crochet (US term). Taller still. Yarn over twice before inserting the hook.
inc = increase. Work two stitches into one stitch to add width.
dec = decrease. Work two stitches together as one to reduce width.
sk = skip. Miss a stitch and work into the next one.
sp = space. The gap between stitches, usually in lace or openwork patterns.
st(s) = stitch(es).
RS / WS = right side / wrong side. Which face of the fabric is the "front."
Most patterns include a key or abbreviation list at the top. Read it before you start. If a pattern uses an unusual or pattern-specific abbreviation, it will be defined there.
The punctuation in crochet patterns is where most beginners get lost. It serves two different purposes, and knowing which one is being used at any given moment makes everything clearer.
When you see *sc, dc, sc* repeat around, it means: do a single crochet, a double crochet, and another single crochet, then go back to the first asterisk and do the same sequence again. Keep repeating until you reach the end of the row or round. The asterisks are bookends around a sequence that gets repeated.
Some patterns write this as "rep from *" instead of placing a closing asterisk. Same meaning. Go back to the first asterisk and repeat the sequence.
Grouping into one stitch: (2 dc, ch 1, 2 dc) in next st means work all of those stitches into the same single stitch. The parentheses group them together and "in next st" tells you where the group goes. This is common in shell and fan patterns.
Stitch count at the end of a row: Row 3: Sc in each st across. (24) means you should have 24 stitches when the row is complete. The number in parentheses at the end is a check, not an instruction. Count your stitches. If you have 24, you're on track. If you don't, something went wrong in that row and you should go back and find the error before continuing.
Square brackets are used for size variations in garment patterns. A pattern might say: Ch [40, 44, 48, 52]. This means chain 40 for the smallest size, 44 for the next size up, and so on. Before starting a garment pattern, circle or highlight the numbers for your size throughout the entire pattern. It prevents confusion mid-project.
This is the single biggest source of confusion in crochet, and nobody warns you about it until you've already made the mistake. The United States and the United Kingdom use different names for the same stitches, and the names are offset by one. A "double crochet" in US terminology is a "treble crochet" in UK terminology. A "single crochet" in US terminology is a "double crochet" in UK terminology.
Here is the translation table:
The chain and slip stitch are the same in both systems. Everything else is shifted. If you're in the UK following a US pattern (or vice versa), you must convert the stitch names or your project will come out the wrong size and shape.
How to tell which system a pattern uses: most patterns state it at the top. If they don't, look at the abbreviations. If the pattern uses "sc" (single crochet), it's US terminology. UK patterns don't have a "single crochet" because the UK system starts at "double crochet" as the smallest named stitch.
Here is a simple dishcloth pattern with annotations explaining each part:
Ch 26. Make a chain of 26 loops. This is your foundation.
Row 1: Sc in 2nd ch from hook, sc in each ch across. (25) Turn. You skip the first chain (it doesn't count as a stitch), then single crochet into each of the remaining 25 chains. You should have 25 stitches. Turn your work so you can work back across.
Row 2: Ch 1, sc in each st across. (25) Turn. Chain 1 (this is your turning chain and does not count as a stitch), then single crochet into each of the 25 stitches from the previous row. Check: still 25 stitches. Turn.
Rows 3-30: Repeat Row 2. Do the same thing for another 28 rows. The pattern doesn't rewrite the instructions because they're identical to Row 2.
Fasten off. Weave in ends. Cut the yarn, pull the tail through the last loop to secure it, and use a yarn needle to hide the loose ends inside the fabric.
That's a complete dishcloth. Every pattern, no matter how complex, is built from these same elements: a foundation, row-by-row instructions with stitch counts, and finishing instructions.
