Crochet chart symbols — the full key
Every symbol Stitch Chart Studio can draw, with what it means, its standard abbreviation and its UK equivalent. The symbols below are rendered by the same code the editor draws with, so what you see here is exactly what lands in your exported chart.
How the symbols are put together
The set is not arbitrary. Once you see the logic, most of a chart reads without a key:
- Height means height. A taller symbol is a taller stitch. A slip stitch is a dot, a single crochet is a short cross, and the posts get longer from half double up to treble.
- Slashes count yarn overs, from double crochet up. One slash is a double crochet, two is a treble, three is a double treble. Half double crochet is the exception: one yarn over, but drawn as a plain T, because its loops come off the hook in a single pull.
- A shared foot means a shared stitch. Several posts meeting at one point at the bottom all go into the same stitch or chain space — that is a shell, a fan or a cluster.
- A shared top means stitches worked together. Posts converging into one top bar are a decrease, or a cluster if their feet all sit in one place.
Craft Yarn Council, whose standardized set most designers follow, describe each symbol as showing the stitch as it appears on the right side of the work. That is why symbols in a round chart are rotated to point outward: they are drawn the way the stitch actually leans.

Common questions
What do crochet chart symbols mean?
Each symbol stands for one stitch and is drawn where that stitch goes, so its position tells you what to work into and its height tells you how tall the stitch is. A cross is a single crochet, a plain T is a half double, a T with one slash is a double crochet, and each extra slash is one step taller.
Are crochet chart symbols the same in every pattern?
Nearly. Most designers use the Craft Yarn Council standard set, but details vary — single crochet is drawn as a plus sign by some publishers and an × by others, and specialty stitches such as picots differ more. Every well-made pattern includes its own key, and that key is the authority.
Do chart symbols change between US and UK patterns?
No. The symbols describe the shape of the stitch, not its name, so a T with one slash means the same stitch whether the pattern calls it a double crochet (US) or a treble (UK). That is why a chart is the fastest way to settle which stitch a confusing written pattern really means.
