Crochet size charts are a handy things to have whether you are a beginner or experienced crocheter. In this blog post, I’ll be sharing with you some of the crochet size charts you’ve got to have in your possession. The charts provided here are just a summary.

1. Crochet abbreviations chart
Although not technically a crochet size chart, crochet abbreviations are the back bone of crochet. Whether you’re diving into a new pattern or writing your own, it’s always helpful to have some of the most common crocheting abbreviations handy. Generally, abbreviations are given at the beginning of a book or pattern. However, it’s always good to familiarize yourself with terms used in crochet.
Abbreviation | Meaning | Abbreviation | Meaning |
---|---|---|---|
Yo | Yarn over | Sl st | Slip stitch |
Sk | Skip | Ch | Chain |
MC | Main colour | Tch | Turning chain |
CC | Contrasting colour | Sc | Single crochet |
Rep | Repeat | Hdc | Half double crochet |
RS | Right side | Dc | Double crochet |
WS | Wrong side | Tr | Treble/ triple crochet |
BLO | Back loop only | Dec | Decrease |
FLO | Front loop only | Inc | Increase |
2. Crochet US/ UK conversions chart.
I’ve been crocheting for a really long time. When I started exploring with crochet patterns, imagine my confusion when I realized that US and UK basic stitches, although the same, are called different names. That means there’s one set of basic stitches worldwide but there are two sets of names for them. You will want to know whether a pattern uses US or UK terms before starting it, and having this chart won’t hurt either.
U.S. | U.K. |
---|---|
Slip stitch (sl st) | Slip stitch (ss) |
Single crochet (sc) | Double crochet (dc) |
Half double crochet (hdc) | Half treble crochet (htr) |
Double crochet (dc) | Treble crochet (tr) |
Treble/ triple crochet (tr) | Double treble crochet (dtr) |
Back post double crochet (bpdc) | Raised treble crochet back (rtrb) |
Front post double crochet (fpdc) | Raised treble crochet front (rtrf) |
Skip (sk) | Miss |
Yarn over (yo) | Yarn over hook (yoh) |
Gauge | Tension |

3. Crochet hook conversion chart
Crochet hook sizing is important. However, just like basic crochet stitches, how hook sizes are indicated may vary. Below, I will show you all the US sizes of hooks, and their Metric and UK equivalents in the crochet size hook conversion chart.
