Why are UK and US Crochet Terms Different?
If you’ve tried your hand at a few different crochet patterns, you may have noticed a sometimes confusing difference between UK and US crochet terms. It can be a frustrating realisation, especially for beginners, as it’s not immediately apparent why these discrepancies exist! In this article, we’ll explore the history and reasons for these differences in crochet terminology.
How do UK and US Crochet Terms Differ?
First, let’s address the primary differences in terminology. While some stitches are the same across UK and US crochet terms, other stitches are referred to differently. This can impact the way patterns are read and followed. For example, what is known as a single crochet stitch in the US is referred to as a double crochet stitch in the UK, and the differences continue with subsequent stitch terms.
Use this conversion chart to translate stitches between UK and US terms when working with patterns from different sources:
| US Terms | UK Terms |
|---|---|
| Single Crochet (sc) | Double Crochet (dc) |
| Double Crochet (dc) | Treble Crochet (tr) |
| Half Double Crochet (hdc) | Half Treble Crochet (htr) |
| Treble Crochet (tr) | Double Treble Crochet (dtr) |
| Double Treble Crochet (dtr) | Triple Treble Crochet (trtr) |
| Front Post Double Crochet (FPdc) | Raised Treble Front (RTrF) |
| Back Post Double Crochet (BPdc) | Raised Treble Back (RTrB) |
Now that we’ve established the key differences, let’s delve into why these distinct crochet terms have evolved.
The History of Crochet
Origins
The exact origins of crochet are unknown. However, some historians believe that crochet dates back to ancient civilisations, such as the Egyptians and Mesopotamians. During these periods, crochet-like techniques were used for decorative purposes, such as embellishments on clothing.
The Growth of Crochet in the UK and the US
Crochet first gained popularity in the UK and the US in the 1800s. In these early years, there were already some variations in patterns and methods used in the UK and the US. This was primarily due to the preferences of local pattern designers and the materials available in each region. As a result, the terminologies for crochet stitches began to diverge in these countries.
The development of crochet techniques was further influenced by regional influences and traditions. For example:
- European crochet predominantly used finer threads and smaller hooks.
- American crochet frequently incorporated thicker yarns and larger hooks.
These variations in materials and techniques led to corresponding differences in the names of crochet stitches. Crochet pattern books began being published independently in both the UK and the US during the 19th and 20th centuries. In the absence of a unified global standard for crochet terminology, the pattern creators developed separate terminologies that catered to their respective markets.
With the advent of the internet in recent decades, the there has been much more sharing and collaboration across the global crochet community. However, despite the growing interconnectivity, the UK and US crochet terminologies have remained distinct.
How to Adapt to Different Crochet Terms
When starting a new pattern, always check whether it is written in UK or US terms before beginning. Many patterns will indicate their origin or include both sets of terms. However, if you’re unsure, ask the designer or publisher. And remember, if ever you spot a single crochet (sc) in a pattern, then you know it’s written in US crochet terms.
With a bit of practice, it doesn’t take long to become proficient at reading patterns in both UK and US terms. However, when you’re starting out, for some crocheters, annotating the pattern with your preferred crochet terms is a helpful step for avoiding errors.
Understanding Hook Sizes
As well as stitch names, hook size terminology also varies between the UK and the US, with each using a different labelling system. A handy conversion chart is provided below:
| US Hook Size | Metric/UK Hook Size |
|---|---|
| B/1 | 2.25 mm |
| C/2 | 2.75 mm |
| D/3 | 3.25 mm |
| E/4 | 3.50 mm |
| F/5 | 3.75 mm |
| G/6 | 4.00 mm |
| 7 | 4.50 mm |
| H/8 | 5.00 mm |
| I/9 | 5.50 mm |
| J/10 | 6.00 mm |
| K/10.5 | 6.50 mm |
| L/11 | 8.00 mm |
| M/13 | 9.00 mm |
| N/15 | 10.00 mm |
Always check you’re using the correct hook size for your yarn and pattern.
