I’ve put together a handy guide to translate between UK metric and USA crochet hook sizes. As you may know, crochet hooks come in a range of different sizes which are called by different names depending on where you are in the world. Unfortunately, this can get a little confusing when your reading patterns from around the globe.
Hook sizes explained
To begin, people like myself from country’s such as the U.K. will be used to calling their crochet hooks by the metric size, e.g. 4mm. This is simply the size of the hook shaft in millimetres. Similarly crocheters from other parts of the world such as the US will have a letter/number name for their hook sizes, e.g. G-6. In fact, both a 4mm and a G-6 crochet hook are the same size! They’re just known by different names. Some crochet hooks will have both terms printed on them which is great. On the other hand some don’t, which is why you might find this crochet hook size guide useful.
What size crochet hook do you need?
If your following a crochet pattern, the pattern should clearly state which hook you should be using. But be aware you may not need to use that hook size. After completing your gauge swatch you may need to adjust your hook size to match the tension used in the pattern.
If you are following a stitch rather than a pattern or doing your own thing check your yarn packaging for a recommended hook size.
As a general rule the lighter the yarn weight the smaller the crochet hook will be, likewise the heavier the yarn the larger hook. That being said, you don’t have to always use the recommended hook for your yarn. Using a smaller hook will give you smaller, tighter stitches which is useful if you want a stiffer result. Alternatively, a larger hook will give you larger, looser stitches which can make your project feel more flexible and also give a softer feel.

Conversion Chart: US to UK and Beyond
If you’re working with patterns from different countries, you may encounter different sizing systems. In the US, hook sizes are typically denoted by letters, while in the UK they’re denoted by numbers, the metric system. This can lead to confusion when trying to follow a pattern from another country. But fear not! The conversion charts above should swiftly help you navigate these differences.
The Basics: What Do the Numbers Mean?
Crochet hook sizes are denoted by numbers, with larger numbers indicating larger hooks. The most common sizes are in the range of 2.25mm to 25mm, with half sizes available for some sizes. But what do these numbers actually mean? Well, they correspond to the diameter of the hook shaft. So a size 2.25mm hook has a shaft diameter of 2.25mm, while a size 25mm hook has a shaft diameter of 25mm.
Size Chart: Finding the Right Hook for Your Project
Now that you know what the numbers mean, how do you choose the right hook size for your project? The answer depends on a few factors, including the type of yarn you’re using and the desired finished product. Luckily, most crochet patterns will recommend a crochet hook size, most skeins of yarn have a hook recommendation on its packaging too. For example, a 5mm crochet hook is often recommended for worsted or aran weight yarn, which is also known as a H-8 hook.
UK vs US: What’s the Difference?
If you’re new to crochet, you may be wondering what the difference is between UK and US hook sizes. As mentioned earlier, UK hooks are denoted by numbers, while US hooks are denoted by letters. For example, a UK 4mm hook is roughly equivalent to a US size G-6 hook.
Set, Case, and Holder: Keeping Your Hooks Organized
Once you start building your collection of crochet hooks, you’ll need a way to keep them organized and easily accessible. This is where hook sets, cases, and holders come in handy. Hook sets typically come in a range of sizes and may include additional tools like stitch markers and tapestry needles. Cases and holders are designed to keep your hooks organized and protected while on the go. Some even come with built-in size labels so you never lose track of which hook is which. Just be sure to double-check your gauge and adjust your hook size as needed.
Crochet hook sizes may seem daunting at first, but with a little knowledge and the right tools, you’ll be well on your way to creating beautiful projects in no time.
