Are you frustrated because your crochet projects are not turning out like how they are supposed to be? You followed the patterns, you have the same exact yarns, but why do they look so different?
Well, you might have been using the wrong crochet needle sizes.
Yes, even something you think is minor like the size of your crochet hook can mess up with your final output. So to find out more about the size of the crochet hook you should be using for your project, continue reading this article.
Crochet Needle Sizes
Just like the size of the yarn you’re using for your project, the crochet needle size also has a great effect on how your project will look.
Using a smaller hook than the recommended size can result in a stiffer and denser fabric. On the other hand, if you use a larger hook, you’ll probably end up with more loose and lacey fabric.
In general, smaller yarns use smaller crochet needle sizes. The best example of this kind of yarn is the crochet thread which is used in making doilies.
To achieve the desired look, small steel crochet hooks are used when crocheting using this kind of yarn. On the contrary, bulkier yarns use larger hooks.
How to Check the Size of a Crochet Hook
A crochet hook is measured by the diameter of its hook. Sizes can range from really tiny ones that are used for thread yarns, up to large ones that are used for bulkier yarns.
In some hooks, you can easily find its crochet needle size. Steel hooks usually have their size embossed in the middle of the hook or in the grip.
Wooden hooks, on the other hand, have their size engraved in the grip of the handle.
Crochet Needle Size Standards
Choosing the right crochet hook to use can be confusing, especially when you’re trying to look for the size you need for a pattern! Have you ever wondered why there are some hook sizes in letters while some are in numbers?
The size of a crochet hook varies depending on the material used, the style of the hook, and the manufacturer of the hook. Each manufacturer can have different standards, which just adds in the confusion.
In addition to that, different locations also have different hook sizing methods. Some areas use letters in the crochet needle size. Other areas prefer to use an easier to understand method, using millimeters.
To help you understand the different hook sizing, we included an easy-to-understand conversion chart that you can refer to when you’re figuring out what hook to use!
To further understand how crochet needle sizing works, we’ll look deeper into the four most common standards used in crochet hook sizes.
Metric Crochet Hook Sizes
This is probably the easiest crochet needle size method to understand. It’s basically the measurement of the diameter of the hook in millimeters.
If you have worked on crochet thread, you probably used a Pony steel hook that uses the metric sizing. The size of this hook ranges from 2mm to .75mm.
US Crochet Hook Sizes
In the US, there are two methods used to determine the needle size. A hook can have both letter size and a number size. For example, a size B hook is just the same as a size 1 hook. A size C hook is equal to a size 2 hook.
American Numbered crochet hook size ranges from 1 up to 15. On the other hand, The American Letter crochet hook size ranges from B to Y. Bulkier yarns like the one used in the Crochet Floor Pouf requires the use of the Y hook.
UK Crochet Hook Sizes
The UK crochet needle size ranges from 14 to 000, with 14 as the smallest and 000 as the biggest. Canada also uses the same sizing method.
Based on the conversion table, the smallest size is equivalent to a 2mm hook and the biggest size is just the same as a 10 mm hook.
Steel Crochet Hook Sizes
Unlike regular hooks, the sizing in Steel Crochet hooks is in reverse. Higher number hooks are actually smaller in size.
The smallest size in US Steel hooks is 14 or .75mm, the biggest, on the other hand, is 00 which is 3.5mm. UK Steel hook sizes range from 7 (.85mm) to 0 (3.25mm).
Best Hook Size to Use For Beginners
If you’re just starting to learn how to crochet, it is best if you start with medium-sized hooks. Practice patterns usually require worsted weight yarns so this type of hooks will work. Plus it’s easier to see each of the stitches you’re making when you use medium-sized crochet needles.
