Choosing a Crochet Hook Size with Confidence

 

One thing that can get kind of tricky when crocheting is figuring out hook sizes. The thing with crochet is that the continuity in hook sizing isn’t always spot on. Not all brands match up with the others when it comes to the letter or number labeling. This makes it difficult when a pattern calls for a certain gauge and they give a letter and/or number for the hook size. One of the things I have learned is to ALWAYS check the hook size listed in millimeters.

Another thing to watch out for in today’s world (thanks to the internet) is that we have access to as many patterns as our little hearts desire. Even if they are from other countries. Sometimes these sizes are listed from a whole different scale than we’re used to. This makes it even more important to pay attention to the size they are actually asking for in the pattern.

Here is a chart of some of the more popular hook brands. There are many more, but I am using these just as an example.

As you can see most of the hooks are matched up, especially the more popular sizes. The larger sizes have just become more popular as super thick chunky yarns have started to emerge. The hook companies started making larger hooks to accommodate these new yarns, but I don’t think there was a set of standards to follow.

The bottom line is that you should always pay attention to the size of the hook in mm so that no matter what brand hook you use or from which country the pattern originated, there is a uniform place to start. I hope this also helps you when you are trying to reach the proper gauge with your projects. If you know exactly where your starting point is, you know which way to go to reach your gauge.

May Your stitch count be true and your frogs be few!
