Demystifying the Size Q Crochet Hook

Let me tell you what an adventure it’s been trying to find the right size Q crochet hook. It all started with a blanket pattern that calls for a Q hook. Although I have crochet hook acquisition syndrome, I didn’t have this size in my collection. So, I set out online to find one. Since the Craft Yarn Council represents the leading yarn companies and have set the standards when it comes to crochet hook sizes, we’ll review their crochet hook size chart:

Looks like a size Q crochet hook can either be 15mm, 15.75mm or 16mm. However, a 1mm difference between the various Q hook sizes will affect the overall size of the finished project. So, now we are faced with the question which one is the correct Q crochet hook size to use? Oh, for the love of yarn why give us 3 different options?? Since there are so many options, the correct one to use comes down to what mm size the pattern calls for.

Generally, the 15mm size will be labeled either as a P/Q or Q-19, and here’s a few I found:

Clover P/Q 15mm Crochet Hook

Lion Brand Q-19 15mm Crochet Hook

Prym P 15mm Crochet Hook

Boye and ChiaoGoo are the only two brands I could locate that offer a 15.75mm crochet hook:

Boye P-16 & Q 15.75 crochet hook set

Boye  Q 15.75mm crochet hook

ChiaoGoo 15.75 Bamboo crochet hook

Now let’s take a look at the 16mm Q crochet hook. When searching online, there’s way more available than the Q 15.75mm crochet hook. These are two of them you can find, and I prefer the white Susan Bates hook because it’s lightweight with an in-line design making it easy to use.
