There are multiple weights of yarn. They range from thread to DK and worsted weight to bulky and even more. If you look on the yarn label, there is a chart and the chart informs you of the weight of the yarn. It also gives you a recommendation for what size of knitting needles or crochet hook needed.
The weight of the yarn also determines how many stitches it takes to crochet a certain amount of inches, in this guide, it’s 4 inches. When you think about how thin or how thick yarn is, it makes sense that you’d be able to get more stitches in one inch with thin yarn than with thick, right?
Weight 0 is considered laceweight. It is super fine and is also called fingering yarn or size 10 count crochet thread. If the name hasn’t given it away already, this type of yarn is used to make lace and doilies, among other things. It can be tricky to work with due to its size. However, the end results are lovely, to say the least.
The recommended size of crochet hook for this weight is 1.5mm to 2.25mm and can fix approximately 32 – 42 double crochets in 4 inches. One thing to keep in mind with laceweight or 10 count crochet thread is that the yarn is worked on a slightly larger hook because it’s generally made into open work or lacy patterns.
Since I am so new at crocheting, I don’t have experience with working with such fine yarn but that is my next big goal! I know it probably won’t be pretty, but at least it’s a step in the right direction.
Weight 1 is considered Super Fine, and can also be called sock, fingering, or baby yarn. As you’ve probably already guessed, this kind of yarn is used for crocheting or knitting fine items, like socks and baby clothes, but is also great for shawls and lightweight items.
The recommended hook size for this weight is 2.25mm – 3.5mm and you can fit approximately 21 – 32 stitches in 4 inches.
Weight 2 is considered Fine. It can be called baby or sport yarn. It’s great for making baby items. It can also be used to make light-weight items, such as summer tank tops and baby blankets, anything that you want to be fine. One of my favorite projects that I’ve seen with this yarn is this Lost Souls Skull Shawl (say that three times fast…). I found this pattern on Raverly.com, a website that is dedicated to us crocheters and knitters alike and has tons of free patterns and ways to chat with other Hookers! Also, take note, when I say Hookers obviously I mean those of us who enjoy crocheting or knitting in our free time. 😂
The recommended hook size for this weight is 3.5mm – 4.5mm and you can fit approximately 16 – 20 stitches in four inches.
Weight 3 is Light, but it’s also called DK yarn or Light Worsted yarn. Weight 3 is great for making lighter weight blankets and for amigurumi. The recommended hook size is 4.5mm – 5.5mm and you can fix approximately 12 – 17 stitches in four inches.
Weight 4 is called Medium, worsted weight, afghan, or aran. It’s probably the most commonly used yarn as it’s great for blankets, clothing, amigurumi, hats, beanies, etc. and comes in many beautiful colors. I’ve used worsted weight yarn for most, if not all, of my projects thus far.
The recommended hook size is 5.5mm – 6.5mm and you can fix approximately 11 – 14 stitches in four inches.
Weight 5 is called Bulky but is also referred to as chunky, craft, or rug yarn. I absolutely love the look and feel of this yarn, but still haven’t found the inspiration to make anything with it! But never say never, right?
The recommended hook for this weight is 6.5mm – 9mm and you can fix approximately 8 – 11 stitches in four inches.
Weight 6 is Super Bulky or Roving. If you’re looking to make a big, thick, heavy blanket for the winter, this yarn is AMAZING! Holy cow. I have some in the Pitter Patter color; although I only have one skein and haven’t figured out what to make with it. The yarn is very soft and warm, so I’m sure you could make SO many things out of it!
The recommended hook size for this weight is 9mm – 15mm and can fit approximately 7 – 9 stitches in four inches.
Weight 7 is considered jumbo or roving, and is phenomenal for blankets especially. You could use this size of yarn for making a hand knit blanket. Although I haven’t gotten the chance to do so yet, I’d love to have hand knitting on my repertoire of things I’ve mastered! I love sticking my hands in the skeins at the craft stores. It’s like playing with the insides of a teddy bear.
It requires a hook size of 15mm or larger and you can fit approximately 6 stitches (or fewer) in four inches.
If you are more of a visual learner like I am, below is a chart that can also be very helpful! It explains everything I just said but is in a picture format. And of course, if you have any questions or comments, feel free to leave those down below.
