Yarn weights refer to the thickness of yarn strands, a crucial aspect for knitters, crocheters, and textile artists. They range from lace (fragile) to super bulky (very thick), with several categories in between, like fingering, sport, worsted, and chunky. The weight of the yarn influences the drape, texture, and gauge of the final project, making it essential to choose the right weight for specific patterns. Lighter weights like lace and fingering are ideal for delicate shawls and socks, while heavier weights like worsted and bulky are better for sweaters and blankets.

Why Yarn Weight Matters?

Yarn weight matters significantly in knitting, crocheting, and other yarn crafts for several reasons:

• Gauge Matching: If the yarn weight doesn’t match the pattern’s requirements, the size and fit of the finished project can be drastically affected.
• Texture and Drape: Different yarn weights create different textures and drapes in the finished product. Lighter yarns like lace or fingering weight yield delicate, fine textures suitable for lightweight garments. 
• Project Suitability: Certain projects work better with specific yarn weights. For instance, finer yarns are typically used for detailed patterns like lacework.
• Stitch Definition: The weight of the yarn affects how well stitches are defined in the finished product. 
• Time and Effort: Heavier yarns can be worked up more quickly, making them a good choice for larger projects or when a quick result is desired. 
• Comfort and Wearability: The yarn’s weight affects the finished item’s warmth and breathability. Heavier yarns are warmer and suitable for winter garments and accessories.

Selecting the appropriate yarn weight is essential to ensure that the project turns out as intended in terms of aesthetics and functionality.

How to Measure Yarn Weights?

Measuring yarn weight involves determining the thickness of the yarn, which is essential for ensuring consistency in knitting and crocheting projects. Here are the standard methods to measure yarn weight:

• Wraps Per Inch (WPI): This is the most common method for measuring yarn weight. To perform a WPI test, wrap the yarn around a ruler or a WPI tool, ensuring each wrap is snug but not overlapping or stretched. 
• Using a Yarn Gauge Tool: Some yarn gauge tools not only measure WPI but also have slots or holes to measure the yarn’s thickness directly. You fit the yarn into these to determine its weight category.
• Standard Yarn Weight System: The Craft Yarn Council has a standardized yarn weight system that categorizes yarns from 0 to 7 (lace to jumbo). You can compare your yarn to the guidelines provided in this system, which include WPI, recommended needle sizes, and gauge ranges for each category.
• Comparing with Known Yarn Weights: If you have yarn whose weight you already know, you can compare the unknown yarn side by side. This can give you a rough idea of its weight category.
• Label Information: If you have the yarn’s label, it typically indicates the yarn weight either by a number (according to the Standard Yarn Weight System), a name (like “worsted” or “DK”), or both.

Super Fine (Fingering/Sock Weight)

Cons:

Review: so soft

User: Debbie Burrows

I love this yarn. I made a shawl with it. Used almost two skeins since it is so delicate, but it is just lovely. Any pattern you are looking at that says you need only one skein, if you are using this yarn get two due to the size of the yarn. I’ll get more later on for another project.

Review: A nice soft, thin yarn

User: Amazon Customer

The “sparkle” is more of a very thin thread that you need to make sure is being worked with the hook, but otherwise it looks very nice, it’s really soft, and it’s a nice, consistent shade of white. It is a pretty thin yarn though. I use a 3.25mm crochet hook with it for amigurumi. Maybe I’d use up to a 4.5 or 5 for a granny square.

Review: Very soft, quality is great, bit thinner than expected

User: Ben

Great yarn, consistent and very soft, plus the colors are beautiful – the thickness is more like a light worsted than Aran weight, but that wasn’t too surprising given the other reviews. Not sure if I’d do a large project with it, but it’s perfect for smaller projects.

Review: EXCELLENT customer service, soft yarn!

User: Kendra

At first I was disappointed because I ordered the 3 skein pack of eggplant wool yarn. The yarn was GREAT! But, I was annoyed that I only received one. I contacted the seller, right before Thnxgiving and I was surprised to get a reply. They apologized and offered to replace them if I returned the package. I had already started my holiday knitting and didn’t want the delay. When I explained this they sent me the missing skeins EVEN though it was right before a major holday, right away. Same day! They understood my needs and were on top of it. Very good customer service!
Now for the yarn… super soft, stretchy and easy to work with. It has a little bit of fuzz (which I wanted for my beanies) and is warm and a gorgeous color I must say. Not the heaviest or warmest yarn, but perfect for projects that you want softness next to the skin. Great for lace work because it holds its sape and stretches for blocking nicely. I will be back for more!!

Review: Endless possibilities

User: Memory lane

When it comes to how you use this yarn, the possibilities are pretty much limitless.
Being close to its raw form, this all wool fiber will be prefect for dyeing, felting, weaving, or even making other yarns.

While my guess is this will appeal most to those who do a lot of felting projects, I decided to knit some up for fun.
With only a single strand and no twist, you obviously need to be careful when knitting this because your needles can slip right through it and if you pull too tight, it will fray or break.
