In the craft world, it’s common to hear about DK weight yarn. But what exactly is DK yarn?

In this blog post, we’ll take a closer look at DK yarn: what it is, what it’s used for, and why you would want to use it. We’ll break it down and make it easy to understand how and when to use this popular and versatile yarn.

What is DK weight yarn?

DK yarn, or double knitting yarn, is a lightweight yarn that is perfect for a wide range of knitting and crocheting projects. DK yarn falls into the Craft Yarn Council’s 3/Light category. In Europe and Australia, you might see DK yarn labeled as 8-ply yarn.

DK yarn is lighter than worsted yarn, but heavier than sport yarn. You may also hear it referred to as “light yarn” or “light worsted” yarn.

DK yarn comes in many different colors, textures, and fiber contents. It usually comes packaged as a skein or hank, but is sometimes sold as a yarn “cake.

What’s in a Name?

The “DK” in DK weight yarn stands for “double knitting.” But don’t confuse it with the “double knitting” technique! DK weight doesn’t necessarily indicate a type of project, as its name seems to imply. Instead, it’s just a term used to describe the weight of the yarn.

Characteristics of DK Weight Yarn

Now that we’ve answered the question, “What is DK weight yarn?”, let’s take a closer look at some of its characteristics.

CYC Category: DK weight yarn is classified as a “Category 3/Light” yarn according to the Craft Yarn Council’s Standard Yarn Weight System. This puts in between Category 2/Fine (commonly called sport weight) and Category 4 /Medium (commonly called worsted weight).

Recommended Needle/Hook Size: The most common knitting needle sizes for DK yarn are US size 5 to 7, or 3.75-4.5 mm. The most common hook sizes for crocheting are US sizes 7 to I/9, or 4.5-5.5 mm.

That said, the exact needle or hook size to use will depend on your project. Check your pattern to see what size needles or hooks the designer recommends.

Gauge: When knitting with DK yarn, you’ll likely get 21-24 stitches per 4-inches in a swatch of stockinette stitch. When crocheting, you’ll likely get 12-17 stitches per 4-inches in a swatch of single crochet.

Of course, your gauge will depend on your needle/hook size. Larger needles and hooks will give you lighter, looser fabric. In contrast, smaller needles and hooks will give you tighter, dense fabric.

Meters/Yards per 100g: The number of meters/yards per 100 grams varies depending on the exact yarn. However, you will generally find DK yarn to have between 190-300 meters/yards per 100 grams.

WPI: DK weight yarn measures between 11-15 WPI, or Wraps per Inch.

Ply: DK weight yarn is traditionally made up of 8 plies, or strands of yarn twisted together. (In fact, Australia and New Zealand call it “8-ply”.) But, not all DK yarn is 8-ply. You’ll see some that are made up of fewer plies.

What is DK yarn used for?

DK yarn is a great choice for so many projects! It’s versatile and comes in a wide range of colors, making it perfect for everything from hats and scarves to sweaters and baby blankets.

Since it’s a lighter-weight yarn, it’s great for garments. In particular, I love using DK yarn to make cozy sweaters that don’t look too heavy or bulky.

And, of course, DK weight yarn is also an excellent choice for double knitting and colorwork projects. (If you’re unfamiliar with the term, double knitting is a technique that allows you to create two layers of fabric on one set of needles.)

How to Check if Your Yarn is DK Weight

The easiest way to check if your yarn is DK weight is to look at the ball band or label. The ball band will tell you everything you need to know about the yarn, including the weight category. It should say “DK” or “3-Light” somewhere on the packaging.

Of course, as all yarn crafters know, you’ll sometimes find a lovely yarn in your stash that’s lost its label. Don’t worry! You can still figure out the weight of your yarn with either of these easy tests.

WPI (wraps per inch) method: Measure your yarn’s WPI to see if it falls into the DK weight category. Take your strand of yarn and wrap it around your pencil or ruler. Wrap the strands next to each other, until you’ve made enough wraps to cover 1-inch of the ruler. Count the number of strands it takes to cover 1-inch. A DK weight yarn will have between 11-15 WPI.

Gauge method: Another way to verify the type of yarn is to make a quick gauge swatch. If you’re knitting, use a pair of size 6 (4mm) needles to cast on 30 stitches. Work up a few rows in stockinette stitch. Then, see if you get a row gauge of 21-24 stitches per 4 inches/10 cm. If so, you might have DK weight yarn on your hands.

If you’re crocheting, use an H (5mm) hook to make a gauge swatch. If you have a DK weight yarn, you should get 12-17 single crochet stitches in a 4-inch swatch.
