When you first start knitting or crocheting, understanding yarn weights can be confusing. One of the most common yarn weights is 4 weight yarn, also known as worsted weight. This article will explain what 4 weight yarn is, its characteristics, and how it compares to other yarn weights.
Key Takeaways
- 4 weight yarn, also called worsted weight, is a medium-thickness yarn ideal for many projects, including garments, accessories, and home decor.
- The Craft Yarn Council’s Standard Yarn Weight System helps categorize yarns from 0 (lace) to 7 (jumbo), with 4 weight being in the middle.
- Common needle sizes for 4 weight yarn are US 7-9 for knitting and I-9 to K-10.5 for crocheting.
- Gauge is crucial when working with 4 weight yarn to ensure your project turns out the correct size, with knitting gauge usually being 16-20 stitches over 4 inches.
- Substituting yarns in a pattern requires careful attention to weight and gauge to maintain the integrity of the finished project.
The Basics of Yarn Weight
Defining Yarn Weight
In simple terms, yarn weight refers to the thickness of the yarn strand. The thicker the yarn, the heavier it is considered. Conversely, thinner yarns are lighter. It’s important to note that yarn weight has nothing to do with how much the yarn weighs on a scale.
The Craft Yarn Council Standards
The Craft Yarn Council has established a set of standards to help categorize yarns based on their thickness. These standards are widely accepted and used by yarn manufacturers, designers, and crafters. The categories range from Size 0 (Lace) to Size 7 (Jumbo).

Why Yarn Weight Matters
Understanding yarn weight is crucial for several reasons:
- Consistency: It helps yarn producers maintain consistency in their products.
- Pattern Accuracy: Designers can clearly communicate which yarn to use for their patterns.
- Project Success: Crafters can choose the right yarn for their projects, ensuring the final product matches the intended design.
Knowing the yarn weight is important because it ensures that everyone is on the same page, making it easier to follow patterns and achieve the desired results.
Characteristics of 4 Weight Yarn
Common Uses for 4 Weight Yarn
4 weight yarn, often called worsted weight, is a favorite among knitters and crocheters. It’s versatile and can be used for almost any project. Here are some common uses:
- Garments like sweaters and cardigans
- Accessories such as hats, scarves, and mittens
- Home décor items like blankets and pillows
Recommended Needle and Hook Sizes
When working with 4 weight yarn, the recommended needle and hook sizes are as follows:
| Craft | Needle/Hook Size |
|---|---|
| Knitting | US 7-9 (4.5mm-5.5mm) |
| Crocheting | I-9 to K-10 ½ (5.5mm – 6.5mm) |
Gauge and Tension for 4 Weight Yarn
Gauge is crucial for ensuring your project turns out the right size. For 4 weight yarn, the common gauge over 4 inches is:
- Knitting Stockinette: 16-20 stitches
- Crochet Single Crochet: 11-14 stitches
Always check your gauge before starting a project to make sure it matches the pattern’s requirements.
Comparing 4 Weight Yarn to Other Weights
Differences Between 4 Weight and 3 Weight Yarn
4 weight yarn, also known as worsted weight, is thicker than 3 weight yarn, which is often called DK or light worsted. This difference in thickness affects the drape and warmth of the finished project. For example, a sweater made with 4 weight yarn will be warmer and bulkier compared to one made with 3 weight yarn. When choosing between these two, consider the season and the type of garment you are making.
Differences Between 4 Weight and 5 Weight Yarn
5 weight yarn, also known as bulky yarn, is significantly thicker than 4 weight yarn. This makes 5 weight yarn ideal for projects that need extra warmth and structure, like heavy blankets or winter hats. On the other hand, 4 weight yarn is more versatile and can be used for a wider range of projects, from garments to home decor. When deciding between these two, think about the desired thickness and warmth of your project.

Substituting Yarn in Patterns
How to Substitute Yarn Correctly
Every pattern either dictates the yarn you need to use to make the project or the yarn weight. This means that you have the option of making a project in the yarn you want by simply switching to a different yarn with the same weight originally called in the pattern. An important thing to note if you choose to switch out one yarn for another when working on a project is to make sure you create a gauge swatch. While most yarns within a yarn weight category are interchangeable not all yarns are identical that’s why it’s helpful to create a gauge swatch, so you can get a sense of the tension you’ll need to maintain in order to achieve the right amount of stitches per inch.
Checking Gauge When Substituting
If your pattern of choice calls for a specific yarn but you prefer to use a different yarn, you can use the yarn weights as a basis for substitution. While most yarns within a yarn weight category are interchangeable, not all are identical. It is imperative to construct a gauge swatch with the yarn that you intend to use in a project to be sure that you are matching the gauge of your project pattern.
Common Mistakes to Avoid
It can be frustrating when a certain yarn gets discontinued or if the recommended yarn for the pattern is not available in your region. To find a similar yarn, you can use this handy Yarn Substitution Tool. Simply type in the name of the discontinued or recommended yarn and it will show you suggestions for similar yarn based on the texture, fibers, qualities, gauge, size of the skein and colors.
YARN HELD TOGETHER
Some patterns call for two (or more) strands of yarn to be held together. What this means is to separate the yarn into two (or more) balls/skeins (or use multiple original skeins) and treat them as one strand of yarn.

Holding multiple strands together and crocheting normally creates a textured, dense and squishy fabric.
My Tote Bag crochet pattern uses two strands of yarn held together so that the bag straps don’t stretch and the bag is strong.
YARN HELD DOUBLE
While there could be times the designer recommends three or more strands, it’s most common for two strands to be worked together. This is called Yarn Held Double.

Best Practices for Crocheting
For crocheting, the recommended hook sizes are I-9 to K-10 ½ (5.5mm – 6.5mm). This helps in achieving the correct gauge and tension. Make sure to keep an even tension while working to avoid any inconsistencies in your project.
Care and Maintenance of Finished Projects
To keep your finished projects looking their best, follow the care instructions on the yarn label. Most 4 weight yarns can be machine washed on a gentle cycle, but always check to be sure. Proper care will ensure your projects last longer and maintain their appearance.
