Bulky vs Super Bulky Yarn: What’s the Difference?
Share
Ever walked into a yarn store and felt totally lost trying to pick between all the different types? You're not alone! Yarn comes in all sorts of thicknesses, and two that often get mixed up are bulky and super bulky. They might sound similar, but knowing the difference can really change how your projects turn out. Let's break down what makes bulky vs super bulky yarn unique, so you can pick the perfect one for your next crafting adventure.
Key Takeaways
- Bulky yarn (Category 5) is thick and works up pretty fast, great for things like hats and scarves.
- Super bulky yarn (Category 6) is even thicker, making projects super quick and chunky, perfect for big blankets or cozy wearables.
- The Craft Yarn Council sets the standards for yarn weights, helping you know what to expect from each category.
- Wraps Per Inch (WPI) is a good way to figure out yarn thickness if the label isn't clear; lower WPI means thicker yarn.
- Always check your pattern's recommended yarn weight and do a gauge swatch to make sure your project comes out the right size.
Understanding Yarn Weight Categories
Before we get into the specifics of bulky versus super bulky yarn, it's important to understand the broader system of yarn weight categories. This helps ensure you're using the right yarn for your project and achieving the desired results. Think of it as learning the language of yarn! It might seem a little confusing at first, but once you get the hang of it, it'll make your crafting life so much easier.
The Craft Yarn Council Standards
The Craft Yarn Council (CYC) has established a standard yarn weight system that most yarn manufacturers follow. This system categorizes yarn into different weights, numbered from 0 (Lace) to 7 (Jumbo). These numbers help crafters easily identify the thickness of the yarn. It's a pretty handy system, and most patterns will reference these numbers or the corresponding weight name (like
Distinguishing Bulky From Super Bulky

It's easy to mix up bulky and super bulky yarn, especially since the names themselves are pretty similar! But there are some key differences that will affect your projects. Let's break it down.
Thickness and Ply Differences
Bulky yarn is thicker than worsted weight yarn, but super bulky yarn is even thicker. Think of it like this: bulky is chunky, and super bulky is extra chunky. While ply isn't always a perfect indicator, bulky yarns are often around 12 ply, while super bulky yarns can be 14 ply or more. The difference in thickness impacts the speed of your projects and the overall look. Super bulky yarn for hats will create a very dense, warm fabric, while bulky yarn offers a bit more drape.
Wraps Per Inch (WPI) for Bulky vs. Super Bulky
Wraps Per Inch (WPI) is a useful way to measure yarn thickness. It involves wrapping the yarn around a ruler and counting how many wraps fit within an inch.
Yarn Weight | WPI |
---|---|
Bulky | 6-9 |
Super Bulky | 5-6 |
A lower WPI number indicates a thicker yarn. As you can see, super bulky yarn has a lower WPI than bulky yarn, confirming its greater thickness. This measurement can be helpful when substituting yarns in a pattern.
Project Suitability for Each Weight
Bulky yarn is great for projects where you want some warmth and texture, but still want the fabric to have some drape. Super bulky yarn is ideal for projects where you want maximum warmth and a very chunky look.
Here's a quick guide:
- Bulky Yarn: Sweaters, scarves, hats, blankets, cowls. Good for textured stitches.
- Super Bulky Yarn: Quick-knit blankets, chunky scarves, hats, cowls. Best for simple stitch patterns to show off the yarn's thickness.
Choosing between bulky and super bulky yarn really comes down to the look and feel you're going for. Consider the drape, the stitch definition, and how quickly you want the project to work up. A bulky coffee bean cowl will have a different texture than one made with super bulky yarn, even using the same pattern.
Ideal Projects for Bulky Yarn
Quick-Working Garments
Bulky yarn is fantastic when you want to make something relatively quickly. Think about a simple sweater that you can finish in a weekend, or a vest that adds a layer of warmth without taking forever to knit or crochet. The thicker yarn means fewer stitches and rows, so your project grows faster. I made a chunky cardigan last fall using bulky yarn, and it was so satisfying to see it come together so fast. It's also great for last-minute gifts!
Cozy Accessories
Bulky yarn is perfect for creating warm and snug accessories. Hats, scarves, and cowls are all excellent choices. These projects don't require a ton of yarn, and they work up super fast. I love making scarves with bulky yarn because they're so plush and warm. Plus, you can experiment with different stitch patterns to add texture and visual interest. Here are some ideas:
- Chunky knit beanies
- Oversized, cozy scarves
- Textured cowls
- Quick-to-make mittens
Home Decor Applications
Don't limit bulky yarn to just wearables! It's also great for adding texture and warmth to your home. Think about making chunky blankets, cushion covers, or even baskets. These projects can add a cozy, rustic touch to any room. I've seen some amazing chunky knit blankets made with bulky yarn, and they look so inviting. Plus, they're surprisingly easy to make, even for beginners. You can also use it for:
- Chunky knit blankets
- Textured cushion covers
- Sturdy baskets
- Wall hangings
I once made a set of cushion covers using bulky cotton yarn, and they added such a nice, cozy feel to my living room. It was a simple project, but it made a big difference in the overall look and feel of the space. Plus, they're super durable and easy to wash, which is always a bonus.
Ideal Projects for Super Bulky Yarn
Super bulky yarn is fantastic when you want a project done fast. It's also great for adding a lot of texture and visual interest. Because of its thickness, it's not always the best choice for intricate patterns, but it shines in simple, bold designs. Let's explore some project ideas:
Fast and Chunky Creations
Super bulky yarn is the go-to for projects you want to finish in a single evening. Think last-minute gifts or when you just need that instant gratification of seeing something come together quickly. Here are a few ideas:
- Cowls: A simple super bulky cowl can be whipped up in a couple of hours, providing warmth and style.
- Headbands: These are even faster than cowls and a great way to use up leftover yarn.
- Boot cuffs: Add a cozy touch to your boots with some chunky boot cuffs.
Warm Wearables
When the temperature drops, super bulky yarn can be your best friend. It creates incredibly warm and snuggly items perfect for winter. Here are some ideas:
- Hats: A super bulky beanie is a classic for a reason – it's warm, stylish, and quick to make.
- Scarves: Create a statement scarf with interesting stitch patterns to show off the yarn's texture.
- Sweaters: While they require more yarn and time than smaller projects, a super bulky sweater is the ultimate in cozy warmth. Just be mindful of the weight of the finished garment.
Large-Scale Home Items
Super bulky yarn isn't just for wearables; it's also excellent for adding texture and warmth to your home. Here are some ideas:
- Blankets: A super bulky blanket is a showstopper. It's heavy, warm, and adds a luxurious feel to any room.
- Pillows: Create textured pillows to add visual interest to your sofa or bed.
- Floor poufs: These are a fun and functional way to add extra seating to your living space.
Working with super bulky yarn can be a bit different than finer yarns. Because of its thickness, it's important to choose simple stitch patterns that allow the yarn's texture to shine. Also, be mindful of the weight of the finished project, especially for larger items like blankets and sweaters. Don't be afraid to experiment with different needle or hook sizes to find what works best for your yarn and project.
Recommended Bulky Yarn Brands

Bulky yarn is fantastic for quick projects, and there are tons of brands out there offering great options. It can be tough to pick, so here are some of my favorites, broken down by fiber type. Finding the right yarn can really make or break a project.
Soft Wool Blends
When you want something cozy but also easy to care for, wool blends are the way to go. They give you the warmth of wool with added durability and often a softer feel.
- Lion Brand Hue + Me: This is a popular choice because of its wide range of colors and the wool-acrylic blend makes it both warm and easy to care for. I've used it for beanies and found it to be a great, affordable option. You can find a wide selection of bulky yarns at most craft stores.
- Knit Picks Biggo: This yarn is a wool and nylon blend, which gives it a nice drape and a bit of stretch. It's super soft, though it can get a little fuzzy over time. A fabric shaver can easily fix that, though!
- Swish Bulky: This yarn from KnitPicks is 100% merino wool and is super soft. It's great for beanies and cowls, and would probably make a nice sweater too!
Durable Cotton Options
Cotton bulky yarn is great for projects that need to be sturdy and washable. Think home decor items or garments that will see a lot of wear.
- Knit Picks Billow: This is a bulky cotton yarn with a slightly thick and thin texture. It's soft, durable, and comes in a bunch of nice colors. I used it for coasters, and they've held up really well.
Versatile Acrylic Choices
Acrylic yarns are budget-friendly and come in a huge range of colors. They're also easy to care for, making them a good choice for beginners or for projects where washability is key.
- Paintbox Yarns Simply Chunky: This is a great, affordable acrylic option that comes in a ton of colors. It's soft for an acrylic and works up quickly. It's a solid choice if you need a lot of yarn without breaking the bank.
Choosing the right yarn really depends on your project and your personal preferences. Consider the fiber content, the color options, and the care instructions before making your final decision. Don't be afraid to try out a few different brands to see what you like best!
Recommended Super Bulky Yarn Brands
Super bulky yarn is fantastic for those projects you want to finish fast. It's thick, cozy, and creates a really chunky look. But with so many options out there, which brands are worth your time and money? Let's explore some recommendations.
Luxurious Wool Varieties
When you want to treat yourself (or someone else!), luxurious wool is the way to go. These yarns are often single-ply or roving style, giving them a unique texture and incredible softness. They're perfect for statement pieces that you'll treasure for years to come.
- We Are Knitters: The Wool This yarn is super thick and fluffy, creating a flawless texture. It's great for hats and blankets. I've heard people rave about its quality and the speed at which projects work up.
- Wool and the Gang: Crazy Sexy Wool Very similar to "The Wool," this is another excellent choice for luxurious projects. The decision often comes down to color selection and personal preference for ordering. Both brands offer a wide range of beautiful shades.
- Malabrigo Rasta While technically a super bulky yarn, it often feels more like a jumbo. The hand-dyed colors are absolutely stunning, and the yarn is incredibly soft. It's a splurge, but worth it for special projects.
Working with super bulky wool can be a dream. The stitches are so easy to see, making it great for beginners. Plus, the finished projects are incredibly warm and cozy – perfect for those cold winter months.
Roving Style Yarns
Roving yarns are essentially unspun wool, which gives them a very soft and airy feel. They work up quickly, but they can also be a bit delicate, so they're best suited for projects that won't see a lot of wear and tear. These are great for warm wearables.
- Tuff Puff from KnitPicks: This yarn is similar in weight and texture to "The Wool" and "Crazy Sexy Wool," but it's not quite as soft. If you're sensitive to wool, you might want to avoid this one. However, it's a good option if you're looking for a more affordable roving yarn.
- Lion Brand Wool-Ease Thick & Quick: This is a widely available and relatively inexpensive roving yarn. It's a good choice for beginners who want to experiment with super bulky yarn without breaking the bank. It comes in a wide range of colors, too.
- Cascade Yarns Magnum: This is another popular roving yarn that's known for its softness and beautiful colors. It's a bit more expensive than Lion Brand Wool-Ease Thick & Quick, but it's worth the splurge if you want a higher-quality yarn.
Affordable Alternatives
Super bulky yarn can be expensive, especially if you're working on a large project. Luckily, there are some affordable alternatives that won't break the bank. These yarns may not be as soft or luxurious as the wool options, but they're still a great choice for many projects.
- Bernat Blanket Yarn: This is a super soft and plush chenille-style yarn that's perfect for blankets and other cozy projects. It's very affordable and comes in a wide range of colors. However, it can be a bit slippery to work with, so it's not the best choice for beginners. Users have expressed satisfaction with their purchase and intend to buy it again.
- Premier Yarns Mega Tweed: This is a tweed yarn that's made from a blend of acrylic and wool. It's a good choice for projects that need to be durable and easy to care for. It's also relatively inexpensive.
- Big Twist Chunky: Available at Joann Fabrics, this is a budget-friendly acrylic option that comes in a variety of solid colors. It's a good choice for practicing new stitches or making quick projects.
When choosing a super bulky yarn, consider the project you're planning to make, your budget, and your personal preferences. With so many great options available, you're sure to find the perfect yarn for your next creation!
Choosing the Right Needles and Hooks
Okay, so you've picked out your yarn, now comes the fun part: figuring out what size needles or hooks to use! It can feel a little overwhelming, but don't worry, it's not rocket science. The right tools can really make or break your project, so let's get into it.
Needle Sizes for Bulky Yarn
Bulky yarn generally works best with larger needles. We're talking sizes US 9 (5.5 mm) to US 11 (8 mm), but it really depends on the specific yarn and the gauge you're aiming for. The yarn label will usually give you a recommended needle size, and that's a great place to start. But don't be afraid to experiment! If your fabric is too dense, go up a needle size. If it's too loose and floppy, go down a size.
Hook Sizes for Super Bulky Yarn
When you're dealing with super bulky yarn, you're going to need some seriously big hooks. Think sizes US M/13 (9 mm) and up. Again, the yarn label is your friend here, but it's all about getting the right tension. Super bulky yarn projects work up fast, so you'll quickly see if you need to adjust your hook size. For example, if you're making a blanket and it's turning out too stiff, try a larger hook.
Importance of Gauge Swatching
I cannot stress this enough: gauge swatching is KEY. Seriously, don't skip this step! It might seem like a waste of time, but it will save you so much frustration in the long run. Here's why:
- It helps you determine if your needle/hook size is right for the yarn and pattern.
- It ensures your finished project will be the correct size.
- It allows you to practice the stitch pattern and get a feel for the yarn.
Basically, a gauge swatch is a small sample of your project that you make before you start the real thing. You measure the number of stitches and rows in a 4-inch square (or whatever the pattern specifies) and compare it to the pattern's gauge. If your gauge doesn't match, adjust your needle/hook size accordingly. Trust me, it's worth the effort!
And if you're working with larger needles, make sure to check the metric measurements too!
Wrapping It Up: Bulky vs. Super Bulky
So, there you have it. Bulky and super bulky yarns are both awesome for making cozy stuff, but they're not exactly the same. Bulky yarn is great for things like sweaters and hats, giving you a nice, warm fabric that still has some drape. Super bulky, though, that's when you want something really chunky and fast. Think big blankets or super thick scarves. It all comes down to what you're trying to make and how quickly you want to finish it. Either way, you're going to end up with something soft and snuggly. Happy crafting!
