Chunky Crochet Raglan Sweater – Free Pattern – Ned and Mimi

There is something deeply satisfying about wrapping yourself in a sweater you made with your own hands. The weight of chunky yarn, the rhythm of each stitch, the slow transformation of a skein into something wearable — it’s one of those crafting experiences that never gets old. If you’ve been searching for a cozy, beginner-friendly project that delivers impressive results without an overwhelming stitch count, this Chunky Crochet Raglan Sweater is exactly what you’ve been looking for. Here at Ned and Mimi, we believe that free patterns should be genuinely helpful, clearly written, and enjoyable from cast-on to bind-off (or, in our case, from foundation chain to final weave-in). So let’s dive in.

Why a Raglan Sweater?

Before we get into the pattern itself, let’s talk about why the raglan construction is such a brilliant choice for crocheters — especially those who are newer to garment making.

A raglan sweater is worked from the top down, with diagonal increase lines that radiate outward from the neckline to create the shoulders and body in one seamless (or nearly seamless) piece. This construction style has several advantages. First, it’s forgiving. Because you’re building the sweater as you go, you can try it on as you work and adjust the length of the body or sleeves to suit your exact measurements. Second, it’s intuitive. Once you understand the increase pattern, the logic of the sweater becomes clear, and you’ll find yourself working almost on autopilot. Third, it produces a flattering fit. The diagonal raglan lines are universally flattering and give the finished garment a clean, modern silhouette that looks intentional and polished.

Combine that construction style with chunky yarn and a simple stitch pattern, and you have a project that works up quickly and looks genuinely impressive — whether you’re making it for yourself, a partner, a teenager, or a gift.

Materials You’ll Need

One of the best things about chunky crochet projects is that the supply list stays short and sweet. Here’s what you’ll need to make this raglan sweater.

Yarn: You’ll want a bulky or super bulky weight yarn, falling roughly into the category of weight 5 or 6 on the standard yarn weight scale. Look for something with good stitch definition so the raglan lines and texture read clearly. Wool blends, acrylic, and wool-acrylic mixes all work beautifully here. The yardage will depend on your size, but plan for approximately 600–900 yards for a small or medium, and 900–1,200 yards for a large or extra-large. Always buy a little extra to avoid running short mid-project.

Hook: A 6.5mm (K/10.5) or 7mm (K or L) crochet hook works well with most chunky yarns. Check your gauge swatch (more on that shortly) and adjust up or down as needed.

Notions: You’ll need a yarn needle for weaving in ends, stitch markers (at least four), scissors, and a measuring tape. If your pattern includes a zipper, buttons, or any other closure, have those on hand before you finish the neckline.

Optional: A spare length of scrap yarn or stitch holders to hold the sleeve stitches while you work the body. This is especially helpful if you’re new to top-down construction and want to keep everything organized.

Gauge and Sizing

Let’s have an honest conversation about gauge, because it’s the single most important step between a sweater that fits and one that ends up as a very expensive dishcloth.

With a 7mm hook and a chunky weight yarn, a typical gauge is around 10–12 stitches and 10–12 rows per 4 inches (10 cm) in half double crochet or whatever stitch pattern you’re using. However, every crocheter works at a slightly different tension, and every yarn behaves differently, so your gauge will almost certainly vary from this baseline.

To check your gauge, crochet a swatch of at least 6 inches by 6 inches, block it the way you plan to block your finished sweater, and then measure the center 4 inches. Count the stitches and rows in that 4-inch square. If you have more stitches than the pattern calls for, try a larger hook. If you have fewer, try a smaller one.

It feels tedious. We know. But a gauge swatch takes maybe 20–30 minutes, and it can save you from spending 20+ hours on a sweater that doesn’t fit your body. Think of it as a small investment in a big payoff.

This pattern is written in sizes XS, S, M, L, XL, and 2XL, with finished bust measurements ranging from approximately 36 inches to 58 inches, designed to be worn with 4–6 inches of positive ease. Positive ease means the finished sweater is larger than your actual bust measurement, which is what gives it that relaxed, oversized feel. If you prefer a closer fit, size down.

Stitch Glossary

This pattern uses a small handful of stitches that even beginners will find manageable. Here’s a quick reference.

Ch — Chain stitch. The foundation of almost everything in crochet.

Sl st — Slip stitch. Used here to join rounds and create invisible seams.

Sc — Single crochet. A short, dense stitch used for the neckband.

Hdc — Half double crochet. This is the primary stitch of the sweater body. It’s taller than a single crochet but shorter than a double crochet, which gives the fabric a nice density without being too stiff.

Hdc2tog — Half double crochet two together. A decrease stitch used sparingly for shaping.

BLO — Back loop only. Working in the back loop creates a subtle ribbed effect, used in the cuffs and hem band.

Inc — Increase. In this pattern, an increase means working two hdc into the same stitch.

If you’re unfamiliar with any of these stitches, a quick video tutorial will show you exactly what you need. There is an abundance of excellent free crochet stitch tutorials online, and none of the techniques in this pattern require anything beyond basic skills.

The Pattern

Setting Up the Yoke

The sweater begins at the neckline with a foundation chain. For a medium size, chain 48 and join with a slip stitch to form a ring, being careful not to twist the chain.

Place stitch markers at four points along the chain: these mark the four raglan corners where your increases will happen every row. In a standard raglan setup, these four markers divide your chain roughly into sections for the back, two sleeves, and the front. A common division for a medium adult sweater looks like this: 14 stitches for the back, 7 stitches for each sleeve, and 14 stitches for the front, with one stitch at each of the four raglan points (the four marker stitches themselves). These numbers will shift as you work increases, so getting comfortable moving your markers up each row is key.

For rows 1 through approximately 18–22 (depending on your size), you’ll work in the round, increasing at each of the four raglan markers on every round. An increase round looks like this: work in hdc across to one stitch before the marker, work 3 hdc into the marker stitch (the center stitch gets the marker), then continue across to the next marker stitch. Repeat at all four corners. You’re adding 8 stitches per round — 2 at each raglan line.

Work these increase rounds until your yoke is deep enough to comfortably reach from the back of your neck to just below the armhole. For most adults, this is between 8 and 10 inches.

Separating the Sleeves

Once your yoke is the right depth, it’s time to separate the sleeve stitches from the body stitches. This is where the fun really begins, because suddenly it starts to look like a sweater.

Work across the front stitches in hdc, then when you reach the first sleeve section, place those sleeve stitches on a holder (a length of scrap yarn works perfectly), chain 4–6 stitches to bridge the underarm gap, and continue across the back stitches. When you reach the second sleeve section, repeat the process — place the sleeve stitches on hold, chain across the underarm, and join to continue working in the round on just the body stitches.

The number of underarm chain stitches affects the width of your underarm and should be adjusted to suit your measurements. For most medium to large adult sweaters, 4–6 chains is about right.

Working the Body

Now you have a closed ring of stitches that forms the body of your sweater. Work even rounds of hdc (no more increases or decreases, unless you want to taper the waist) until the body reaches your desired length. For a standard pullover, this typically means working until the body is about 15–17 inches below the underarm, but try it on as you go and stop when it hits the length you love.

At this point, you have a choice: leave the hem as-is for a simple straight edge, or work a ribbed band by switching to working in the back loop only for 2–3 inches. The BLO hem band adds a nice finished look and gives the hem a gentle elasticity that helps the sweater keep its shape over time.

Fasten off and weave in your ends.

Working the Sleeves

Return to the held sleeve stitches on one arm. Place them back on your hook, pick up the chain stitches at the underarm (picking up stitches evenly along the chain), and join to work in the round.

Work even rounds of hdc for the sleeve length, and here’s an important tip: if you want a tapered sleeve that’s narrower at the wrist, work a decrease round every 6–8 rounds by working an hdc2tog at the beginning and the end of the round. This will gradually reduce the sleeve circumference and give you a more fitted lower sleeve.

Continue until the sleeve reaches the length you want — typically wrist-length for a classic sweater, or a couple of inches shorter if you prefer a three-quarter sleeve. Finish with the same ribbed cuff in BLO that you used for the hem, for a cohesive look.

Repeat for the second sleeve.

The Neckband

Return to the neckline. Working along the foundation chain edge (or along the first row of the yoke, depending on how you constructed it), join yarn and work one round of sc evenly around. For a slightly ribbed neckband, work 2–3 additional rows in BLO sc, then fasten off.

If you prefer a folded turtleneck or a deep cowl neck, simply continue working the neckband for as many rows as you like. The BLO method keeps it stretchy enough to pull over your head comfortably.

Finishing Touches

Weave in all remaining ends with your yarn needle. If your yarn is wool or a wool blend, wet blocking will do wonders for the finished garment — gently wash it in cool water with a little wool wash, press out the excess water in a towel (don’t wring), and lay it flat to dry in the measurements you want. Blocking evens out any tension inconsistencies and gives the fabric a lovely drape and softness.

If you’re using a purely acrylic yarn, steam blocking is an option, though some acrylics don’t respond well to it. Check your yarn label, and when in doubt, skip the heat and just lay it flat to dry naturally.

Tips for Getting the Best Results

A few things we’ve learned from making this sweater (and sweaters like it) over the years:

Work your gauge swatch in the round if the pattern is worked in the round, since many crocheters work differently in flat rows versus joined rounds. A flat swatch won’t always give you accurate information for a circular project.

Use locking stitch markers rather than open-ring markers for the raglan points. With chunky yarn and fast increases, it’s easy for markers to slip out during a round, and locking markers stay put reliably.

If you find the neckline too tight or too loose after working a few rounds of the yoke, don’t be afraid to rip back and adjust the foundation chain. It’s much easier to fix this early than after you’ve completed the entire yoke.

When picking up the underarm stitches, err on the side of picking up slightly more stitches rather than fewer. A small gap at the underarm is the most common finishing complaint in top-down sweaters, and a few extra stitches will close that gap neatly. You can always decrease those extra stitches away in the first round of sleeve working.

Don’t skip the swatch. We’ve said it once, and we’ll say it again, because it really does make a difference.

Yarn Suggestions

If you’re wondering where to start when choosing your yarn, here are a few favorites that work beautifully for this type of project.

For a rustic, cozy feel, a chunky single-ply wool like a Peruvian wool or a merino-alpaca blend gives the finished sweater beautiful stitch definition and incredible warmth. These natural fibers also tend to bloom a little after washing, which fills in any slight gaps in the fabric.

For a more budget-friendly option that’s also machine washable, a chunky acrylic or acrylic-wool blend is a wonderful choice. Many of these come in huge yardage skeins, which means you often need fewer of them, and the wide color palette available in acrylic is hard to beat.

For a luxurious gift or special-occasion knit, a chunky cashmere blend will produce a sweater so soft that the recipient might never take it off.

Whatever yarn you choose, read the label carefully and check the recommended hook size as a starting reference point before you begin your swatch.

Making It Your Own

One of the best things about a simple, well-constructed pattern like this one is how much room it leaves for customization. Here are a few ways to make this sweater uniquely yours.

Add a pocket by crocheting a small rectangle in the same stitch pattern and sewing it to the front body panel. A single patch pocket sits beautifully on a chunky sweater and adds a practical detail.

Change the stitch pattern in the body for texture. Once you understand the increase logic of the yoke, you can switch the body stitch to a moss stitch, a shell stitch, or any other simple textured stitch you love, as long as it works within your stitch count.

Play with stripes by changing color at any round join. Because this sweater is worked in the round, color changes are invisible if you keep track of your round starts.

Add a button band to the front neckline and work the sweater open in the front (like a cardigan) instead of as a closed pullover. This requires a small adjustment to the construction — you’d work flat rows for the yoke instead of in the round — but it opens up a whole new range of styling options.
