Easy Long Sleeve Crochet Sweater Free Pattern
If you’ve been searching for a cozy, stylish sweater you can actually make yourself without pulling your hair out, you’ve landed in the right place. This easy long sleeve crochet sweater pattern is designed for crocheters who are comfortable with the basics and ready to tackle their first wearable garment — or for experienced crafters who simply want a relaxing, satisfying project that doesn’t require a PhD in garment construction. Either way, this pattern has you covered, literally.
Crochet sweaters have been having a serious moment in the fashion world, and it’s easy to see why. They’re warm, textured, endlessly customizable, and when you make one yourself, there’s a particular kind of pride that comes with wearing it. Someone will inevitably ask where you got it, and you’ll get to say, “Oh, I made it.” That never gets old.
Let’s get into everything you need to know to make this sweater from start to finish, including materials, sizing, stitch instructions, and tips for getting the best result.
What You’ll Need Before You Start
Before diving into the pattern itself, let’s talk about supplies. Having everything gathered and ready will make your crochet experience so much smoother.
Yarn: For this sweater, you’ll want a medium weight yarn, also known as worsted weight or size 4. This is the sweet spot for a long sleeve sweater — thick enough to work up quickly, light enough that the finished garment won’t be unbearably heavy. You’ll need approximately 800–1,200 yards depending on your size. Choosing a yarn with a bit of stretch, like one that contains acrylic, wool, or a wool blend, will give your sweater a flattering drape. Pure cotton can work beautifully too, especially if you want a slightly stiffer texture that holds its shape.
Some wonderful yarn choices for this pattern include Lion Brand Pound of Love, Paintbox Yarns Simply Chunky (if you want to size up the hook), Cascade 220 for a wool option, or any basic worsted you love from your local craft store. The fiber content really is a personal choice, and budget matters too, so don’t feel like you need an expensive yarn to make something beautiful.
Hook: A 5mm (H/8) or 5.5mm (I/9) crochet hook works well for most worsted weight yarns with this pattern. Always swatch first to check your gauge before committing to a hook size.
Other supplies: Yarn needle for weaving in ends, scissors, stitch markers, a measuring tape, and a few locking stitch markers to mark your seams.
Gauge and Sizing
Gauge: 14 stitches and 16 rows = 4 inches (10 cm) in half double crochet with a 5mm hook.
Take the time to make a gauge swatch. I know it feels tedious and you just want to start the actual sweater, but trust me — gauge is everything when it comes to garment making. A small difference in tension across a few inches becomes a very large difference across the width of a sweater body. Swatch, measure, adjust your hook size if needed, and then begin.
This pattern is written for sizes XS through 2XL. Here are the approximate finished measurements:
XS: Bust 32–34 inches, finished garment 36 inches (includes 2–4 inches of positive ease)
S: Bust 34–36 inches, finished garment 38 inches
M: Bust 38–40 inches, finished garment 42 inches
L: Bust 42–44 inches, finished garment 46 inches
XL: Bust 46–48 inches, finished garment 50 inches
2XL: Bust 50–52 inches, finished garment 54 inches
This sweater is worked with positive ease, meaning it’s intended to be a bit roomy and relaxed rather than form-fitting. If you prefer a tighter fit, size down. If you love a very oversized look, size up.

Pattern Notes
This sweater is worked in pieces and seamed together. You’ll make the back panel, the front panel, and two sleeves separately, then sew them together at the shoulders and sides. The neckline is finished with a simple ribbed collar worked directly onto the seamed garment. This construction method makes it easy to try on the pieces as you go and adjust length before committing to seams.
The stitch used throughout the body is half double crochet worked in rows, which creates a dense, stretchy, and beautifully textured fabric. The slightly raised texture of hdc gives the sweater that handmade, artisan look that feels modern and cozy at the same time.
The Pattern: Back Panel
Foundation: Chain the number of stitches for your size.
XS: ch 64, S: ch 68, M: ch 74, L: ch 82, XL: ch 90, 2XL: ch 98
Row 1: Starting in the 3rd chain from the hook, hdc in each chain across. Turn. (XS: 62 sts, S: 66 sts, M: 72 sts, L: 80 sts, XL: 88 sts, 2XL: 96 sts)
Row 2: Ch 2 (does not count as a stitch throughout), hdc in each st across. Turn.
Repeat Row 2 until the piece measures 14 inches from the foundation chain for XS/S/M, or 15 inches for L/XL/2XL. This is your body length up to the armhole.
Armhole Shaping:
Row 1: Sl st across the first 4 sts, ch 2, hdc across to the last 4 sts, leave those unworked. Turn.
Row 2–4: Ch 2, hdc2tog, hdc across to the last 2 sts, hdc2tog. Turn.
You should now have the following stitch counts:
XS: 50 sts, S: 54 sts, M: 60 sts, L: 68 sts, XL: 76 sts, 2XL: 84 sts
Continue working even in hdc without decreases until the armhole measures 8 inches for XS/S, 8.5 inches for M/L, and 9 inches for XL/2XL.
Fasten off and weave in ends.
The Pattern: Front Panel
Work exactly as the Back Panel through the armhole shaping.
Once the armhole section measures 5.5 inches (for XS/S), 6 inches (for M/L), or 6.5 inches (for XL/2XL), you’ll begin the neckline shaping.
Neckline Shaping:
Work across the first third of your stitches, turn, and work on this shoulder only.
XS/S: Work across 16 sts. Turn.
M/L: Work across 18 sts. Turn.
XL/2XL: Work across 22 sts. Turn.
Decrease 1 stitch at the neck edge every row 3 times. Work even on remaining stitches until the front armhole matches the back armhole in length. Fasten off.
Rejoin yarn at the center stitches and fasten off those center stitches (this forms the front neck opening). Rejoin yarn at the remaining shoulder stitches and work the second shoulder to match, reversing shaping.
The Pattern: Sleeves (Make 2)
Foundation: Chain the following number of stitches for your size.
XS: ch 36, S: ch 38, M: ch 40, L: ch 44, XL: ch 48, 2XL: ch 52
Row 1: Starting in the 3rd chain from the hook, hdc in each chain across. Turn.
Row 2: Ch 2, hdc across. Turn.
Work in hdc, increasing 1 stitch at each end of the row every 6th row until you reach the following stitch counts:
XS: 54 sts, S: 58 sts, M: 62 sts, L: 68 sts, XL: 74 sts, 2XL: 80 sts
To increase: At the start of the row, work 2 hdc in the first stitch. At the end of the row, work 2 hdc in the last stitch.
Continue working even until the sleeve measures 17 inches from the foundation chain for XS/S, 17.5 inches for M/L, and 18 inches for XL/2XL, or your desired length.
Sleeve Cap Shaping:
Row 1: Sl st across the first 4 sts, ch 2, hdc across to the last 4 sts, leave unworked. Turn.
Rows 2–4: Ch 2, hdc2tog, hdc across to last 2 sts, hdc2tog. Turn.
Rows 5 onward: Continue decreasing 1 stitch at each end every row until 12–14 stitches remain. Fasten off.
Assembling Your Sweater
Lay your back and front panels flat, right sides together. Using a yarn needle and matching yarn, sew the shoulder seams together. Once the shoulders are joined, sew in the sleeves by aligning the center of the sleeve cap with the shoulder seam, then working outward on each side. Finally, sew the side seams and the underarm seams of the sleeves.
Before sewing any seam, pin or clip the pieces together and try the sweater on if possible. This is the moment to check length, width, and overall fit before anything is permanent. If the body feels too long, unravel a few rows before seaming. If the sleeves need to be shorter, this is the time to fix it.
Turn the sweater right side out when you’re done seaming and weave in any remaining ends.
Finishing: The Neckline
The neckline is finished with a simple ribbed band that gives the sweater a polished, professional look.
Join your yarn at one shoulder seam with a slip stitch. Work a round of single crochet evenly around the entire neckline opening, placing approximately 1 stitch per row along the vertical edges and 1 stitch per stitch along the horizontal edges. Make sure your stitch count is even.
For the ribbing, you’ll work back and forth in rows of alternating slip stitch ribbing or short row ribbing, depending on your preferred technique. A simple option:
Row 1: Ch 8, sl st in 2nd chain from hook, sl st in each chain across (7 sl sts). Sl st into the next 2 neckline sts to anchor.
Row 2: Turn, working in back loops only, sl st in each st across. Sl st into the next 2 neckline sts.
Repeat Row 2 all the way around the neckline. When you reach the starting point, sew the two ends of the ribbing together for a seamless finish.
Alternatively, you can keep it even simpler by just working 2–3 rounds of single crochet around the neckline for a clean, minimal edge.
Customizing Your Sweater
One of the best things about making your own clothes is that you’re in total control of the final product. Here are some easy ways to customize this pattern and make it completely your own.
Color: This pattern works beautifully in a single solid color for a classic look, but it’s also lovely in a tonal or heathered yarn that adds subtle visual interest. You could also add stripes by changing colors every few rows. Because the pattern is so simple stitch-wise, it’s a great canvas for letting the yarn itself do the talking.
Length: Want a cropped version? Just stop working the body earlier. For a longer tunic-length sweater, simply add more rows to the body before starting the armhole shaping. Keep track of how many rows you add so you can match it on the front panel.
Neckline style: A simple modification to the front neckline shaping can give you a deeper V-neck or a more dramatic scoop neck. To create a V-neck, start the neckline shaping earlier (when the armhole measures about 3 inches instead of 5.5 inches) and decrease more gradually. To make a boat neck, skip the neckline shaping entirely and just work both the front and back to the same height before seaming.
Hem details: Try adding a row of reverse single crochet at the bottom hem and sleeve cuffs for a tidy, slightly decorative edge. Or leave the hem completely raw if you like a more relaxed, unfinished aesthetic.
Pockets: Because who doesn’t want pockets? Crochet two simple rectangles in your main stitch and sew them onto the front body in your preferred position. A patch pocket at hip height is both practical and cute.
Tips for Crochet Sweater Success
Making a garment is a step up from most crochet projects, and a few mindset shifts can make the whole process more enjoyable.
Work slowly through the shaping sections. The armhole and neckline shaping involve more counting and attention than the plain body rows. Take your time, use stitch markers to track your decrease points, and count your stitches at the end of each row during shaping.
Block your pieces before seaming. Wet blocking or steam blocking your finished pieces before you sew them together makes assembly so much easier. Blocking evens out your tension, makes the pieces lie flat, and allows you to gently stretch or ease them to the correct measurements if needed. Pin each piece to a foam mat or blocking board and let it dry completely.
Choose your seaming method thoughtfully. The mattress stitch creates an almost invisible seam on the right side of the work and is worth learning if you haven’t already. Whipstitch is faster but more visible. If you love a fully crocheted construction, a slip stitch seam worked from the right side creates a decorative ridge that some crocheters love as a design feature.
Don’t skip the yarn tail weaving. Weave each end in two different directions using the yarn needle to lock it securely. Give the finished seam area a gentle tug to make sure nothing comes loose. Nothing is more heartbreaking than a sweater that unravels after a few wears.
Read through the entire pattern before you begin. This is advice every knit and crochet designer gives, and for good reason. Understanding where the pattern is going before you start means you’ll spot potential confusion points before you’re in the middle of a row at midnight wondering what to do next.
Caring for Your Crochet Sweater
How you wash and store your finished sweater will affect how long it looks beautiful. Always check the care label of your specific yarn, since fiber content determines washing instructions. In general, wool and wool blends should be hand washed in cool water with a gentle detergent and laid flat to dry — never hung, because wet sweaters stretch under their own weight when hanging. Acrylic yarns are typically machine washable and very low maintenance, which is one reason they’re so popular for wearables. Cotton sweaters can usually handle a machine wash on a gentle cycle.
Store your sweater folded rather than on a hanger for the same reason — garments on hangers stretch at the shoulders over time, especially heavier pieces.
A Final Note
This pattern is meant to be a jumping-off point as much as a finished project. Once you’ve made it once, you’ll have a solid grasp of how sweater construction works and you’ll be able to adapt, modify, and expand on it in all kinds of directions. Maybe the next version has a color block design, or a turtleneck, or lace panel inserts, or is worked entirely in the round with no seams at all.
Crochet clothing rewards patience and practice. If your first sweater isn’t perfect — and honestly, first sweaters rarely are — wear it anyway. The skill you built making it will carry into everything you make next.
Happy crocheting, and enjoy every stitch of your new sweater.
