The Ultimate Knit Cardigan Pattern: A Step-by-Step Guide for Every Skill Level
Few things in the world of fiber arts carry the same timeless appeal as a hand-knitted cardigan. Whether you’re a seasoned knitter who has completed dozens of projects or someone picking up needles for the first time after a long hiatus, a knit cardigan pattern offers the perfect balance of challenge and reward. The finished product — a cozy, wearable piece you created with your own two hands — never gets old, and with the right pattern and guidance, the process of getting there can be just as satisfying as wearing the result.
This guide walks you through everything you need to know to knit a classic cardigan from start to finish. We’ll cover yarn selection, needle sizing, gauge swatching, construction methods, stitch patterns, shaping techniques, and finishing details that will take your cardigan from homemade to handmade in the most beautiful sense of the word.
Why Knit a Cardigan?
Before we dive into the pattern itself, it’s worth pausing to appreciate why cardigans have remained one of the most beloved knitting projects for generations. Unlike a pullover, a cardigan opens at the front, which makes it endlessly more versatile in everyday wear. You can layer it over a dress, button it up as a standalone top, drape it open over jeans and a tee, or wrap it around yourself on a cool evening when a full coat feels like too much.
From a knitting perspective, cardigans are also deeply satisfying because they give you visible milestones to celebrate along the way. Finishing the back panel, completing your first sleeve, watching the button bands come together — every stage feels like an accomplishment. The construction is logical, the shaping is learnable, and the pattern repeat is forgiving enough that you can actually enjoy the process rather than white-knuckling every row.
Materials You’ll Need
Before you cast on a single stitch, gathering your materials thoughtfully will save you frustration later. Here’s what you’ll need for this classic, seamless top-down cardigan pattern sized for an adult.
Yarn: Choose a smooth, worsted-weight yarn (approximately 200 yards per 100g skein) for best results with this pattern. A yarn with some wool content — even a wool-acrylic blend — will have the elasticity that makes knitting easier and gives the finished garment excellent shape retention. Plan for approximately 1,000 to 1,400 yards depending on your finished size. Natural fibers like merino, Corriedale, or a superwash wool blend are ideal choices. If you prefer machine-washable options, a superwash merino or a high-quality acrylic will serve you well.
Needles: US size 7 (4.5mm) circular needles, 32 to 40 inches long. You’ll also want a set of double-pointed needles or a shorter circular needle in the same size for working the sleeves if you prefer not to use the magic loop method.
Notions: Stitch markers (at least 6), a tapestry needle for weaving in ends, removable stitch markers or locking markers for sleeve placement, a tape measure, and 5 to 7 buttons of your choosing (approximately ¾ inch to 1 inch in diameter).
Gauge: 18 stitches and 26 rows = 4 inches in stockinette stitch after blocking. Always, always swatch. A gauge swatch is not optional in garment knitting — even a half-stitch difference per inch translates to multiple inches across a sweater body, which means the difference between a cardigan that fits beautifully and one that gets stuffed in a drawer.
Understanding the Construction
This pattern uses a top-down, seamless construction, which is one of the most beginner-friendly approaches to knitting a cardigan. You begin at the neckline, work the yoke increases down to the underarms, separate the sleeve stitches, and then knit the body in one continuous piece to the hem. The sleeves are picked up and worked in the round afterward. This method means almost no seaming, very little finishing work, and the ability to try the cardigan on as you go to check the fit.
The front button bands are worked last, picked up along the finished fronts and knitted flat.
Sizing
This pattern is written for sizes XS through 3XL, with finished bust measurements ranging from 34 inches to 54 inches. Choose your size based on your actual bust measurement plus the desired ease. This cardigan is designed with approximately 2 to 4 inches of positive ease for a relaxed, cozy fit — the kind of cardigan you want to reach for on a Sunday morning with a cup of coffee, or throw over your work clothes on a crisp autumn afternoon.
Finished measurements by size:
XS: 34-inch bust, 22-inch body length from underarm, 17-inch sleeve length from underarm
S: 36-inch bust, 22.5-inch body length, 17-inch sleeve
M: 38-inch bust, 23-inch body length, 17.5-inch sleeve
L: 42-inch bust, 23.5-inch body length, 17.5-inch sleeve
XL: 46-inch bust, 24-inch body length, 18-inch sleeve
2XL: 50-inch bust, 24.5-inch body length, 18-inch sleeve
3XL: 54-inch bust, 25-inch body length, 18.5-inch sleeve
Abbreviations
Before reading through the pattern, familiarize yourself with these standard abbreviations:
CO = Cast on. BO = Bind off. k = Knit. p = Purl. pm = Place marker. sm = Slip marker. k2tog = Knit two stitches together (a right-leaning decrease). ssk = Slip, slip, knit (a left-leaning decrease). yo = Yarn over (used here for buttonholes). RS = Right side. WS = Wrong side. m1r = Make one right (a right-leaning increase). m1l = Make one left (a left-leaning increase). st(s) = Stitch(es). rep = Repeat.
The Pattern
Neckline and Yoke
Using the long-tail cast-on method, CO 68 (68, 72, 72, 76, 76, 80) sts.
Setup Row (WS): Slip 1 st purlwise, p2, pm, p10 (10, 10, 10, 12, 12, 12) sts for right sleeve, pm, p40 (40, 44, 44, 44, 44, 48) sts for back, pm, p10 (10, 10, 10, 12, 12, 12) sts for left sleeve, pm, p2, k3.
This gives you the foundation of your yoke: two front bands of 3 stitches each, sleeve sections on either side of the back, with markers delineating each raglan seam point. The slipped edge stitch at the beginning of each row creates a clean selvedge along the button band edge.
Increase Row (RS): Knit to 1 st before marker, m1r, k1, sm, k1, m1l; rep from three more times, knit to end. (8 sts increased)
WS Row: Slip 1 purlwise, k2, purl to last 3 sts, k3.
Repeat these two rows until you have completed 18 (20, 22, 24, 26, 28, 30) increase rows total, ending after a WS row. You should now have 212 (228, 248, 264, 284, 300, 320) stitches on your needles.
At this point, your yoke is deep enough to accommodate most body types. If you find that you need more depth in the yoke — particularly common for those with broader shoulders or a deeper chest — you can work additional increase rows in pairs until the yoke feels right when you try the piece on.
Separating the Sleeves
Next Row (RS): Knit across right front sts to first marker, remove marker, slip the next sleeve sts onto a length of waste yarn or stitch holder, remove second marker, CO 4 (4, 5, 5, 5, 6, 6) sts for underarm using the backward loop method, knit across back sts to third marker, remove marker, slip the next sleeve sts onto waste yarn or stitch holder, remove fourth marker, CO 4 (4, 5, 5, 5, 6, 6) sts for underarm, knit to end.
This is one of the most satisfying moments in top-down construction. In one row, your cardigan begins to look like a real garment. You now have live stitches only for the body, with your sleeves waiting patiently on holders.
Body
Work even in pattern (RS: knit across; WS: slip 1, k2, purl to last 3 sts, k3) until body measures 14 (14.5, 15, 15.5, 16, 16.5, 17) inches from the underarm, or approximately 8 inches less than your desired total body length.
Ribbing: Switch to a k2, p2 ribbing pattern for the final 2 inches of the body. This creates a gentle, elastic hem that holds its shape beautifully over time without curling or flaring.
Bind off all stitches using a stretchy bind-off method such as the k2tog bind-off or Jeny’s surprisingly stretchy bind-off.
Sleeves
Transfer one set of held sleeve stitches to your needles. With RS facing and starting at the center of the underarm, pick up and knit 2 (2, 3, 3, 3, 3, 3) sts from the cast-on underarm edge, knit across the sleeve stitches, then pick up and knit the remaining underarm stitches. Join to work in the round and place a marker for the beginning of the round.
Work 8 rounds even in stockinette.
Decrease Round: K1, k2tog, knit to last 3 sts, ssk, k1. (2 sts decreased)
Work the decrease round every 10 (9, 9, 8, 8, 8, 7) rounds until 44 (46, 48, 50, 52, 54, 56) stitches remain.
Work even until sleeve measures 15 (15, 15.5, 15.5, 16, 16, 16.5) inches from underarm, or approximately 2 inches less than your desired sleeve length.
Work k2, p2 ribbing for 2 inches.
Bind off using your preferred stretchy method. Repeat for the second sleeve.
Button Bands
The button bands are what give a cardigan its finished, polished look, and they’re worth taking your time with.
Button Band (Left Front for women’s, Right Front for men’s): With RS facing, beginning at the lower hem, pick up and knit stitches along the front edge at a ratio of approximately 3 stitches for every 4 rows. The exact count matters less than the evenness of the pickup — take your time and use removable markers to divide the front into equal sections before picking up, which helps you maintain consistency.
Work in k1, p1 ribbing for 1.5 inches. Bind off in pattern.
Buttonhole Band (Right Front for women’s, Left Front for men’s): Pick up stitches as for the button band. Work 5 rows in k1, p1 ribbing.
On the next RS row, place buttonholes evenly spaced. For a 5-button cardigan, divide your total stitch count into 6 equal sections and work a buttonhole at each of the 5 interior division points. A simple, clean buttonhole: bind off 2 sts, and on the following row, CO 2 sts over the gap using the backward loop method.
Work 5 more rows in ribbing. Bind off in pattern.
Finishing
Weave in all ends using your tapestry needle, working the yarn tails back and forth through the wrong side of the fabric in different directions for security. Block your cardigan by soaking it in cool water with a small amount of wool wash or gentle soap, pressing out the excess water in a towel (never wring), and laying it flat to the measurements listed above. Use blocking pins to encourage the edges to lie flat and the overall dimensions to match your target measurements. Allow it to dry completely before wearing — at least 24 hours for a worsted-weight garment.
Once dry, sew your buttons to the button band, aligning them carefully with the buttonholes before sewing to ensure even placement.
Tips for Customizing Your Cardigan
One of the great joys of working from a hand-knit pattern rather than buying a ready-made piece is the ability to make the cardigan truly yours. Here are a few ideas for making this pattern your own.
If you’d like a more textured fabric, try working the body in a simple seed stitch or moss stitch instead of stockinette. These stitch patterns are reversible and look particularly lovely on an open cardigan. Just be sure to swatch in your chosen stitch pattern, as textured stitches often have a different gauge than plain stockinette.
Pocket fans have a few good options here. A simple patch pocket can be knitted separately and sewn on after the fact — a 4-inch by 5-inch rectangle worked in the same yarn provides a tidy, practical pocket that adds a lovely handmade detail. Alternatively, you can work in-seam pockets during the body construction by putting a set of live stitches on a holder and picking up from the holder a few inches later, creating a seamless pocket opening.
For a more relaxed, longline silhouette, simply work additional rows on the body before beginning the ribbing hem. A cardigan that falls to the hips or even mid-thigh has a different character entirely and works beautifully over leggings or narrow trousers.
For a cropped cardigan, do the opposite — work the body for just 6 to 8 inches from the underarm before beginning the hem ribbing. Cropped cardigans have been having a sustained moment in knitting fashion, and they use significantly less yarn, making them a great option for showcasing a special skein you’ve been saving.
Choosing the Right Yarn
Yarn selection can feel overwhelming given the enormous variety available, but for a cardigan you’ll actually wear, a few guiding principles help narrow things down. First, consider fiber. Wool and wool blends are the gold standard for cardigans because wool is naturally elastic, breathable, and durable. It has memory, which means the garment returns to its shape after being worn and washed. It’s also naturally odor-resistant and can handle more wear between washes than synthetic fibers.
If wool is a concern due to allergies or skin sensitivity, look for superwash merino, which is treated to reduce the scratchy quality many people associate with wool. Alternatively, plant-based fibers like cotton or linen make lovely spring and summer cardigans, though they have less elasticity and will feel heavier in the hand while knitting.
Variegated or hand-dyed yarns deserve a word of caution in a pattern with stitch detail or shaping. The color changes in heavily variegated yarns can obscure the elegance of your stitch work and make it hard to see your increases, decreases, and button bands clearly. Semi-solid or tonal yarns — those with subtle variation in a single color family — are generally more flattering to garment knitting and let the construction shine. That said, a bold colorway can be absolutely spectacular in a simple stockinette cardigan with no competing texture.
A Final Word
A hand-knitted cardigan is not a fast project, and it shouldn’t be. It’s a project that unfolds across evenings and weekends, that accompanies you through seasons and conversations and quiet hours. When you wear the finished piece, there’s a particular pride in saying “I made this” — one that doesn’t diminish over time or with repeated wearings.
Whether this is your first garment or your fiftieth, we hope this pattern gives you a framework that feels approachable without being limiting, detailed without being rigid. Cast on, enjoy the rhythm of the needles, and trust the process. Your cardigan is waiting.
