Easy Free Crochet Pattern: Seamless Top-Down Raglan Sweater for Babies and Kids

There is something deeply satisfying about making a garment for a child from a single strand of yarn, watching it grow from a small ring at the neckline into a complete, wearable sweater. The top-down raglan construction is one of the most beloved methods in crochet for exactly that reason. You start at the collar, increase strategically at four raglan points, and by the time you have worked your way down to the hem, you have a fully seamless sweater that requires almost no finishing. No sewing. No awkward seams pressing against a baby’s delicate skin. Just a smooth, stretchy fabric that slips over little heads with ease.

This pattern is designed for beginners who are ready to move past dishcloths and scarves, and for experienced crocheters who simply want a reliable, fast, and free pattern they can return to again and again. It is written for sizes newborn through 8 years, the yarn requirements are modest, and the construction method means you can try the sweater on as you go to check the fit before you ever reach the hem.

Whether you are making this for a new baby, a growing toddler, or a gift for someone else’s child, this pattern will walk you through every step clearly and confidently.

What You Will Need

Before you cast on, gather your materials. Having everything ready makes the process smoother and more enjoyable.

Yarn: Worsted weight yarn (category 4) works beautifully for this pattern and crochets up quickly. Choose a machine-washable yarn for practicality, since baby and children’s clothing will be washed frequently. Popular choices include Lion Brand Pound of Love, Paintbox Simply DK (held double for worsted weight), or any soft acrylic or cotton blend. You will need approximately 200–250 yards for newborn, 300–400 yards for 6–12 months, 450–550 yards for 12–24 months, 550–650 yards for 2–4 years, and 700–900 yards for sizes 5–8 years. These are approximate figures, and the actual amount depends on your gauge and any color work you choose to add.

Hook: A 5.0 mm (H/8) crochet hook is recommended as a starting point, but always crochet a gauge swatch first. The right hook size is the one that gets you to gauge, not the one printed on the label.

Notions: Stitch markers (locking style work best), a yarn needle for weaving in ends, scissors, and a measuring tape.

Gauge: 14 stitches and 16 rows = 4 inches (10 cm) in half double crochet worked in the round. Gauge is important for a fitted garment. A swatch takes only a few minutes and will save you from making a sweater that is too small or too large.

Sizing Chart

This pattern covers six sizes. Measure the child before you begin and choose the size based on chest circumference, not age, since children vary considerably in size.

Size 1 (Newborn): Chest 14 inches, finished chest 16 inches (2-inch ease), length 9 inches, sleeve length 5 inches.

Size 2 (3–6 months): Chest 16 inches, finished chest 18 inches, length 10.5 inches, sleeve length 6 inches.

Size 3 (6–12 months): Chest 17 inches, finished chest 19 inches, length 11.5 inches, sleeve length 7 inches.

Size 4 (12–24 months): Chest 19 inches, finished chest 21 inches, length 13 inches, sleeve length 8.5 inches.

Size 5 (2–4 years): Chest 21 inches, finished chest 23 inches, length 15 inches, sleeve length 10 inches.

Size 6 (5–8 years): Chest 23 inches, finished chest 25 inches, length 17 inches, sleeve length 12 inches.

All measurements are for the finished garment with approximately 2 inches of positive ease built in for a comfortable, relaxed fit.

Abbreviations and Stitch Guide

This pattern uses US crochet terminology throughout.

ch = chain
sl st = slip stitch
hdc = half double crochet
hdc inc = half double crochet increase (work 2 hdc into the same stitch)
BLO = back loop only
st(s) = stitch(es)
pm = place marker
sm = slip marker (move to next stitch as you pass it)

The entire body of this sweater is worked in half double crochet. If you would like a slightly denser fabric, you may substitute single crochet throughout, adjusting your gauge accordingly. HDC is recommended because it has a bit more drape and stretch, which is ideal for a garment that will be pulled over a child’s head repeatedly.

Construction Overview

The sweater is worked from the top down in joined rounds. You begin with a foundation chain at the neckline, join to work in the round, and then increase at four raglan points every other round (for sizes newborn through 18 months) or every round (for larger sizes) until the yoke is wide enough to separate the sleeves from the body. The sleeves are placed on hold using waste yarn, and the body is worked down to the hem. Then each sleeve is picked up and worked in the round to the cuff. There are no seams to sew, and the only finishing required is weaving in a handful of ends.

The Pattern

Step One: Neckband Foundation

Begin by chaining the number of stitches for your size. The numbers below create the foundation chain for the neckline ribbing.

Size 1: ch 45
Size 2: ch 50
Size 3: ch 54
Size 4: ch 58
Size 5: ch 62
Size 6: ch 68

Join with a slip stitch to the first chain to form a ring, being careful not to twist. Chain 1 (this does not count as a stitch throughout the pattern).

Ribbing Round: Work 1 hdc in the back loop only of each chain around. Join with a slip stitch to the first hdc. (45, 50, 54, 58, 62, or 68 stitches)

Repeat the ribbing round for 4 more rounds total, working always in the BLO and joining at the end of each round. This creates a neat, stretchy collar that hugs the neckline without feeling tight.

After the ribbing, you will work one setup round in both loops of each stitch to return to normal hdc fabric.

Step Two: Setting Up the Raglan Markers

The raglan construction relies on four increase points that divide the sweater into the back, front, and two sleeves. Before you begin the yoke increases, you need to place four stitch markers to mark these positions.

Work the setup round as follows, placing markers as you go:

Work 10 (11, 12, 13, 14, 15) stitches for the right back, pm, work 5 (6, 6, 7, 7, 8) stitches for the right sleeve, pm, work 15 (16, 18, 18, 20, 22) stitches for the front, pm, work 5 (6, 6, 7, 7, 8) stitches for the left sleeve, pm, work 10 (11, 12, 13, 14, 15) stitches for the left back.

Join with a slip stitch at the end of the round. You have divided the neckline into sections, and the four markers indicate the raglan seam points where increases will be made.

Step Three: Yoke Increases

This is the heart of the top-down construction. In each increase round, you will work 2 hdc into the stitch immediately before each marker and 2 hdc into the stitch immediately after each marker. This adds 8 stitches per increase round.

Increase Round: Work in hdc to 1 stitch before the first marker, hdc inc in the next stitch, sm, hdc inc in the next stitch. Repeat this process at each of the remaining three markers. Work to the end of the round and join.

Non-Increase Round: Work 1 hdc in each stitch around. Join.

For sizes 1 and 2 (newborn and 3–6 months), alternate increase rounds and non-increase rounds.
For sizes 3 and 4 (6–12 months and 12–24 months), work the increase round every round.
For sizes 5 and 6 (2–4 years and 5–8 years), work the increase round every round until the yoke measures 3.5 inches (size 5) or 4 inches (size 6), then alternate increase and non-increase rounds.

Continue until the total stitch count reaches the following:

Size 1: 99 stitches total
Size 2: 114 stitches total
Size 3: 126 stitches total
Size 4: 138 stitches total
Size 5: 154 stitches total
Size 6: 174 stitches total

At this point, the yoke should measure approximately 4 inches (size 1), 4.5 inches (size 2), 5 inches (size 3 and 4), 5.5 inches (size 5), or 6 inches (size 6) from the neckline.

Step Four: Separating the Sleeves from the Body

This step transforms your yoke into the main body of the sweater. You will place the sleeve stitches on hold using a length of waste yarn and work the body stitches only.

Work in hdc to the first marker (right back stitches). When you reach the marker, skip the sleeve stitches and place them on a length of waste yarn. Chain 2 (these bridge stitches fill in the underarm gap), then continue working the front stitches. When you reach the next marker, skip the second set of sleeve stitches onto waste yarn and chain 2 to bridge the underarm. Continue working the left back stitches. Join with a slip stitch.

The number of stitches now on your hook (back + front + 4 underarm chains) should be:

Size 1: 54 stitches
Size 2: 62 stitches
Size 3: 66 stitches
Size 4: 74 stitches
Size 5: 84 stitches
Size 6: 94 stitches

Step Five: The Body

Work in continuous joined rounds of hdc, working 1 hdc in each stitch around, until the body measures the following from the underarm:

Size 1: 5 inches
Size 2: 6 inches
Size 3: 7 inches
Size 4: 8 inches
Size 5: 9.5 inches
Size 6: 11 inches

You may try the sweater on the child at any point during this stage to check the length. This is one of the great joys of top-down construction.

Hem Ribbing: Work 4 rounds of hdc in the BLO. Fasten off and weave in the end.

Step Six: The Sleeves

Remove the waste yarn from the held sleeve stitches and place them back on your hook. Attach yarn and pick up 2 additional stitches from the underarm chains (1 stitch on each side of the chain gap). Join to work in the round.

Size 1: approximately 23 stitches
Size 2: approximately 26 stitches
Size 3: approximately 28 stitches
Size 4: approximately 31 stitches
Size 5: approximately 35 stitches
Size 6: approximately 40 stitches

Work even (no increases or decreases) in joined rounds of hdc until the sleeve measures:

Size 1: 3.5 inches from the underarm
Size 2: 4 inches
Size 3: 5 inches
Size 4: 6.5 inches
Size 5: 8 inches
Size 6: 10 inches

Sleeve Taper (optional for sizes 4–6): To taper the sleeve, work a decrease round every 4 rounds by working hdc2tog at the beginning and end of the round, reducing the sleeve by 2 stitches per decrease round. Work decreases until you have reduced the stitch count by 4–6 stitches total, then continue even to the cuff length.

Cuff Ribbing: Work 4 rounds of hdc in BLO. Fasten off.

Repeat for the second sleeve.

Step Seven: Finishing

Weave in all ends using a yarn needle, being thorough so the ends do not come loose during washing. Wet block the sweater gently by soaking it in cool water, squeezing out the excess moisture without wringing, and laying it flat to dry on a blocking mat or clean towel. Shape the sweater to its finished measurements while it is still damp and allow it to dry completely before wearing.

Tips for Success

One of the most common questions with top-down sweaters is how to keep the raglan lines neat. The trick is to keep your tension consistent at the increase points. If you notice the fabric pulling or puckering at the markers, try working the increase stitches a bit more loosely.

Another thing worth mentioning is button openings. Many people prefer to add a short button band at the back neckline for newborns, who have relatively large heads in proportion to their bodies. To do this, before joining your foundation chain into a ring, work flat for 3 to 4 rows, then join and continue in the round. Add a crochet button loop and sew on a small button. This makes the sweater much easier to get on and off a newborn.

If you want to add stripes or color blocking, this construction method makes it effortless. Simply change colors at the join at the end of any round and carry the unused color loosely up the inside of the work for just a few rounds, or cut and rejoin as needed.

For sizing adjustments, remember that adding or removing stitches from your starting chain changes the neck circumference and the overall stitch count throughout the pattern. If your child has a particularly large or small head relative to their chest, you can adjust the starting chain by 4 to 6 stitches in either direction and compensate by working more or fewer increase rounds in the yoke.

Care Instructions

Always check the label of your yarn for specific care instructions. As a general rule, acrylic and acrylic blend yarns can be machine washed in cold water on a gentle cycle and tumble dried on low. Natural fibers such as cotton or wool require more care. Cotton can typically be machine washed but should be laid flat to dry to prevent stretching. Wool should be hand washed in cool water and laid flat to dry.

Frequently Asked Questions

Can I use a different weight yarn? Yes. If you use DK weight yarn (category 3), use a 4.0 or 4.5 mm hook and work a gauge swatch. Your starting chain numbers will change because DK stitches are smaller, so adjust by adding about 20 percent more stitches to each section.

What if the neckline feels too tight? Go up half a hook size just for the neckline ribbing, then switch back for the yoke. Alternatively, block the neckline aggressively while it is wet, which opens it up considerably in most yarn types.

Can I make this in single crochet instead of HDC? Absolutely. Single crochet produces a tighter, denser fabric. Use the same hook and adjust your gauge accordingly. The sweater will feel slightly stiffer but will also hold its shape very well, which some people prefer for outerwear.

My sleeve stitch count does not match. What happened? This is very common. The underarm bridging chains can shift the count slightly, and individual crocheters pick up underarm stitches differently. As long as your sleeves match each other and the circumference looks proportional, you are fine. Adjust by adding or removing a stitch or two at the underarm as needed.
