Chunky Ribbed Crochet Cardigan Pattern Free You Can Customize for Any Size

This Crochet Ribbed Cardigan pattern makes a semi cropped cardigan with a defined V neckline, clean vertical ribbing, and a comfortable fit that still looks structured. The cardigan is worked sideways, which means you can adjust the height first, then shape the neckline and shoulder width gradually, making it easier to customize without complicated math.

Crochet Ribbed Cardigan

The ribbed band at the bottom keeps the hem neat, the sleeves are shaped to sit smoothly around the armhole, and the neck binding adds a polished finish with optional buttonholes. If you want a cardigan that works as an everyday layer, this design is versatile enough to wear open, buttoned, or slightly oversized depending on how wide you make the panels.

Materials

Medium weight yarn held double or a single heavier yarn that matches gauge
5 mm hook for the main cardigan body
4 mm hook for neckline binding and ribbing rows

How to Measure Before You Start

Height measurement for starting chain measure from the bottom hem where you want the cardigan to end up to the top of the shoulder
Shoulder width measurement from the center front edge to where you want the shoulder seam to sit
Front panel width measurement how wide you want each front panel to be from center front edge toward the side seam
Back width measurement across your back from one side seam area to the other
Armhole depth measurement from top of shoulder down to underarm
Sleeve length measurement from armpit to wrist or from shoulder to wrist depending on how you prefer sleeves

Front Panels Make 2

Front Panel Foundation and Setup

Chain the length you want for the cardigan height
Add 1 extra chain for turning
Example the tutorial uses 60 plus 1 chains for about 11 inches height
Keep the chain relaxed but even so the fabric does not pull

Band and Main Body

Ch 1 and turn if needed depending on how you start
Work sc into the second chain from the hook and continue for 10 sc total to create the bottom band
Place a stitch marker in the 10th sc if that helps you separate band from body
Switch to hdc stitches for the remaining chains
Work 1 hdc into each chain to the top edge
Turn

Increase Row for V Neck Slope

Ch 1 and turn
In the first stitch at the neckline edge work 3 hdc into the same stitch using both loops
This is the increase that creates the V neck angle
Continue across the body section with 1 hdc in blo in each stitch
When you reach the band section work 1 sc in blo in each band stitch
In the last band stitch work through both loops to keep the edge clean and stable
Turn

Band Straight and Top Increase

Ch 1 and turn
Work the band first with sc in blo across the band stitches
Continue with hdc in blo across the body stitches
In the very last stitch at the neckline edge work 3 hdc into the same stitch
This increase keeps the neckline slope consistent
Turn

Up Building the Neckline and Shoulder

Repeat the same shaping rhythm used in rows 2 and 3
Keep increases at the neckline edge only
Continue until the slanted edge reaches your shoulder width measurement
Check by folding the panel against your body from center front up toward shoulder
Once the shoulder width is reached stop increasing

Straight Shoulder Section

Continue working rows without increases
Keep the band stitches in sc blo
Keep the body stitches in hdc blo
Work until the front panel reaches your desired width
For a more open cardigan make the front panel narrower
For more coverage make it wider

Finish the First Front Panel

Fasten off leaving a long tail for seaming if you want to sew later
Make the second front panel the same size
If you want mirrored panels orient the increases so both panels slope correctly for a V neck
The easiest way is to place the first panel down and begin the second so the increase edge will become the inner neckline edge again

Back Panel Make 1

Back Panel Foundation

Chain the same number of stitches as the outer edge height of your front panels
Add 1 chain for turning

For Back Panel Body Rows

Work the same fabric pattern as the front panels but without neckline increases
Row 1 work 10 sc for the band then hdc to the top
Next rows work band stitches in sc blo and body stitches in hdc blo
Work straight rows until the back width matches the combined width of both front panels
Measure by laying the two front panels side by side then match the back panel width to that total

Finish Back Panel

Fasten off leaving a tail for seaming

Assembly

Layout Before Seaming

Lay the back panel flat
Place the two front panels on top of the back panel
Align the top edges and the shoulder areas
Make sure the neckline edges are facing inward toward the center front
Make sure the outer edges align with the back panel edges

Join Shoulder Seams

Join each front panel to the back panel at the shoulder
Use sc seam or sew with a tapestry needle
Seam only the shoulder width area
Keep seams even so the neckline sits flat

Join Side Seams and Leave Armholes

Fold the cardigan so right sides are together if you want hidden seams
Starting at the bottom hem sl st or sc seam upward along the side edges
Stop when you reach the armhole opening
Leave an armhole depth opening of about 8 inches or your preferred measurement
Repeat on the other side
Turn cardigan right side out

Sleeves Make 2

Foundation and Attachment

Attach yarn at the armpit point of the armhole opening
Chain the length you want for sleeve length
Example chain about 74 for around 18 inches depending on yarn and hook
Add 1 chain for turning

Row 1 Wrist Band and Sleeve Body

Work 12 sc to create the wrist band section
Continue with hdc stitches for the rest of the row
Attach the sleeve row to the armhole by making a sl st into the next available stitch or row edge on the armhole
This connects the sleeve to the body as you build it

Row 2 and Up Working the Sleeve Fabric

Ch 1 and turn
Work sc blo for the wrist band section
Work hdc blo for the sleeve body section
At the end of each row join to the armhole edge with a sl st
Continue building rows around the armhole opening

Sleeve Shaping Increases

To fit the armhole circumference you will add width near the armhole side
On increase rows add 1 extra stitch at the armhole side before joining
You can do this by working 2 hdc in the final stitch or by adding one extra hdc into the join area depending on how your edge looks
Alternate increase rows with regular rows until the sleeve fabric curves smoothly around the armhole
Keep checking by laying the sleeve fabric against the armhole edge as you go

Sleeve Shaping Decreases

When you reach the top center of the armhole begin decreasing
Skip 1 stitch at the armhole side at the start of the row or at the end of the row depending on which side is joining
Keep the wrist band section consistent in width
Continue decreasing gradually until the sleeve section is complete and fits the remaining armhole edge

Close Sleeve Seam

Fold the sleeve so right sides are together
Sl st or sew the sleeve seam from wrist to armpit
Turn right side out
Repeat for the second sleeve

Neck Binding Ribbing and Buttons

Base Binding Row

Switch to the 4 mm hook
Attach yarn at the bottom of one front edge
Work hdc evenly up the front edge toward the neckline
Continue around the neck and down the other front edge
At the V point work 3 hdc in one stitch to keep the point defined
Along the back neckline work 1 hdc per row edge so the neck does not flare
Continue until you return to the start
Join with a sl st

Ribbing Rows for a Professional Finish

Ch 1 and turn
Work fp hdc around the next stitch then bp hdc around the next stitch
Repeat fp hdc and bp hdc across to create ribbing
Join and turn at the end of each row
Continue for several rows until the neckline looks sturdy and neat

Buttonholes

Decide button placement and mark with stitch markers on one side of the front edge
Work ribbing until you reach a marked buttonhole position
Ch 4 then skip 2 stitches
Continue ribbing across
Repeat for each buttonhole placement on that same row
On the next row work hdc stitches into each ch 4 space to secure and size the hole
Continue ribbing rows if you want a thicker band

Finishing

Weave in all ends securely
Sew buttons onto the opposite front edge aligned with buttonholes
Try the cardigan on and adjust button placement if needed
Block lightly if your yarn benefits from it so the ribbing lays flat and the neckline sits cleanly

Customization Tips

For longer cardigan add more chains at the beginning to increase height
For a less cropped style increase the height measurement and chain longer
For a looser fit add more straight rows on front and back panels for extra width
For tighter sleeves reduce sleeve chain length slightly or reduce increase frequency
For a deeper V neck continue increase rows longer before stopping at the shoulder point
For a higher neckline stop increases earlier and begin straight rows sooner

Troubleshooting

If the neckline edge ruffles reduce how often you do the 3 hdc increase or tighten your turning tension
If the cardigan feels stiff use a larger hook or a softer yarn
If the hem curls add one extra row of sc at the band or block the finished piece
If armholes feel tight increase the armhole opening depth during side seam assembly
If sleeves feel too wide reduce increase rows and start decreasing earlier
