Why You’ll Love This Crochet T-Rex Pattern
Before we get into the nitty-gritty of stitches and rows, let’s talk about why this pattern is worth your time. Amigurumi dinosaurs have been trending in the crochet community for good reason — they’re versatile, gender-neutral, and universally beloved. This particular T-Rex design hits a sweet spot between beginner-friendly and satisfying to make. If you’ve crocheted a few amigurumi pieces before, you’ll breeze right through. If you’re relatively new to the craft but comfortable with single crochets and magic rings, you’ll still be able to tackle this with confidence.
The finished T-Rex stands approximately 7 to 8 inches tall when stuffed firmly, making it a perfect handheld size for toddlers and young children. All pieces are crocheted separately and sewn together, which keeps each individual component manageable and stress-free. There are no complicated colorwork sections, no specialty stitches that require hours of tutorials, and no confusing construction methods. It’s clean, simple, and endlessly charming.
Materials You’ll Need
Getting your supplies together before you start is always a smart move. Here’s a full list of everything you’ll need for this project.
Yarn: Worsted weight yarn (size 4) in your chosen main color. For this pattern, a classic green works beautifully — think something in the range of forest green, lime green, or even a fun teal. You’ll also need a small amount of a contrasting color for the belly. White or cream works wonderfully for this. Optional: a tiny bit of black or dark brown for any color details you want to add.
Hook: A 3.5mm (US E/4) crochet hook. This size works well with worsted weight yarn to create a tightly woven fabric that holds its shape and keeps the stuffing securely inside.
Stuffing: Polyester fiberfill stuffing. Use a generous amount for a nicely rounded, firm body. Don’t be shy with the stuffing — a well-stuffed amigurumi always looks more polished.
Safety eyes: Two 12mm black safety eyes. These give your T-Rex that classic, endearing amigurumi expression. If you’re making this for a child under three, swap safety eyes for embroidered eyes using black yarn for safety reasons.
Yarn needle: For sewing pieces together and weaving in ends.
Scissors: A sharp pair for clean cuts.
Stitch markers: These are your best friend in amigurumi. Use them to mark the beginning of each round so you never lose your place.
Optional: Pink or red embroidery floss for a small smile or rosy cheeks, felt for tiny teeth, and pins for positioning pieces before sewing.
Abbreviations and Stitches Used
This pattern uses standard US crochet terminology. Here’s a quick reference guide for all the abbreviations you’ll encounter.
MR — Magic ring
ch — Chain
sl st — Slip stitch
sc — Single crochet
inc — Increase (2 single crochets in the same stitch)
dec — Invisible decrease (insert hook through front loops of next two stitches, yarn over and pull through, yarn over and pull through both loops)
BLO — Back loop only
FLO — Front loop only
st(s) — Stitch(es)
rnd — Round
rep — Repeat
Gauge
Gauge is not critical for amigurumi, but for reference: 14 stitches and 16 rows in single crochet equals approximately 4 inches with a 3.5mm hook and worsted weight yarn. Your finished T-Rex may be slightly larger or smaller depending on your tension, which is completely fine. Just ensure your stitches are tight enough that the stuffing doesn’t show through.
The Pattern
Body
The body is worked from the bottom up in continuous rounds.
Using main color, make a magic ring.
Rnd 1: 6 sc in MR (6 sts)
Rnd 2: inc in each st around (12 sts)
Rnd 3: (sc 1, inc) rep around (18 sts)
Rnd 4: (sc 2, inc) rep around (24 sts)
Rnd 5: (sc 3, inc) rep around (30 sts)
Rnd 6: (sc 4, inc) rep around (36 sts)
Rnd 7: (sc 5, inc) rep around (42 sts)
Rnd 8-14: sc in each st around (42 sts) — work 7 rounds even
Rnd 15: (sc 5, dec) rep around (36 sts)

Rnd 17: (sc 4, dec) rep around (30 sts)
Rnd 18: sc in each st around (30 sts)
Rnd 19: (sc 3, dec) rep around (24 sts)
At this point, insert your safety eyes between rounds 10 and 11, approximately 8 stitches apart. Begin stuffing the body firmly.
Rnd 20: (sc 2, dec) rep around (18 sts)
Rnd 21: (sc 1, dec) rep around (12 sts)
Rnd 22: dec around (6 sts)
Fasten off, leaving a short tail. Use your yarn needle to close the remaining 6 stitches and weave in the end. Set the body aside.
Belly Patch
The belly patch adds a lovely detail and breaks up the color beautifully.
Using contrast color, make a magic ring.
Rnd 1: 6 sc in MR (6 sts)
Rnd 2: inc in each st around (12 sts)
Rnd 3: (sc 1, inc) rep around (18 sts)
Rnd 4: (sc 2, inc) rep around (24 sts)
Rnd 5: sc in each st around (24 sts)
Fasten off, leaving a long tail for sewing. Flatten slightly and pin to the front center of the body. Sew neatly around the edges using your yarn needle. Weave in the end.
Head
The head is crocheted similarly to the body but with a slightly different shaping to give it that classic T-Rex big-headed look.
Using main color, make a magic ring.
Rnd 1: 6 sc in MR (6 sts)
Rnd 2: inc in each st around (12 sts)
Rnd 3: (sc 1, inc) rep around (18 sts)
Rnd 4: (sc 2, inc) rep around (24 sts)

Stuff the head firmly before closing.
Rnd 17: (sc 1, dec) rep around (12 sts)
Rnd 18: dec around (6 sts)
Fasten off and close as with the body. Set aside.
Snout
The snout gives the T-Rex his characteristic expression.
Using main color, make a magic ring.
Rnd 1: 6 sc in MR (6 sts)
Rnd 2: inc in each st around (12 sts)
Rnd 3: (sc 1, inc) rep around (18 sts)
Rnd 4-5: sc in each st around (18 sts)
Fasten off, leaving a long tail. Lightly stuff and pin to the front lower half of the head. Sew in place. If you’d like to add tiny felt teeth, cut small white triangles and tuck them under the snout edge before sewing it closed all the way around. You can also embroider a small curved smile using black yarn.
Legs (Make 2)
Using main color, make a magic ring.
Rnd 1: 6 sc in MR (6 sts)
Rnd 2: inc in each st around (12 sts)
Rnd 3: sc in BLO around (12 sts) — this creates the foot ridge
Rnd 4-10: sc in each st around (12 sts) — work 7 rounds even
Stuff lightly. Fasten off, leaving a long tail for sewing. Flatten the top of the leg and sew closed with a few stitches before attaching to the body. Position the legs at the bottom sides of the body, approximately 4 stitches apart, and sew securely.
Arms (Make 2)
T-Rex arms are famously tiny and adorable — these are no exception.
Using main color, make a magic ring.
Rnd 1: 6 sc in MR (6 sts)
Rnd 2: inc in each st around (12 sts)
Rnd 3-6: sc in each st around (12 sts)
Rnd 7: dec 3 times, sc 6 (9 sts)
Do not stuff (or stuff very lightly). Fasten off, leaving a long tail. Flatten and sew to the sides of the body near the neck, angled slightly downward for that classic T-Rex pose.
Tail
The tail is what really completes the silhouette and gives your amigurumi that unmistakable dinosaur shape.
Using main color, make a magic ring.
Rnd 1: 4 sc in MR (4 sts)
Rnd 2: (sc 1, inc) rep around (6 sts)
Rnd 3: sc in each st around (6 sts)
Rnd 4: (sc 2, inc) rep around (8 sts)
Rnd 5: sc in each st around (8 sts)
Rnd 6: (sc 3, inc) rep around (10 sts)
Rnd 7: sc in each st around (10 sts)
Rnd 8: (sc 4, inc) rep around (12 sts)
Rnd 9-11: sc in each st around (12 sts)
Fasten off, leaving a long tail. Stuff lightly and sew to the back lower center of the body. The tail should angle slightly downward and outward for balance.
Dorsal Spines (Optional but Highly Recommended)
These little spikes running down the back of your T-Rex add so much personality and are incredibly quick to make.
Make 5 spines in varying sizes for a tapered effect. For each spine:
Using main color (or a contrasting color if you prefer), make a magic ring.
Small spine: 3 sc in MR, sl st to join, fasten off with tail for sewing.
Medium spine: 4 sc in MR, sc 1 rnd even, sl st to join, fasten off with tail.
Large spine: 6 sc in MR, sc 1 rnd even, sl st to join, fasten off with tail.
Don’t stuff the spines — just flatten them into a little petal or triangle shape. Sew them along the center back seam of the body, starting with the largest near the neck and tapering down to the smallest toward the tail.
Assembly
Assembly is where everything comes together, and it’s genuinely one of the most satisfying parts of any amigurumi project. Here’s the order that works best.
Start by attaching the snout to the head if you haven’t already. Once the snout is secure, sew the head to the top of the body. Position it so the face angles forward slightly rather than straight up — this gives your T-Rex a more natural, alert expression. Use plenty of yarn and stitch through both pieces several times for a sturdy join.
Next, sew on the dorsal spines along the top center of the body in a straight line from just behind the head to just before the tail attachment point. Then sew on the tail at the back base of the body.
Attach the legs last, positioning them evenly on the bottom of the body so the T-Rex can stand upright. Test the balance before sewing them permanently — shifting a leg forward or backward by just a stitch or two can make the difference between a dinosaur that stands proudly and one that tips over. Sew the tiny arms to the upper front sides of the body.
Once everything is attached, take a moment to tidy up any visible seams with your yarn needle, pulling yarn tails inward and weaving them in securely. If you’d like to add a smile, now is the time — a simple curved line of embroidery floss in dark brown or black stitched just below the snout looks absolutely precious.
Tips for the Best Results
Tension matters more than you might think in amigurumi. If your stitches are too loose, stuffing will poke through and the finished piece will look lumpy. If you find this happening, try dropping down to a 3.25mm hook.
When stuffing each piece, use small amounts at a time and poke them into position with the eraser end of a pencil or a dedicated stuffing tool. This helps you get stuffing into narrow parts like the tail and snout without distorting the shape.
For clean, invisible seams when sewing pieces together, use the mattress stitch. Insert your needle under the loops of one piece, then under the corresponding loops of the other, alternating back and forth. Pull gently to tighten, and the seam almost disappears.
If you’re gifting this T-Rex to a baby or very young child, use embroidered eyes instead of safety eyes, secure all yarn ends triple-knotted inside the piece, and consider omitting the felt teeth. Safety always comes first with toys for little ones.
Color Variations to Try
One of the best things about making your own amigurumi is the freedom to make it however you like. While green is the classic choice, there’s no rule that says your T-Rex has to be any particular color. A soft lilac T-Rex with a pale pink belly makes for a beautifully unexpected gift. A deep teal version with a cream belly looks incredibly sophisticated. If you want something wild and fun, go for a rainbow effect by switching colors every few rounds on the body. A speckled or tweed yarn creates a lovely textured look that mimics the appearance of scales.
For the dorsal spines, using a contrast color creates a striking look — try orange spines on a green body, or gold spines on a brown body. The possibilities really are endless, and each version you make will feel like a completely new character.
