Classic Granny Square

By the DoubleCrochet Team | Last Updated: November 2026 | Skill Level: Beginner

A 5-round classic granny square measures about 5" × 5" (12.5 × 12.5 cm) (estimate) and uses 26 to 32 yards (24 to 29 m) (estimate) of Category 4 medium worsted-weight yarn with a 5.0 mm (H-8) crochet hook. Worked from the center outward in groups of 3 double crochets (3-dc granny clusters) separated by ch-1 side spaces and (3 dc, ch 2, 3 dc) corner shells, every round adds exactly 4 clusters (12 double crochet stitches) to the square.

Because your hook goes directly into the open chain spaces between clusters rather than into tight individual stitch loops, the classic granny square is one of the fastest, most relaxing motifs in crochet. You can stop after 3 rounds for a coaster, join 8 five-round squares into a granny square tote bag, or keep adding rounds infinitely to crochet a giant single-square throw blanket.

Worked entirely into open chain spaces with 3-dc clusters, a 5-round classic granny square takes less than 15 minutes and uses under 32 yards of worsted yarn.

Materials & Tools Needed

• Yarn: Category 4 Medium Worsted-Weight Yarn (smooth acrylic, 100% cotton, or superwash wool in 1 to 5 contrasting colors). Want to test how your stash shades look together before cutting yarn? Use our interactive tool to plan colours.
• Crochet Hook: 5.0 mm (US H-8) for blankets, throws, and wearables (or downsize to a 4.5 mm / US 7 hook if making firm squares for bags and coasters)
• Notions: Sharp scissors, blunt metal tapestry needle for weaving in ends, and blocking pins + foam mat (or a wooden granny square blocking pegboard)

Abbreviations & Stitches Used (US Terms)

This pattern uses US crochet terminology. (In UK terms, a US double crochet (dc) is called a treble crochet (tr).)

Written Pattern: 5-Round Classic Granny Square

Foundation Ring (Choose Your Preferred Starter)

• Option A — Chain-4 Ring (Most Secure for Blankets & Bags): Ch 4, insert your hook into the first chain made, and join with a sl st to form a small ring.
• Option B — Magic Ring (Zero Center Hole): Form an adjustable magic loop and work Round 1 inside the ring, then pull the tail tight and weave it back and forth in two directions so the center can never loosen in the wash.

Round 1: Building the First 4 Corners (12 dc)

1. Ch 3 (counts as your first dc here and throughout the pattern).
2. Work 2 dc into the center ring. ( Together with the starting ch-3, this forms your first 3-dc granny cluster.)
3. Ch 2 (first corner space made), then work 3 dc into the center ring (second cluster made).
4. Repeat [Ch 2, work 3 dc into the center ring] 2 more times (for a total of 4 clusters around the ring).
5. Ch 2 (fourth corner space made), and join with a sl st into the top (3rd chain) of the beginning ch-3.

• Round 1 Count: 4 granny clusters (12 dc) separated by four ch-2 corner spaces.

How to Start Round 2 (3 Methods to Choose From)

Before beginning Round 2, choose how you want to position your hook in a corner ch-2 space:

1. Method 1 — Slip-Stitch to Corner (Single-Color Square, Same Side): Keep your yarn attached, work 1 sl st into the top of the next 2 dc stitches of the cluster to your left, and work 1 sl st directly into the ch-2 corner space. You are now inside the corner and ready to ch 3.
2. Method 2 — Turn Your Work (Single-Color Square, Zero Twist): After joining Round 1 with a sl st, turn your square over like the page of a book so the Wrong Side (WS) faces you, sl st directly backward into the ch-2 corner space you just finished, and ch 3. Turning after every round completely prevents large squares from twisting!
3. Method 3 — Changing Colors in Any Corner: Fasten off Round 1. Insert your hook into any ch-2 corner space and either pull up a loop of the new color and ch 3, or start with a seamless stitch using our tutorial on standing dc colour joins (which eliminates the ch-3 bump entirely).

Round 2:Expanding the 4 Corners (24 dc)

1. With your hook inside a ch-2 corner space, ch 3 (counts as 1 dc), then work (2 dc, ch 2, 3 dc) into that same ch-2 corner space. (First corner shell made.)
2. *Ch 1 (side space), skip the 3-dc cluster below, and work (3 dc, ch 2, 3 dc) into the next ch-2 corner space.
3. Repeat from * 2 more times (until all 4 corners have a (3 dc, ch 2, 3 dc) shell).
4. Ch 1, and join with a sl st into the top of the beginning ch-3.

• Round 2 Count: 8 granny clusters (24 dc), four ch-2 corner spaces, and four ch-1 side spaces (1 side space per edge).

Round 3: Adding the First Side Clusters (36 dc)

1. Move into the corner ch-2 space (or join a new color in any ch-2 corner space). Ch 3 (counts as 1 dc), and work (2 dc, ch 2, 3 dc) into the same corner space.
2. *Ch 1, work 3 dc into the next ch-1 side space, ch 1, and work (3 dc, ch 2, 3 dc) into the next ch-2 corner space.
3. Repeat from * 2 more times.
4. Ch 1, work 3 dc into the last ch-1 side space, ch 1, and join with a sl st into the top of the beginning ch-3.

• Round 3 Count: 12 granny clusters (36 dc) — 2 corner clusters + 1 side cluster along each of the 4 edges, separated by ch-1 side spaces.

Round 4: Two Side Clusters Per Edge (48 dc)

1. Move into or join yarn in a ch-2 corner space. Ch 3 (counts as 1 dc), and work (2 dc, ch 2, 3 dc) into the same corner space.
2. *Ch 1, [work 3 dc in next ch-1 side space, ch 1] twice, then work (3 dc, ch 2, 3 dc) into the next ch-2 corner space.
3. Repeat from * 2 more times.
4. Ch 1, [work 3 dc in next ch-1 side space, ch 1] twice, and join with a sl st into the top of the beginning ch-3.

• Round 4 Count: 16 granny clusters (48 dc) — 2 corner clusters + 2 side clusters along each of the 4 edges.

Round 5: Three Side Clusters Per Edge (60 dc)

1. Move into or join yarn in a ch-2 corner space. Ch 3 (counts as 1 dc), and work (2 dc, ch 2, 3 dc) into the same corner space.
2. *Ch 1, [work 3 dc in next ch-1 side space, ch 1] 3 times, then work (3 dc, ch 2, 3 dc) into the next ch-2 corner space.
3. Repeat from * 2 more times.
4. Ch 1, [work 3 dc in next ch-1 side space, ch 1] 3 times, and join with a sl st into the top of the beginning ch-3.
5. Fasten off, leaving a 6-inch tail, and weave in all ends securely on the Wrong Side.

• Round 5 Count: 20 granny clusters (60 dc) — 2 corner clusters + 3 side clusters along each of the 4 edges (15 dc + 3 ch-1 spaces per edge between corners).

Round-by-Round Stitch, Size & Yardage Formula (Rounds 1 to 8)

Want to keep crocheting past Round 5? Every additional round simply works (3 dc, ch 2, 3 dc) in each of the 4 corners and 3 dc in every ch-1 side space around. Use this reference table for Category 4 worsted yarn and a 5.0 mm hook:

Troubleshooting: How to Stop Granny Squares from Twisting or Waving

1. The "Granny Vortex Twist" (Why Large Squares Skew Like a Pinwheel)

Every crochet stitch has a natural slight anatomical lean toward your dominant hand. When you crochet 5, 8, or 20 rounds exclusively with the Right Side (RS) facing you, each round's clusters sit slightly to the left of the clusters below, causing the center of the square to swirl like a pinwheel.

• The Fix: Turn your work over at the end of every single round (work Round 1 on RS, Round 2 on WS, Round 3 on RS, and so on). Because the Wrong Side of a granny cluster looks almost identical to the Right Side, alternating directions keeps the diagonal corner lines laser-straight even on a 50-round blanket!

2. Wavy or Ruffling Outer Edges (Ch 1 vs. Ch 0 on Sides)

If your square's outer edges ripple or feel overly floppy, your ch 1 side spaces are adding too much width for your tension.

• The Fix: Eliminate the ch 1 between clusters along the straight sides (ch 0 on sides)—only chain at the four corners (ch 2). Working 3 dc directly into the space between previous clusters without chaining 1 creates a tighter, flatter, modern granny square with smaller holes.

3. Rounded or Cupping Corners (Ch 2 vs. Ch 3 in Corners)

If your square looks more like a circle with rounded corners or curls up like a bowl:

• The Fix: Increase your corner chain space from ch 2 to ch 3 (working (3 dc, ch 3, 3 dc) in all 4 corners). That extra corner chain gives the 90-degree turn room to lie flat and creates crisp, pointed corners that are easy to pin during blocking.

How to Block & Join Granny Squares for Blankets and Bags

1. Blocking Your Squares to Identical Dimensions

Even small tension changes between yarn colors can make one square 4.75" and the next 5.25". Blocking equalizes every motif before seaming:

• Foam Mat + T-Pins: Pin all 4 ch-2 corners to a 5" × 5" grid square on a foam blocking mat, mist with water (for cotton/wool) or hover a garment steamer 2 inches above the surface (for acrylic—never touch a hot iron to acrylic!), and let dry completely.
• Wooden Blocking Pegboard: Insert 4 stainless steel or brass rods into the 5" × 5" corner holes of a pegboard and slide up to 8 damp squares onto the rods at once so the entire stack dries to the exact same size.

2. How Many 5-Round (5" × 5") Squares Do I Need for a Project?

Once your squares are blocked, join them using the Whipstitch (BLO), Mattress Stitch, Flat Slip-Stitch Join, or Join-As-You-Go (JAYG) method. Use this chart to plan your project—or enter custom square measurements into our calculator to find out how many squares for a blanket:

Creative Variations on the Classic Granny Square

1. The Seamless Corner Join (Ch 1 + Hdc): If you are crocheting a single-color square and want to avoid slip-stitching across the 3 stitches of the first cluster at the start of every round, replace the final ch 2 corner at the end of the round with ch 1, then work 1 hdc into the top of the beginning ch-3. The top of that half double crochet lands your hook right in the middle of the corner space!
2. Continuous Giant Granny Square Blanket: Instead of sewing 80 small squares together, keep working the exact Round 5 formula ((3 dc, ch 2, 3 dc) in corners, 3 dc in each side space, turning after every round) for 36 to 45 rounds to create a seamless square throw blanket with zero joining seams.
3. 2-Color Diagonal Half-and-Half Square: Change colors inside two opposite ch-2 corner spaces (Corner 1 and Corner 3) on every round, carrying the unused yarn strand loosely inside the clusters or dropping and picking it up as you turn each round, to split the square into two crisp diagonal triangles.
