How to crochet a granny square (2026)

Overview

A classic granny square is one of the most useful beginner crochet motifs because it teaches the core skills of working in the round, making corners, joining rounds and building fabric evenly. Although patterns vary, the traditional version is made from clusters of stitches separated by chain spaces, with each new round adding more clusters along the sides and one corner space at each corner. That structure is what turns a circle-like centre into a square. For a first attempt, use smooth, light-coloured yarn and a hook size recommended on the yarn label or pattern, because textured or very dark yarn makes it harder to see your stitches. You should already know how to make a slip knot, chain, join with a slip stitch and work the main crochet stitch your chosen granny square pattern uses. Read the whole pattern before you start so you know where corners happen and how each round begins and ends. The most important practical points are to identify corner spaces correctly, keep your stitch tension even, and count as you go. If your square ripples, your tension is probably too loose or you have added too many stitches; if it cups, your tension may be tight or you may have missed spaces. Once you understand the repeating corner-and-side structure, granny squares become quick and flexible to make.

Who this is for

Beginners who know the very basics of crochet, and anyone who wants to make blankets, bags, cushions or patchwork-style projects from small motifs.

What you’ll need

• Yarn suitable for crochet, ideally smooth and light coloured for learning
• Crochet hook in the size recommended on the yarn label or in your pattern
• Scissors
• Yarn needle for weaving in ends
• A written granny square pattern or trusted tutorial
• Basic crochet knowledge: slip knot, chain, slip stitch and the main stitch used in the pattern

Before you start

Check whether your pattern uses UK or US crochet terms, because the same stitch names can mean different things. Look at the yarn band for a suggested hook size if your pattern does not specify one, and make sure you can recognise chain spaces, stitch groups and corners before beginning.

Step-by-step

1. 1

   Choose a simple granny square pattern and gather materials

   Pick a basic granny square pattern from a trusted source and read it all the way through. Set out your yarn, hook, scissors and yarn needle, and confirm whether the pattern uses UK or US stitch terminology.

   Why: Granny squares are simple once the structure is clear, but using the wrong terminology or starting without understanding the repeat is a common reason beginners get stuck.

2. 2

   Make the centre ring

   Begin with a slip knot and create the centre as your pattern instructs, usually by forming a small ring from chains joined together or by using another approved adjustable centre method if the pattern allows it.

   Why: The centre ring is the anchor for the first round. If it is twisted, loose in the wrong way or hard to work into, the whole square can look uneven from the start.

3. 3

   Work the first round into the centre

   Crochet the first set of stitch groups into the centre ring, placing the chain spaces or corner spaces exactly where the pattern tells you. Join the round neatly at the correct point rather than guessing where it ends.

   Why: This first round establishes the four corners. If the corner spaces are misplaced now, later rounds will not form a proper square.

4. 4

   Start the next round in the correct place

   Move to the next starting point as your pattern directs, often by joining and then moving across with slip stitches or starting directly in a corner space. Begin the new round with the required starting chains or substitute starting method given in the pattern.

   Why: Starting in the right place keeps the round balanced and helps the join blend in. It also ensures the first side and first corner are the correct length.

5. 5

   Build each side and corner in sequence

   Work along each side by placing stitch groups into the side spaces from the previous round, and place the corner instructions into each corner space. Repeat this around the square, checking that each side matches the others before joining the round.

   Why: A granny square grows because each corner creates room for the turn while the side groups fill out the edges. Missing a side space or adding an extra group quickly distorts the shape.

6. 6

   Repeat rounds until the square is the size you want

   Continue adding rounds using the same side-and-corner pattern. Stop after the number of rounds your project needs, or compare it with your intended finished size if making multiple matching squares.

   Why: Granny squares are modular, so consistency matters. Matching round counts and tension across squares makes joining much easier later.

7. 7

   Fasten off and weave in the ends

   Cut the yarn leaving a tail long enough to weave in securely, pull it through to fasten off, then use a yarn needle to thread the ends back through the stitches on the reverse side.

   Why: Properly woven ends stop the square unravelling in use or after washing. Simply trimming tails short without securing them can cause the work to come apart.

8. 8

   Block if needed

   If the square looks slightly uneven, follow the yarn manufacturer's care guidance and your preferred blocking method to shape it so the corners are square and the sides lie flat.

   Why: Blocking helps even out tension differences and gives a cleaner shape, which is especially helpful before joining multiple squares together.

Why this works

A granny square works because the corner spaces add turning room at four fixed points while the stitch groups along each side expand the edges evenly. Repeating that structure round after round keeps the fabric square rather than circular.

Common mistakes to avoid

• Confusing UK and US crochet terms and using the wrong stitch
• Putting side groups into stitches instead of the chain spaces specified by the pattern
• Missing a corner space or working the wrong corner instruction
• Joining each round in the wrong place so the square gradually twists
• Using very tight or very loose tension, which makes the square cup or ripple
• Failing to count sides and corners at the end of each round

Troubleshooting

Compare your options

Alternatives

• Use a solid granny square pattern if you want fewer holes
• Start with a large practice swatch worked flat first if you do not yet understand stitch groups and chain spaces
• Try a hexagon or circle motif once you are comfortable working in rounds

Pro tips

• Use a stitch marker to mark the first corner of each round until you can recognise the pattern easily.
• Choose smooth yarn rather than fluffy novelty yarn for your first square.
• Count the number of side groups after every round; it is easier to fix one mistake immediately than several rounds later.
• If making many squares, keep notes on hook size, yarn and round count so they all match.
• Weave in ends as you go if you are changing colours often.

Safety notes

• Keep hooks, scissors and yarn needles away from small children and pets.
• Take breaks if your hands or wrists become sore.
• Use sharp scissors carefully and store them closed when not in use.

Cost considerations

Granny squares can be economical because they work well with leftover yarn, but using many colours increases the time spent weaving in ends. Better-quality yarn can improve durability and ease of care, so check the yarn label before buying for a large project.
