Granny Square Pattern Maker
Make a classic granny square pattern and plan a blanket from it. Choose the number of rounds, whether to work ch 1 between clusters, US or UK terms and a colour plan, and the tool draws a round-by-round chart (one symbol per stitch) and writes every round out with its stitch count. Then set how many squares across and down, how the colours move from square to square and the size of one of your squares: you get a colour plan of the whole blanket, its finished size and an estimate of the yarn for each colour. The chart and the written rounds come from the same stitch model, so they always agree. Nothing is uploaded.

Frequently asked questions
What is a granny square?
A square crocheted in the round from the centre out, made of groups (clusters) of three double crochet stitches with a chain-2 space at each corner. Each round adds one cluster to every side, so the square grows by one cluster per side per round.
How many stitches are in each round?
Round r has 4r clusters, so 12r double crochet (US) or treble crochet (UK), 4 ch-2 corners, and with ch 1 between clusters 4(r − 1) ch-1 spaces. Round 1 has 12, round 2 has 24, round 3 has 36. The table on this page lists rounds 1 to 12; our tests check every round of every preset.
Do the chart and the written rounds match?
Yes. Both are made from one stitch model, and our tests count the symbols on the chart for every round and compare them with the stitches counted back from the written instructions.
Which symbols does the chart use?
The standard crochet symbols: a T with a slash for a double crochet (US) or treble (UK), an oval for a chain, a dot for a slip stitch join and a circle for the starting ring. A key is printed under the chart.
US or UK terms?
Both. US double crochet (dc) is the UK treble (tr); chains and slip stitches are the same. Switch the terms and the chart key, the written rounds and the counts all change together.
How big will my blanket be?
Measure one finished square and enter it; the tool multiplies by the squares across and down. Joining and a border add a little, so the size is stated before them.
How much yarn do I need?
The tool adds up the stitches of each colour over every square and multiplies by the yarn per stitch you enter. It is an estimate: crochet ten stitches, pull them out and measure for your own yarn and hook, and buy a little extra for ends and joining.
Is it free?
Yes. There is no sign-up, no watermark and no limit.
Is anything uploaded?
No. The pattern is made by JavaScript in your browser. Nothing you choose is sent anywhere or saved when you close the page.
