C2C & Tapestry Pixel Grid Generator + Written Row Exporter
Paint a pixel chart with your finger, then let the tool write the pattern for you: diagonal C2C rows with their increase and decrease phases, right-side and wrong-side tapestry rows, or filet blocks and spaces. Every row has a checkbox to tick off while you crochet, and the yarn table tells you how many meters, grams and skeins of each color to buy.

Pick a brush color, then tap or drag across the grid. Thick lines mark every 10 cells, counted from the bottom-left corner.

Start in the bottom-right corner: ch 6, dc in 4th ch from hook and in the next 2 ch (1 tile). Odd rows are listed from the lower-left end of the diagonal to the upper-right end, even rows the other way.

Our assumptions: cell size from the CYC single crochet gauge of the yarn weight (C2C tile = 3 stitch widths square; tapestry sc row = stitch width ÷ 1.1; filet square = 3 stitch widths × one dc row) until you enter your own; yarn = calibrated model of our yarn calculator (area × 0.82 × √density × stitch factor: dc 1.0, sc 1.3) + 10 % for color changes and tails; tapestry adds the strand carried between the first and last stitch of each color in a row; a filet space uses 50 % of the yarn of a block. Reading conventions are stated above the written rows; check them against your pattern.
How it works: the math behind the tool
How a C2C blanket is calculated. Corner-to-corner crochet builds the fabric from small tiles, each made of a ch 3 and 3 double crochets, worked along diagonals. On a chart of W columns and H rows there are W + H − 1 diagonals: the first holds one tile, each following row adds one tile while it grows from the corner (increase phase), a rectangle then keeps the same count by increasing at one edge and decreasing at the other, and the last rows lose one tile each (decrease phase). The finished size is simply columns × tile width by rows × tile height, so a 40 × 50 baby blanket with 2.4 cm tiles measures about 96 × 120 cm. Because tiles are square, measure ten tiles of your swatch and divide by ten instead of trusting a generic gauge.
How to read a tapestry chart. In tapestry (or intarsia) crochet each cell is one single crochet. Rows are numbered from the bottom of the chart; when you work flat and right-handed, odd rows (right side) are read from right to left and even rows (wrong side) from left to right, so the written instructions reverse every other row for you. Colors that are not in use are carried inside the stitches, which keeps the back tidy but uses extra yarn and makes the fabric thicker. Single crochet stitches are wider than they are tall, so the editor draws the cells with the real proportions of your gauge: a motif that looks round on screen will look round on the blanket.
Meters per color = cells × cell width × cell height ÷ 100 × 0.82 × √density × stitch factor × 1.10 · C2C rows = columns + rows − 1
Yarn per color. The tool counts the tiles or stitches of each color and multiplies their area by the calibrated model of our yarn calculator (meters = area ÷ 100 × 0.82 × √(meters per 100 g) × stitch factor), then adds 10 % for color changes and woven-in tails. Tapestry also adds the carried strand between the first and last stitch of each color in a row, and a filet space counts as half a block. Each color is rounded up to whole skeins separately, because you buy every shade on its own. These are estimates for planning the order; buy all skeins of a color from the same dye lot.

Frequently asked questions
How many rows does a C2C blanket have?
Columns + rows − 1 diagonal rows. A 25 × 25 square has 49 rows: 25 increase rows (from 1 to 25 tiles) and 24 decrease rows. A 40 × 50 rectangle has 89 rows, including a middle section where you increase at one edge and decrease at the other.
How much yarn do I need for a C2C blanket?
It depends on the tile size and the yarn. As a planning figure, the generator multiplies the tiles of each color by the area of one tile and by our calibrated yarn model, adds 10 % for color changes and rounds each color up to whole skeins. Type the real size of your tiles and the yarn you will use for the closest estimate.
Do I read a tapestry crochet chart from left to right?
Only on the wrong-side rows. Start at the bottom right of the chart: odd rows (right side) are read from right to left and even rows (wrong side) from left to right when you work flat. The written pattern already lists every row in working order, so you can follow the text instead of the chart.
What is the difference between C2C, tapestry and filet crochet?
C2C works square tiles along diagonals and is ideal for pixel blankets with few color changes per row. Tapestry works single crochet in straight rows and gives the sharpest images, with carried strands inside. Filet uses a single color and draws the picture with filled blocks and open mesh spaces.
