What You Get from One Photo
This is the chart ArtPatt made from the photo above: 60 ร 60 C2C chart in 12 colors.

Yarn colors matched
Each color in the picture is matched to a yarn shade and listed in the legend.
Written rows, not just a grid
Every row is written out as color runs, so you can work from the list instead of counting squares.
Balls counted per color
Stitch counts are turned into how much yarn each color needs.

From Chart to Finished C2C
The same few squares, as they sit on the chart and as they look once worked.
On the chart
- One square, one color, one symbol
- Rows and columns are numbered in the PDF
Worked corner to corner
- Each square of the graph is one tile of three double crochets
- Rows run on the diagonal, growing then shrinking
- Tiles come out close to square, so the graph is one square per tile
How it works
Upload Your Photo
Any image โ portraits, landscapes, geometric designs, pixel art โ straight from your phone or computer. Bold designs with clear color blocks work best for C2C because each tile is larger than a SC stitch.
Select DC Stitch Type
Choose Double Crochet (C2C) in the stitch selector so each square of the graph is one tile. Set the width to 40โ80 squares depending on your target blanket size.
Enable Dithering + Confetti Reduction
Dithering creates a beautiful stippled effect in C2C that simulates gradients. Set confetti to Heavy โ isolated C2C squares look particularly bad and waste yarn on cuts and joins.

Built for C2C Crochet
C2C has different constraints than SC work โ tile size, diagonal construction, and yarn consumption all differ.
DC Cluster Aspect Ratio
A C2C tile โ three double crochets and a chain-3 space โ comes out close to square, which is why C2C is charted on a plain square graph: one square, one tile. That makes C2C graphs easy to read and to count on the diagonal.
Confetti Elimination
An isolated single-square color change in C2C means cutting yarn, joining new color for one tile, and weaving in two ends. At a large DC scale, these isolated squares are visually obvious too. Heavy confetti reduction merges isolated tiles with surrounding colors โ cleaner fabric and fewer ends to weave in.
Dithering for C2C Gradients
C2C tiles are physically larger than SC stitches โ typically 2.5-3cm each. At normal viewing distance, adjacent tiles blend together. This makes Floyd-Steinberg dithering exceptionally effective: scattered tiles read as smooth color transitions and gradients, giving a tapestry-like quality with fewer colors.
Accurate DC Yarn Estimates
DC uses ~19cm of yarn per stitch โ significantly more than SC (12cm) because of the extra yarn wraps. C2C also has diagonal construction overhead. ArtPatt calculates per-color yarn consumption using DC rates, fragmentation overhead for scattered colors, and adds a 15% waste buffer. Know exactly how many skeins to buy before you start.
Real Blanket Dimensions
Enter your gauge (DC squares per 10cm) and the generator shows finished width and height for any grid size. Plan your blanket size before generating. A standard throw at 3cm per C2C square needs about 60 squares wide ร 80 squares tall. The generator updates dimensions live as you drag the slider.
Color Swapping to Match Your Stash
The algorithmically chosen colors may not match what you have at home. Click any color in the palette to replace it from our searchable 120+ yarn database. Merge two similar colors to cut down on the number of bobbins per row. Preview updates instantly so you can see the effect before downloading.
C2C Crochet: Sizes, Yarn, and Pattern Tips
C2C (corner-to-corner) crochet starts with a single double crochet cluster at one corner and expands diagonally until reaching the center, then decreases back to a single cluster at the opposite corner. Each diagonal 'row' adds one square to the right edge and one to the top edge during the increase phase. This diagonal construction means your chart โ which ArtPatt displays as a flat rectangle โ maps to a diagonal working order.
For blanket sizing: at a standard DC gauge of roughly 10 C2C squares per 10cm, a 60-square-wide blanket = 60cm wide. Most C2C squares are slightly larger โ 2.5-3cm โ so 60 squares โ 150-180cm (60-70in). A twin-size blanket needs roughly 80ร100 squares. Baby blankets work well at 40ร50 squares. The generator's dimensions calculator removes all the guesswork.
Yarn for C2C: DC stitch type uses about 19cm of yarn per stitch, compared to 12cm for SC. A 60ร80 square C2C blanket has 4,800 tiles โ at roughly 6 DC per cluster, that's 28,800 stitches ร 19cm = 5,472 meters total. At 200m per skein, that's 28 skeins across all colors. Per-color breakdown depends on your image โ the generator calculates each one separately.
C2C vs SC Graphghan: Which Should You Choose?
Choose C2C if: you want a large blanket quickly (DC is faster than SC per square inch), your image has bold shapes and clear color blocks (low detail works well at C2C scale), or you want the distinctive raised-square texture that C2C produces. C2C works especially well for geometric designs, simple portraits, and bold graphics.
Choose SC graphghan if: you want maximum image detail (SC has more pixels per cm), you're working a portrait with fine details like facial features, or you prefer flat, even fabric without raised texture. SC takes longer but produces sharper, more detailed results at the same finished size.
