How the C2C graph generator works
Every square in the graph is one corner-to-corner tile. Upload a picture, choose the width in tiles and the number of yarn colours, and the generator matches each tile to one of your colours, cleans up lone tiles so you have fewer colour changes, and writes out the count for every diagonal row.
How big will my C2C blanket be?
| Blanket | Tiles | DK | Worsted / aran | Chunky |
|---|---|---|---|---|
| Baby blanket | 30 × 36 | 23 × 27 in | 30 × 36 in | 39 × 47 in |
| Lapghan | 36 × 48 | 27 × 36 in | 36 × 48 in | 47 × 62 in |
| Throw | 50 × 60 | 38 × 45 in | 50 × 60 in | 65 × 78 in |
| Twin | 66 × 90 | 50 × 68 in | 66 × 90 in | 86 × 117 in |
Your own tile size depends on your hook and tension. Crochet a 4 × 4 tile swatch, measure it, and type the tiles per 4 inches into Settings to see your exact finished size.
Tips for a clean C2C picture
- Use 4 to 8 colours. More colours means more bobbins and more ends to weave in.
- Turn Clean-up up to Strong to merge single stray tiles into the colours around them.
- Crop tightly around the subject so it fills the blanket.

Questions
What is a C2C graph?
A corner-to-corner (C2C) graph is a grid where every square is one C2C tile, usually 3 double crochets. You work it diagonally from one corner, so the pattern lists how many tiles of each colour go in every diagonal row.
How do I turn a photo into a C2C graph?
Upload the photo above, choose how many tiles wide you want the blanket and how many colours, and the generator makes the graph with C2C row counts for every diagonal. Download the PDF to print it.
How many squares wide should my C2C blanket be?
With worsted yarn a C2C tile is about 1 inch, so the number of tiles is roughly the size in inches: about 30 × 36 for a baby blanket and 50 × 60 for a throw. DK yarn makes smaller tiles; chunky makes bigger ones.
How do I read the C2C row counts?
Row 1 is the single tile in the bottom right corner. Each row adds one tile until you reach the widest diagonal, then the rows get shorter. The counts read along each diagonal, like "3 white, 2 navy, 4 white".
Can I make a graphgan or tapestry pattern instead?
Yes. Switch the pattern style from corner to corner to row by row and you get single crochet or graphgan rows, worked flat or in the round.
Is it free?
Yes, for graphs up to 80 × 80 tiles with up to 16 colours, with written C2C row counts and a printable PDF. Pro removes the limits for big bedspreads.
