What is C2C Crochet?

Corner-to-corner (C2C) crochet builds your project in diagonal blocks rather than rows. Each block represents a small section of your design.

Because of this structure, yarn usage is best estimated using block-based calculations.

What This Calculator Helps You Do

  • Estimate total C2C blocks
  • Calculate yarn usage per block
  • Convert blocks into total yarn needed
  • Estimate skeins required

Best Used For

  • Pixel blankets
  • Character or emoticon designs
  • Graphghan-style crochet projects
  • Custom image blankets

How It Works

Enter your blanket dimensions and yarn settings, and the calculator will estimate:

  • Total number of blocks
  • Yarn required in meters
  • Skeins needed for completion

Why This Calculator is Useful

C2C projects often run out of yarn due to incorrect estimation. This tool helps you:

  • Plan full pixel designs accurately
  • Avoid mismatched yarn quantities
  • Scale patterns up or down easily
