C2C Blanket Yarn Calculator (Corner-to-Corner Crochet)

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
