Fleece Yield & Yarn Calculator

Estimate clean fleece yield, yarn yardage, and felting area from raw fleece weight

Work in progress — this calculator is still under development and may not be fully accurate. Use results as a guide only.

Input Details

Dual-purpose breeds. Good balance of meat and wool production.

Skein count assumes 50 g balls. Actual yardage varies with spinning technique and twist.

~6 cm² per gram of clean fibre

Finished Felt Area (after fulling)

0.70

~4 cm² per gram of clean fibre

Notes

  • Clean yield estimates assume average grease and vegetable matter content for each breed type. Individual fleeces vary — weigh after scouring for precision.
  • Yarn yardage is a guide based on standard spinning ratios. Handspun yarn varies significantly with spinner technique, twist angle, and single vs. plied construction.
  • Felting area assumes wet felting with firm agitation. Needle felting and nuno felting ratios differ considerably.
