Formula:

Stitch Length = Length of 100 Number of loops / 100 Calculates Yarn Count from GSM only:

  1. Terry = 6240 + GSM
  2. Single Jerssy= 4300 + GSM
  3. Pique = 5200 + GSM 4. Fleece = 7200 + GSM

5. Interlock = 7200 + GSM 6.1×1 Rib = 6000 + GSM

  • Lacost 5500 + GSM
  • 2×2 Rib = 6250 + GSM
  • Terry = 6240 + GSM

Some Other Tricks:

  1. Single Jerssy = (-0.141x GSM) +50.22
  2. Pique (-0.146 x GSM) +57.16
  3. Double Lacost = (-0.167 x GSM) +64.36
  4. 1×1 Rib = (-0.123 x GSM) +54.57
  5. Interlock = (-0.206 x GSM) +80.56
  6. Lycra 1×1 Rib = (-0.119 x GSM) +59.12
  7. Lycra 2×2 Rib = (-0.108 x GSM) +56.62
