Weaving Calculations

This is some basic information in calculating ones yardage for a project.
Will add other, more detailed records, in the future.

WARP
Figuring the yardage of yarns needed for warp

  • Warp length:
  • (in inches) __________________
  • Add loom waste
  • + ____________________
  • Warp length:
  • (in inches) __________________
  • Add loom waste
  • + ____________________
  • Equals:
  • = ____________________
  •  
  •  
  • Add ___ % for shrinkage
  • + ____________ Depending on fiber
  • Guide string: wind-off
  • = ____________ Length for each warp thread
  • Multiply by Width x e.p.i.
  • ___ x ___ = ____
  • Divide by 36
  • Yards needed for warp = ____________

WEFT
Figuring the yardage of yarns needed for weft

  • Weft Width
  • = ____________
  • Multiply by p.p.i.
  • x ____________
  • Equals:
  • = ____________________
  •  
  •  
  • Multiply by length
  • x ____________
  • Equals:
