How to Use This Calculator
  1. Select a Weave Structure: Plain Weave (1/1), Twill 2/2, Satin 5-shaft, or Basket 2/2.
  2. Enter Warp Threads for the total number of warp threads in the project.
  3. Enter Weft Picks for the total number of weft picks planned.
  4. Set Shafts Available to the number of shafts on your loom.
  5. Review the Weave Structure, Shafts Needed, and Treadles Needed results, and check Feasible on Loom? to confirm your loom can weave it.

What each input means

Weave Structure
Select the basic weave structure type
Warp Threads
Total number of warp threads in the project
Weft Picks
Total number of weft picks planned
Shafts Available
Number of shafts on your loom

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Weave Structure = 0, Warp Threads = 24, Weft Picks = 24, Shafts Available = 4 = 4 input(s) provided
  2. Calculate Weave Structure
    Weave Structure
    Plain Weave (1/1) = Plain Weave (1/1)
  3. Calculate Shafts Needed
    Shafts Needed
    2 = 2
  4. Calculate Treadles Needed
    Treadles Needed
    2 = 2
