Clay Shrinkage Calculator: Determine Ceramic Firing Shrinkage Percentage

Calculate Your Clay's Linear Shrinkage

Enter the length of your clay piece before drying/firing (e.g., in cm or inches).
Enter the length of your clay piece after firing (use the same units as initial length).

Accurately predict clay shrinkage from wet to fired stages with our online calculator. Essential for potters, ceramists, and sculptors to prevent warping and cracking. Input your initial greenware length and final fired length to get the precise shrinkage percentage, vital for successful ceramic projects.

Formula:

The formula for linear clay shrinkage percentage is:

Shrinkage % = ((Linitial - Lfired) / Linitial) * 100

  • Linitial: The initial length of the clay piece (greenware/wet clay).
  • Lfired: The final length of the clay piece after firing (bisque or glaze fired).
