Clay Shrinkage Calculator
Calculate linear shrinkage from wet and fired dimensions and estimate the wet size needed for a target fired size.
Formula
Shrinkage percent = (wet size - fired size) / wet size x 100.
About the Clay Shrinkage Calculator
Calculate linear shrinkage from wet and fired dimensions and estimate the wet size needed for a target fired size. This tool keeps the requested measurements separate and applies the named method instead of substituting an unrelated general estimate.
How the Clay Shrinkage Calculator Works
The retained fraction from the measured test piece is applied inversely to the desired finished dimension.
Formula
Shrinkage percent = (wet size - fired size) / wet size x 100.
The calculation runs in your browser. Values are validated for required ranges, compatible units, and method-specific restrictions before results are displayed.
Required Inputs
- Wet test dimension (required) - enter in mm.
- Fired test dimension (required) - enter in mm.
- Desired fired dimension (required) - enter in mm.
Results Reported
The result panel reports the final answer and the intermediate quantities needed to check the calculation:
- Linear shrinkage (%)
- Retained dimension (%)
- Required wet dimension (mm)
- Test-piece dimension loss (mm)

Accuracy and Limitations
Shrinkage varies by clay body, direction, thickness, forming method, drying, firing schedule, and kiln atmosphere. Test the actual process.
Keep units consistent, use measurements that represent the actual situation, retain full precision during the calculation, and round only the final answer. Professional decisions may require current official rules, field measurements, laboratory methods, or specialist review.
