Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Uniform isotropic shrinkage assumption. Use measured clay-and-firing shrinkage; glaze and warping are excluded.
Example Calculation
- Desired fired dimension: 10 cm
- Linear shrinkage: 12 %
For a 10 cm fired dimension at 12% linear shrinkage, form about 11.364 cm wet.
Frequently asked questions
How do I use this calculator?
Enter desired fired dimension, linear shrinkage. The result updates automatically. Use Reset to restore the example values.
What method does it use?
wet dimension=fired dimension/(1−shrinkage); isotropic volume factor=(1−shrinkage)³.. Uniform isotropic shrinkage assumption. Use measured clay-and-firing shrinkage; glaze and warping are excluded.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
