THE NUMBERS, EXPLAINED
How to use this calculator.
Independent linear shrinkage fractions measured on the same pastry process. Trim is added to raw dimensions after compensating shrinkage.
Start with your inputs
Enter required baked width (cm), required baked depth (cm), observed width shrinkage (%), observed depth shrinkage (%), raw cutting trim per side (cm). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Required baked width (cm) | 24 |
| Required baked depth (cm) | 16 |
| Observed width shrinkage (%) | 20 |
| Observed depth shrinkage (%) | 20 |
| Raw cutting trim per side (cm) | 1 |
A worked example
With the example inputs above, raw width to cut (cm) is 32. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Raw width to cut (cm) | 32 |
| Raw depth to cut (cm) | 22 |
| Raw cutting area (cm²) | 704 |
How this is calculated
Raw width to cut (cm)
Divide required width by retained width fraction and add both raw trim margins.
Raw depth to cut (cm)
Apply the corresponding depth shrinkage correction and raw margins.
Raw cutting area (cm²)
Multiply raw cutting dimensions.
Symbols and units

Assumptions and limits
Independent linear shrinkage fractions measured on the same pastry process. Trim is added to raw dimensions after compensating shrinkage.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Raw width to cut (cm); Raw depth to cut (cm); Raw cutting area (cm²). The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: Independent linear shrinkage fractions measured on the same pastry process. Trim is added to raw dimensions after compensating shrinkage.
Are my inputs stored or sent to AI?
