THE NUMBERS, EXPLAINED
How to use this calculator.
Supported layout partitions the trimmed sheet into base-by-height rectangles and cuts each diagonally into two right triangles. Does not model staggered isosceles croissant layouts or stretching.
Start with your inputs
Enter dough sheet width (cm), dough sheet depth (cm), triangle base (cm), triangle height (cm), edge trim on each side (cm). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Dough sheet width (cm) | 60 |
| Dough sheet depth (cm) | 40 |
| Triangle base (cm) | 10 |
| Triangle height (cm) | 20 |
| Edge trim on each side (cm) | 0 |
A worked example
With the example inputs above, triangles cut is 24. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Triangles cut | 24 |
| Used triangle area (cm²) | 2,400 |
| Offcut including edge trim (cm²) | 0 |
How this is calculated
Triangles cut
Count base-by-height rectangles in a fixed orientation and double for diagonal cuts.
Used triangle area (cm²)
Multiply complete rectangle count by its area.
Offcut including edge trim (cm²)
Subtract area of cut triangles from the original sheet.
Symbols and units
- a
- Dough sheet width (cm)
- b
- Dough sheet depth (cm)
- c
- Triangle base (cm)
- d
- Triangle height (cm)
- e
- Edge trim on each side (cm)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions and limits
Supported layout partitions the trimmed sheet into base-by-height rectangles and cuts each diagonally into two right triangles. Does not model staggered isosceles croissant layouts or stretching.
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?
Triangles cut; Used triangle area (cm²); Offcut including edge trim (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: Supported layout partitions the trimmed sheet into base-by-height rectangles and cuts each diagonally into two right triangles. Does not model staggered isosceles croissant layouts or stretching.
