THE NUMBERS, EXPLAINED
How to use this calculator.
Fixed-orientation rectangular cutting grid; cuts have negligible kerf. Coordinates are measured from original slab edges and list complete piece boundaries after trim.
Start with your inputs
Enter slab width and depth (cm), piece width and depth (cm), edge trim 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 |
|---|---|
| Slab width and depth (cm) | 24,18 |
| Piece width and depth (cm) | 4,3 |
| Edge trim each side (cm) | 0 |
A worked example
With the example inputs above, piece count is 36. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Piece count | 36 |
| Width cut coordinates (cm) | 0, 4, 8, 12, 16, 20, 24 |
| Depth cut coordinates (cm) | 0, 3, 6, 9, 12, 15, 18 |
How this is calculated
Piece count
Fit whole pieces along each trimmed dimension and multiply.
Width cut coordinates (cm)
List width boundaries beginning at edge trim.
Depth cut coordinates (cm)
List depth boundaries beginning at edge trim.
Symbols and units
- a
- Slab width and depth (cm)
- b
- Piece width and depth (cm)
- c
- Edge trim 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
Fixed-orientation rectangular cutting grid; cuts have negligible kerf. Coordinates are measured from original slab edges and list complete piece boundaries after trim.
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?
Piece count; Width cut coordinates (cm); Depth cut coordinates (cm). 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: Fixed-orientation rectangular cutting grid; cuts have negligible kerf. Coordinates are measured from original slab edges and list complete piece boundaries after trim.
Are my inputs stored or sent to AI?
Calculations on this page happen in your browser. The separate AI question finder sends its submitted conversation to OpenAI; these calculator fields are not sent. Favourites and recent tool names are stored locally. A shared link contains the inputs you choose to include.
