Description
Divide positive muralCellSize by positive referenceCellSize for scaleFactor and multiply nonnegative referenceLength by that ratio.
Layout calculations relate dimensions, offsets, and normalized positions in a drawing or display. A numeric coordinate depends on its origin and scale, while a size allowance must use the same length unit as the object.
Divide positive muralCellSize by positive referenceCellSize for scaleFactor and multiply nonnegative referenceLength by that ratio.
When to use this tool
Use Mural Grid Cell Scale when you need a stated layout component from supplied dimensions or a normalized position.
How to use the tool and how it works
- Enter referenceCellSize, muralCellSize, referenceLength. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read scaleFactor, muralLength. Use the output convention below.
Divide positive muralCellSize by positive referenceCellSize for scaleFactor and multiply nonnegative referenceLength by that ratio.1

| muralCellSize | Mural Cell Size | Required. Finite number; strictly above 0. |
| referenceLength | Reference Length | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| scaleFactor | Scale Factor | Required. Finite number. |
| muralLength | Mural Length | Required. Finite number. |

}Limitations and assumptions
- Use compatible cell-size units; this assumes uniform scaling without surface distortion or installation allowances.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Check the assembled layout at its final scale and include installation or production allowances separately.
