Description
Return one-side margin/extent and remainingFraction=1-2*margin/extent.
Advertising records distinguish billable exposure, disclosure support, cyclic reporting windows, layout insets and supplied tax bases. A code-point budget or visibility-duration share does not establish readable or legally sufficient disclosure. Nominal geometry and costs require the intended platform and reporting conventions.
Return one-side margin/extent and remainingFraction=1-2*margin/extent.
When to use this tool
Use Creative Safe Margin Fraction when checking the stated advertising layout, exposure, boundary or cost convention.
How to use the tool and how it works
- Enter margin, canvasExtent. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read fraction, remainingFraction. Use the output convention below.
Require canvasExtent>0 and nonnegative equal margins with 2*margin<=extent. Return one-side margin/extent and remainingFraction=1-2*margin/extent.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| margin | Margin | Required. Finite number; minimum 0. |
| canvasExtent | Canvas Extent | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| fraction | Dimensionless fraction on the stated basis, rather than a percentage number. | Required. Finite number. |
| remainingFraction | Remaining one-dimensional extent/total extent, not remaining rectangular area fraction. | Required. Finite number. |

}Limitations and assumptions
- This is a one-dimensional inset fraction, not an area fraction or verified publisher-safe specification.
- 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
Inspect actual rendered creatives and verified delivery/billing records, and consult applicable platform, advertising and tax requirements for real decisions.
