Description
Subtract paired insets and multiply remaining width*height for safeArea.
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.
Subtract paired insets and multiply remaining width*height for safeArea.
When to use this tool
Use Ad Copy Safe Area Remainder when checking the stated advertising layout, exposure, boundary or cost convention.
How to use the tool and how it works
- Enter totalWidth, totalHeight, insetLeft, insetRight, insetTop, insetBottom. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read safeWidth, safeHeight, safeArea. Use the output convention below.
Require nonnegative canvas dimensions/insets with horizontal and vertical inset sums within the canvas. Subtract paired insets and multiply remaining width*height for safeArea.1

}Limitations and assumptions
- The name safeArea denotes a chosen layout region, not a platform-approved or legally sufficient disclosure area.
- 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.
