Description
Return clear rectangular opening after frame deductions.
Architectural openings and clearances depend on measured boundaries, projection axes and a caller-supplied comparison criterion. A positive geometric margin is distinct from demonstrating code compliance, safe access or a complete door-swing envelope. Plan lengths and projected dimensions must not be mistaken for full spatial measurements.
Return clear rectangular opening after frame deductions.
When to use this tool
Use Window Clear Opening Frame Deduction when checking the stated opening, projection or clearance geometry.
How to use the tool and how it works
- Enter outerWidth, outerHeight, left, right, top, bottom. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read clearWidth, clearHeight, area. Use the output convention below.
Return clear rectangular opening after frame deductions. Require nonnegative deductions and outer dimensions covering their sums; clearWidth/Height subtract paired sides, area multiplies them.1

}Limitations and assumptions
- This is geometric bookkeeping, not verified egress, accessibility, ventilation or building-code compliance.
- 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
Use complete measured plans and a qualified architectural/engineering assessment with the applicable requirements for real construction or safety decisions.
