Opening Reveal Area Factor Tool

Calculate opening reveal area factor from explicit caller-supplied inputs.

Description

Return rectangular opening reveal area.

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 rectangular opening reveal area.

When to use this tool

Use Opening Reveal Area Factor when checking the stated opening, projection or clearance geometry.

How to use the tool and how it works

  1. Enter width, height, depth, includeSill. Use the units and conventions below.
  2. Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
  3. Read revealArea. Use the output convention below.

Return rectangular opening reveal area. Require nonnegative width/height/depth; area = (2*height+width+(includeSill ? width : 0))*depth.1

Limitations and assumptions

  • The top and both jambs are included; actual opening shapes, material quantities and construction suitability are not verified.
  • 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.
