Opening reveal finish area — matching openings scenarios.

How does changing matching openings affect opening reveal finish area when the other inputs stay fixed?

What this decision changes

A known internal space, existing stock or shared quantity must enter the correct subtraction or eligibility step rather than being counted as new material. Method basis: Count the exposed jamb, head and sill surfaces separately from the flat wall face around openings. Measured finish surface only; no opening construction, lintel, window or fire detail.

The focus is matching openings in the first repeated measured entry. Other repeated entries keep their own supplied values.

Reveal area = depth × (selected jamb heights + selected horizontal widths), multiplied by matching openings.Opening Reveal Finish Area Calculator

Evaluate your supplied alternatives

Start with your measured plan and selected product data. The initial values and range are illustrative. Each scenario changes only matching openings in the first repeated entry; the other entered values stay fixed.

Supplied comparison range for matching openings

Nine evenly spaced values are evaluated. Whole counts are rounded to distinct integer scenarios. Values between the listed samples are not calculated.

4 evaluated scenarios

Baseline: Exposed reveal surface — 1 m². Rejected combinations remain visible below.

Read the evaluated results

Watch the net requirement and actual order separately. Invalid rows identify combinations that cannot satisfy the method's geometric or stock-basis constraints.

  1. Replace every illustrative baseline measurement and selected product value with the inputs for your actual task.
  2. Enter a comparison range on the focused input's stated unit and quantity basis.
  3. Review rejected combinations and use the exact detail lines to distinguish measured demand from whole purchases.
  4. Open an evaluated scenario in the full calculator to save its original inputs and quantity breakdown to a browser material project.

Keep the comparison within scope

The supplied cavity, exclusion or stock eligibility must already be valid; the result does not select a safe shell, opening or construction detail.

Measured finish surface only; no opening construction, lintel, window or fire detail.

Dimensions, allowances, prices, properties and specifications are supplied by you. The tool computes their arithmetic consequences; it does not choose construction specifications or certify suitability.

Only the listed samples are evaluated. Intermediate values, alternate constraints and global cutting optimality are not inferred from the graph.
