Formula and assumptions
How this calculation works.
Estimate finish area from the developed exposed profile width, run lengths and separately measured end faces. Profile exposure and product coverage are inputs; no preparation, coating or structural advice.
A worked example
Illustrative inputs only. Product properties and design dimensions are not recommendations for your project.
- Developed exposed profile width
- 0.1 m
- Total exposed end-face area
- 0.02 m²
- Trim run length
- 2 m
- Matching runs
- 3
Paintable trim area: 0.62 m²
Developed profile width follows the exposed contours; it is not the bounding width of a moulding.
Before you purchase
Use dimensions from your plan and properties from your chosen product. Any design spacing, section or fixing pattern must already be specified.
