Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Exposed edge = rectangular perimeter − hidden-edge deduction. Required fascia = exposed edge × courses. Full boards and fastener packs are rounded up after the allowance.
FAQ
Deck Fascia Calculator questions
Should the house-side ledger edge be excluded?+
Usually it is not exposed fascia, so enter its length as a deduction when appropriate.
Why might two fascia courses be needed?+
Deep framing, stacked trim details or wide rim assemblies can require more than one board height.
Are fascia joints included?+
The cut and joint allowance helps cover waste, but actual joint layout depends on stock lengths and framing support.
