Skirting & Trim Length
Skirting, cornice, chair rail or quarter-round for several rooms: perimeter minus openings, sticks of your stock length with or without offcut reuse, and cost.
Run per room and in total, sticks by first-fit layout or whole sticks per wall, the waste-adjusted figure, inside corner count, cost at your price, and a CSV per room.
Example: Living 5.2 × 4.1 m with a 0.9 m door and a 1.8 m opening, Bedroom 4 × 3.5 m with a door: 30 m of run; with 3.6 m sticks and 10 % waste that is 10 sticks (offcuts reused first-fit).
