About this calculator

Skirting board quantity starts with a room’s full wall perimeter, then subtracts every gap the board doesn’t need to cover — doorways, open archways and any built-in feature that meets the floor without a wall behind it — leaving the actual running length of board required. Because skirting is sold in fixed-length pieces, usually bundled into packs, that running length is then divided by the length per pack and rounded up to determine how many packs to buy.

DIY renovators and joiners run this calculation before a materials trip because skirting waste adds up fast: buying by eye typically means either an emergency second trip when a pack runs short, or paying for a full extra pack over a shortfall of just a metre or two — and the doorway deductions are the step most commonly forgotten, inflating the estimate.

This calculator takes your room’s wall measurements, deducts your doorway widths, and returns the exact running metres of skirting board needed along with the number of packs to buy.
