Sizes are nominal footprints in feet. External dimensions can differ slightly from the headline size because of cladding overhang and panel construction — the internal heights listed are the real usable measurements.
Timber is measured before machining — that "sawn" size is the nominal figure. Planing it smooth and cutting the tongue-and-groove profile removes a few millimetres, so a 16mm nominal board finishes at around 12mm, and a 24mm nominal floor board finishes at around 18mm.
Every timber manufacturer works this way — but most only quote the bigger nominal number. We publish both, so you can compare buildings on the wood you actually get, not the wood it started as.
Same build, same spec — pick the footprint that fits.
