Nominal dimension (lumber)

Lumber's nominal dimensions are given in terms of green (not dried), rough (unfinished) dimensions. The finished size is smaller, as a result of drying (which shrinks the wood), and planing to smooth the wood. However, the difference between "nominal" and "finished" lumber size can vary. So various standards have specified the difference between nominal size, and finished size, of lumber.
