Why is lumber not actual size?

Maybe you've noticed that lumber sizes are often misleading. The "nominal" cross-section dimensions of a piece of lumber, such as 2 X 4 or 1 X 6, are always somewhat larger than the actual, or dressed, dimensions. The reason is that dressed lumber has been surfaced or planed smooth on four sides (called S4S).

Nominal measurements traditionally refer to the size of the board when it was first rough cut, before it was dried and planed (smoothed). Actual measurements are the actual final size of the lumber after it has been dried and planed. If the final product has been planed on all four sides, it will be denoted as S4S.

This pressured further compromise because thinner 2x4s were a way to compete in price with wood alternatives.
