Why are wood dimensions wrong?
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). The nominal measurement is made before the lumber is surfaced.

When did they stop making true 2×4?
This pressured further compromise because thinner 2x4s were a way to compete in price with wood alternatives. Size standards, maximum moisture content, and nomenclature were agreed upon only as recently as 1964. The nominal 2×4 thus became the actual 1½ x 3½, imperceptibly, a fraction of an inch at a time.

about 1.5×3.5
The true measurement of a 2×4 is actually about 1.5×3. 5. When the board is first rough sawn from the log, it is a true 2×4, but the drying process and planning of the board reduce it to the finished 1.5×3. 5 size.
