There is no sensible reason to sell something as a dimension before it's ready to sell, a 2"x4" should be so when sold, not when curing, it takes nothing to cut oversize to accomodate for shrinkage, or to cure and cut later at the right dimension

    The carpenter or woodworker cares about how big the board is. The sawyer cares about how much of the tree it took to make that board. The lumber yard has to make those two ends meet at a price point.

    If you sell me a 2" by 4" board, you cut it 2"+the width of the sawblade, just like the metric boards are sold.

    Also is a saw really 1/2" wide? That's like 1.27cm, that's wild.

    If you really really cannot sell a true 2"x4" at the price of a 1.5" x3.5", just keep the same price and call it what it is.
