Its 2x4 before drying and planing.

    Maybe I’m being daft (I probably am).

    After wood is planed and dried, I thought it would have gotten smaller.

    In the image, 9CM lumber measurement is smaller than 9CM metric. Meaning when 9CM lumber shrinks it’ll be even smaller than the 9CM metric.

    Have I got this backwards?
