      Nominal Size – is the size of a piece of lumber before it is dressed and seasoned. It is used to designate a particular size piece of lumber, such as 2×4, 2×6, etc.

      Actual Size – refers to minimum acceptable size after it has been dressed and seasoned. A nominal 2*4 can have a minimum actual size of 1.5″ x 3.5″. When referring to a specific piece of lumber, the nominal size is used.

      IMPORTANT: Our cut & material lists always call out the nominal size. The actual plans however take into account the finished (actual) size.
