Orientation determines the run length and number of board rows. Each row uses whole stock boards rounded up; this version does not optimize leftover sharing between rows or staggered butt joints. The stated gap is between boards. Reserve is added to the board count. Fasteners and substructure must be planned with the related tools and product instructions.
