How the panels are worked out
For a wardrobe the two sides are full height and depth. The top and bottom fit between the sides, so they are the width minus two board thicknesses. Shelves are set back from the front, partitions split the shelf area from the hanging area, and doors are the full height divided across the width with a small gap. The back panel uses thinner board and is split into strips if it is wider than a board.
How panels are laid out on the boards
Panels are placed in strips across each 8x4 board, tallest first, with a 4 mm gap for the saw blade. This is the kind of layout a panel saw can actually cut. Doors and drawer fronts keep their grain running the length of the board so the finish matches. Any panel longer than a board is flagged so you can plan a joint or use a 10x4 board.
