The direction in which laminate is laid refers to the orientation of the individual panels in relation to the walls. Longitudinal direction means alignment parallel to the long side of the room. Transverse direction is parallel to the short side of the room. Diagonal describes alignments that are not at right angles to a wall. Since there is a lot of work involved in laying laminate and you want to enjoy your floor for a long time, you should consider in advance how you want to lay the floor.
