Panel suitable as a floor, ceiling or wall panel, which panel is of a planar design having an upper side, a bottom side and side edges which comprise a first side edge provided with a first profile and a second side edge provided with a second profile, wherein the first profile and the second profile are interacting profiles that can be coupled to each other, so that a first panel can be coupled in one common plane to a second, identical panel by the interacting profiles, wherein the first profile and the second profile in coupled condition establish an interlocking with each other both in a horizontal direction and in a vertical direction, wherein the first profile and the second profile are configured to allow for a coupling of the interacting profiles of the first panel with the second panel by a downward insertion of the interacting profile of the second panel into the interacting profile of the first panel, and wherein the first profile comprises an upward tongue, and the second profile comprises a downward tongue, the respective tongues being configured to interlock with each other in coupled condition by respective interlocking surface areas, wherein the entire interlocking surface area of the upward tongue is inclined upwardly towards the first side edge, and the interlocking surface area of the downward tongue is inclined upwardly away from the second side edge, characterized in that the interlocking surface areas of both the upward tongue and the downward tongue, each comprises a section (30, 50) which is vertically divided in a plurality of area sections comprising an upper area section (32, 52) and at least one lower area section (34, 54) that are adjacent to each other, which section comprises a crease (36, 56) between the upper area section (32, 52) and the adjacent lower area section (34, 54), and preferably between each pair of adjacent area sections, and wherein at least proximal to the crease, the upper area section (32, 52) and the adjacent lower area section (34, 54) are each inclined differently under an inclination angle which is measured relative to an upward vertical vector of the panel, such that the inclination angle of the upper area section (I u) is smaller than the inclination angle of the adjacent lower area section (I L), and preferably each lower area section. wherein the first profile and the second profile are interacting profiles that can be coupled to each other, so that a first panel can be coupled in one common plane to a second, identical panel by the interacting profiles, wherein the first profile and the second profile in coupled condition establish an interlocking with each other both in a horizontal direction and in a vertical direction, wherein the first profile and the second profile are configured to allow for a coupling of the interacting profiles of the first panel with the second panel by a downward insertion of the interacting profile of the second panel into the interacting profile of the first panel, and wherein the first profile comprises an upward tongue, and the second profile comprises a downward tongue, the respective tongues being configured to interlock with each other in coupled condition by respective interlocking surface areas, wherein the entire interlocking surface area of the upward tongue is inclined upwardly towards the first side edge, and the interlocking surface area of the downward tongue is inclined upwardly away from the second side edge, characterized in that the interlocking surface areas of both the upward tongue and the downward tongue, each comprises a section (30, 50) which is vertically divided in a plurality of area sections comprising an upper area section (32, 52) and at least one lower area section (34, 54) that are adjacent to each other, which section comprises a crease (36, 56) between the upper area section (32, 52) and the adjacent lower area section (34, 54), and preferably between each pair of adjacent area sections, and wherein at least proximal to the crease, the upper area section (32, 52) and the adjacent lower area section (34, 54) are each inclined differently under an inclination angle which is measured relative to an upward vertical vector of the panel, such that the inclination angle of the upper area section (I u) is smaller than the inclination angle of the adjacent lower area section (I L), and preferably each lower area section.
