1. A set of similar or essentially identical building panels, comprising:
a first mechanical locking system at respective parallel and opposite third and fourth edges, being long edges of the panels, the first mechanical locking system comprising, at the third edge, a first tongue groove configured to receive a first locking tongue of a fourth edge of an adjacent panel by a folding displacement of the adjacent panel for horizontal and vertical locking between two adjacent building panels, and
a second mechanical locking system at respective parallel and opposite first and second edges, being short edges of the panel shorter than or equal to the long edges of the panel, configured to cooperate for horizontal and vertical locking of two adjacent building panels,
wherein an upper edge portion of the third edge comprises a first lower lip portion configured to cooperate with a first upper lip portion of an upper edge portion of the fourth edge of an adjacent panel when said third and fourth edges are assembled in a locking position,
wherein a first dimension extends in a vertical direction between an upper surface of the first tongue groove and the first lower lip portion, and wherein a second dimension extends in the vertical direction between an upper surface of the first locking tongue and the first upper lip portion, and
wherein the second dimension is smaller than or equal to the first dimension.
