The outer rim of Leibnitz is roughly circular, with a prominent outward bulge along the southern face. It has received some impact erosion and wear, with several tiny craters lying along the edge and the inner wall. The rim to the east and southeast has been somewhat modified by the Davisson and Finsen craters.
Much of the interior floor of this walled plain has been resurfaced by lava, leaving a level, nearly featureless surface with the same low albedo as the dark lunar mare to the northwest. However the southeastern part of the floor is more irregular, and the albedo matches the surrounding terrain. The dark floor is covered in places by streaks of ray material, and several tiny craterlets. The small crater 'Leibnitz X' near the northwest inner wall has been flooded by lava, leaving only a roughly circular rim projecting above the surface.
