We report on micromagnetic simulations of magnetization distributions in infinite and laterally limited ultrathin magnets of different geometries. We reveal the crucial role of the finite-size effect on magnetization states in nanowires and disks. In low-perpendicular-anisotropy nanomagnets, out-of-plane magnetization states can be achieved by varying geometry and/or lateral size of the sample.
