The diffraction patterns of coarse grained materials are compared to specimens with crystallite sizes of less than 1 µm characterized by diffraction spots. Based on an analysis of spot intensities it is shown that for: (a) an at-random distribution of crystallite orientations and (b) under the assumption of specific crystallite shapes it becomes possible to evaluate the distribution N(l) of linear crystallite dimensions (0.1 µm < l < 20 µm) from measured spot intensity distributions z(i).
