SUMMARY A general nonparametric approach to estimating the true distribution of particle sizes from either light or electron micrographs of particles of known shape is described. This method can deal with any arbitrary shape and fixed or random orientations, it assumes that the observed distribution is obtained by recording the maximum observed diameters of the particles under study. As examples, the method is applied to the distributions of both cubic particles observed in an optical metallographic specimen and spherical particles observed in a transmission electron microscope specimen.
