A method is proposed for determining the surface fractal dimensions of anisotropic pigment particles from their specific surface areas, obtained, for example, from adsorption measurements, and their principal linear dimensions. The method is applied to data obtained previously for iron oxyhydrate and ß-copper phthalocyanine pigments, and is compared with an approach outlined by Avnir, Farn and Pfeifer [J. Colloid Interface Sci., 103 (1985) 112]. © 1995.
