A method for the characterization of coincidence cells is proposed for hexagonal crystals. It is based on a simple formulation of the orientation relationships for coincidence site lattices. Therefore tables of coincidence orientation are established for different axial ratios with rational values of (c/a)2. Possible practical cases of coincidence are characterized by their comparison with these tables. This comparison is preferably performed using the description given by a rotation angle of 180°.
