The linear diameters D/sub r/ of the inner ring (r) and pseudo-ring (rs) structures in spiral galaxies of different morphology types and stage Sab to Sd (2< or =T< or =7) in the revised Hubble system are calibrated by means of approx.150 galaxies which have the best determined distance moduli ..mu../sup w//sub 0/(..lambda../sub c/) and ..mu../sup w//sub 0/(V/sub M/) previously derived from tertiary indicators (B/sup 0//sub T/, D/sub 0/) via the corrected luminosity index ..lambda../sub c/ and from the 21 cm line widths via revised versions of the Tully-Fisher relations.
