We describe the results of two studies recently undertaken, aimed at quantifying the properties of single and nested stellar bars in well-matched samples of Seyfert and non-Seyfert galaxies. We find that Seyfert host galaxies are more often barred than non-Seyferts. Sub-kpc bars in nested systems are probably confined to within the inner Lindblad resonance(s), and have a different formation and evolution history from large-scale bars. we do not find a substantial prevalence of stellar sub-kpc bars in Seyferts.
