We re-examine the usual expectations for multipolar plasmon modes of a simple-metal sphere within a classical picture. We show that according to rigorous solution of the eigenvalue problem the complex eigenfrequencies of plasmon modes can be attributed to the sphere of size larger than the minimum size at given multipolarity, the feature not known from widely used "low radius limit".
