Methods of determination of the nuclear excited state radii are discussed together with the recently obtained data on the states of some light nuclei having abnormally large radii ( size isomers). It is shown that such states include excited neutron-halo states in Be-9, Be-11, and C-13 and some alpha-cluster states in C-12, Be-11, and C-13. Among the latter ones, there is the well-knownHoyle state in C-12-the structure of this state exhibit rudimentary features of alpha-particle states.
