Аннотация: An analysis of parameters of the 566 young star clusters in the 35 late type spiral and irregular galaxies is presented. The disposition, the sizes and the colors of the star clusters are studied, based on the multicolor surface photometry data. The ages of the young star clusters are estimated using evolutionary synthesis method. A problem of taking into account the dust contribution is discussed. Most of the clusters are located in the Inner Lindblad Resonance ring and in other resonance rings. In some ring galaxies the distances between neighbouring star clusters are similar. For some of investigated galaxies, the star clusters belonging to a given galaxy have similar ages. A correlation between age and size of star forming regions exists. The younger objects have smaller average sizes. There are no single star forming regions with sizes > 550 pc. In general, the star forming regions in a given galaxy have similar sizes. A correlation between maximal diameter of star clusters and absolute blue magnitude of parental galaxy exists.
