Star spots have been shown to exist on a variety of stars. The growing number of observed star spot distributions on different stars - though snapshot-like - may allow the derivation of a fundamental dependency of spot patterns on stellar parameters. This paper tries to establish a connection of generic stellar parameters with the latitude of star spots based on a numerical thin-flux-tube-evolution model. The model is applied to stars with masses between 0.4 and 4.0 M_sun at evolutionary stages from PMS to early giant stages. All model stars considered have an outer convection zone with a radiative core underneath. It is shown that the rotational period is the dominant parameter in determining the star-spot latitude. Another important factor is the fractional size of the radiative core, while the evolutionary stage and the stellar mass play only a minor role.
