Abstract
One of the most important astrophysical parameters characterizing stellar atmosphere is the surface gravity. By a direct knowledge of mass and radius of a star it is straightforward to compute also the gravity, but unfortunately this is possible only in a few cases. For most stars, the only chance we have to infer the surface gravity is based on the analysis of spectral features: lines and continuum. In this lecture we describe some of these methods, dealing with those most commonly used in the literature.
