I will discuss quantitatively the tuning of composite Higgs models with partial compositeness and its interplay with the predicted Higgs mass. Three classes of models are found, characterized by different quantum numbers of the fermionic colored resonances associated with the top quark, the so-called top partners. The main result of this classification is that, in all models with moderate tuning, a light Higgs, of 125 GeV mass, requires the presence of light top partners easily accessible at the LHC.
