The main objective of this paper is a study of some new generalizations of Hilbert's and Hardy-Hilbert's type inequalities. We apply our general results to homogeneous functions. We shall obtain, in a similar way as Yang did in (2009), that the constant factors are the best possible when the parameters satisfy appropriate conditions.
