We develop a method for measuring homology classes. This involves two problems. First, we define the size of a homology class, using ideas from relative homology. Second, we define an optimal basis of a homology group to be the basis whose elements' size have the minimal sum. We provide a greedy algorithm to compute the optimal basis and measure classes in it. The algorithm runs in O(@bn^3log^2n) time, where n is the size of the simplicial complex and @b is the Betti number of the homology group. Finally, we prove the stability of our result. The algorithm can be adapted to measure any given class.
