We prove that, for every smooth integral complex projective surface S and every ample line bundle L , the multipoint Seshadri constant at r very general points equals $\sqrt{L^2/r}$ for every sufficiently large integer r . This resolves positively the qualitative Nagata–Biran conjecture for surfaces.
