We investigate the measure of nodal sets for Robin and Neumann eigenfunctions in the domain and on the boundary of the domain. A polynomial upper bound for the interior nodal sets is obtained for the Robin eigenfunctions in the smooth domain. For the analytic domain, we first show the upper bounds for the interior nodal sets of Robin eigenfunctions, then show the upper bounds for the boundary nodal sets of the Robin and Neumann eigenfunctions. Furthermore, the doubling inequality and vanishing order are obtained.
