Abstract		Thickness of a single fat electric double layer is considered. The electrostatic mean field and the excluded volume effects are taken into account. A simple statistical mechanical approach is used where the particles in the solution are distributed over a lattice with an adjustable lattice constant. Different sizes of the ions are described by different values of the lattice constant. A measure is introduced that describes an effective thickness of the electric double layer, a distance where the density of the number of counterions drops to a chosen fraction of its maximal value. It is shown that the effective thickness of the electric double layer increases with increasing counterion size.
