ABSTRACT=A general computational method is introduced to estimate the Poisson's ratio for membranes with small thickness.<br/>In this method, the Poisson's ratio is calculated by utilizing a rescaling of inter-particle distances<br/>in one lateral direction under periodic boundary conditions.  As an example <br/>for the coarse grained lipid model introduced by Lenz and Schmid, <br/>we calculate the Poisson's ratio in the gel, fluid, and interdigitated phases. <br/>Having the Poisson's ratio, enable us to obtain the Young's modulus for the membranes in different phases. <br/>The approach may be applied to other membranes such as graphene and tethered membranes in order<br/>to predict the temperature dependence of its Poisson's ratio and Young's modulus.<br/>
