  We have theoretically investigated the finite system size effect of hadronic
matter on its transport coefficients like shear viscosity, bulk viscosity, and
electrical conductivity. We have used a Hadron Resonance Gas (HRG) model to
calculate the thermodynamical quantities like entropy density, speed of sound
and also the above transport coefficients. All these quantities are found to be
sensitive to finite system size effects of hadronic matter. The effect of
finite system size is found to be more when the system is at low temperatures
and gets reduced at high temperatures. Owing to the intimate linking between
system size and centrality, we have presented the centrality dependence of
transport coefficients. We have also explored to link of our results with the
macroscopic picture of hydrodynamical evolution.
