Recent measurements of W and Z boson properties at the Tevatron proton anti-proton collider are presented. A b-specific jet energy scale using Z --> bb-bar signal has been extracted from CDF Run II data. The leptonic decay of Z boson in pairs of e+e- has been studied by both CDF and D0 experiments to measure the Z boson differential cross section. Leptonic decay of W boson has also been used, by D0 experiment, to measure the muon charge asymmetry.
