We present a measurement of the mass, total width and leptonic width of the ψ(3770) meson. Results were obtained using data collected at the ψ(3770) resonance with the KEDR detector at the electron-positron accelerator complex VEPP-4M. The commonly used fitting procedure does not contain interference ψ(3770) resonance and non-resonant DDbar cross section. In our analysis we used a description of the ψ(3770) resonance shape including interference.
