Based on data samples taken by the BESIII, Belle, KEDR and LHCb experiments, many measurements on conventional charmonium spectroscopy were finished in the past years. Some of recent results, such as precise measurements of J/ψ and ψ(2S ) masses, the J/ψ decay width, the J/ψ and ψ(2S ) electronic widths, two-photon width of χc0,2 meson, the χc1,2 resonance parameters with the decays χc0,2 → J/ψµ+µ−, the ηc resonance parameters and observations of X(3823) and X*(3860), were reported.
