The charge-changing cross sections \(\sigma _\mathrm{{cc}}\) of \(^{10\text {-}13}\) B, \(^{11\text {-}13}\) C, and \(^{12,13}\) N nuclides on multiple targets were measured at the energy of about 170 MeV/nucleon. The point-proton radii of these nuclides were determined by comparing the experimental \(\sigma _\mathrm{{cc}}\) with the Glauber model calculation considering the charged-particle evaporation effect. For \(^{12,13}\) B, the present results are consistent with the existing experimental data deduced by different methods.
