We determine the dielectron widths of the (1S), (2S), and (3S) resonances with better than 2% precision by integrating the cross section of e⁺e^- over the e⁺e^- center-of-mass energy. Using e⁺e^- energy scans of the resonances at the Cornell Electron Storage Ring and measuring production with the CLEO detector, we find dielectron widths of 1.252±0.004(_stat)±0.019(_syst) keV, 0.581±0.004±0.009 keV, and 0.413±0.004±0.006 keV for the (1S), (2S), and (3S), respectively.
