We study the world data on elastic electron-proton scattering in order to determine the proton charge rms-radius. After accounting for the Coulomb distortion and using a parameterization that allows to deal properly with the higher moments we find a radius of 0.895 ± 0.018 fm, which is significantly larger than the radii used in the past. © 2003 Elsevier B.V.
