We analyze the recent electron-proton scattering data from Mainz using a dispersive framework that respects the constraints from analyticity and unitarity on the nucleon structure. We also perform a continued fraction analysis of these data. We find a small electric proton charge radius, rₑᵖ = 0.84₋₀.₀₁⁺⁰.⁰¹ fm, consistent with the recent determination from muonic hydrogen measurements and earlier dispersive analyses. We also extract the proton magnetic radius, rₘᵖ = 0.86₋₀.₀₃⁺⁰.⁰² fm, consistent with earlier determinations based on dispersion relations.
