  We present a dispersion theoretical analysis of the experimental data on the
electromagnetic form factors of the nucleon covering both the space- and
time-like regions. The nucleon form factors over the full range of momentum
transfers and the nucleon radius are extracted with high precision. The
statistical uncertainties of the extracted form factors and radius are
estimated using the bootstrap method, while systematic errors are determined
from variations of the spectral functions. For the proton charge radius, we
find $r_E^p = 0.840^{+0.003}_{-0.002}{}^{+0.002}_{-0.002}$~fm, in line with
previous analyses of spacelike data alone and also the muonic Lamb shift
determination.
