Electro-magnetic form factors are unique experimental tools not only in describing the internal structure of hadrons and testing QCD-inspired models but also in many areas of hadron and nuclear physics including charge-radii determination, parity-violating experiments, etc. They can be measured in space- and time-like regions via scattering and annihilation experiments, respectively. Form Factors in the time-like region are not as precisely measured as those measured in the space-like region, therefore different data samples being collected at Beijing Spectrometer III (BESIII) in the Beijing Electron Positron Collider II (BEPCII) are used for measuring time-like form factors which in turn leads to enhance the knowledge of hadrons structure. In this contribution, we report the recent results of measuring electro-magnetic form factors of baryons at the BESIII experiment.
