This paper presents the electron and photon energycalibration obtained with the ATLAS detector using 140 fb−1 ofLHC proton-proton collision data recorded at √s = 13 TeV between 2015 and 2018. Methods for the measurement of electron andphoton energies are outlined, along with the current knowledge ofthe passive material in front of the ATLAS electromagneticcalorimeter. The energy calibration steps are discussed in detail,with emphasis on the improvements introduced in this paper. The absolute energy scale is set using a large sample of Z-boson decays into electron-positron pairs, and its residual dependence onthe electron energy is used for the first time to further constrainsystematic uncertainties.
