Abstract This paper describes precision measurements of the transverse momentum $$p_\mathrm {T}^{\ell \ell }$$ pTℓℓ ($$\ell =e,\mu $$ ℓ=e,μ ) and of the angular variable $$\phi ^{*}_{\eta }$$ ϕη∗ distributions of Drell–Yan lepton pairs in a mass range of 66–116 GeV. The analysis uses data from 36.1 fb$$^{-1}$$ -1 of proton–proton collisions at a centre-of-mass energy of $$\sqrt{s}=13\,$$ s=13 TeV collected by the ATLAS experiment at the LHC in 2015 and 2016. Measurements in electron-pair and muon-pair final states are performed in the same fiducial volumes, corrected for detector effects, and combined. Compared to previous measurements in proton–proton collisions at $$\sqrt{s}=7$$ s=7 and $$8\,$$ 8 TeV, these new measurements probe perturbative QCD at a higher centre-of-mass energy with a different composition of initial states. They reach a precision of 0.2$$\%$$ % for the normalized spectra at low values of $$p_\mathrm {T}^{\ell \ell }$$ pTℓℓ . The data are compared with different QCD predictions, where it is found that predictions based on resummation approaches can describe the full spectrum within uncertainties.
