The double differential cross sections of the Drell-Yan lepton pair($\ell^+\ell^-$, dielectron or dimuon) production are measured as functions ofthe invariant mass $m_{\ell\ell}$, transverse momentum$p_\mathrm{T}(\ell\ell)$, and $\phi^*_\eta$. The $\phi^*_\eta$ observable,derived from angular measurements of the leptons and highly correlated with$p_\mathrm{T}(\ell\ell)$, is used to probe the low-$p_\mathrm{T}(\ell\ell)$region in a complementary way. Dilepton masses up to 1 TeV are investigated.Additionally, a measurement is performed requiring at least one jet in thefinal state. To benefit from partial cancellation of the systematicuncertainty, the ratios of the differential cross sections for various$m_{\ell\ell}$ ranges to those in the Z mass peak interval are presented. Thecollected data correspond to an integrated luminosity of 36.3 fb$^{-1}$ ofproton-proton collisions recorded with the CMS detector at the LHC at acentre-of-mass energy of 13 TeV. Measurements are compared with predictionsbased on perturbative quantum chromodynamics, including soft-gluon resummation.
