I extract new limits on the coefficient of the effective operator generated by tree-level graviton exchange in large extra dimensions from $pp rightarrow jj$ angular distributions at LHC: $M_T > 6.8$ TeV (CMS after $2.6 fb^{-1}$ of integrated luminosity) and $M_T > 8.3$ TeV (ATLAS after $3.6 fb^{-1}$). I also compare such limits to the ones obtained using the full graviton amplitude, and discuss the impact of additional constrains arising from other datasets, such as Mono-Jet.
