We make a Monte Carlo study on compositeness of first generation quarks and leptons using the Drell-Yan distribution in the high dielectron mass region at the Fermilab Tevatron and CERN LHC energies. The current experimental lower limits on the compositeness scale \ensuremathΛ vary from 2.5 to 6.1 TeV. In the present analysis, we assume that there will be no deviation of the dielectron mass spectrum from the standard model prediction at center-of-mass energies 2 TeV (Tevatron) and 14 TeV (LHC). We then use the contact interaction Lagrangian and find that in the LL, RR, RL, and LR chirality channels of the quark-electron currents, it is possible to extend the lower limits on \ensuremathΛ (at 95% C.L.) to a range of 6--10 TeV for 2 fb^\ensuremath-1 and 9--19 TeV for 30 fb^\ensuremath-1 of integrated luminosity at Tevatron. At LHC, the corresponding limits extend to a range of 16--25 TeV for 10 fb^\ensuremath-1 and 20--36 TeV for 100 fb^\ensuremath-1 of integrated luminosity.
