Effects of Kaluza-Klein excitations associated with extra dimensions withlarge radius compactifications on the Fermi constant are explored. It is shownthat the current precision determinations of the Fermi constant, of the finestructure constant, and of the W and Z mass put stringent constraints on thecompactification radius. The analysis excludes one extra space time dimensionbelow $\sim 1.6$ TeV, and excludes 2, 3 and 4 extra space dimensions openingsimultaneously below $\sim$ 3.5 TeV, 5.7 TeV and 7.8 TeV at the $90% CL$.Implications of these results for future collider experiments are discussed.Comment: 12 pages including one figur
