Combination of CDF and D0 Results on the W-Boson Width

The results on the direct measurements of the W-boson width, based on the data collected by the Tevatron experiments CDF and D{\O}at Fermilab during {\RunI} from 1992 to 1996 and {\RunII} since 2001 are summarized. The combination of the published {\RunI} and preliminary {\RunII} results, taking correlated uncertainties properly into account, is presented. The resulting preliminary Tevatron average for the total decay width of the W boson is: $\GW=2078\pm87 \MeV$, where the total error consists of a statistical part of $62 \MeV$ and a systematic part of $60 \MeV$.
