Abstract
The Tevatron and LEP2 experiments presently provide the most precise direct determinations of the mass and width of the W boson. The combined results are: M{sub w} = 80.394 {+-} 0.042 GeV and {Gamma}{sub w} = 2.095 {+-} 0.106 GeV. The results are in excellent agreement with the predictions of the Standard Model. In this article the latest results are described and the systematic errors which could limit further significant improvements in the precision of these measurements are reviewed.
