W mass and width from LEP

We present a measurement of the mass and width of the W boson by direct reconstruction in the qqqq and qq` ±ν` channels by of the four LEP 2 experiments, ALEPH, DELPHI, L3 and OPAL. Each experiment used about 700 pb−1 of collected data. Major systematic uncertainties are discussed.
