The total width $\\Gamma_t$ is extracted from the partial decay width $\\Gamma(t\\to Wb)$ and the branching fraction $\\mathcal{B}(t\\to Wb)$. $\\Gamma(t\\to Wb)$ is obtained from the $t$-channel single top quark production cross section and $\\mathcal{B}(t\\to Wb)$ is measured in $t\\bar{t}$ events. For a top mass of $172.5\\;\\rm GeV$, the resulting width is $\\Gamma_t = 2.00^{+0.47}_{-0.43}$ GeV.
