In addition to the programme of discovery physics, the experiments at the hadron colliders Tevatron and LHC will continue the studies of precision physics successfully carried out during the last decade at LEP, SLC and the Tevatron. From this point of view, the process of single W-boson production can play a crucial role, since it can be used to extract improved precise measurements of the W-boson parameters (mass and width) and can be also exploited to monitor the collider luminosity or determine the parton distribution functions. With these motivations in mind, I will review the state of the art of precision calculations for single W-boson production in hadronic collisions, with particular emphasis on recent progress in the area of electroweak and multiphoton radiative corrections. I will present some details of the comparison of the recently developed event generators HORACE and WINHAC and I will discuss the impact of higher-order QED effects on the precise determination of the W mass. I will also review very recent developments in the calculation of QCD corrections to single W-boson production and I will emphasize the importance of combining electroweak and QCD calculations for future precise measurements at the Tevatron and LHC.
