The W boson mass is a fundamental parameter of the Standard Model (SM) and was measured by several experiments at high energy e+e- and ppbar colliders. This parameter's measurement has the biggest impact on indirect searches for new particles or interactions, by comparing the measurement of this parameter with the prediction from the SM. It was measured recently by the ATLAS experiment at LHC, using data recorded in 2011, with a centre of mass energy of 7 TeV. I will review the thorough work that was performed in the ATLAS collaboration for this measurement and will discuss some considerations for future measurements at the LHC.
