Prospects for Higgs properties measurements at future colliders

Run-I at the LHC has been very successful and included the discovery of a new particle with mass of about 125 GeV compatible within uncertainties with the Higgs boson predicted by Standard Model. In this talk, the Higgs physics prospects at the high-luminosity LHC and at future colliders are presented. In particular, the ultimate precision attainable on the couplings measurements of the 125 GeV particle with elementary fermions and bosons is discussed along with prospects on self-coupling measurement.
