  Extended Higgs sectors appear in many models for physics beyond the Standard
Model. Current Higgs measurements at the LHC are starting to significantly
constrain them. We study their Higgs coupling patterns at tree level as well as
including quantum corrections. Our benchmarks include a dark singlet-doublet
extension and several two-doublet setups. Using SFitter we translate the
current Higgs coupling measurements for one light Higgs state into their
respective parameter spaces. Finally, we show how two-Higgs-doublet models can
serve as a consistent ultraviolet completion of an assumed single
Standard-Model-like Higgs boson with free couplings.
