The runtime is shown at the top of this imax listing: https://www.imax.com/movies/m/the-hobbit-the-battle-of-the-five-armies-an-imax-3d-experience/ The filmmakers must have taken all the runtime criticism to heart with this one. No doubt it will still be too lengthy for some folks. For reference, AUJ ran at 169 minutes and DOS ran at 161 minutes.
