Hall B is a highly space-efficient venue.

Located on the first floor in the North Wing of Coex, Hall B consists of an exhibition hall (7,290 m²) and a swing space. The hall can be partitioned into two sections, with room for up to 360 booths. The few pillars in the hall are spaced out in wide enough intervals to grant maximum flexibility in managing the area. As it can be combined with Hall A through the swing space, Hall B is capable of hosting major exhibitions and large-scale meetings, as well as various events and programs.
