This underground station has two local tracks and two side platforms.
The express tracks of the Lexington Avenue Line, used by the 4 and 5 trains during daytime hours, pass beneath the station and are not visible from the platforms.

Both platforms have their original mosaic trim line with "68" tablets on it at regular intervals and name tablets reading "68th STREET-HUNTER COLLEGE" in two lines.
On small sections of the platforms on either ends, where they were extended in the 1950s, there are blue trim lines with "68TH ST" written on it in white lettering.
Blue columns run along both platforms at regular intervals with alternating ones having the standard black station name plate in white lettering.
Both platforms have emergency exits from the lower level express tracks.

Toward the south end of the platforms are two stairs leading to the only mezzanine in the station.
It has been renovated with stainless steel fare control rails and features red accent stripes in the IND style.
Old wall lights exist but are not functional.
The waiting area inside fare control has windows that allow a full view of the platforms and tracks.
The northern half of the station without the mezzanine has very high ceilings.
