It should not be confused with the term Hochtaunus, in the sense used in the name of the county of Hochtaunuskreis which is only the eastern part of the Feldberg massif.

The High Taunus runs as a mountain ridge from southwest to northeast from the Middle Rhine opposite the Bingen Forest to the Wetterau before Bad Nauheim for a distance of 75 kilometres; its average widths being only 4 to 5 km.

At 7 km, the widest part of the natural region lies between Presberg and Rüdesheim am Rhein.

100 m above sea level (NHN)) in the south the ridge zone climbs rapidly and steeply to over 600 to 879 m, and rises above the plain by 400 to 600 metres (m).

In places, a parallel ridge has formed: along the Theißtal near Niedernhausen, which is bounded in the north and south by two lines of mountains.
